  Well, the radiation from Fukushima is expected to cause a few hundred cancer cases[1] even if nobody died from acute radiation poisoning. And there likely would have been acute radiation poisoning deaths if there hadn't been an evacuation, though probably far less than the 1600 deaths the evacuation caused. But even with all that the ~1 trillionkWhr Fukushima generated over it's lifetime puts it's death toll well below the Forbes numbers for even a US coal plant at 10,000. On the other hand, Sustainable Energy Without the Hot Air gives coal mortality at 350 to 60[2] after converting to the same units which is well below Fukushima's death toll.

    Yeah, you seem to be closer to the truth. I was assuming old knowledge from this summer, when Wikipedia was still saying that deaths won't be likely to increase: https://en.wikipedia.org/w/index.php?title=Fukushima_Daiichi_nuclear_disaster&oldid=724589571 https://en.wikipedia.org/w/index.php?title=Fukushima_Daiichi... >As of March 2012, no cases of radiation-related ailments had been reported. Experts cautioned that data was insufficient to allow conclusions on health impacts. Michiaki Kai, professor of radiation protection at Oita University of Nursing and Health Sciences, stated, "If the current radiation dose estimates are correct, (cancer-related deaths) likely won't increase." Still, it seems pretty ridiculous to worry about nuclear safety when the actual tsunami killed over 15,000 people and nobody seems to be up in arms why there weren't better safeguards against tsunamis.

    Now compare against an energy technology that is not Coal.

  > Funny you mention Fukushima, where zero people have died or gotten sick due to radiation, and experts say that the toll will probably stay at zero. This is the problem with the pro-nuclear approach to nuclear safety. Fukoshima was a massive safety failure. Something that was supposed to never happen did, the cooling failed, the reactors melted down, the containment breached and radioactive isotopes leaked and kept on leaking. At that point, it's not engineering that's protecting people, it's sheer luck and we don't even know the odds of the bet or the stake. We don't know how likely it was for an even bigger containment breach to occur, for things to have gone far worse, because the whole event was outside of the plan. Not only that, it was due to an issue that had already been pointed out by TEPCO's internal planning documents and ignored. (Then there's the huge economic costs of the radiation leaks.) Just ignoring this as a minor incident is inviting further failures which may not be so kind.
  • antris 10y ago
    I agree that it's a major failure, but doesn't that just mean that nuclear is even safer than people expect? Safety systems, backup safety systems, backup-backup safety systems can go down, and yet, the plant kills nobody. Even though the radiator had a meltdown, it was passively contained and the radiation didn't leak out in dangerous quantities. You mention that we don't know how likely a bigger containment was to occur, but I think there's barely a nugget of truth in that. The way the radioactive material was contained is very well understood. The safety systems worked, despite anything TEPCO did.
  • ageofwant 10y ago
    And yet not a single person died or are likely to die due to radiation poisoning. This begs the question, if all those fail-safes failed, do we really need them ?
    • sliverstorm 10y ago
      Well, it was certainly still a pain in the butt to clean up.

  > Costs The politicians are not "drafting rules to require more safety" just for fun. Not regulating nuclear energy makes it cheaper but seems rather unsafe. (because humans, you know)
  • antris 10y ago
    I agree that their intentions are good, but you have to draw a line somewhere between cost and safety. Nothing we do is completely risk-free. You can get choked eating food, you can get into a car accident, yet food and transportation industries haven't been regulated to death. Why should nuclear be singled out, when it's already the safest form of energy of all time?
  • ageofwant 10y ago
    Fine, now please apply the same logic to coal plants that kill 7000000 people/year.
    • sqeaky 10y ago
      7 million per year. This seems outright false despite being as pro nuclear as I am. Can you back this up?
      • antris 10y ago
        I think the number is actually the total for global deaths in air pollution: http://www.who.int/mediacentre/news/releases/2014/air-pollution/en/ http://www.who.int/mediacentre/news/releases/2014/air-pollut... Coal is not the only contributor, but still a major one: http://www.scmp.com/news/china/article/1632163/670000-deaths-year-cost-chinas-reliance-coal http://www.scmp.com/news/china/article/1632163/670000-deaths... 670,000 reported deaths because of coal annually in China

    It's not that the regulations are ill-intentioned but currently they are preventing safer technologies from being implemented because it costs billions of dollars to get technologies licensed properly.
• mtgx 10y ago
  > Mainly due to politicians drafting rules to require more safety out of nuclear than any form of other energy solution. I wonder if that's because of things like Fukushima... You can't have it both ways. 1) Nuclear is safe because there are regulations - Fukushima just had bad safety policies implemented. That's all and 2) We can't have too many nuclear regulations - that would make nuclear too expensive! Solar/batteries are the future. They are both going to drop in price by multiples over the next decade, and then some more after that. I also think there are very few companies that wouldn't rather build solar/battery power plants now, even if more expensive to build at first, but much cheaper to maintain later, than deal with the complexities and regulations and uncertainties of nuclear power plants. Nuclear should've "won" 30-40 years ago with the whole "too cheap to meter" thing. It's too late now. There are much better alternatives that are close to being competitively priced, or will be soon enough.
  • mseebach 10y ago
    No, we can't have it both ways, which is why we're explicitly asking to not have it both ways. Let's apply the same level of rational risk tolerance to nuclear power as we do to all other power sources. Nuclear isn't 100.00% safe, but it's already a lot safer than any other source. People die from falling off roofs when installing solar and nobody bats an eye because shit happens and life goes on. Let's accept that nuclear is extremely (if not absolutely) safe, and make sure we learn from mistakes, accidents and near-misses when they do happen -- like we did (and do) with aviation.
    • jschwartzi 10y ago
      I think the difference in attitude comes from how /specific/ a risk factor is. Falling off a roof is very specific to the person doing the installation, and it's easily foreseeable to the installer. This makes it easier to ignore. In contrast, fallout from a reactor failure is very general. You basically draw some distorted circles on a map, and everyone in those circles is affected. It's way more terrifying because you have basically no control over the risk once a reactor is built. Worse, if you lived in the area before the reactor existed you've just gained a new risk factor. If you're a homeowner you can pack up and move, but that's a major undertaking to avoid a risk that someone else created for you. In contrast, the solar installer has direct control over their exposure to the risk. They were aware of it before entering the situation, and they can eliminate the hazard at any time by quitting.
• skybrian 10y ago
  Nobody died from Fukoshima but a large area had to be evacuated. When calculating the cost of nuclear power, you have to include the cost of insurance to cover relocating the surrounding communities in case of an accident. And if anyone did require power companies to have this insurance, it's likely that nobody would invest.
  • nickff 10y ago
    If you require power companies to get all this insurance, you no longer have any reason to regulate them (using the government), as there are no externalities (because the company bears the costs of a failure). This might be a good trade-off, as insurers are likely to be more judicious and less political with their inspections and requirements.
  • paulmd 10y ago
    Similarly, we should also cover the cost of insurance to cover areas contaminated from coal fly ash spills (including waste seepage downstream, not just direct coverage). https://en.wikipedia.org/wiki/Kingston_Fossil_Plant_coal_fly_ash_slurry_spill https://en.wikipedia.org/wiki/Kingston_Fossil_Plant_coal_fly... If other power sources had to factor in the full costs of such contamination they would be uneconomical as well. We need to have power if we want to have nice things, it's purely a question of figuring out how to do it in the most responsible way possible. For that matter we should probably also factor in upstream contamination - landscape destruction due to large-scale strip mining for coal [1], or pollution from lithium/neodymium refining and silicon fabrication. These are measures where uranium mining has essentially zero pollution but both coal, solar, and wind all have fairly significant pollution footprints.

    > Nobody died from Fukoshima but a large area had to be evacuated. When calculating the cost of nuclear power, you have to include the cost of insurance to cover relocating the surrounding communities in case of an accident. Sure, but again you need to compare like with like. How many people relocated per megawatt? The numbers for the alternatives are worse.

  > ... Fukushima, where zero people have died or gotten sick due to radiation No one has died of outright first-order radiation poisoning, but it's a specious claim with respect to long term cancer rates since we lack the tools to pinpoint the cause of a cancer death. Workers have received high does of radiation, and some models predict hundreds of future cancer deaths (but some models predict zero). Even if someone in the exposed population were to die, we would be very unlikely be able to say for sure if that death were due to 'natural' cancer or cancer induced by exposure to some substance leaked. That doesn't make the exposure or the technology safe. https://en.wikipedia.org/wiki/Fukushima_Daiichi_nuclear_disaster_casualties https://en.wikipedia.org/wiki/Fukushima_Daiichi_nuclear_disa...
  • antris 10y ago
    Yes you are correct. As I mentioned elsewhere (https://news.ycombinator.com/item?id=12725402 https://news.ycombinator.com/item?id=12725402), I made that statement under old information. I stand corrected. But the larger point still stands about nuclear being the safest form of energy we have. Even the worst case scenario of 600 eventual deaths won't sway the numbers for nuclear very much. My argument isn't that nuclear is 100% safe, I'm just asking for it to be honestly compared to the alternatives.
• lamontcg 10y ago
  > > Costs > Mainly due to politicians drafting rules to require more safety out of nuclear than any form of other energy solution. Of course it's more expensive if it's 100x more regulated. I've read this online in one form or another for the better part of 10 years. I've never seen a single actual study to back it up.
  • antris 10y ago
    Which part of it is questionable to you? That nuclear is more regulated than other forms of energy? That regulation increases building costs?
    • lamontcg 10y ago
      That regulation is the cause of the bulk of the costs and/or that regulation is the cause of nuclear's negative learning curve. There's an assertion here that nuclear would be cheap if only it wasn't regulated so tightly, and I've never seen an actual cost-breakdown to support that.
