This water release might be a potential market opportunity for the SAFIRE III reactor as well as saving the Pacific ocean from radiation contamination.
Nope. There is no danger. The oceans and atmosphere have ~100,000 times more naturally occurring tritium than TEPCO will release. Global inventory: 2,590 petabecquerels. (2,590 quadrillion). TEPCO release: up to 22 trillion becquerels of tritium per year. 2,590 quadrillion / 22 trillion = 117,727.
Tritium is formed in the upper atmosphere from cosmic rays. It falls into the oceans and land. The half life is 12.3 years, but it is replenished by cosmic ray activity. Nearly all the tritium from atmospheric nuclear bomb tests is now gone. Most of the tritium TEPCO is releasing now will be gone by the time they finish releasing it 35 years from now.

"Around 140g to 200g of tritium is produced in the upper atmosphere every year. The Pacific Ocean contains around 8400g of tritium, while the total amount of tritium at Fukushima is less than 3g.
Japanese authorities plan to gradually release the water over a period of around 40 years. Each year, around 0.06g of tritium will be added to the ocean which will change tritium levels in the Pacific by less than 0.001 percent annually.
A recent study by two government institutes in South Korea used computer models to predict how Fukushima tritium moves with ocean currents. They found tritium levels in Korean waters would rise by less than 6 parts per million, a change too small to detect."
The Chinese are complaining about TEPCO, but the mass of tritium and other radioactive elements they release from their reactors and coal combustion per year is far greater than the TEPCO's tritium, and far more long lived and dangerous. China releases 112 trillion becquerels of tritium per year from nuclear reactors, and France releases 10,000 trillion becquerels per year. (https://www.tepco.co.jp/en/dec…ed-water-lan/index-e.html)
