Nuclear waste can basically be safely solved by dumping sealed containers into the sea. We're talking about extremely small amounts of waste. A swimming pool can contain a year's supply of waste, and 20 ft of water is extremely effective radiation shielding. The ocean is so large that this would be totally negligible even if the worst happened.

It's been done before.

It wouldn't be negligible. Dumping all our HWL waste (250,000 tons) would increase background radiation of the oceans by 10% if completely mixed, but of course oceans are not. We would simply end up with highly radioactive areas of ocean if and when the containment failed.

Just a throwaway idea, but instead of radiating the whole ocean evenly, why not dump it in the already highly radiated nuclear weapon test zone? The US blow around 100 nukes and I wonder if a few thousands of tons would actually do much worse compared to what already down there.
