Latest / Stuff You Should Know / What To Do With All This Nuclear Waste?
Transcript
- 0:01Speaker 1: Welcome to Stuff You Should Know, a production of iHeartRadio.
- 0:11Speaker 2: Hey, and welcome to the podcast. I'm Josh, and there's
- 0:13Speaker 2: Chuck and Jerry's here too, and this is a good
- 0:16Speaker 2: old fashioned episode of Stuff you Should Know.
- 0:21Speaker 1: D D.
- 0:26Speaker 2: Are you talking about the Green Gow? Yeah?
- 0:29Speaker 1: I mean it's just hard not to think of Homer
- 0:31Speaker 1: Simpson when you're talking about nuclear power at all.
- 0:34Speaker 2: Yeah, and nuclear waste in particular.
- 0:36Speaker 1: Right, Yeah, Like you know that little Rod flies right
- 0:39Speaker 1: into his hood, right.
- 0:41Speaker 2: This inanimate carbon Rod is the employee of the Year.
- 0:45Speaker 1: I think that's right.
- 0:46Speaker 2: So, yeah, it turns out that nuclear waste doesn't really
- 0:50Speaker 2: look like that. It certainly doesn't glow green. Probably the
- 0:53Speaker 2: closest you could get to what the Simpsons depict, and
- 0:58Speaker 2: not just the Simpsons, I think the classic movie Men
- 1:01Speaker 2: at Work featuring brothers Melio Estevez and Charlie Sheen.
- 1:04Speaker 1: Never saw it.
- 1:06Speaker 2: It's good as far as eighties comedies.
- 1:09Speaker 1: Go, it's pretty good.
- 1:11Speaker 2: And they play a lot of two live crew too.
- 1:14Speaker 1: Oh well, there you go.
- 1:15Speaker 2: Because I think it takes place in Miami. I'm not sure.
- 1:18Speaker 2: But the closest you can get to that from what
- 1:20Speaker 2: I can tell, is a sludge toxic nuclear sludge that
- 1:27Speaker 2: is described as having kind of a peanut buttery consistency.
- 1:31Speaker 2: This is gross and dangerous, you know.
- 1:34Speaker 1: Yeah, it's not as sandwich you want unless you cut
- 1:36Speaker 1: the crust off.
- 1:39Speaker 2: So for the most part, though, nuclear waste is solid,
- 1:43Speaker 2: it's like pellets of solid essentially metal material made up
- 1:49Speaker 2: of a bunch of different elements and metals and all
- 1:54Speaker 2: sorts of crud pressed together to form essentially a uranium
- 1:59Speaker 2: fuel what it starts out as, but after it undergoes
- 2:02Speaker 2: nuclear fission for five or six years, it says, I'm spent,
- 2:07Speaker 2: get me out of here, and a new fuel assembly
- 2:10Speaker 2: sprought in.
- 2:12Speaker 1: Yeah, that's right. And this is clearly the most dangerous
- 2:16Speaker 1: kind of nuclear waste We're going to go over, you know,
- 2:18Speaker 1: several different kinds of nuclear waste, but this is the
- 2:21Speaker 1: stuff that you really really got to take care of.
- 2:24Speaker 1: I mean, you got to take care of all it,
- 2:25Speaker 1: of course, but this is stuff that's super dangerous, right,
- 2:29Speaker 1: And these pellets are these little cylinders about the size
- 2:34Speaker 1: I guess it depends on your thumb, but you know,
- 2:36Speaker 1: like midway up your thumb, half a thumb.
- 2:40Speaker 2: Okay, half thumb anything but metric.
- 2:42Speaker 1: Yeah, not the thumb stump, like the actual thumb print
- 2:48Speaker 1: section of your thumb, the thumb sprout, Yeah, the thumb
- 2:51Speaker 1: sprout exactly. And you know, disposing of this stuff is
- 2:56Speaker 1: sort of the highest level of concern because we have
- 2:59Speaker 1: to do it, so we don't there's not a place
- 3:02Speaker 1: in the world that has a permanent solution for this,
- 3:07Speaker 1: even though Finland is pretty close to you know, I'm
- 3:12Speaker 1: going to put air scare quotes as you call them,
- 3:15Speaker 1: around a permanent solution, because who knows what permanent means,
- 3:18Speaker 1: you know, in fifty thousand years, and we were going
- 3:22Speaker 1: to build one of these in twenty ten, and we'll
- 3:23Speaker 1: talk about why that didn't happen. But since the nineteen forties,
- 3:27Speaker 1: we've had a lot of different kinds of nuclear waste
- 3:30Speaker 1: to dispose of, and we've been getting rid of it
- 3:34Speaker 1: and storing it in a few different ways since then.
- 3:36Speaker 1: But there's a potentially a brighter future ahead with some
- 3:39Speaker 1: pretty ingenious ideas.
- 3:41Speaker 2: Yeah, fingers crossed, because right now we're going down the
- 3:45Speaker 2: road that was proposed a long time ago, and it's
- 3:47Speaker 2: kind of a dumb, unnecessary road, and hopefully smarter heads
- 3:53Speaker 2: will prevail. But yeah, we'll get into that later. But
- 3:55Speaker 2: one thing I thought was fascinating is that there is
- 3:59Speaker 2: way less nuclear waste than you would think, right. I
- 4:02Speaker 2: think something like if you took all of the nuclear
- 4:06Speaker 2: power that you used, you Chuck used for your entire
- 4:10Speaker 2: lifetime moment of birth.
- 4:12Speaker 1: Yep, the moment you die in a couple of years.
- 4:16Speaker 2: All of it now far longer than that, I hope.
- 4:19Speaker 2: So all of that nuclear waste would be compressed to
- 4:23Speaker 2: about a hockey puck. So each of us in the
- 4:26Speaker 2: United States have a hockey puck worth of nuclear waste
- 4:29Speaker 2: assigned to us, and each of us has to figure
- 4:32Speaker 2: out what to do with that hockey puck individually. That's
- 4:35Speaker 2: the new standard.
- 4:36Speaker 1: That's right. And by the way, if people think I
- 4:38Speaker 1: do have Chuck Stradama's powers of the future, please do
- 4:42Speaker 1: not get concerned that I foretold my death in two years.
- 4:46Speaker 1: It's okay, okay.
- 4:47Speaker 2: I don't know if that erased it for everybody, but
- 4:49Speaker 2: all right. It was a good attempt.
- 4:50Speaker 1: I could to hear someone out there being like, oh, no, no, no,
- 4:53Speaker 1: Chuck said he's going to die in two years. That's
- 4:55Speaker 1: he shan't even say things like that, Lest we forget
- 4:57Speaker 1: Jared and Hugh Jackman.
- 4:59Speaker 2: I mean, I don't like you saying it, but you know,
- 5:01Speaker 2: I'm just I'm nervously laughing instead.
- 5:05Speaker 1: All right, so we should kind of quickly go over
- 5:08Speaker 1: how nuclear reactors work, even though we have a pretty
- 5:11Speaker 1: great episode on that.
- 5:12Speaker 2: But the upshot of all this is, even though each
- 5:15Speaker 2: of us just has a hockey pucks worth of nuclear
- 5:18Speaker 2: waste and it amounts to you, I think, like ninety
- 5:21Speaker 2: thousand tons, which is eye popping in the United States alone,
- 5:25Speaker 2: it's eye popping, but it's actually not that much. The
- 5:28Speaker 2: problem is, is it that it's very dangerous for a
- 5:32Speaker 2: very long time afterward, and you have to put it
- 5:36Speaker 2: in very very special places. And those special places are
- 5:40Speaker 2: essentially what we're gonna kind of go over today.
- 5:43Speaker 1: Yeah, disposing of that stuff. Yeah, we have a pretty
- 5:47Speaker 1: good episode on nuclear energy. I can't remember what it
- 5:52Speaker 1: was called, do you happen? Did you check that? I know?
- 5:57Speaker 2: The only one I can think of where we really
- 5:59Speaker 2: talked about what happens in nuclear reactors was Fukushima.
- 6:02Speaker 1: That kind of like I thought, we did one just
- 6:04Speaker 1: on creating nuclear energy.
- 6:06Speaker 2: Now I don't know, man, I don't think so.
- 6:09Speaker 1: All right, well we'll go over quickly again just how
- 6:11Speaker 1: it works, because it works how creating energy works at
- 6:16Speaker 1: a coal plant or a natural gas plant, because what
- 6:18Speaker 1: you're essentially trying to do is boil water to produce steam,
- 6:23Speaker 1: and that steam turns a turbine. But in this case,
- 6:26Speaker 1: the fuel is not coal or natural gas. It's these
- 6:30Speaker 1: little uranium two thirty five pellets, like I said, the
- 6:34Speaker 1: sort of a half of a thumb size. And you
- 6:37Speaker 1: mentioned fuel assembly, a fuel assembly, Well, you get these
- 6:41Speaker 1: little pellets, you put them inside these long fuel rods,
- 6:44Speaker 1: and then you bundle together those fuel rods and those
- 6:48Speaker 1: are the fuel assemblies. And depending on the size of
- 6:51Speaker 1: the reactor and the type, there's anywhere from one hundred
- 6:54Speaker 1: and fifty to about eight hundred of those bundled up
- 6:59Speaker 1: cylindrical fuel as fuel assemblies in the reactor.
- 7:02Speaker 2: Core, right, And they're kept underwater. And the water does
- 7:06Speaker 2: a couple of things. One, it actually helps carry out
- 7:09Speaker 2: the nuclear chain reaction that produces the heat that boils
- 7:14Speaker 2: the water, that produces the steam that turns the turbine
- 7:17Speaker 2: that creates the electricity, right, But it also keeps it
- 7:20Speaker 2: from going critical. It also cools it, so there's a
- 7:23Speaker 2: constant flow of water in and out to maintain it
- 7:27Speaker 2: at a fairly constant temperature at like one hundred and
- 7:30Speaker 2: fifteen fahrenheit or something like that. And what's great about
- 7:33Speaker 2: this is this is a it's a self contained process,
- 7:38Speaker 2: unlike burning natural gas or coal. There's no emissions. And
- 7:44Speaker 2: everybody says, hooray, no emissions, and then they say, yes,
- 7:46Speaker 2: but we also have this nuclear waste as a resultant,
- 7:49Speaker 2: and he says, oh, so that's where we stand. Nuclear
- 7:52Speaker 2: power has a lot of promise if done well, especially
- 7:57Speaker 2: with some of the advanced designs that are coming down
- 7:59Speaker 2: the Pike's not a bad energy source. It's just we
- 8:03Speaker 2: haven't figured out what to do with the nuclear fuel.
- 8:07Speaker 2: And that's such an understatement, Chuck that if you actually
- 8:09Speaker 2: once you start figuring out what we're doing with our
- 8:12Speaker 2: spent nuclear fuel, it's it's almost embarrassing that this is
- 8:17Speaker 2: what we're doing. We're just basically stashing it over here
- 8:21Speaker 2: until we can figure out what to do with it
- 8:22Speaker 2: in the long term. And we've been doing that for
- 8:24Speaker 2: half a century.
- 8:25Speaker 1: Yeah, yeah, it's been going on for a long time.
- 8:28Speaker 1: The thing is, you know, these things wear out, which
- 8:30Speaker 1: is why we have to remove you know, once you
- 8:33Speaker 1: spin that fuel, just like a lump of coal would
- 8:36Speaker 1: get spent. You got to do the same with the
- 8:40Speaker 1: nuclear stuff. So every I think five or six years
- 8:45Speaker 1: it can go before that's basically on empty. But it's
- 8:48Speaker 1: not on empty, as we'll see, because there's still a
- 8:50Speaker 1: little bit of juice left, just not enough to power
- 8:52Speaker 1: sort of the old school reactors. Right, So every year
- 8:56Speaker 1: and a half to two years, a nuclear reactor is
- 8:58Speaker 1: going to close the doors and they're gonna cycle through
- 9:02Speaker 1: about a third of their fuel assemblies and get rid
- 9:05Speaker 1: of those. And that is the really high level nuclear
- 9:09Speaker 1: waste that is the most concerning and the stuff that
- 9:12Speaker 1: we need to be the most judicious with.
- 9:15Speaker 2: Yes, very fortunately they don't just take these fuel assemblies
- 9:18Speaker 2: and toss them out back into an ever growing pile.
- 9:21Speaker 2: They kind of do, but there's a little more to it.
- 9:24Speaker 2: What they do initially is so remember these things are underwater,
- 9:28Speaker 2: and they're underwater for a reason, not just for to
- 9:32Speaker 2: carry out the chain reaction that produces power, but also
- 9:35Speaker 2: to keep them from going critical. So they're moved from
- 9:38Speaker 2: the reactor core to what are called spent fuel pools
- 9:43Speaker 2: I want to say spent fuel puels. Every time I
- 9:46Speaker 2: say that out loud, but can't. So they and they
- 9:49Speaker 2: never leave the water. They're taken down these special canals
- 9:54Speaker 2: that connect the core, the reactor core, to the spent
- 9:58Speaker 2: fuel pools. And just to add a little charm to it,
- 10:01Speaker 2: they actually attach them to the bottom of a gondola
- 10:04Speaker 2: that it through the canal. It is very cute. And
- 10:07Speaker 2: then once they get to the spent fuel pool, they're
- 10:10Speaker 2: basically dropped into this huge pool, stainless steel pool that's
- 10:15Speaker 2: about has about forty feet of water in it, and
- 10:18Speaker 2: there I don't know, I think about ten feet or
- 10:21Speaker 2: so tall. So they sink down at the bottom and
- 10:23Speaker 2: they've got twenty thirty feet of water over them and
- 10:25Speaker 2: they stay there for years because they're so hot and
- 10:29Speaker 2: they're so radioactive, it would be insane to do anything
- 10:33Speaker 2: else with them, but basically put them in the pools
- 10:35Speaker 2: and let them sit there for a while.
- 10:37Speaker 1: Yeah, you can look up a picture of a spent
- 10:40Speaker 1: fuel pool and it's really cool looking. And like you said,
- 10:45Speaker 1: I mean two to five years just for these things
- 10:47Speaker 1: to cool off. They decay a little bit as far
- 10:50Speaker 1: as the radioactivity goes, But you know, that's a process
- 10:54Speaker 1: that for the most critical stuff that takes you know,
- 10:56Speaker 1: thousands of years, so it's really just a blip of
- 11:00Speaker 1: radioactivity that decays in that two to five years. But
- 11:03Speaker 1: what they're really doing is cooling that stuff down, because
- 11:06Speaker 1: if they even pulled it out to transport it and
- 11:09Speaker 1: didn't do so in a canal, it seems like it
- 11:11Speaker 1: would just combust, right, isn't that the idea?
- 11:14Speaker 2: Yeah, a fuel assembly, especially a bunch of fuel assemblies
- 11:17Speaker 2: exposed to air, would just produce so much heat that
- 11:20Speaker 2: they would blow up. And when they blew up, remember
- 11:23Speaker 2: these are fairly recent spent fuel rods, they would release
- 11:28Speaker 2: a lot of really bad stuff like sasium one thirty
- 11:31Speaker 2: seven that spreads in the air very quickly, It settles
- 11:35Speaker 2: into the environment very quickly, it enters the food chain,
- 11:38Speaker 2: and it causes all sorts of problems when it enters
- 11:41Speaker 2: the body and it sticks around for a while. It's
- 11:43Speaker 2: one of the big problems with nuclear waste. So you
- 11:45Speaker 2: want to keep those spent fuel assemblies underwater for basically
- 11:51Speaker 2: as long as you possibly can before you put them
- 11:54Speaker 2: into basically dry dock. And this is where essentially what
- 11:59Speaker 2: I was saying, where they just toss them out back.
- 12:01Speaker 2: That's what they do, but they put them into something
- 12:03Speaker 2: called the dry cask first, and it's at a little
- 12:06Speaker 2: more technical than just throwing it into a pile, but
- 12:09Speaker 2: it's imprinciple roughly the same thing.
- 12:14Speaker 1: That's very funny to me that you keep liking it
- 12:16Speaker 1: to throwing it out back in a pile.
- 12:18Speaker 2: Because that's what they're doing. Man. Like these dry casks.
- 12:21Speaker 2: It goes from a pool to a dry cask on
- 12:23Speaker 2: the same site and they just sit there in the
- 12:26Speaker 2: dry cask like, Okay, you stay here until we can
- 12:29Speaker 2: figure out what to do with you one hundred years
- 12:31Speaker 2: from now.
- 12:32Speaker 1: So for the first couple of decades that we had
- 12:35Speaker 1: this stuff, all of it was just in those cooling pools.
- 12:39Speaker 1: But those pools started to fill up. They're all on site,
- 12:41Speaker 1: you know, it's not like they have to transport them
- 12:44Speaker 1: except you know, very locally via canal. And then they said, hey,
- 12:49Speaker 1: these pools are filling up. We got to come up
- 12:50Speaker 1: with a better way. They started looking into the dry
- 12:54Speaker 1: cask method in the seventies and I think in eighty
- 12:56Speaker 1: six in the United States at the Surrey Nuclear Power
- 12:59Speaker 1: Plant in Virginia is where we had our first dry
- 13:02Speaker 1: storage facility and these casks are about twenty feet tall,
- 13:07Speaker 1: eight feet in diameter the way about one hundred tons,
- 13:10Speaker 1: and in that cask is several dozen of those fuel assemblies.
- 13:13Speaker 1: And again those fuel assemblies are made up of the
- 13:15Speaker 1: individual fuel rods that are holding the pellets, So several
- 13:19Speaker 1: dozen of those stacked together sealed inside a canister. They
- 13:23Speaker 1: bolt it shut, suck out the air, and replace it
- 13:26Speaker 1: with the inert gas. And then that steel canister is
- 13:30Speaker 1: surrounded by a thick concrete wall and they throw it
- 13:33Speaker 1: out back right.
- 13:35Speaker 2: They stand it up out back, and the inert gas
- 13:38Speaker 2: x as a coolant rather than using water, which would
- 13:41Speaker 2: corrode things. The inert gas can also absorb the radiation
- 13:44Speaker 2: and the heat. And then the concrete they use is
- 13:47Speaker 2: like very special concrete with polymer fibers and added boron
- 13:51Speaker 2: to make it even denser. And then they also mix
- 13:54Speaker 2: in magnetite and b baryte to essentially absorb radioactive particles.
- 14:00Speaker 2: So it's like the dry casks are pretty good as
- 14:03Speaker 2: far as I know, though they're only rated for about
- 14:06Speaker 2: one hundred years of storage. After that, they're like, we're
- 14:09Speaker 2: not guaranteeing anything. And so I think you said the
- 14:13Speaker 2: first one was sealed up in nineteen eighty six, So
- 14:16Speaker 2: we're at forty years essentially already ticking off the clock
- 14:22Speaker 2: for those earliest dry casks that were sealed, which, when
- 14:26Speaker 2: you start to think of it like that, like it
- 14:30Speaker 2: makes this like getting to a solution of what to
- 14:34Speaker 2: do long term permanent storage essentially how important it is
- 14:40Speaker 2: to do it as soon as possible, because if we
- 14:43Speaker 2: don't figure out exactly how to do it and then
- 14:46Speaker 2: start building it, that sixty years is going to come
- 14:49Speaker 2: and go quicker than we think. That's a long time
- 14:52Speaker 2: to design something that's one of probably the most persistent
- 14:55Speaker 2: problems that the world faces environmentally spent nuclear fuel.
- 15:01Speaker 1: Yeah, for sure. Right now, the US Nuclear Regulatory Commission
- 15:06Speaker 1: NRC is looking at applications for a couple of larger
- 15:11Speaker 1: storage sites here in the US for those dry casts,
- 15:13Speaker 1: one in New Mexico and one in Texas. These are
- 15:16Speaker 1: called consolidated interim storage sites. Again because it's just you know, temporary,
- 15:22Speaker 1: and I think all over the world about seventy percent
- 15:25Speaker 1: of the fuel that's used up is in pools, about
- 15:29Speaker 1: thirty percent is in these dry casks, and you know,
- 15:35Speaker 1: these things supposedly are built to withstand natural disasters and
- 15:38Speaker 1: things like that. But like you said, like they're stored
- 15:42Speaker 1: either on or near the surface. It's not like they're
- 15:44Speaker 1: buried in bedrock, which is we'll see, is maybe a
- 15:46Speaker 1: more permanent solution. And in fact that's that's the one
- 15:50Speaker 1: that the US was working on inside the Yucka Mountain
- 15:54Speaker 1: and Nevada, and it had NRC and EPA approval, but
- 15:58Speaker 1: Nevada said, Nope, we don't want that here. Obama canceled
- 16:03Speaker 1: it in twenty ten, and so far we don't have
- 16:06Speaker 1: a new sort of again scare quote permanent solution here
- 16:11Speaker 1: in the US.
- 16:12Speaker 2: Yeah, the big problem is in nineteen eighty seven, Congress
- 16:15Speaker 2: said Yucka Mountain is the only site that the DOE
- 16:19Speaker 2: and the NRC can use to dispose of nuclear waste.
- 16:23Speaker 2: You can't put it anywhere else geologically for long term storage.
- 16:28Speaker 2: And then they never went back and said, well, since
- 16:31Speaker 2: we're not going to put it Yucka Mountain, we'll do
- 16:33Speaker 2: it here instead. So it's just totally in limbo. So
- 16:37Speaker 2: in the interim literally, these interim storage sites, like you said,
- 16:40Speaker 2: in Texas and New Mexico, that's kind of the next
- 16:43Speaker 2: big hope after the dry casks. I think the one
- 16:46Speaker 2: in New Mexico will be capable of containing one hundred
- 16:49Speaker 2: and twenty thousand tons of spent nuclear fuel, which is
- 16:53Speaker 2: a lot, especially considering that the US has only about
- 16:56Speaker 2: ninety thousand tons of spent fuel total. But we're also
- 17:00Speaker 2: adding about two thousand tons a year, so in fifteen years,
- 17:03Speaker 2: New Mexico would be full up. So again, you kind
- 17:07Speaker 2: of see how this clock is ticking, because it's not
- 17:09Speaker 2: like anyone saying, well, let's wait on nuclear power any
- 17:12Speaker 2: further until we figure out what to do with this.
- 17:14Speaker 2: They're just it's just a go go go swinging kind
- 17:17Speaker 2: of industry.
- 17:18Speaker 1: You know, maybe we should go go go on a break. Yeah,
- 17:23Speaker 1: and I promised talk of Finland earlier, and maybe we'll
- 17:25Speaker 1: pick up with that right after this good look up
- 17:36Speaker 1: with Joe shoe on cho.
- 17:41Speaker 2: Stuff.
- 17:41Speaker 1: You shit, all right, So we mentioned Finland early on
- 17:48Speaker 1: as being kind of the only place in the world
- 17:50Speaker 1: now that is close to being done with a again
- 17:55Speaker 1: scare quote permanent solution. And the reason we keep saying
- 17:57Speaker 1: scare quotes is because you know, you sent me some
- 18:01Speaker 1: information that was like, hey, nobody knows what's going to
- 18:04Speaker 1: happen in thousands and thousands of years, so you can't
- 18:07Speaker 1: really call it permanent when there's climate change and potential
- 18:10Speaker 1: like asteroid impacts and things like that that like, we
- 18:13Speaker 1: just don't know what's coming our way, so you can't
- 18:16Speaker 1: really say it's permanent, but they're calling it permanent even so.
- 18:21Speaker 1: This one is called on Collo, which means cavity or pit,
- 18:25Speaker 1: and it's the first on planet Earth a geologic repository
- 18:30Speaker 1: where supposedly, you know, they say that you can store
- 18:34Speaker 1: this stuff, you know, close to fifteen hundred feet down
- 18:37Speaker 1: under the earth in the bedrock, and that stuff's been
- 18:41Speaker 1: there for millions of years, so this stuff should be
- 18:42Speaker 1: pretty good down there.
- 18:44Speaker 2: Yeah, And I mean they're like in the bedrock. They're
- 18:46Speaker 2: talking about fourteen hundred and thirty feet down, which for reference,
- 18:51Speaker 2: is two hundred and twenty times deeper than the depth
- 18:54Speaker 2: of an Olympic swimming pool. The spent fuel assemblies are
- 18:58Speaker 2: put into steal canisters and then just to show off,
- 19:01Speaker 2: Finland surrounds them with a two inch thick layer of
- 19:05Speaker 2: copper because copper won't corrode in the anaerobic conditions down
- 19:09Speaker 2: fourteen hundred and thirty feet under the ground. They're putting it.
- 19:13Speaker 2: Once they get to that fourteen hundred and thirty feet depth,
- 19:16Speaker 2: they go into shafts that are another thirty feet deep,
- 19:19Speaker 2: which is four point six times deeper than an Olympic pool,
- 19:23Speaker 2: and then they stack the canisters one on top of
- 19:25Speaker 2: each other. Finally they top off that thirty foot deep
- 19:29Speaker 2: shaft and then they fill them with bentonite, which is
- 19:32Speaker 2: a clever thing to add because it's it's compressed clay
- 19:36Speaker 2: that essentially remember those little dinosaur sponges that were really
- 19:40Speaker 2: tiny and then you drop water on them and they
- 19:42Speaker 2: turn into like a full size Tyrannosaurus rex. It's like that,
- 19:46Speaker 2: but it's the clay version of that. When it makes
- 19:48Speaker 2: contact with water, it expands, and as it expands, it
- 19:51Speaker 2: will form a seal around the canisters. And we just
- 19:55Speaker 2: have to hope that they did the math correctly and
- 19:57Speaker 2: it doesn't pop the cannisters open from the surrounding pressure.
- 20:00Speaker 1: Sure, I did not get the memo that we have
- 20:03Speaker 1: abandoned Big Max in favor of I guess Olympic pools.
- 20:08Speaker 1: What happened pool means nothing to me.
- 20:12Speaker 2: I just you know, it's just six and a half
- 20:15Speaker 2: feet deep.
- 20:16Speaker 1: Oh okay, So they know it means something to me,
- 20:19Speaker 1: a big mac.
- 20:20Speaker 2: I know it does, but I don't know. Okay, I'll
- 20:22Speaker 2: bring back the Big Max.
- 20:24Speaker 1: Well we don't. We can't pause for you to do
- 20:26Speaker 1: that mass.
- 20:27Speaker 2: No, No, I mean in the future. Okay, okay, I'll
- 20:29Speaker 2: bring it back for you here there, all right, Okay.
- 20:31Speaker 1: It's just a little worried. I thought maybe an email
- 20:35Speaker 1: got by me.
- 20:36Speaker 2: Well, Jerry commanded I leave the Big Max alone. I
- 20:39Speaker 2: think you were so really on that. Yeah, she said,
- 20:41Speaker 2: it's old Josh and tired.
- 20:43Speaker 1: Oh no, yeah, and you how about Olympic pools?
- 20:47Speaker 2: She said, I don't care as long as it's not
- 20:48Speaker 2: Big Max.
- 20:51Speaker 1: So that side in Finland can store three thousand canisters,
- 20:56Speaker 1: which is enough to handle Finland. They have five nuclear reactors,
- 20:59Speaker 1: and they said, hey, hey, the whole operational life of
- 21:01Speaker 1: these things, and we'll get to operational life of the
- 21:05Speaker 1: whole reactor site. Because you know, you can't make those
- 21:10Speaker 1: go forever either. You've got to shut those things down eventually.
- 21:13Speaker 1: But Finland can take care of all their business. They
- 21:16Speaker 1: said one hundred and twenty years or so to fill
- 21:18Speaker 1: that thing completely. It'll last one hundred thousand years, and
- 21:22Speaker 1: after one hundred thousand years. The idea is that it's
- 21:25Speaker 1: no longer radioactively dangerous.
- 21:27Speaker 2: Right, which is just wrong. It depends on what source
- 21:31Speaker 2: you go to, and it's not clear like ones from
- 21:34Speaker 2: one side and ones from another side. It really depends
- 21:37Speaker 2: on the source. Some people say nuclear waste is really
- 21:40Speaker 2: just dangerous for the first few decades, right. Other people
- 21:44Speaker 2: say one thousand years. Other people say tens of thousands
- 21:46Speaker 2: of years. Other people point out that an isotope of
- 21:50Speaker 2: uranium I think two thirty six or eight has a
- 21:54Speaker 2: half life of four point five billion years, So it
- 21:58Speaker 2: depends on who you talk to just how long the
- 22:01Speaker 2: stuff is really toxic for. But it seems like the
- 22:04Speaker 2: stuff that the people are most concerned of are things
- 22:07Speaker 2: like iodine one twenty nine, which has a half life
- 22:11Speaker 2: of fifteen million years. It's not good. But then on
- 22:14Speaker 2: the other hand, you have caesium one thirty one. I
- 22:17Speaker 2: think I mentioned earlier that that is really easy to
- 22:21Speaker 2: get into the environment, so it causes a lot of problems.
- 22:24Speaker 2: So does iodine one twenty nine, but it has a
- 22:26Speaker 2: half life of I think like thirty years, so as
- 22:29Speaker 2: long and a lot of the worst stuff actually goes
- 22:32Speaker 2: away while it's in those pools for the first few years.
- 22:35Speaker 2: So it really kind of depends on what element or
- 22:39Speaker 2: isotope you're worried about, whether it's safe after however many
- 22:43Speaker 2: years or not, or if it ever will be safe
- 22:46Speaker 2: under anything but geological deep time. You know.
- 22:49Speaker 1: Yeah, I wonder if they just said, I don't know,
- 22:53Speaker 1: one hundred thousand years sounds like a long time. Just
- 22:55Speaker 1: put that down.
- 22:56Speaker 2: You know. You get the impression on some of this
- 22:59Speaker 2: that they are saying that because no one will care,
- 23:02Speaker 2: Like you would think that, I mean, this is some
- 23:04Speaker 2: really studied science, so you would think that it would
- 23:07Speaker 2: be like figures bandied about everywhere, like, oh, this is
- 23:10Speaker 2: how long nuclear waste is dangerous for, you know, and
- 23:14Speaker 2: this is why it's just all over the place. And
- 23:17Speaker 2: that actually is a little bit unnerving. So I think,
- 23:19Speaker 2: if anything, you should err on the side of caution,
- 23:22Speaker 2: which is I think what they're doing with the geological
- 23:24Speaker 2: repositories essentially is saying, put it as deep in the
- 23:28Speaker 2: earth as we possibly can, cover it up, walk away,
- 23:31Speaker 2: dusting your hands off, and pretend that it never even happened.
- 23:35Speaker 1: You know. What I bet they do is they say
- 23:38Speaker 1: how many years in the future. Do you think people
- 23:40Speaker 1: no longer care about their future family line? Yeah, that's
- 23:44Speaker 1: like one hundred thousand years. Yeah, that's great. Put that down.
- 23:47Speaker 2: I think it was one hundred and they just multiply
- 23:49Speaker 2: it to buy a thousand.
- 23:52Speaker 1: All right, So we should talk a little bit about
- 23:54Speaker 1: other kinds of nuclear waste. We were talking about the
- 23:57Speaker 1: high level waste again, the most problematic obviously, that is
- 24:01Speaker 1: just three percent, though of total nuclear waste, but contributes
- 24:06Speaker 1: ninety five percent of the total radio activity. More than
- 24:09Speaker 1: ninety percent of nuclear waste is low level, and this
- 24:13Speaker 1: is stuff that you know, it might be like the
- 24:16Speaker 1: protective clothes that you wre on site. It's got a
- 24:18Speaker 1: little radioactive dust on it, maybe some tools, maybe some
- 24:22Speaker 1: disposable materials. We have four locations in the US for
- 24:26Speaker 1: disposing of this low level stuff, one in South Carolina
- 24:30Speaker 1: and one in Washington State, one in Utah, and one
- 24:32Speaker 1: in Texas. And this stuff is not nearly as problematic.
- 24:36Speaker 1: It decays to safe levels in about again, who knows
- 24:39Speaker 1: for sure, but about twenty to thirty years. Well, I
- 24:41Speaker 1: guess in that case they can test it out at
- 24:43Speaker 1: this point. But that's treated almost like a landfill. It's
- 24:48Speaker 1: in case in concrete and covered with backfill.
- 24:51Speaker 2: Yeah, so yeah, we don't really have to worry too
- 24:54Speaker 2: much about low level waste, I think is the upshot
- 24:56Speaker 2: of that, right. Yeah, there's also transuranic waste, which has
- 25:00Speaker 2: incredibly long half lives, and these are often called defense
- 25:06Speaker 2: wastes because they are produced when we produce plutonium for
- 25:11Speaker 2: nuclear weapons. So sometimes plutonium grabs on to some of
- 25:15Speaker 2: the neutrons we've bombarded with and says, oh, let me
- 25:17Speaker 2: form some neptunium, which has a half life of two
- 25:20Speaker 2: point one four million years, or how about some americium
- 25:25Speaker 2: or plutonium two thirty nine itself has a half life
- 25:27Speaker 2: of greater than twenty four thousand years. So this stuff
- 25:30Speaker 2: is really it's really dangerous, But at the same time,
- 25:36Speaker 2: it also is really fissile, meaning it's ready to go.
- 25:39Speaker 2: It's hit me with some more neutrons and let's split
- 25:43Speaker 2: some more atoms so we can release some more energy.
- 25:45Speaker 2: So it's not necessarily a problem if we can figure
- 25:49Speaker 2: out what to do with it. It's just that we
- 25:53Speaker 2: haven't quite figured out how to use it yet, so
- 25:55Speaker 2: in the meantime it gets dropped into the waste isolation
- 25:59Speaker 2: pilot play and for longtime listeners of the podcast, we're
- 26:03Speaker 2: those curious enough to go through the back catalog, which
- 26:05Speaker 2: is really great. We did an episode on nuclear semiotics,
- 26:10Speaker 2: remember that, oh yeah, which is essentially trying to figure
- 26:13Speaker 2: out how to communicate with people ten thousand years in
- 26:15Speaker 2: the future that the waste isolation pilot plant is really
- 26:18Speaker 2: dangerous and to steer clear of it. That was probably
- 26:21Speaker 2: one of my favorite all time episodes.
- 26:23Speaker 1: Yeah, for sure, And you know, I'm glad you mentioned
- 26:25Speaker 1: that real quick, if we could just quickly say we
- 26:29Speaker 1: have many, many, many hundreds up to how many episodes
- 26:33Speaker 1: do we have a couple of thousand.
- 26:34Speaker 2: If you include the short stuff it's coming up on
- 26:37Speaker 2: like twenty three hundred.
- 26:38Speaker 1: I think, yeah, a lot of people like the reason
- 26:40Speaker 1: we mentioned this is we get emails every single day
- 26:43Speaker 1: where people like, you should do an episode on like
- 26:45Speaker 1: these five things, and we've done four of the five
- 26:47Speaker 1: of those, and so I think a lot of people
- 26:50Speaker 1: don't realize that. You know, we've been at this for
- 26:53Speaker 1: close to eighteen years, and so we have a vast
- 26:55Speaker 1: repository of things. And if you go to your podcast player,
- 27:00Speaker 1: I know on Apple podcasts, there's a little button you
- 27:02Speaker 1: can click at the bottom that says show all episodes. Yeah,
- 27:06Speaker 1: so go forth and listen. And in fact, we did
- 27:09Speaker 1: have one from twenty fourteen called can nuclear fusion Reactors
- 27:12Speaker 1: Save the World?
- 27:13Speaker 2: Yeah, so that was a good one too. I love
- 27:16Speaker 2: that one. That's different than this.
- 27:17Speaker 1: Yeah, that's different than this anyway. Lots of good back
- 27:21Speaker 1: catalog episodes, so we encourage you to seek them out.
- 27:24Speaker 1: A little googling can go a long way as well.
- 27:26Speaker 2: Yeah, and our webmaster, Brandon Reid, has put together a
- 27:29Speaker 2: world class search engine on our site, stuffyshould know dot com.
- 27:34Speaker 2: So if you type in any keyword of something you're
- 27:37Speaker 2: looking for, it's probably going to bring up bad episode,
- 27:40Speaker 2: maybe some other episodes that we cover that in, and
- 27:43Speaker 2: then you can listen to it right there on the
- 27:45Speaker 2: site too. So yeah, we do have a very deep
- 27:48Speaker 2: back catalog. It's almost geologic in its stretch.
- 27:52Speaker 1: How many Olympic pools deep? Is it?
- 27:55Speaker 2: At least ten to fifteen million? I would say.
- 27:57Speaker 1: Okay, so back to the waste isolated pilot plant in
- 28:00Speaker 1: New Mexico. Here they bury this transuranic Is that how
- 28:06Speaker 1: you said it?
- 28:06Speaker 2: Yeah?
- 28:07Speaker 1: Okay inside a salt layer. That's a couple of thousand
- 28:10Speaker 1: feet below the surface, and salt doesn't have any maybe
- 28:16Speaker 1: a little bit, but basically no groundwater flow. And you know,
- 28:20Speaker 1: water's your enemy as far as a corrosive agent with
- 28:22Speaker 1: all this stuff. But the salt is going to form
- 28:25Speaker 1: a seal, just sort of like that clay did around
- 28:27Speaker 1: those canisters. And that's what we do with that stuff.
- 28:30Speaker 1: And I mentioned, you know, decommissioning entire nuclear power plants
- 28:35Speaker 1: and reactors. That's something that you have to do because,
- 28:37Speaker 1: like I said, these things, you can't just keep tightening
- 28:40Speaker 1: the bolts on these and expect it to keep running.
- 28:43Speaker 1: I think, in fact, in the United States, sixty years
- 28:47Speaker 1: is like the maximum limit before they say shut this
- 28:49Speaker 1: thing down.
- 28:50Speaker 2: Yeah, And strangely I did not realize this, but most
- 28:54Speaker 2: of the contaminated stuff is low level waste, like you know,
- 28:58Speaker 2: hazard suits and stuff like that. And even the concrete
- 29:01Speaker 2: that the whole power plan is made from. I saw
- 29:04Speaker 2: that only about one percent of it is radioactive. The
- 29:07Speaker 2: rest can just be treated as construction waste. Essentially. I
- 29:11Speaker 2: saw a proposal saying like, don't do that, like reuse
- 29:14Speaker 2: this stuff as the concrete, like recycle it as the
- 29:17Speaker 2: concrete that seals in the dry casks and stuff like that.
- 29:20Speaker 2: So there's actually there seems to be much more of
- 29:23Speaker 2: a push to recycle all this stuff, as we'll see.
- 29:27Speaker 2: But there's a whole process to decommissioning, and one of
- 29:32Speaker 2: the parts of this process is making sure all those
- 29:35Speaker 2: fuel assemblies spend or otherwise end up in the cooling
- 29:38Speaker 2: pool and then when it's their time to dry casks.
- 29:41Speaker 2: So what's interesting is a whole power plan will be
- 29:43Speaker 2: taken offline decommission. It's not producing power any longer, but
- 29:47Speaker 2: it still has all those fuel rods, and it's spent
- 29:50Speaker 2: fuel pool, it still has dry casks out back, and
- 29:53Speaker 2: there's still people watching over that stuff because we don't
- 29:56Speaker 2: have anywhere to put it. We're literally leaving them in
- 30:00Speaker 2: spent fuel pools after we turn the power off on
- 30:03Speaker 2: the nuclear power plants. That's what we're doing with our
- 30:06Speaker 2: nuclear waste right now.
- 30:08Speaker 1: Yeah, and there's that water in the pools. Like let's
- 30:11Speaker 1: say you finally get all of them out of the
- 30:13Speaker 1: pool and in dry cask, then you got a big
- 30:16Speaker 1: pool of I imagine, very soothing nuclear water that was
- 30:22Speaker 1: used as a coolant, and you got to do something
- 30:24Speaker 1: with that and what we do with it, And I
- 30:27Speaker 1: guess you know what's basically done with it all over
- 30:29Speaker 1: the world is it's cleaned and then dumped into a waterway,
- 30:34Speaker 1: an ocean or a river or a lake. And most
- 30:37Speaker 1: of these plants are by a body of water for
- 30:39Speaker 1: this reason. And you know, we'll talk a little bit
- 30:43Speaker 1: about how this is done, the two main processes. But
- 30:46Speaker 1: I'm not like a conspiracy guy or hugely cynical, but
- 30:50Speaker 1: I just don't see how that water can ever be
- 30:52Speaker 1: good enough to dump into an ocean or a lake.
- 30:55Speaker 2: The only thing I've seen is dilution that full first
- 30:58Speaker 2: of all, so they filter out as much of the
- 31:00Speaker 2: radio nuclides as possible, right, Yeah, and there's whole processes
- 31:03Speaker 2: for separating those things out from the water, but there's
- 31:06Speaker 2: still some left. But their premise is that they're adding
- 31:10Speaker 2: so much fresh water to it. Yeah, before they dump
- 31:13Speaker 2: it into the ocean. It's fine. But I think that's
- 31:16Speaker 2: a very valid point. Like we're talking about nuclear science here,
- 31:22Speaker 2: and this is how far behind the environmental part of
- 31:26Speaker 2: nuclear science is lagging that we're just like, it's fine,
- 31:31Speaker 2: forget about it, We're just gonna dump it in the
- 31:33Speaker 2: ocean and yes, it's not so bad that they're not
- 31:36Speaker 2: treating it first and diluting it first, but it's still
- 31:39Speaker 2: it's like, really, that's what we can do. That's the
- 31:41Speaker 2: best we can do right now. And the answer is.
- 31:43Speaker 1: Yes, yeah, I mean that's Uh, if I don't mention
- 31:47Speaker 1: the three eyed fish on the Simpsons, we're gonna get emails.
- 31:50Speaker 1: I guess that we have to mention that, right you bet?
- 31:53Speaker 2: Man.
- 31:53Speaker 1: Did that fish have a named blinky?
- 31:56Speaker 2: I think, Oh really, I'm pretty sure.
- 31:59Speaker 1: Didn't it blink? In sequence? Yeah, like pink pink pink. Yeah,
- 32:04Speaker 1: that's very funny.
- 32:05Speaker 2: That was a pretty cool fish.
- 32:07Speaker 1: Uh yeah. So that's that's what happens to the water.
- 32:09Speaker 1: So maybe we should take our second break here and
- 32:11Speaker 1: talk about a bit of a brighter future with ideas
- 32:15Speaker 1: for recycling and more. Right after this, goods.
- 32:26Speaker 2: Up with jaw shoe on chow out stuff fish. Okay, check.
- 32:37Speaker 2: So I think I said that there's kind of a
- 32:40Speaker 2: new spirit of recycling that's kind of starting to sweep
- 32:44Speaker 2: the nuclear industry as far as environmental aspects are concerned.
- 32:48Speaker 1: Right, yeah, like you can recycle this stuff.
- 32:50Speaker 2: Yeah, Because there's a couple of things. One is where
- 32:54Speaker 2: when a nuclear fuel rod is spent, it still has
- 32:58Speaker 2: like like a lot of energy left in it. It's
- 33:03Speaker 2: just like you said, not enough energy to power an
- 33:07Speaker 2: old school nuclear reactor. So one solution is to develop
- 33:11Speaker 2: more advanced reactors that can use those same things as fuel.
- 33:17Speaker 2: They're just much more sensitive. Another thing is to take
- 33:21Speaker 2: those and recycle them, like extract the usable stuff out
- 33:25Speaker 2: of it, form new pellets and just start the cycle again.
- 33:29Speaker 2: And you're doing a couple of cool things here. One,
- 33:32Speaker 2: you're taking out the most dangerous part of the radioactive
- 33:37Speaker 2: nuclear waste and leaving behind far less dangerous waste that
- 33:42Speaker 2: you still have to figure out what to do with,
- 33:43Speaker 2: but it's not nearly as bad as the stuff that
- 33:45Speaker 2: you took out of it. And then you're also reusing
- 33:48Speaker 2: power that otherwise under the current plans of just bury
- 33:52Speaker 2: and forget it, you're burying all of that energy. There's
- 33:56Speaker 2: so much energy. There's a startup called oakloh and they
- 34:00Speaker 2: they estimate that the unused spent fuel that we're talking
- 34:06Speaker 2: about just burying thousands of feet under the ground could
- 34:10Speaker 2: power the United States, the entire United States for the
- 34:13Speaker 2: next one hundred and fifty years, just with the spent
- 34:16Speaker 2: nuclear fuel we have right now, and the idea is
- 34:19Speaker 2: to just bury and forget about it. And it's so
- 34:21Speaker 2: stupid that it actually could be considered a lucky break
- 34:26Speaker 2: that Yucca Mountain didn't work out back in twenty ten,
- 34:30Speaker 2: and it's in limbo because it bought time for people
- 34:33Speaker 2: to come up with other ideas rather than just bury
- 34:36Speaker 2: the stuff that's just such a total waste.
- 34:39Speaker 1: Yeah, Oaklo says they can recycle and reuse ninety four
- 34:42Speaker 1: percent of uranium in those spent fuel assemblies, and they're
- 34:45Speaker 1: just one of ten companies. I think they got a
- 34:48Speaker 1: license from the Department of Energy to build a recycling
- 34:52Speaker 1: plant in Oakridge, Tennessee. Shout out to the boys. Sure,
- 34:57Speaker 1: and they're one of ten companies that the Department of
- 34:59Speaker 1: en selected as part of their reactor Pilot program to
- 35:04Speaker 1: build these new reactors that can be powered by recycled uranium.
- 35:08Speaker 1: So that seems like a great way forward. One of
- 35:13Speaker 1: the concerns here is that you know there is a
- 35:16Speaker 1: security risk even though like that stuff is again, like
- 35:20Speaker 1: you said, spent, if you can recycle it to use again,
- 35:24Speaker 1: even in that small quantity of unspentness, you could also
- 35:28Speaker 1: make a dirty bomb. Or something for that, so it
- 35:32Speaker 1: needs to be pretty pretty locked down.
- 35:34Speaker 2: And the same fear, except even worse, is associated with
- 35:38Speaker 2: extracting plutonium from spent nuclear fuel to use that because
- 35:45Speaker 2: that is the core of a nuclear weapon, and that's
- 35:48Speaker 2: the kind of thing that a foreign country that doesn't
- 35:51Speaker 2: have a nuclear program but really wants one has the
- 35:54Speaker 2: resources to steal from some startup that is refining and
- 35:59Speaker 2: extracting their facility in Tennessee. That's a huge that's actually,
- 36:04Speaker 2: from what I can tell, the number one obstacle to
- 36:08Speaker 2: recycling nuclear waste that security concern.
- 36:13Speaker 1: Yeah, I mean they could fix that though.
- 36:15Speaker 2: I guess. I mean, we keep our nuclear stockpile safe,
- 36:19Speaker 2: or we have for this long, so why can't we
- 36:21Speaker 2: apply some of that same security to these recycling plants.
- 36:25Speaker 2: I don't understand. It just seems like, a yeah, that's
- 36:28Speaker 2: a huge risk, but it's not something we can't figure out,
- 36:31Speaker 2: you know.
- 36:31Speaker 1: Well, I feel like it probably have to be in
- 36:34Speaker 1: working in concert with the government and not just saying
- 36:37Speaker 1: like all right, Oaklow, you got your security team. I
- 36:39Speaker 1: see those people with the black eyes odds on, It's
- 36:44Speaker 1: all good.
- 36:45Speaker 2: Yeah. So one of the other things we should say,
- 36:47Speaker 2: I think that people are kind of wary about is
- 36:49Speaker 2: that these startups that are talking about new ideas for
- 36:53Speaker 2: nuclear power are typically doing it to get government buy
- 36:58Speaker 2: in to help fund them to build nuclear plants to
- 37:03Speaker 2: power their AI. So these are like like I think
- 37:06Speaker 2: Oaklo is backed by Sam Altman from Open AI. Essentially
- 37:11Speaker 2: humanity would benefit as a side effect from new advanced
- 37:15Speaker 2: designs for producing nuclear power with less waste. That'd be great,
- 37:19Speaker 2: But the intent, the immediate intent by the people who
- 37:22Speaker 2: are doing this is typically to produce cheaper power to
- 37:26Speaker 2: power their increasingly massive artificial intelligences. That's I think makes
- 37:31Speaker 2: some people wary, including me.
- 37:34Speaker 1: Yeah, I mean combining those businesses is a little it's
- 37:40Speaker 1: a little worrisome.
- 37:41Speaker 2: It is. And I can't let an opportunity pass to
- 37:43Speaker 2: shout out. If anyone builds it, everyone dies. By Eliezer
- 37:47Speaker 2: Yukowski and Nate Sores, it's so good where they just
- 37:51Speaker 2: lay out a very straightforward example of how AI could
- 37:56Speaker 2: just get out of control and how we humans would
- 37:58Speaker 2: be in big trouble. And yet it's it's not like
- 38:00Speaker 2: they're AI haters. They're just basically saying, like, we're going
- 38:03Speaker 2: at this at such a terrible pace so recklessly that
- 38:07Speaker 2: we need to put the brakes on globally and figure
- 38:10Speaker 2: out how to do it safely and then do it
- 38:12Speaker 2: and then humanity can benefit from it. So they're not
- 38:15Speaker 2: like lightites or anything like that, and they know what
- 38:16Speaker 2: they're talking about. It's just a good book.
- 38:19Speaker 1: Yeah, well, you know, with things how things are going
- 38:22Speaker 1: these days, I could use little pick me up, so
- 38:24Speaker 1: maybe a little light reading. Maybe I'll start that again.
- 38:27Speaker 2: It is like you could read it in a day, man.
- 38:30Speaker 1: A very depressing day.
- 38:32Speaker 2: It's good though. It's really interesting too because it's also
- 38:34Speaker 2: a peek inside the current state of the AI industry too,
- 38:39Speaker 2: Like they're insiders, they know what's going on all right.
- 38:42Speaker 1: So I mentioned earlier these deep geological repositories that they've
- 38:46Speaker 1: almost finished in Finland, Like those aren't the best idea
- 38:49Speaker 1: because who knows what's going to happen long term here
- 38:51Speaker 1: on planet Earth. But they are, you know, extracting the
- 38:56Speaker 1: most highly radioactive parts of this waste from everything else else.
- 39:00Speaker 1: Seems like that's headed toward a pretty a pretty good solution.
- 39:06Speaker 1: So they don't know quite what to do with it afterward.
- 39:09Speaker 1: But one way of doing it is something called transmutation, right.
- 39:14Speaker 2: Yeah, I thought this was kind of genius. So essentially
- 39:16Speaker 2: it's taking the extracted most radioactive parts of nuclear waste
- 39:21Speaker 2: and tossing it into a particle accelerator and bombarding it
- 39:25Speaker 2: with neutrons, and by doing so you actually either you
- 39:29Speaker 2: either change them a neutron knocks them proton or some
- 39:34Speaker 2: something off of one of these off of each of
- 39:37Speaker 2: these atoms and converts it into something far less radioactive
- 39:40Speaker 2: that might decay much more quickly, or they grab onto
- 39:45Speaker 2: a neutron and they transform in that way and become
- 39:48Speaker 2: something that might be much more stable that isn't radioactive
- 39:51Speaker 2: at all. And so you're taking the really radioactive stuff
- 39:55Speaker 2: and you're degrading it really quickly in a particle accelerator,
- 39:58Speaker 2: and if you do it correct Flea, I guess in principle,
- 40:02Speaker 2: I think all of this is theoretical right now, Yeah,
- 40:04Speaker 2: you could actually produce energy while you're doing this, So
- 40:08Speaker 2: while you're getting rid of waste, you could be producing
- 40:11Speaker 2: energy from the bombardment bombardment.
- 40:14Speaker 1: I love this thought process. Another one that holds a
- 40:17Speaker 1: lot of promise is actually glass and ceramics. Glass and
- 40:21Speaker 1: ceramics can both trap those radio nuclides that you were
- 40:25Speaker 1: talking about, and for like a long period of time,
- 40:29Speaker 1: and you know, the idea is that you store this
- 40:32Speaker 1: stuff in these like like glass logs or ceramic logs. Basically,
- 40:38Speaker 1: glass doesn't degrade very easily, forms a very tight bond
- 40:43Speaker 1: that's kind of like a force field that says nothing's
- 40:45Speaker 1: getting in or getting out. It's a process called vitrification.
- 40:50Speaker 1: But it's not just regular old glass. It's like, you know,
- 40:54Speaker 1: sort of heavy duty nuclear containing glass.
- 40:57Speaker 2: Yeah, and what's cool about it is the glass law
- 41:00Speaker 2: uggs don't act as like container that you put waste in.
- 41:03Speaker 2: You melt the glass, making minerals and the waste together
- 41:07Speaker 2: and it forms the glass log together, so like you're
- 41:10Speaker 2: actually trapping the radioactive particles in glass, not inside glass
- 41:15Speaker 2: as part of glass. It's really genius.
- 41:18Speaker 1: Yeah, yeah, I thought that was clear. But yeah, it's
- 41:20Speaker 1: thanks for clearing that up.
- 41:21Speaker 2: You're welcome. And you can also do the same thing
- 41:23Speaker 2: with ceramics too, apparently.
- 41:26Speaker 1: Yeah, ceramics work just as good. We can also re
- 41:30Speaker 1: recycle the fistle material we're trying to you know, the
- 41:35Speaker 1: gold there is to recover uranium and plutonium, the main
- 41:38Speaker 1: materials main fissle materials and again separating out the most
- 41:43Speaker 1: radioactive parts of the waste product. Is what you're doing,
- 41:46Speaker 1: is you're trying just to make it all less bad,
- 41:51Speaker 1: less radioactive for.
- 41:52Speaker 2: Sure, and then hopefully doing something with it, like turning
- 41:55Speaker 2: it back into pellets like I saw to make a
- 41:58Speaker 2: mixed uranium plutonium oxide MOX fuel, you can use eight
- 42:04Speaker 2: old pellets to create one new one, so it actually
- 42:06Speaker 2: is pretty efficient, and you can keep doing that over
- 42:09Speaker 2: and over again until essentially you just don't have enough
- 42:13Speaker 2: left to actually produce any energy. And one of the
- 42:17Speaker 2: other points that I saw, Chuck, is that even if
- 42:20Speaker 2: we can't figure out how to reuse the fuel that
- 42:24Speaker 2: we've isolated and extracted from the spent nuclear fuel waste,
- 42:30Speaker 2: just being able to do that would reduce it by
- 42:32Speaker 2: so much that it would take a huge amount of
- 42:35Speaker 2: our problem for figuring out what to do with the
- 42:37Speaker 2: waste off of the table. So like, if that stuff
- 42:40Speaker 2: is one percent of all nuclear waste and the United
- 42:43Speaker 2: States has ninety thousand tons of it, that would drop
- 42:46Speaker 2: it down to just nine hundred tons of really problematic
- 42:49Speaker 2: stuff that we had to figure out how to get
- 42:51Speaker 2: rid of ninety thousand so there's I mean, aside from
- 42:55Speaker 2: that security risk thing, there's really no reason not to
- 42:58Speaker 2: process nuclear ways to get the high energy stuff out
- 43:02Speaker 2: of there for one reason or another.
- 43:04Speaker 1: Yeah, for sure, I think that's it.
- 43:06Speaker 2: Man.
- 43:07Speaker 1: Yeah, go forth and recycle your uranium pellets in your home.
- 43:13Speaker 2: That's right, Chuck. And since Chuck talked about recycling uranium pellets,
- 43:17Speaker 2: obviously it's time for listener man.
- 43:21Speaker 1: This is from Kelly Gizmondi. Hey, guys, I'm a lawyer
- 43:26Speaker 1: in Louisiana, started listening to Stuff You Should a few
- 43:28Speaker 1: years ago and currently working my way through the back
- 43:30Speaker 1: log and enjoying every minute. Just got done listening to
- 43:34Speaker 1: your solitary confinement episode and was thrilled to hear you
- 43:36Speaker 1: talk about the Angola Three. I have represented folks from
- 43:39Speaker 1: Angola and one of the most interesting stories from Angola
- 43:42Speaker 1: that was recently published by Calvin Duncan, who was wrongfully convicted.
- 43:46Speaker 1: By the way, It's called The Jailhouse Lawyer, which is
- 43:49Speaker 1: a deep dive into what life is like for inmate counsel.
- 43:54Speaker 1: Inmate counsel or a group of incarcerated folks who learn
- 43:56Speaker 1: and then teach others the law, draft motions and legal
- 44:00Speaker 1: islings for others who are incarcerated and help advocate for
- 44:03Speaker 1: those incarcerated as a whole. This is an essential service
- 44:06Speaker 1: for the incarcerated community because there is no right to
- 44:09Speaker 1: precuncel for post conviction relief, and many people who have
- 44:12Speaker 1: been convicted of crimes cannot afford legal fees for post
- 44:15Speaker 1: conviction relief. Man Essentially, if you are poor and have
- 44:19Speaker 1: been wrongfully convicted of a crime, or if there's another
- 44:22Speaker 1: legal issue with your conviction, often the only way to
- 44:25Speaker 1: get legal help is to work with inmate counsel. They're
- 44:27Speaker 1: incredibly effective and have helped get thousands of incarcerated folks
- 44:31Speaker 1: across Louisiana home to their communities. Would love to hear
- 44:34Speaker 1: an episode on this. Thanks for all you do for
- 44:36Speaker 1: my brain. That is sincerely from Kelly GISMONDI and Kelly,
- 44:41Speaker 1: that may be a good short stuff. There's not a
- 44:43Speaker 1: ton out there, but I bet you we could find
- 44:47Speaker 1: fifteen minutes easy.
- 44:48Speaker 2: Yeah, let's do it, man, because that is definitely as
- 44:51Speaker 2: far as I'm concerned, and overlooked issue and the justice
- 44:54Speaker 2: system for sure.
- 44:56Speaker 1: Yep.
- 44:57Speaker 2: Well, God bless you Kelly for what you're doing, your
- 44:59Speaker 2: work helping people who may have gotten screwed over by
- 45:03Speaker 2: the system. And if you want to be like Kelly
- 45:06Speaker 2: and email us to let us know what you're doing
- 45:08Speaker 2: to help your fellow person we want to hear about that.
