Safety Upgrades In Japan Deter Restarts

A report from Asahi Shimbun, one of Japan's national newspapers, said that the Kyushu Electric Power Company is closing down operations of the Sendai Unit 2 nuclear power plant for failure to complete a remote-operations safety measure required by the country’s nuclear regulator.

KySendai NPPushu Electric missed the deadline for the new regulation that was put in place after the Fukushima Daiichi NPP disaster of March 2011. The deadline for the safety improvements, meant to allow for operations of the plant from an offsite location, was May 21.

According to Nuclear Engineering International, the safety measure is expected to be completed within five years after the design of the upgrades have been approved.

 Kyushu Electric’s Sendai Unit 1 reactor met with a similar fate with a forced shutdown in the middle of March 2020. In addition, Kansai Electric Power Company has also been forced so delay operations schedules due to encroaching deadlines on incomplete safety improvements.

Kansai announced in February that three Fukui Prefecture reactors – Takahama Units 1 and 2 and Mihama Unit 3 – would have their starts postponed in order to comply with the regulatory timetable. Media reports also indicated that restarts for Takahama Units 3 and 4 will be delayed f or similar reasons.
