Kashiwazaki-Kariwa Nuclear Power Plant

The Kashiwazaki-Kariwa Nuclear Power Plant, operated by Tokyo Electric Power Company (Tepco), is the world's largest nuclear power plant by installed capacity. It's located in Niigata prefecture, Japan, and was idled following the 2011 Fukushima disaster. Recently, the plant has been newsworthy due to efforts to restart its reactors. Reactor number six was restarted after nearly 15 years, but operations were quickly suspended due to an alarm during start-up procedures. The restart's timing is uncertain. Adding to the controversy, an employee of Japan's Nuclear Regulation Authority (NRA) lost a phone containing confidential data related to nuclear security at the plant during a personal trip to China, raising concerns about potential data leaks. These events highlight the challenges and sensitivities surrounding Japan's efforts to revive its nuclear power program in the wake of Fukushima.
