Scientists say impact of long term low-dose exposure to the environment and humans are unknown, and that tritium can have a bigger impact on humans when consumed in fish than in water.

That's horribly vague and I don't know if it is purposeful and accidental.

Tritium has a really short retention (respectively).  If someone is exposed to it, you need to get a urine sample from them within 10 days (or less) or you may not detect anything and thus not know the internal dose they received.

I personally knew one of the worst (probably) tritium exposures....well...ever.  He had to pee into a sample container for two weeks and the doctor told him to drink lots of water (and beer, incidentally).  I don't remember his exposure from that one.

Going through all the plans of this, this was my suggestion all along: dilute the water and pump it down a pipe that discharges offshore so currents can mix all the waste water and carry it away.

Nice to see they adopted my plan for fixing this problem.

No reason to complain with all the things we put in there every day that are far worse. This is just something that the brain damaged monkeys who think nuclear power is the devil will amplify

I thought they had already approved this years ago. Maybe that was just an emergency release or something.

Do you want Kaiju?  Cause this is how you get Kaiju.

trialpha: I thought they had already approved this years ago. Maybe that was just an emergency release or something.


It was discussed years ago when the amount of water being dumped into holding tanks was getting to be too much.

I think the initial discussion was about raw dumping the water without treatment, as in loading it into some tanker ships and taking it far out into the Pacific (a few hundred kilometers) and pumping it overboard. That would result in a lot of different radioactive contaminants dumped into the ocean, but it would have been the proverbial drop in a bucket when considering the entire volume of the ocean. It would amount to nothing, but the optics were still bad.

The revised plan is to filter the water through some resin or something like that where it will capture everything other than the tritium, which is basically impossible to separate out of the water. This result is taking just the tritium in the water, diluting it a bunch, and then diluting it even more by putting it into the ocean.

Dilution is the solution to pollution.

A favourite line from my environmental economics class:
"The solution to pollution is dilution."

Time is the solution for radioactive waste.  And by now any radioactivity either never mattered or has burned itself out.

And look how well dilution works for carbon dioxide.  Maybe simply littering the planet with our trash isn't the answer.  Maybe something like a landfill instead of dumping the trash to the wind is a better idea.  Like reusing nuclear fuel stocks and glassifying the waste and burying the glass.

It's going to be done over 30 years, so that's really REALLY diluted.

Wait, but by the rules of homeopathy, the more they dilute it, the syringe it's effects!

Yes, I'm sure the nuclear experts have no idea what they're doing here. Let's be outraged.

And that's why we have PFAS and microplastics in our blood, and are now dealing with global warming. There is no "out there" that doesn't become "in here" on Earth. Anything you dump on the environment slowly builds up and goes everywhere.

That was always just cover for polluters.

What is your plan for dealing with the water? It's got to go somewhere and releasing it into the ocean hurts nothing.

At some point they will have to filter and dump some tritiated water. If it's sufficiently dilute, and old enough that much of the tritium has decayed, I don't have a problem in this case.

But saying "dilution is the solution" is idiotic. Tritium at least decays fairly quickly. There are plenty of things at that disaster site that have much longer half lives and can't be released into the environment in any way.

The solution to pollution is not to make dangerous things, and to safely handle and dispose of dangerous things you have to make. What you release into the environment can't be just whatever. The entire history of the 20th century is learning that a "little bit" of lead in gasoline or a "little bit" of CFCs or a "little bit" of PFAS quickly become a big problem. Some things have to be just put in storage for decades or centuries (in the case of nuclear stuff), some things have to be chemically altered to render them inert, some things can be diluted - but dilution and release into the environment is the worst solution, the last ditch scenario when you don't have another choice and you know it's at a safe level - safe enough YOU would drink it.

I have zero concerns about this. The water will be so diluted in the oceans that it is irrelevant.

Great. Good job. You're correct.

Work to fix it in the future, but it has nothing to do with the job at hand.

Grand Gulf has released tritium into the Mississippi River with very little outcry.
