高浜１号機、５０年超運転へ　規制委に変更認可申請―関電

　関西電力は２日、来年１１月で運転開始５０年を迎える高浜原発１号機（福井県高浜町）について、同６０年目まで１０年間の点検、保全計画などを盛り込んだ保安規定の変更を原子力規制委員会に申請した。認可されれば、来年１１月以降も運転継続が可能になる。
　１９７４年１１月に運転を開始した高浜１号機は、国内で稼働する原発で最古。規制委から６０年までの運転期間延長認可を受けているが、５０年目を迎える前に現時点での健全性評価や、点検計画などを提出し、認可を受ける必要がある。（2023/11/02-19:14）

Kansai Electric Power Co. applied to Japan's Nuclear Regulation Authority on Thursday to continue operating the No. 1 reactor at its Takahama nuclear power plant after the reactor reaches 50 years of operation in November 2024.
   The power utility submitted changes to the plant's safety regulations, including plans for the inspection and maintenance of the reactor for the next 10 years.
   The No. 1 reactor at the Takahama plant in Fukui Prefecture, central Japan, is the oldest active reactor in Japan. It was commissioned in November 1974.
   The NRA has approved an extension of the reactor's operating life to 60 years, but Kansai Electric must obtain the regulator's approval of the submitted documents, including soundness assessments, before the reactor reaches its 50th anniversary.
   Kansai Electric conducted soundness assessments on about 4,000 pieces of equipment, and determined that it can ensure the soundness of the equipment until the 60th anniversary by implementing four additional maintenance measures, including replacing the reactor's internal structures and inspecting parts that were found to have deteriorated at other plants.
