What other direct or indirect sources of deaths are there from nuclear power?
- Ma8ee 6y agoMining and transport of uranium ore, processed fuel and nuclear waste. I don’t know how significant those are. My main concern with nuclear power is that they still haven’t managed to create any active long term storage of the nuclear waste. And before that, we don’t know the full actual cost of the energy.

And before that, we don’t know the full actual cost of the energy. That's a red herring. The "waste" has a lot of energy remaining (otherwise, it would not be radioactive [1]). There are reactor designs that can use "waste" from current reactors as fuel. Only, we're not building them. Because coal is better or whatever. [1]: that's bit of a shortcut, but elements that undergo radioactive decay on timescales that make them dangerous are unstable enough, you can put them in a reactor and poke them to undergo that decay faster and get you electricity.

There are reactor designs that can use "waste" from current reactors as fuel. Don't these reactors produce nuclear weapons products? Seems like that may be a reason we don't want a lot of them around.
- dodobirdlord 6y agoRather, their fuel is plutonium. There's lots of plutonium in spent reactor fuel that can be extracted into more pure plutonium and used as fuel, but also to build nuclear weapons.
- pfdietz 6y ago> Only, we're not building them. Because coal is better or whatever. No, we're not building them because they are more expensive than ordinary LWRs, uranium is cheap, and separated plutonium from spent fuel has negative value.
- Ma8ee 6y agoNo, it is not a red herring. It doesn't matter that it in theory has a lot of energy remaining if there isn't any cost-efficient and safe way to extract it. And the reason we aren't building them is because other forms of energy, including wind, water and sun, are cheaper.
- aksss 6y agoI haven't kept up on it, but aren't travelling wave reactors supposed to use the spent rods from light water reactors?[0] Seems like an elegant use of nuclear waste. There was an argument made last year [1] that the problem with nuclear power generation is that everything we have in production is 50+ yo technology. Modern reactors are far cleaner, far safer, but the political hurdles for regulatory approval and NIMBY hurdles are enormous barriers. Incidentally, if we're considering mining and transport of base resources to be part of indirect deaths, let's not forget that our renewable infrastructure relies on very dirty mining and transportation processes for quartz, rare earth minerals... and coal!

- Ma8ee 6y agoThere are always a lot of interesting research projects brought up about what to do with the nuclear waste in the future. But never anything cost effective actually in production yet, and it's not like they haven't hade some decades to get them going. If we can cite <future technolog> as our solution, I suggest that we go with fusion reactors directly. The main barriers for building new nuclear plants are that they aren't cost effective, so no one wants to invest in them. I'm certain they could be built cheaper without regulations about safety and funds for long term storage of waste. But I don't think we want to go there. (Your second link directs me to a documentary about Bill Gates. How is that relevant?)
- pfdietz 6y agoThere is a straightforward, economical, and practical approach to dealing with spent fuel: sealing it in dry storage casks. This is cheap, good for at least some centuries, and forecloses no future options for its disposition. Why do anything else now?
- Ma8ee 6y agoNo, it’s not good for some centuries. Corrosion and other processes that aren’t fully understood how they are affected by radiation make it hard to make any leakproof containers that will last even one century. Also, above ground storage is vulnerable both to changing climate as well as changing political circumstances. Finally, even if all of the above was overcome, it’s just a way to push the problem to future generations. I’d be quite upset if our generation would have to deal with a hundred thousand tons of radioactive waste in old corroding containers without getting anything for it.
- Tuna-Fish 6y ago> Mining and transport of uranium ore, processed fuel and nuclear waste. I don’t know how significant those are. Completely and utterly insignificant, to the point where it is downright insulting when they are brought into a discussion about how 10000 people die of coal-related air quality problems every year in Europe. > My main concern with nuclear power is that they still haven’t managed to create any active long term storage of the nuclear waste. And before that, we don’t know the full actual cost of the energy. Sure we have. https://en.wikipedia.org/wiki/Onkalo_spent_nuclear_fuel_repository https://en.wikipedia.org/wiki/Onkalo_spent_nuclear_fuel_repo...
- toyg 6y ago> Sure we have. Basically we just bury it and hope for the best, it will be someone else's problem anyway. > The Onkalo repository is expected to be large enough to accept canisters [...] until around 2120.[13] At this point, the final encapsulation and burial will take place, and the access tunnel will be backfilled and sealed. We go from "dig it out" to "dig it in". Very sustainable. /s
- annamargot 6y agoHow much volume are we talking here and how frequently would it need to be disposed of? I recall reading somewhere that it’s a very manageable amount.
- renaudg 6y agoIndeed. For example, the 9TWh required to power France's high speed train fleet for a year produce 200kg of nuclear waste. Since the beginning of the country's nuclear programme, the total cumulative volume is 3650m3 of waste : one olympic swimming pool's worth of it. https://news.ycombinator.com/item?id=21996751 https://news.ycombinator.com/item?id=21996751
- ShroudedNight 6y agoWhat percentage of potential energy is extracted? My (old, probably out of date) understanding is that (at least in Canada) nuclear facilities limit themselves to extracting some tiny quantity of the potential energy in order to avoid producing material that could be made into nuclear weapons.
