Napkin math of 1.25 million tons of water is about 34,000 tanker trailers, or 3 a day over 30 years. So why doesn't JP just dump it in Lake Inawashiro a couple hours drive west? It's safe after all. Cost seems trivial. Except no one trusts TEPCO. Least of all the Japanese. Why would region trust JP any more? Dumping is offloading a domestic political problem to an international one because radiation + Japan + politcs = bad time. Enough that they're willing to give up to 600M in fish exports per year instead of dumping this very safe water on Japanese soil.

Why does this only compare tritium, which is the supposedly safe material? What about "cesium, cobalt, lithium, and strontium" which are supposedly more dangerous?

Because it is filtered out by every nuclear power plant that has an inkling of basic morals?

The only materials that aren't filtered out are Carbon14 and Tritium, if I remember correctly.

These facts won't convince people who believe in homeopathy, of which there are plenty. Of course there shouldn't be a controversy, but it doesn't surprise me in the slightest that there is, considering the amount of anti-scientific sentiments in the general population.

If I shit in the ocean, does the ocean become highly potent and poisonous because its highly diluted shit?

According to homeopathy, it does become potent, yes, but not poisonous, because it will magically heal whatever disease ingesting shit causes.

With one caveat: homeopathy says that the water has to be diluted by a certain process which involves tapping it ten times during full moon or some non-sense like that.

So people don't trust the Japanese government or TEPCO. That's fine, and that's why the IAEA is there monitoring. Don't trust the IAEA? I feel like anyone should be able to conduct independent testing on water and fish samples from the area.

China are making a fuss about it but it's just an excuse for geopolitics.

This was exactly what I thought when I first started hearing about this, and is even more what I think now after hearing statements from China.

China's statements are sleazy in my opinion. The way they word things makes it sound like Japan is irresponsibly doing whatever they like without oversight, and the world should be doing something about it.

The reaction of China and South Korea is hilariously hypocritical. Both countries have been dumping nuclear waste water in the ocean for years - and continue doing that. Geopolitics at it's worst.

So why not dump this very safe water on Japanese soil? There's lakes and reservoirs a short drive away. A few tankers a day over 30 years to clear up 1.25 million tons is cheap to losing 600M of fish exports per year to PRC and barely impact local enviroment on time scales involved. Maybe inspire some new Godzilla movies. Oh wait, it's because Japanese domestic politics wouldn't allow it. So gov would rather internationalize the issue.

Japanese domestic politics at it's worst.

Source?

Last 50+ years of history especially, but pretty much as much history as you can find for the region.

Those elements have already been filtered out [1]:

> Radioactive materials such as cesium, strontium, iodine, and cobalt are purified by ALPS through co-precipitation treatment using solutions and adsorption on activated carbon and adsorbents. Almost all radioactive materials are removed through repeated treatment by ALPS, but tritium, which is a radioisotope of hydrogen, exists as a part of the water molecule and cannot be removed through treatment by ALPS and other equipment.

It's only tritium that can't be removed (and that is why it is released by other nuclear power plants - in larger quantities that is planned here - as part of normal operation).

To be fair, TEPCO is completely and absolutely untrustworthy. There is evidence of severe miss-management, as well as 2 cases where they deliberately ignored safety warning from government agencies. As a Japanese citizen, I would feel safer seeing the TEPCO corporation dismantled, and it's leadership behind bars. But the courts declared them not guilty. A late addition, but I should also add info about Onagawa Nuclea…

They seems to be more willing to put money on propaganda instead of actually dealing with the problem. Just check the page 7.

- Discharge into the sea: 3.4 billion yen

- Vapor release: 34.9 billion yen

- Hydrogen release: 100 billion yen

- Underground burial: 243.1 billion yen

And for propaganda, 70 billion yen

Serves me right for wanting to properly translate my own language, forgetting some other countries have the same names. Thanks.
