 | This post is about nuclear power. It is long. If you want to debate, that is welcome but please read this post first. It's likely I will have addressed your concern in it. There will be no tl;dr. submitted by Vaudane to ExtinctionRebellion [link] [comments] I've seen a fair few posts on here, and other "green" sites doing their best to discredit and undermine the science of nuclear power in lieu of glorified pipe dreams. That the world can go 100% "renewable" (with plenty of caveats tacked on the end of course, half of them unfeasible). There are 4 main "arguments" against nuclear power. Danger, waste + storage, cost, and fuel availability. This post is to hopefully illustrate why all are red herrings designed to sew FUD and in actual fact keep us tied to a hydrocarbon-based grid. DangerThis is a three-prong argument. The first usually invokes events such as Chernobyl, Fukushima, TMI, and other lesser incidents; the second invokes radiation safety; and the third mentions terrorism.Starting with nuclear events, of these three I mentioned---only one is actually at all relevant and that's TMI. But mentioning it in terms of safety is the equivalent of comparing a ford model-T to a modern family saloon. Additionally, it led to the raft of safety measures we now have thus preventing it from ever happening again. Chernobyl is a total red herring. While it wasn't a good event, it's pretty much the only event in nuclear power history that has led to any "significant" casualties, with the official death toll being 60 and numbers in the region of 6-20k cited from extended exposure. Whilst high for a single event, this makes up the vast majority of all nuclear incidents and in terms of death/TWh produced, still results in nuclear being the safest of all power sources. Plus, the RMBK reactor used on site wasn't designed for producing power, but for plutonium for nuclear bombs. As such, it was made deliberately unsafe so they could pop it open quickly to get the Pu out. It was this deliberate design choice that caused the failure. Obviously, this is not present in power-based reactors. It's also likely that the deaths are overestimated in this event due to the employment of the linear no-threshold model, which has repeatedly been shown to be flawed, and a hormetic model should instead be employed. This even gets ramped up to 11 in some countries that have radiation "spas" where you sit in a radon-filled basement in a bath-robe. https://en.wikipedia.org/wiki/Linear_no-threshold_model https://pubmed.ncbi.nlm.nih.gov/24298226/ And Fukushima? Yes it wasn't ideal, but literally nothing has come of it. No increased cancers. No deaths. No change in the background radiation level. Those maps bandied about showing the "flow into the ocean"? Garbage designed to spread FUD. The site fundamentally failed because a tsunami was higher than the seawall and drowned the diesel generators that were below sea-level. If the reactor hadn't shut down, it's likely it wouldn't have failed at all. Fukushima is less anti-nuclear and more anti-diesel generator. https://www.snopes.com/fact-check/fukushima-emergency/ https://world-nuclear.org/information-library/safety-and-security/safety-of-plants/fukushima-daiichi-accident.aspx The clean-up will cost money yes, but see the section later about why that's actually a good thing. Other events such as the Windscale fire were also caused by plutonium production. Now lets compare those deaths with another singular event: a damn bursting in China. 230k dead. More than 10x all the nuclear incidents ever yet I don't hear many here complaining about hydro-power. https://www.ozy.com/true-and-stories/230000-died-in-a-dam-collapse-that-china-kept-secret-for-years/91699/ In fact, comparing all the methods of power generation as deaths/terawatt-hour produced, nuclear is safest by about an order of magnitude (in other words, 10x more power can be produced for each person killed by that method of generation). How many people do you want to die to keep your lights on? https://www.nextbigfuture.com/2011/03/deaths-per-twh-by-energy-source.html The second of these prongs is fear of radiation. While I briefly touched on it when discussing Chernobyl, the fear runs much deeper. The main problem here is lack of scientific education, and an overzealous media. The thing about radiation is we are very good at detecting it, even at very low levels, and some units need to use very large numbers, such as atomic decays/second (Bq). Thing is, there are a lot of atoms in a small volume of anything. Avogadro's constant tells us that there are 6.022x1023 atoms in one mole of the substance. And one mole is the atomic number of the element in grams. So 92g of Uranium has 602,200,000,000,000,000,000,000 atoms (approx). And with the density of U being ~19.1g/cm3, that's 5 cubic centimetres of uranium. Or a double shot in a bar. This sort of numbering has led to the tongue in cheek unit "banana equivalent dose". https://en.wikipedia.org/wiki/Banana_equivalent_dose Yes, that is the radiation dose you will get from eating a banana. In continuation, people will talk about waste being so hazardous, but without really understanding the numbers. So what are those numbers? Well, the granite worktop in your kitchen would be classed as nuclear waste under current legislation, thanks to radon in it. Terrorism is another danger often cited. And this may even be a valid one, if there had ever been a terrorist attack on any nuclear plant across the world in the history of the human race. They're also designed to withstand a direct impact from a train or a 747, so a 9/11 attack isn't a concern. On a related vein, many conflate nuclear power with nuclear weaponry. These two implementations are about as different as can be, with the only commonality is that they both use a radioactive source. It would be like decrying a coal plant because C4 explodes as both are carbon based. Nuclear weaponry and nuclear power are fundamentally different technologies and cannot be conflated. Waste/StoragePeople don't think of granite worktops or gloves or aprons being "nuclear waste" though, they think of leaking soft steel barrels full of green liquid seeping out into waterways and turning us all into three-armed monstrosities with cancers out the wazoo. Except, none of that is true. Including the fact it's waste at all. So from now on I will call them used fuel rods, as that is what they are, The way fuel rods are disposed of is in a water bath for heat control of any short-lived elements to decay away, and then they are stored in "dry cask storage", or large concrete barrels on the reactor site.https://en.wikipedia.org/wiki/Dry_cask_storage "But these barrels are dangerous right? You will die if you get near them?" Well, yes. But only because the armed guards on site will shoot you as you run towards them. If you had proper clearance, you could sit and have lunch leaning up against one with negligible radiation dose. "But these drums are piling up with nowhere to store them, It's a catastrophe". Well... also no. As you may remember the numbers from the previous section, volumes are small. If you were to take the entire US stockpile of used fuel rods and group them together, you'd have a mass of 70k metric tonnes. Sounds a lot right? But remember the density of uranium, that gives a volume of about 3665 m3. For comparison, single football stadium (I've pulled up Samara Arena in Russia for convenience), it has a volume of 503,480 m3. So the entire volume of used nuclear fuel in the US wouldn't even fill a football stadium, and in fact wouldn't even come close. I'd say we've got room to breathe there. "But it lives for billions of years right and is super radioactive right?" Well, again, not quite. Think of anything, the hotter it burns, the shorter it lives. Same with nuclear fuel. The high-activity nuclides in the used fuel rods decay in days-weeks. What's left is inert filler with fresh uranium mixed through. In fact, after it's removed from the reactor, it's still about 95% fresh uranium. Which has a half life of billions of years, but consequently is also low activity. You could hold reactor rods in your hand and be fine. And in fact this is how they are installed into a reactor in the first place. Notice no lead aprons, no serious PPE. Just gloves and goggles. Fuel Rod Assembly: U.S. Department of Energy Office of Nuclear Energy And yet in the US that's buried underground. Why? Blame President Carter. https://en.wikipedia.org/wiki/Nuclear_reprocessing In fact, that is the only main problem with storage of used fuel rods. The US gets a disproportionate amount of air-time across the world, and it also cannot reprocess its used fuel. It'd be like a car in which most of the petrol you put in trickled out the exhaust again. You'd either improve the design, or put it through again. And that's the purpose of either recycling the fuel rods, or using what is known as a breeder reactor. And in fact these breeder reactors are grid-proven and it's literally just lack of political will preventing them being rolled out. https://en.wikipedia.org/wiki/BN-800_reactor If the US was the recycle all the fuel it had in storage, it wouldn't need to mine any more for the next century or so. Yes, century. Fuel Availability"But it'll all run out eventually? In fact, a lot of estimates put it at only ~200 years availability? Why bother when the sun and wind are essentially limitless?"Again, not quite. This figure comes from single-pass fuel use then storage. As I've just shown, that's incredibly inefficient and frankly a stupid way to handle it. In fact, if you combine breeder reactors, and fuel reprocessing, we have enough fissile fuel to keep our reactors happy for the next few hundred thousand years. https://www.scientificamerican.com/article/how-long-will-global-uranium-deposits-last/ Cost"But it's really expensive to build nuclear plants and takes too long."It is expensive to build the nuclear plants yes, but the time taken to build them is largely based in legislation which itself is based in flawed science (as I mentioned earlier with the LNT statements). But when investigate it as a levelised cost of energy (LCOE), nuclear is pretty much front of the queue. https://world-nuclear.org/information-library/economic-aspects/economics-of-nuclear-power.aspx Plus, I'm going to take a little detour out of science here and start talking about economics. Things being expensive for a government is not the same as things being expensive for a person/business. The fundamental difference is that the latter is a user of currency, whilst the former is the issuer of currency. A common way of thinking is the out-dated gold standard, in which currency is finite and tied to gold/tax receipts/stocks/bonds. This, and consequential statements such as "we are generating debt our children must pay" hasn't been true since 1971. The government, being able to issue its own currency can never go bankrupt as it can always pay its debts. This also does not lead to inflation as it used to. If this has you scratching your head in disbelief, that's understandable. I suggest the book "The Deficit Myth" by Prof. Stephanie Kelton. Additionally, she does a really good seminar on it here and is definitely worth a watch: https://www.youtube.com/watch?v=Q1SMjeuyF-Y So fundamentally, if the government wish to build nuclear, they have both means and motive to do so, with no detriment to the economy (unless you count people in work being a detriment). A few conspicuous sites are also mentioned in nuclear costs. These are typically Hanford in the US, and Sellafield in the UK. Both of these sites are scheduled to take decades to clean up, and cost hundreds of billions of $/£ to do so. This sounds ominous, but it isn't. Both of these sites were built in the 40s/50s as research sites and plutonium production facilities. Neither of these are actually relevant to modern power production and are simply a legacy from a time we didn't understand nuclear materials. When discussing US decommissioning costs, Hanford makes up 80% of this budget in the US, and Sellafield making up 75% in the UK. https://en.wikipedia.org/wiki/Hanford_Site https://www.nbcnews.com/news/all/cost-taxpayers-clean-nuclear-waste-jumps-100-billion-year-n963586 https://en.wikipedia.org/wiki/Sellafield https://www.gov.uk/government/publications/nuclear-provision-explaining-the-cost-of-cleaning-up-britains-nuclear-legacy/nuclear-provision-explaining-the-cost-of-cleaning-up-britains-nuclear-legacy DiscussionSo why am I so bothered? Why bother making this post at all? I am a scientist and it bothers me to see disinformation and anti-science get spread so freely. There is also an extremely bad-faith argument from a lot of people in this regard, as they do not discuss the waste generated in the production of renewables, nor the full LCOE and instead cherry pick good days and state it as an average. This disingenuity has led to some of the most expensive power in the US for Californians, and Germany needing to fire its coal stations back up as well as import power from nuclear powered France. Furthermore, the American Association for the Advancement of Science (AAAS) performed an interesting study, in which it collates the opinions of those educated in science versus the general public. It can be seen that when formally trained in science, the approval rating nuclear is much higher. Surely we want our path to saving the planet rooted in science instead of hubris?https://www.pewresearch.org/science/2015/07/23/an-elaboration-of-aaas-scientists-views/ Also as I showed with the burst-dam, there are statements made about nuclear that are not made about renewables. So if I repeat the process, the waste produced for solar and wind is not discussed often enough. Both wind and solar produce huge volumes of toxic and radioactive waste. But as they are not as similarly constrained as the nuclear industry, this is both unaccounted, and just drained to the environment. https://www.cfact.org/2019/09/15/the-solar-panel-toxic-waste-problem/ https://www.instituteforenergyresearch.org/renewable/wind/big-winds-dirty-little-secret-rare-earth-minerals/ https://e360.yale.edu/features/boom_in_mining_rare_earths_poses_mounting_toxic_risks Neither can the panels or blades be recycled so they go to landfill, to leech out toxic elements into the soil and groundwater. https://stopthesethings.com/2020/10/10/lingering-legacy-millions-of-toxic-solar-panels-that-cant-be-recycled-destined-for-landfills/ https://www.discovermagazine.com/environment/solar-panel-waste-the-dark-side-of-clean-energy https://www.bloomberg.com/news/features/2020-02-05/wind-turbine-blades-can-t-be-recycled-so-they-re-piling-up-in-landfills And if nuclear fuel availability is mentioned, then so should availability of the minerals required to produce renewables. Many of the minerals used have available supplies of less than a year, and as is in the name, they are rare to begin with. https://www.fpri.org/article/2020/10/chinas-monopoly-on-rare-earth-elements-and-why-we-should-care/ And to address a few points unique to renewables, the first is that by their method of operation, they harness a diffuse source. As such, they need to be big. Really big. Hundreds to thousands of hectares big. To produce an amount of power that could be generated by a reactor a fraction of the size. Now some people may find vast fields of solar panels or turbines beautiful, but I'd rather see vast woodlands, prairies, swamplands. I'd rather see our land returned to nature to actually capture some of the carbon that's ready to drive our extinction. It would also have the additional benefit that it would actually give back to the environment, and allow the bugs, birds, reptiles, critters, grazers, and hunters to thrive again. They don't thrive under windmills or solar panels. https://www.strata.org/footprints/ https://www.heraldscotland.com/news/18270734.14m-trees-cut-scotland-make-way-wind-farms/ https://theconversation.com/wind-farms-built-on-carbon-rich-peat-bogs-lose-their-ability-to-fight-climate-change-143551 "But it's cheap!" Exactly, and that's why renewables still have a place as is shown by the "energy pyramid" attached. Every rooftop should be lined with solar panels. Domestic windmills should be used to feed back into the grid. The land is already used, so make the most of it. But don't destroy nature to build renewables, as this is often exactly what happens. The Energy Pyramid [Eric G. Meyer, Generation Atomic] There are further issues faced by renewables but not faced by nuclear. These are called "capacity factor" and "insertion factor", and neither permit for exponential power demands that we as a race face. The former is a simple one, wind doesn't blow all the time. Sun doesn't shine all the time. There needs to be a backup, that right now is natural gas. Super batteries will not fix this issue, and are actually more likely to render renewables obsolete as our demands will grow with our capacity. The second, insertion factor, relates to how once the "good spots" are taken, we must use less good spots, and as such need larger installations to make up for the shortfall in production. With nuclear, both of these do not apply. But why nuclear at all? Well, fundamentally, there is just so much uranium, and it is so energy dense, that it is silly to not use it. But when I talk about energy density compared to other fuels, it is hard to envision, so this wonderful presentation gives us more of a clue. https://youtu.be/tpUtrDvya1w So what does that energy density look like? Well, in a nuclear fuel assembly (shown earlier), there are hundreds of fuel pellets such as shown below. Each single one of those pellets are 7g of the ceramic uranium oxide, and can power a typical household for ~4 months. Fuel pellets in a fuel rod [nuclear.duke-energy.com] So why would you not want to use the cleanest, safest, arguably cheapest power source on earth? ConclusionThis post hopefully illustrates some of the common and unfortunately pervasive myths around nuclear power. And if for a moment we assume the problems are all real and genuine, we have less than 10 years to fix our planet before it starts trying, and likely succeeding, to kill us. This is not the time to be advocating anti-science or wanting to look like you care whilst doing nothing. If the waste issue was true, that gives us hundreds to thousands of years to find a problem. If the terrorism issue was true, we'd have high employment in the military to keep the sites safe. If the fuel availability issue was true, we could use it until we perfect fusion. But fundamentally, if you are about to be hit by an out-of-control bus, you do not worry about the grazed knee you get by jumping out the way.Edit 1: S/P Edit 2: Included the AAAS survey in the "Discussion" section.

In the cover story from the October 5, 2002 issue of the Pro Wrestling Torch Newsletter, it was revealed that contestant "Lisa" was removed from the show after what was referred to as a "psychotic breakdown." After being left at the house while the other contestants went out to dinner, she began throwing herself against the walls of the house, eventually breaking into the hidden MTV control room and working her way onto the roof. After being talked down by producers, she was committed to a hospital facility to receive psychiatric treatment. Her parents flew in from New Mexico to pick her up, but she physically attacked them, claiming she did not know them. She then escaped custody inside LAX, shutting down a wing of the airport until she was located. Again, she was hospitalized, but she was able to check herself out shortly after. She then contacted Tough Enough producers, claiming she was ready to return to the show. Producers informed her she had been removed from the competition due to her actions. The other contestants (and, subsequently, the audience) were initially told that Lisa simply decided wrestling "wasn't the right career for her." Lisa then reemerged in Louisville, Kentucky at the Ohio Valley Wrestling training center, claiming that trainer Al Snow and producer John "Big" Gaburick had sent her for additional training, both in the ring and to learn further about the structure of the developmental territory system. At a series of shows in California in September 2002, she managed to talk her way backstage and was even allowed to assist with the pyrotechnics for the wrestlers' entrances at a TV taping. One source claimed that she had a face-to-face conversation with Vince McMahon, who was apparently unaware of her status with the Tough Enough program. Soon after, her photograph was circulated to security personnel, and she was barred from any backstage areas.
