The Japanese government decided on Tuesday, Pour contaminated water into the Pacific Ocean After processing to remove most of the radioactive elements, it was stored in the damaged Fukushima nuclear power plant.
This controversial measure aims to resolve Accumulation of radioactive water At the first nuclear power plant, this is one of the most pressing issues in the complex decommissioning process, which has been compromised by destruction The earthquake and tsunami in March 2011.
Prime Minister of Japan Suga Yoshihide, After a meeting with the government cabinet, the decision was made on Tuesday and then submitted to consultations with the power plant operator Tokyo Electric Power Company, Japan’s nuclear regulatory agency, the International Atomic Energy Agency (IAEA) and local authorities in Fukushima. other parts.
Since the beginning of last year, the Japanese authorities have been choosing to discharge water from factories in a controlled manner. Think it is the most feasible Among many other technically more complex options.
However, due to opposition from the Fukushima government and local fishermen’s associations, the decision was postponed. They believed that the leak might Further damage their economic activities, The nuclear accident in 2011 suffered the most severe blow.
Japanese authorities believe that the leak Will not cause any risk to human health Because the level of of released into the ocean will be lower than the national health standard (because it is mixed with seawater), they argue that it is Usual practice In the nuclear industry of other countries.
It’s the water stored in a huge tank, from Cool down the damaged nuclear reactor core, As well as underground aquifers and rainfall that infiltrate and eventually become contaminated with radioactive isotopes.
Fukushima Daiichi Nuclear Power Plant’s facilities Processing system Water that removes most of the radioactive substances considered to be dangerous, except with, is an isotope that exists in nature, albeit at a very low concentration.
More 1.25 million tons The treated water of the first water is stored in the factory of the first plant, and it is expected that its storage capacity will be exhausted at the current rate of liquid production next fall.
