TEPCO's Fukushima Daiichi Nuclear Power Station has reduced the amount of contaminated water generated in the last year to less than the target, so the tank for storing contaminated water, which had been around next summer, is full. It has revealed that the time will be extended.
At the Fukushima Daiichi Nuclear Power Plant, contaminated water containing radioactive substances is generated by mixing the cooled water of the melted down nuclear fuel with the groundwater and rainwater that have flowed into the basement of the building.
Regarding this, TEPCO has set a goal of reducing the daily generation to about 150 tons by last year, and measures such as installing a cover to prevent the inflow of rainwater on the roof of the Unit 3 turbine building that was punctured by the hydrogen explosion. I have been advancing.
As a result, the amount of contaminated water generated in the last year was reduced to 140 tons per day, which is less than the target.
The water after treating the contaminated water with a purification facility is stored in a tank on the premises with radioactive substances such as tritium remaining, and TEPCO said that the tank will be full by the summer of next year. The country is considering a disposal method.
At the press conference, Akira Ono, the representative of TEPCO's Fukushima Daiichi Decommissioning Promotion Company, commented on the outlook for when the tanks would be full in response to the reduction in the amount of contaminated water generated. There is no doubt that it will be behind the summer of 2022 that we have shown so far. We are reviewing our forecasts. "
