Measuring radioactivity in ocean units is a nice way of testing this. The world ocean naturally contains radiopotassium that produces 1.8 gigawatts of radiation and uranium that, with its various radioactive daughters, produces 400 megawatts. Other minor natural radioactivities also exist but don't change the total, 2.2 gigawatts, enough to matter.
This is a nice size of unit because it's midway between the very large amounts of radioactivity that naturally exist in the continents, thousands of ocean units, and the rather small amounts that exist in typical nuclear power waste caches, e.g. the containers seen in the background at https://www.dropbox.com/s/pwgb0ahfuv1lejb/Screenshot_2016-12-26-10-20-51.jpg?dl=0 . Each of them contains about a millionth of an ocean unit, about the same amount that got *into* the ocean as a result of the Fukushima meltdowns, but could not duplicate even that very slight contamination because their contents are too old to have any self-melting potential. If dropped in the ocean, each one would just lie on the bottom, keeping its micro-ocean-unit to itself as it diminished to a nano-unit (a billionth) and beyond.
So when we ignore the disposal of nuclear power waste, it's because it has never been a genuine concern to anyone. In this we behave rather like the Greenpeace associate seen pretending to pull a boat at http://www.x-journal.com/member/owe/?xjMsgID=3443 . If nuclear power waste were a genuine concern, the waste-to-be in the two reactors he's posing with, being a thousand times more radioactive than it will be when it attains waste status, would be a concern a thousand times more genuine.
Re: “Biden's nuclear bailout is a tragedy”
When government allows the production of a cubic inch of nuclear waste, it loses a cubic inch of *money*.
So, ending support for it, good deal? Not entirely. The money is fossil fuel tax and royalty revenue. Uranium replaces those fuels at pennies on the dollar, so there is no way nuclear power producers can, so to speak, make government whole.
Of course government was never really entitled to that fossil fuel money. No-one is.
But they want it, and they lie for it. Among the lies is stuff like "high-level radioactive waste with nowhere safe to store it for the hundreds of thousand of years that it remains lethal". In practice it has never been lethal at all, and to the public, including "environmental justice communities", it has never even caused injury.
In theory it will be 100 times less dangerous, many thousands of years hence, as it is in these present decades, the ones in which it has established a perfect safety record.
