OR, you put the nasty and long-lived radwaste into (say) lead barrels, and bury those below some nice, deep, easily-monitored ocean trench. Absolutely nobody's going to accidentally dig those up. And if the effort needed to intentionally do so would be greater than the effort to brew their own fresh radwaste, then nobody will bother trying that, either.
- wkat4242 2y agoBarrels don't last when filled with nuclear material. The radiation embrittles the materials over time, they wouldn't last 100 years. And then all that crap will be released into the ocean and swerve all over the world.
- bell-cot 2y agoAssume that the folks building the barrels know about the embrittlement, and have both a decent budget and some experienced engineers to mitigate the problem. Also note my phrase "bury them". Radwaste is not some magical Sealed Evil in a Can. If bound in compounds with substantially higher density that the ocean sediments, and emplaced a few tens of meters below the sea floor, then gravity will quite strongly discourage its upward migration.
- Kon5ole 2y agoFour decades of studies by experienced engineers and a very decent budget to figure out how to store US nuclear waste has resulted in 0 solutions so far. I think we can safely assume that dumping it at sea is not an option.
- zdragnar 2y agoWe have solutions in the US, but politicians keep playing games. Yucca mountain has been authorized and de-authorized back and forth for decades. It isn't an engineering problem at all.
- bell-cot 2y agoTrue-ish - but those game-playing politicians don't have much freedom of choice, if they want to keep their jobs. The US nuclear establishment has earned itself a "bungling pathological liars" reputation with the public. Why would the average voter react well to any "we'll store a whole lotta Bad Stuff near you" plan?
- jenadine 2y agoNuclear material is put in glass which can last many thousands of years. Geological studies of the locations where the nuclear waste is burried show that it would take millions of year for the isotopes to escape. Meanwhile, the effects of low dose radiations on health are vastly exaggerated. Every industry is releasing pollution in the ecosystem that are way more toxic and dangerous. And these get barely any attention for some reasons.

- pvaldes 2y agoPeople keep proposing that nonsense from 70's but can be cured studying some really basic biology and oceanography. In 2024 is at a level similar than saying that smoking is good for your children. Is not even funny as a joke. > Absolutely nobody's going to accidentally dig those up Read about the concept of vertical migration
- bell-cot 2y agoAre you referring to this? https://en.wikipedia.org/wiki/Diel_vertical_migration https://en.wikipedia.org/wiki/Diel_vertical_migration If so, Wikipedia's first para makes it clear that that migration occurs at vastly shallower depths than an ocean trench.
- pvaldes 2y agoWhy do you think that people spend decades studying and mastering a field where they could just instead read a page of Wikipedia? There are hundreds of entire books about marine ecology and sea physics. Thick books with entire chapters about how energy/matter moves up and down in the ocean. There are more than one type of migration and we don't still know a lot of things about the sea. Physics tell us also that warm water tend to ascend over cold water, and that the water is moved from very deep areas to some coastal areas just because the shape of continents. To achieve the same effect of leaving a barrel of nuclear waste in the middle of the sea (hoping in vain that nothing will move from there) we could better to put nuclear dust in the way of a stampede, or leave the barrels in the beach before the tornado season. Would achieve the same effect but saving much more money.

- bell-cot 2y agoMy understanding is that the anti-proliferation lobby* is intensely allergic to several of the technologies involved in doing that. *EDIT - I'm referring to the US-centered anti-proliferation lobby. Though "national security establishment" might be a better term. And yes, its ability to influence French, Japanese, etc. domestic nuclear power policy is much more limited.
- Moldoteck 2y agoi mean, france does purex, japan too, soon us too. fast reactors are slowly rolling out in some countries like india, china, russia, even eu has some projects in mind
