Osaka, Aug. 2 (Jiji Press)–Kansai Electric Power Co. <9503> said Monday that it will restart the No. 1 reactor at its Takahama nuclear power plant in western Japan, which is over 40 years old, in June 2023.

While the company had transported nuclear fuel assemblies into the reactor and confirmed the safety of devices in May this year, Kansai Electric passed over the planned restart of the nuclear reactor in the town of Takahama, Fukui Prefecture, as construction work for antiterror purposes was not finished by the deadline.

The construction work to build an antiterrorism facility will be completed in May 2023.

The Takahama plant’s No. 2 reactor, which was also built more than 40 years ago, will be brought back online in July 2023.

Antiterrorism facilities at the two reactors are expected to cost Kansai Electric around 170 billion yen.

Once the reactors are restarted, Kansai Electric expects to see its monthly earnings pushed up by some 2.5 billion yen per reactor.

An antiterrorism facility at the No. 3 reactor at Kansai Electric’s Mihama nuclear power station, also in Fukui, which became the first nuclear reactor over 40 years old to be reactivated in Japan in June this year, will be completed in September next year.

As such construction work will not be finished by the set deadline of October this year, Kansai Electric will halt operations temporarily at the No. 3 reactor. It will be restarted in October next year, after the facility has been completed.

An antiterrorism facility at the No. 3 reactor at the company’s Oi plant, also in Fukui, which is currently in operation, will be completed in December 2022, a four-month delay from the deadline.

A similar facility at the Oi No. 4 reactor will be completed by the deadline of August next year.
