China and South Korea are making a big fuss about it, despite producing and releasing more tritium than Japan.

Just a few minutes ago, The CPC (Communist Party of China) stated that it is suspending all imports of Japanese seafood to protect consumers.

> As expected, China has imposed a blanket ban on all Japanese seafood.

> Beijing announced some restrictions last month, but they were limited to 10 prefectures in Japan, including Fukushima and Tokyo. Earlier this week, Hong Kong announced a similar 10 prefecture ban on ‘aquatic produce’.

> South Korea, too, still blocks seafood imports from the Fukushima area. It's a ban that's been in place since 2013 and, although the government's political stance has softened, it is one that it has no intention of lifting.

> These are major customers for Japan and represent a lot of lost business. Nowhere buys more Japanese seafood than mainland China, which imported more than $600m worth last year. Remarkably, Hong Kong is only just behind - spending $520m on marine produce from Japan.

> Given China's consistent and vocal opposition to the wastewater release, it's a scenario that Japan's government probably envisaged. In the short-term, it admits businesses will take a 'significant' hit.

> In this sense, China understands the economic leverage it has over Japan and the question is whether Hong Kong will follow the mainland’s lead with another all-out ban.

> Either way, we're talking about major disruption for Japan's seafood industry and for restaurants in Hong Kong and China.

Source for claim that South Korea releases more than Japan?

Annual release of tritium:

2020: South Korea Wolseong Nuclear Power Plant and others Total: 365tbq or 1,022mg

The total amount currently stored at Fukushima is around 860tbq, intended to be released over the course of 30 years.

So divide by 30 and that is around ~28tbq a year.

Either way, the halflife of tritium is around 14years, and it's everywhere in the ocean. This is actually a nothing burger.

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

Gotcha. "as of January 2023, approximately 70% of the water stored in tanks still contained radioactive materials at concentrations exceeding the regulatory standards, in addition to tritium, due to such reasons as failures in purification equipment" -- so what's left is a matter of trust that they have got their equipment working and the actual water released isn't still contaminated.

Bottom line point stands, more is released regularly and this is nothing compared to the initial deluge of untreated material from the accident itself.

It’s not just a matter of trusting the Japanese government. The IAEA is also there to verify that things are as they say.
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.

I never expect morals from large agencies. Have they allowed independent testing at the release point for the more dangerous isotopes?
For the former point, fair enough.

For the latter, obviously yes. The IAEA (International Atomic Energy Association) has done it's own independent tests, as well as actively monitored japanese tests while on site.

Good, the oceanic ecosystem is being destroying by fishing.
China will just illegally fish it itself
That is definitely true.
