Nuke Retirements Could Lead To 4 Billion Metric Tons of Extra CO2 Emissions, Says IEA (arstechnica.com) 200

An anonymous reader quotes a report from Ars Technica: A report released today by the International Energy Agency (IEA) warns world leaders that -- without support for new nuclear power or lifetime extensions for existing nuclear power plants -- the world's climate goals are at risk. "The lack of further lifetime extensions of existing nuclear plants and new projects could result in an additional four billion tonnes of CO2 emissions," a press release from the IEA noted.

The report is the IEA's first report on nuclear power in two decades, and it paints a picture of low-carbon power being lost through attrition (due to the retirement of aging plants) or due to economics (extremely cheap natural gas as well as wind and solar undercutting more expensive nuclear power for years in some regions). Around the world, 452 nuclear reactors provided 2,700 terawatt-hours (TWh) of electricity in 2018. This makes nuclear a significant source of low-carbon energy on a global level. While 11.2 gigawatts (GW) of nuclear power were connected to the grid last year, all of the new capacity was located in China or Russia.
"Without additional nuclear, the clean energy transition becomes more difficult and more expensive -- requiring $1.6 trillion of additional investment in advanced economies over the next two decades," IEA says. "Critically, a major clean energy shortfall would emerge by 2040, calling on wind and solar PV to accelerate deployment even further to fill the gap."

    The immense negative exposure from the one-off nuclear accident is seen as a much greater threat than the slower polluting, carbon-releasing alternatives of burning coal and petroleum products for baseline electricity.

    It's fitting for our recently evolved goldfish-like attention span, I suppose.

      Wind and solar have been cheaper than coal for years, and that was with allowing coal to externalize its pollution costs. And your baseline FUD applies much moreso to nuclear power than to wind and solar, as your preferred expensive and dangerous method of...heating water goes down for weeks months or even years at a time for maintenance.

    Really, it's a question of money. As the article makes clear, nuclear is on life support not so much because of much-maligned activists and benighted citizens, but because like coal it can't compete in the market. Nuclear already benefits from a long history of billions of dollars in subsidies including tax credits and exemption from liability and the vague notion that the government will take up any extraordinary costs (which can be considerable -- the Fukushima cleanup decade is currently projected to last decades and cost over $200b...whatever the utility absorbs will surely come around to haunt tax/rate payers).

    At most article seems to srgue for extending the life of some reactors, presumably with subsidies ro competsate for competition from much cheaper solar, wind, and gas -- note that 2 out of 3 are already carbon friendly. So the choice is whather to shore up old tech or pour on the carbon-free gas (ha) for the next generation. Building new reactors is a non-starter: it can't be done fast enough and reactors have a long history f cost overruns and delays. This is all without mentioning that, yes, there are unique safety concerns with nuclear.

      Golly gee whiz! Why has nuclear power required government subsidies? Why has it not been able to compete in the market? It couldn't possibly be because the enormous costs of litigation, of fighting the ignorant superstitions of uneducated consumers whose biases are fueled by misguided tree-huggers, of struggling with the costs of storing nuclear waste because no state government wants to receive (I'm looking at you, Nevada!) and the federal government won't do what's right? No, couldn't be for any of those reasons. Nuclear can't compete because....well, you didn't give any reasons, so I thought I'd throw some into the discussion for consideration. Ignoring Lake Karachay and atomic weapon testing sites (which aren't really a product of nuclear energy), there have been, what? Three major nuclear accidents? Three Mile Island (no one was injured but the engineering was bad); Chernobyl (a tragedy caused by human error); and Fukushima (the result of cataclysmic natural disasters that could have been better anticipated, but there's no real way of knowing, because cataclysmic). There have been 76 deaths resulting from civilian nuclear facilities since 1957. Tell me, how many deaths are projected to result from global warming? And how much CO2 could have been avoided being injected into the atmosphere if nuclear power prevailed? Google is your friend and facts and education, information and understanding are the results.
      • Thank you for using sarcasm as a substitute for facts. But no, it has nothing to do with the cost of litigation (which you assert but conveniently fail to provide any evidence for). Fortunately, the US government provides data on the actual costs of constructing and operating [eia.gov] many different power sources. Look at table 3, and notice that wind and solar PV totally crush nuclear in every single region of the country. Nothing to do with lawsuits. This is just the cost of building nuclear plants, buying fu

      • I used to think this too, that nuclear was unprofitable just because we'd regulated it to death. But then I looked at other countries that are pretty lax about regulations, and they're building coal, not nuclear. The truth is that we've designed these things to be ridiculously expensive. I think we need a "nuclear SpaceX" to study the problem from a perspective of doing it cheaply, safely, and at scale. But it's very true that what we've got right now just isn't cost-effective, and it's not cost-effective

      I see you are already getting "overrated" mods, so I'd like to ask the nuke-fans something:

      What is your realistic, practical plan to make nuclear an attractive option again? What laws and rules would you change, what subsidies would you offer? Are you planning to fund long term research projects into new types of reactor?

      Tell us your plan.

        I would make it illegal for you and your ilk to file nuisance lawsuits any time someone tries to build a new nuclear plant. We would also ignore your input on every aspect of the design and placement of the plants.

        Yes, I'm serious.

        • by AmiMoJo ( 196126 )

          Tried that, the UK didn't have any NIMBY lawsuits over Hinkley C, and it's still by far the most expensive form of energy in the land.

          Next suggestion?

      • > practical plan to make nuclear an attractive option again?
        Right now let the industry build new reactors and issue combined construction and operation licenses.

        > laws and rules would you change
        No new laws are needed. Only rules that protect builders and operators from frivolous lawsuits which means follow existing law and let science, not emotion, dictate what we do.

          All this is happening. In the UK and China there are no frivolous lawsuits but the costs are still high. In the UK it's by far the most expensive form of electricity generation. They had to actually bribe the companies to take the operator licences.

          "If things go well" and "by 2027" for the first demonstrator to be operational, which presumably will take time to prove and develop into a commercial product, is no good. We need solutions sooner than that, and investors need certainty to be throwing billions of

            We don't have time to build a plant that can actually help with short building times and low costs that can compete against existing energy sources but we have time to destroy hundreds and thousands of miles of ecosystems hoping your solution scales and praying for a battery solution to come soon (tm)?

        What is your realistic, practical plan to make nuclear an attractive option again?

        Good and fair question. At the end, I want to turn the question around to you.

        First, let me echo what Applehu Akbar [slashdot.org] pointed out, which is stop making one-off nuclear plants and start using stable designs. I would add to that making smaller plants rather than large ones. Yes, the large ones scale better in theory, but in reality I think it increases the regulatory process disproportionately. I will add what Trailer Trash [slashdot.org] said in his reply as well.

          I'd start by looking at Greenpeace's plan to go 100% carbon neutral in a relatively short space of time. It's a big push but not unrealistic or unaffordable.

          Given the nature of politics though I'd probably look to take what I can from that and figure out what is deliverable.

          The core of it is wind, particularly off-shore wind, combined with a bit of storage and long distance DC transmission lines. When you have a vast amount of wind power over a large geographic area you actually don't need that much energy

          • by MobyDisk ( 75490 )

            I agree that wind is the best possibility at this point, definitely for the UK and Western Europe. I'm not so sure about North America or the rest of Europe. The middle of the USA is pretty far from off-shore wind, but maybe they can build their own wind farms.

            Side note: About a decade ago, I worked with a guy who was involved in a Canadian government research project where they looked into how much they could scale hydroelectric. They entertained the possibility of developing every possible source of hy

      Only billions? What subsidies do fossil fuels and natural gas receive?

      They have significant negative externalities which are not payed or rather, they are distributed and everybody pays. This not only includes released carbon dioxide but also radiation released by burning coal.

      And then there are the wars. How many trillions did the US pay for wars in the Middle East? How many nuclear reactors would that have built? How many cleanups would it have funded? So I will call your billions and raise you tril

    Cue all the slashdot commenters crying about climate change being a fairy tale, some typical APK-related nonsense, and some stuff for/against Trump. Oh, there's probably gonna be some railing against the /. editors too, of course. This is a den of retards.
    • How about replacing all the U.S. nuke plants with about 100 square miles of solar collectors and salt storage by having the government invest a few trillion dollars over a decade rather than war mongering? Is that retarded too?

      • Seems retarded to me because I don't think solar will scale. Obviously you disagree. I just hope you have some data or evidence to support the idea of scaling solar power to generate electricity for the entire planet. You do, right?

        • I was only speaking of USA though, it has plenty of land with abundant near constant sunshine

          Solar is scaling just fine in other countries. Makes sense, since it is possible to build more collectors and more storage that means it scales. There is no technological barrier to scaling it.

          • What country uses only solar power to generate its electricity? How do they store the electricity for use during the 20 hours a day when the sun isn't shining strongly enough or when it is cloudy or raining or snowing? You claim no tech barrier but you don't provide any examples or really anything at all to back that up. So you think New York City has abundant near constant sunshine and plenty of land?

            • I'm talking of solar collecting in U.S. desert with abundant sunshine and very little rain, more than 4 hours sunshine, and distributing with UHVDC lines which can go over 2000 miles.

      • Yes, that is retarded.

        Remember that article talking about all the species going extinct? Habitat loss. You propose we destroy countless ecosystems in the hopes that somehow your choice energy source will scale because of fear.

        If climate change is a problem to be solved then the only solution that will save the environment is nuclear. Everything else is window dressing and kicking the can down the road while destroying countless ecosystems.

        Add some science to your life. It's a good thing.

        • 100 square miles of desert is nothing. That 100 square mile size was picked for a very specific reason, it could supply all energy needs of the USA.

          no species that is significant will be extinct by doing this thing to a very tiny amount of land.

          we destroy 100 square miles of fertile densely specied land for suburbs every few years.

          Your stupid mentality is why we still have nuke plants and coal plants, you whine over real solution that will cost a tiny bit of land with some critters that won't be missed.

          • >miles of desert is nothing.
            Well since you say that ecosystem is nothing then who am I to argue. You must be a biologist. Did you know the largest contributor to species going extinct is habitat loss?

            >no species that is significant will be extinct by doing this thing to a very tiny amount of land
            Yes, "significant" species on a "tiny" amount of land. What's the point in saving the environment if you just going to destroy the environment.

  • Golly, imagine how much worse global warming would be if misguided and ignorant (not stupid, ignorant, there's a difference) environmental activists hadn't marginalized nuclear power? Imagine how much worse global warming would be if utilities could have used their profits for continuous research and engineering efforts to safely store nuclear waste? Imagine how much worse global warming would be if nuclear power generation technology wasn't frozen at 1970's levels? Oh, wait....
    • Imagine how much worse global warming would be if nuclear power generation technology wasn't frozen at 1970's levels? Oh, wait....

      It's amusing that you mention the 1970s, because PV solar panels could pay back their energy investment in less than seven years back then. Today, it's more like 3-5 depending on the technology. If we had spent the money since the 1970s building PV plants instead of wasting it on nuclear bullshit, how much PV generation capacity would we have today?

      • Today, it's more like 3-5 depending on the technology.
        Actually less than 2, and that includes the aluminium frames etc.

    seriously. They rant and rave that the planet will end in a dozen years or so if we do not immediately take drastic action to limit CO2 emissions. When told that such actions will cause millions of people to lose their jobs, they will often reply that the reductions are so important that a little collateral damage (people losing their jobs, homes, possibly marriages... devestated families) is "worth it".

    But then when you point out that nuke plants are vital to lowering ther carbon footprint, ooooooh noooooo

    The TFS, the press release, and the executive summary all unhelpfully talk about "4 billions tons" of CO2 being added, as if that was the end of story. This is the estimate of added CO2 from nuclear plant retirements to 2040, i.e., 20 years from now. This is heavily loaded toward the end of the period, when most of these projected plant retirements wi

    • Ah that's great

      In fact in 2040 the additional CO2 load would be about 1.2 billion tons of CO2 per year, forever assuming that the lost production was replaced by the best combined cycle natural gas plants (a likely prospect).

      Ah that's good to know, I tried to find the meaning of the numbers but didn't have the time to dig deep. Thanks.

  • Examining the carbon claims of Nuclear leads you to mining uranium. This is a highly carbon intensive endeavor which consumes as much of a third of the expected output of an AP-1000 to fuel it.

    The only reason the nuclear industry can make these carbon claims is because mining has been switched to in-situ acid leach mining which uses mega-liters of hydrogen-peroxide pumped into ore veins to extract the mineral. The by-product of this is hundreds of mega-liters of radioactive sulphuric acid that no one kno
