Unfortunately I have to side with (or at least humor) the reddit libs on this one. People are so propagandized against anything to do with nuclear power that it's hard to judge whether their concerns are reasonable or fictional. Like, the way tritium is disposed of everywhere else is IIRC to more or less just dump it into the ocean (though obviously in a more controlled setting). Obviously state-level actors like China raising concerns adds credence but as far as I know, the IAEA are trustworthy as well. At any rate, I'm still not convinced without seeing actual numbers on eg how much tritiated water there is.

All that said eh they could just build more storage tanks

I agree with the libs on this one.

"The water is being treated by what’s called an Advanced Liquid Processing System, which can reduce the amounts of more than 60 selected radionuclides to government-set releasable levels, except for tritium, which officials say is safe for humans if consumed in small amounts.

About 70% of the water held in the tanks still contains cesium, strontium, carbon-14 and other radionuclides exceeding government-set levels. It will be retreated until the concentrations meet those limits, then diluted by more than 100 times its volume of seawater before it is released. That will bring it way below international safety limits, but its radioactivity won’t be zero."

the objections are all dishonest

Super heated ocean + spicy water + 6th mass extinction event + hurricane season

What could go wrong?

They couldn't care about what long-term accumulation would do to the environment,

This isn't a "steady state" or constant flow of concentrated waste, right? This is a transient event, as far as I understand it. It's not like with micro plastics, where more and more of the waste accumulated (and continues to accumulate) over time.

The approach to disposal sounds reasonable.

Record high ocean temps, mix in some radioactive waste, what could go wrong

If India could get a spaceship to land on the Moon. Japan could send this water out into space.
