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.
> 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).

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