According to the Greenpeace investigation, contaminated water from the destroyed Fukushima Daiichi nuclear power plant will be released into the sea, according to the Greenpeace investigation.
Environmental groups claim that 1.23 million tons of water stored in more than a thousand tanks in the plant contain “dangerous” levels of the radioactive isotope carbon-1 dangerous, as much as tritium has already been widely released.
Report Releases by 2020: The Reality of the Fukushima Radioactive Water Crisis Japanese media reported that local fishermen were close to approving the release of water into the Pacific Ocean despite objections. The move will make their living.
“We cannot postpone the issue forever,” Prime Minister Yoshihide Suga said this week. “We want to make a responsible decision as soon as possible.”
While most of the focus is on tritium – which cannot be removed by the site-filtration system used by the plant operator Tokyo Electric Power. [Tepco] – Greenpeace Japan and Greenpeace East Asia have reported that radioactive carbon in stored water will also be released.
Carbon-14 has a half-life of 5,370 years and becomes “included in all living things,” the report said.
“It concentrates in fish at several times higher levels than tritium. Carbon-1 is particularly important as a contributor to the combined human radiation dose and has the potential to damage human DNA. ”
It refers to the Japanese government and Tepco water – which is stigmatized when used to cool tree tsunami-damaged furnaces – as “treated water” and gives the impression that it contains only tritium.
Tepco’s advanced liquid processing system removes highly radioactive substances from the water, but a radioactive isotope of hydrogen cannot filter the tritium that nuclear power plants regularly mix with water and dump into the ocean.
Greenpeace said it had confirmed with TEPCO that the system was not designed for carbon-1 removal.
“Nearly 10 years after the start of the disaster, TEPCO and the Japanese government are still covering the crisis in Fukushima Daiichi,” said Sean Barney, author of the report and senior nuclear expert at Greenpeace Germany.
“They have kept detailed information on radioactive substances in contaminated water for years. They have failed to convince citizens of neighboring countries such as Fukushima, Greater Japan and South Korea and China that the polluted water dumped in the Pacific Ocean contains dangerous levels of carbon-14.
“These together with other radionuclides in the water will remain dangerous for thousands of years with the potential for genetic damage. Another reason to abandon these plans.
The Japanese government is expected to announce a decision on the fate of water next week. Media reports say the project will begin early in 2022 and will take decades to complete. Yomiuri Shimbun magazine says that water from the Fukushima Daiichi River will mix inside the plant before it comes out so that it is 40 times less dense.
Pressure is mounting on the nuclear plant site to decide on the site of the contraction, with TEPCO estimating that all available tanks will be full by mid-2022.
