The operator of the emergency Fukushima-1 nuclear power plant in Japan, the TERCO company, has completed the third stage of discharging treated water from the Fukushima-1 nuclear power plant into the sea, NHK TV channel reports.
⠀
Earlier, the Kyodo agency reported that on November 2, TEPSO began discharging the third batch of low-radioactive water that had been purified through the ALPS system. According to the company’s materials, the concentration of tritium in the water to be discharged was 55-77 becquerels per liter, which is significantly less than the established norm of 1,500 becquerels per liter.

“The Tokyo Electric Power Company (TERCO) announced the completion of the third stage of discharge of treated water accumulated at the Fukushima-1 nuclear power plant into the sea, which began on November 2,” the channel writes.
⠀
It is noted that the completion of the discharge did not entail any problems, and about 7.8 thousand tons of purified water contained in 10 reservoirs were discharged as planned.
⠀
On August 24, the TEPCO company began discharging water into the ocean, which had previously served to cool damaged reactors, and then was purified in the ALPS system. The system allows you to clean it from 62 types of radionuclides, with the exception of tritium. This water is stored in giant tanks on the station premises. To date, almost 90% of their volume of 1.37 million tons has been filled.
⠀
The total volume of water released from the emergency Fukushima-1 nuclear power plant in Japan during the 2023 fiscal year, which ends on March 31, 2024, will be 31.2 thousand tons with a radioactive tritium concentration of 5 trillion becquerels.
⠀
Despite claims from TEPCO and the Japanese authorities that the release of water does not pose a threat to the environment or humans, China and a number of other countries have sharply criticized such actions. In particular, the PRC banned the import of all Japanese marine products and strengthened customs controls on other products from Japan.
