| Sure, but has anyone ever built a container that lasts 30k years, and remains watertight? Thus far, most off-site containment storage sites over 10 years old have failed to stop containment leaks, Radon gas diffusion, or hot-material fires. Fission reactors are a 1950's loss-leader technology, and only make sense for already uninhabitable areas like space. =3 |

| There are plenty of dry areas like in the American Southwest which can be projected to not have meaningful water attempt ingress in that time frame. Also, fission reactors make phenomenal sense on aircraft carriers, submarines, etc. |

We have too many people to hydrate, too many crops to water in order to feed them, and not enough water. At some point widespread desalination is probably inevitable, but that requires a lot of energy. Or the public could accept a reduction in their standard of living, but that’s likely not happening without a civil war. | | |
| ▲ | atmavatar 5 hours ago | parent | next [-] | | We're also not even attempting to be smart about our water usage, particularly when it comes to agriculture. Growing crops in a desert that require significant amounts of water to grow is already pretty bad, then exporting the bulk of those crops overseas adds insult to injury. Of course, all that is made possible by our pants-on-head stupid water rights laws. | |

We'll also need somewhere to put all that salt. It'd be best to stop the largest wastes of the clean water that we have. We have plenty of water for people and food. We just have to stop the wasteful practices of industry and force them to be more efficient and responsible even though it will eat into their profits. | |

I suspect what we'll actually do is what we always do. Innovate our way into a higher standard of living while simultaneously elevating the poorest people out of poverty and finding novel ways to feed, clothe and house our population. It's funny how persistent malthusians are in the face of evidence to the contrary. | | |
| ▲ | iamnothere 3 hours ago | parent | next [-] | | We’ll see what that looks like in the face of demographic decline and increasingly expensive oil. It’s possible that some kind of technological miracle rescues us, but it seems more likely to me that we follow the pattern of catabolic collapse seen in the Bronze Age, Easter Island, and Europe in the Dark Ages. Civilization may rebound, sure, but humans have a history of overextension followed by decline (as do all animals). | | |
| ▲ | autoexec 3 hours ago | parent | next [-] | | A very small number of people are taking (and often wasting) the majority of the worlds wealth and resources and harming everyone else in the process.

Both the ash and uranium tailings are in the 50ppm range, but we make 100Mt per year of one of them and basically no uranium tailings in the US. Globally, the ratio is over 1Gt of coal ash and 10-20Mt of uranium tailings. One is currently a problem, the other isn't. | | |

| ▲ | Joel_Mckay 5 hours ago | parent | prev [-] | | I have a lower opinion of coal, more than any other energy source. From an economics perspective it also costs 4% more than solar now. There is no excuse to bring back 1800's steam technology. If you grill, use charcoal because it is short-term carbon cycle neutral. We have one of the largest global coal deposits, but it is also one of the most contaminated natural hot heavy metal sources currently known. Indeed, the natural run off has already closed many water wells for small towns in the area. =3 |

| ▲ | Joel_Mckay 3 hours ago | parent [-] | | Not sure why people buried your post, but many water-soluble metal salts are pretty toxic to animals and people. In areas with natural Arsenic accumulation (or Acid rain run off), farmers will sometimes place rusting iron equipment in the water ways to reduce metals accumulating in the topsoil. With low rainfall the evaporated well-water problem can certainly be a serious concern. =3 |

| > Sure, but has anyone ever built a container that lasts 30k years, and remains watertight? Why are people still proposing this antiquated 20th century storage technology instead of just building the newer reactor types that not only don't have this problem but are the best way to get rid of the long-lived isotopes we already have from 20th century reactor designs? The answer to what you do with isotopes with long half lives is that you put them in a reactor that turns them into isotopes with shorter half lives. |

| ▲ | AnthonyMouse 2 hours ago | parent [-] | | None of it is lies. The CANDU reactors Canada has been operating for decades can run on spent fuel from legacy reactors and China actually uses them that way. The US hasn't built any of them, or any of the other designs that can do the same thing, in significant part because people keep presenting the circular reasoning that we shouldn't build newer reactors without dealing with nuclear waste when we should be dealing with nuclear waste by building newer reactors. | | |
| ▲ | Joel_Mckay 2 hours ago | parent [-] | | Indeed, Canada was also indirectly responsible for many Nuclear weapons proliferation issues in North Korea, India, and Pakistan. Selling small research reactors to emerging economies had long-term consequences. As a side note, the CANDU are famously bad designs known to develop heavy maintenance costs even to remain operational. Yes these can run on garbage fuel, but only because other designs could never tolerate such waste. It is a teachable moment about legacy designs having unintended benefits as well. =3 https://www.youtube.com/watch?v=QNQu_3VQYAE | | |

Selling small research reactors to emerging economies had long-term consequences. What does that have to do with how the US can deal with spent fuel? The reactors that consume spent fuel are ordinary power generating reactors rather than small research reactors and the US already has nuclear weapons. > As a side note, the CANDU are famously bad designs known to develop heavy maintenance costs even to remain operational The CANDU design is from the 1960s. It's not what you would actually use for a new project, it's an empirical demonstration that reactors that run on spent fuel are a real thing that actually exist rather than merely a theoretical possibility. There are also modern designs under construction in Europe and the same company is partnering with a US company to permanently destroy some of the US government's cold war era plutonium. |

| I think storing nuclear waste was decided to be a bad idea a long time ago. I'm not a nuclear scientist, but I was under the impression that if something is radioactive enough to be a hazard then it's radioactive enough to generate power. Is that not the case? |
| |
| ▲ | Joel_Mckay 2 hours ago | parent [-] | | A brand new Uranium fuel pellet is often safe to hold with gloved hands for a moment. Spent fuel with complex decay isotopes must be kept under deep cooling pools with criticality control precautions. From a chemistry perspective, complex isotope products like Plutonium are more obscure to evolutionary biology, so it is often much more dangerous even in accidental trace exposures. I am just a sentient turnip that prefers distributed Solar products. Have a great day =3 |
