The Sendai-1 nuclear reactor in southwestern Japan returned to commercial operation at 16:00 local time yesterday, the first reactor to resume full operation in Japan since the March 2011 Fukushima-Daiichi accident.
Operator Kyushu Electric Power Company said commercial operation began after a comprehensive pre-service inspection was completed. The 846-megawatt pressurised water reactor unit, which first began commercial operation in July 1984, was restarted on 11 August. All of Japan’s 48 commercial reactor units were shut down for safety checks and upgrades following the Fukushima-Daiichi accident. Five reactors have now been earmarked for permanent shutdown, bringing the number of potentially operational commercial units to 43.
