Fukushima Nuclear Power Plant "cold shutdown" is difficult to schedule

Japan's Tokyo Electric Power Company said on the 17th that the high-radiation sewage purification operation at the Fukushima Daiichi Nuclear Power Plant has been progressing slowly, possibly delaying the “cold shutdown” of nuclear power plants.

A Tokyo Electric Power Company spokesperson told Reuters on the 17th that the circulating purification system used to treat high-radiation sewage at the Fukushima Daiichi nuclear power plant failed several times to suspend operation, delaying the purification of high-radiation sewage, which may cause nuclear power plants to fail to realize on schedule.” Cold shutdown."

The so-called "cold shutdown" refers to a safe state in which a nuclear reactor stops operating and is cooled down to room temperature. According to the timetable announced by Tepco, the Fukushima Daiichi NPP is scheduled to achieve this goal in January next year.

On the 17th, Dongfang said that as of the 9th of this month, only about 42,000 tons of high-radiation sewage was subjected to purification operations, and about 120,000 tons remained in the plant buildings and other places. The target set by Dongdian was to complete the purification of 200,000 tons of radioactive sewage before the end of the year.

On the 17th, the Governor of Hokkaido, Japan, Takahashi Harumi returned to commercial operation of the No. 3 unit of the moored nuclear power plant operated by Hokkaido Electric Power Co., Ltd., and “turned on the green light”.

Following the leakage of a large quantity of radioactive material at the Fukushima Daiichi nuclear power plant, the Japanese nuclear power plant project was under pressure from all parties. Thirty-five of the total of 54 nuclear reactors were affected by the quake or were suspended due to regular inspections.
