Japan's 40-year nuclear power unit operation extended for 20 years

Japan's Nuclear Regulation Commission announced on the 5th that the No.
3 unit of the Kansai Electric Power Company's Mihama Nuclear Power Plant meets the new nuclear power plant safety standards, which means that the nuclear power unit can continue to be used until 2036
.

Unit 3 of the Mihama Nuclear Power Plant in Fukui Prefecture was officially put into operation in December 1976 and is about to reach the standard
of 40 years of retirement.
According to Japan's Kyodo News Agency, Japan's Nuclear Regulation Commission held a regular meeting on the 5th to discuss the relevant review, and found that the Mihama Nuclear Power Plant Unit 3 met the new nuclear power plant safety standards
.

However, in order to continue to operate, Unit 3 of the Mihama Nuclear Power Plant will need to undergo large-scale additional construction and transformation, and the actual "overdue service" will not be until four years later
.

After the Fukushima nuclear accident in 2011, Japan implemented new safety standards for nuclear power plants, which set the general operating life of nuclear power plants at 40 years
.
However, with the review and approval of Japan's Nuclear Regulation Commission, an extension of the operating period of 20 years may be allowed
.

In June this year, two nuclear power units at the Kansai Electric Power Company's Takahama Nuclear Power Plant were approved to continue their service for 20 years
.
This is the third "old" nuclear power unit approved by Japan to continue operation after 40 years of operation
.
Japanese media say that the principle of 40 years of operation of Japan's nuclear power plants has gradually become useless
.

On August 9, 2004, a steam leak occurred in the turbine room of the No.
3 reactor of the Mihama Nuclear Power Plant, killing five people and injuring six, the deadliest nuclear power plant accident
in Japan before the Fukushima nuclear accident.
