It might be true that nuclear power produces less waste but we have to consider the scales of global energy demand, multiply it by the time scales of nuclear waste to reach what threshold exactly? When and how would nuclear waste become a problem. Would it take ~200 years like the industrial revolution with CO2? Would it be okay if it where 300 years? or 500? What do we do, when background radiation is rising from ground water and soil? Switch back to natural instead of green energy, hoping the next millenias will be fine?
I dont think nuclear power is a solution. It can be step in an energy transition strategy, but no solution.

- greenavocado 1y agoWhat happens when the rocket explodes on the launchpad or at several thousand feet ASL?

Never. If there is ever "too much" of it we reprocess it as per OP article to remove the "non-usable" stuff and burn up the rest. It seems that there's an order of magnitude reduce by recycling (96% is usable fuel, so 4% is left over): * https://www.orano.group/en/unpacking-nuclear/all-about-radioactive-waste-in-france https://www.orano.group/en/unpacking-nuclear/all-about-radio...

- throw0101a 1y agoGetting smacked with an asteroid like with the dinosaurs is also a source of concern. This endless list of nit picky objections that go on and on and on and on and on, that are brought up no matter how low the probability, is why we can't have nice things (like cheap, reliable, zero-emission electricity available 24/7). More people will die from plane crashes—which is amongst the safest ways to travel—than from nuclear waste radiation in the next few hundred years. Geraldine Thomas, the co-founder of the Chernobyl Tissue Bank, says there are more worrisome things than radiation: * https://www.theguardian.com/environment/2011/apr/26/obesity-smoking-more-dangerous-radiation https://www.theguardian.com/environment/2011/apr/26/obesity-... * https://en.wikipedia.org/wiki/Geraldine_Thomas https://en.wikipedia.org/wiki/Geraldine_Thomas I personally live about 50km nuclear reactor and don't think about it at all. * https://en.wikipedia.org/wiki/Pickering_Nuclear_Generating_Station https://en.wikipedia.org/wiki/Pickering_Nuclear_Generating_S...

A nuclear reactor and its waste threatens everyone, even very remotely and in a distant future. Note: my own brother was killed during a jetliner crash (Swissair SR111, 1998).
- fastball 1y agoIt is actually not that hard to make something water-tight if you have no intention of opening it again. > I dont think nuclear power is a solution. It can be step in an energy transition strategy, but no solution. Do you mean nuclear fission specifically? Because I can't imagine anything being a long term solution except nuclear power (fusion).
