  • Do you read the articles linked? The EPA doesn’t give out the actual numbers, the numbers you use are for lightly toxic and radioactive material. The caskets will not last 200 years

    encaseing isn’t a option, concrete expands when drying and would crush the containers of the material, wich is just making it easier for water to get in, furthermore concrete is Corrosive and should not touch the waste containers in general.

    Roman concrete is the worst example you can give, its super bad at protecting against water, and it lasts because the concrete is actually not as well made as ours, ours is better mixed and can hold way more load, theirs had faults, wich is the reason why it’s still standing, water gets in, activates the hardening process again and “its fixed” its not safe to use that stuff for nuclear waste or any modern building.

    And you again make a wrong call, it takes over a Million years to get most of the waste to be lead, the stable end product of uranium. The stuff isn’t safe before that state, even lead is still toxic, although more manageable, anything before is extremely toxic and is radiating. Its not safe after a given period, its safe after its tested safe, not a single second before that. Radiation isn’t a joke, especially prolonged exposure.


  • There is no material known to man (or woman) (wich we can effectively build with) that lasts 100 thousand to 1 Million years (wich is necessary for such things)

    We cannot build such a building from pure gold or titanium (wich both wouldn’t last long enough either, but significantly longer than concrete) a structure like that has to be rebuild at least once in 100 years, if not every 50 years, wich is more reasonable. It will cost humanity for all eternity to keep the environment safe from this waste.

    Forgot to add, NO, nuclear, or rather toxic contamination of ground and surface water has the ability to be a super serious environmental issue for very very large areas. We humans produced stuff that might outlast our species, its not just nuclear waste, there is also regular toxic waste with similar storage issues wich we cannot dispose off and that has to be stored in a similar manner, just the need for radiation shielding is not there, but water and air are the biggest enemies of human architecture and long lasting storage solutions.

    There is no such thing as forever lasting human buildings or burrows. They will always be a huge burden.
