Background
Unit 1 of the Tokai nuclear power plant was Japan's first commercial power reactor. It was imported from the United Kingdom and began operating in July. 1966. It was retired in March 1998. Unit 2 of the Tokai nuclear power plant began operating in March 1978. As part of the nationwide reactor shutdown in response to the 2011 Fukushima disaster, the unit suspended operation.[5]
In May 2014, JAPC submitted an application to the Nuclear Regulation Authority (NRA) to restart Tokai 2. In November 2017, the company applied to extend its license to operate the unit by 20 years. The request was granted a year later. JAPC submitted a basic design plan in September 2018 and a detailed design plan the following October. The 20 year license extension required work on safety measures to be completed in September 2024. In October 2023, JAPC discovered multiple gaps near the seawall’s steel reinforcement pillars and suspended construction on the unit.[6]
