大飯４号機、定期検査で停止　関電、３年半ぶり原発稼働ゼロ

　関西電力で唯一稼働していた大飯原発４号機（福井県おおい町）が３日、定期検査のため稼働を停止した。１２月下旬に高浜原発３号機（同県高浜町）が再稼働するまでの約１カ月半、関電で稼働中の原発はゼロになる。関電の原発がすべて停止するのは２０１７年５月以来、約３年半ぶり。
　大飯４号機の定期検査では、設備の保全対策として配管の超音波検査や交換を実施。燃料の取り換え作業も行う。営業運転は来年２月中旬に再開する予定。（2020/11/03-13:36）

The No. 4 reactor of Kansai Electric Power Co.'s Oi nuclear power plant in western Japan was suspended on Tuesday for periodic inspections, marking the first time since May 2017 for all of its reactors to go offline.
   The company will have no active reactor until the No. 3 reactor of its Takahama plant is brought back online in late December.
   In the checkup of the Oi No. 4 reactor, ultrasound examinations and replacement of piping will be conducted, while fuel will be replaced.
   The reactor is scheduled to resume commercial operations in mid-February 2021.
   According to Kansai Electric, an active reactor at Oi pushes up the company's earnings by 3.5 billion yen per month, while one at Takahama raises its monthly earnings by 2.5 billion yen. Both plants are located in Fukui Prefecture.
