Japan’s nuclear watchdog, the Nuclear Regulation Authority (NRA), has removed the operational ban imposed on Tokyo Electric Power’s (Tepco) Kashiwazaki-Kariwa power plant, enabling the facility to progress towards a potential restart.
The Kashiwazaki-Kariwa plant, known as the world’s largest atomic power facility with an 8,212-megawatt capacity, has been offline since the aftermath of the Fukushima disaster in 2011, which led to the closure of Japan’s nuclear power plants at that time.
In 2021, the NRA prohibited Tepco from operating the plant due to safety violations, such as inadequate nuclear material protection and unauthorized access to sensitive areas by staff.
However, citing enhancements in safety management systems, the NRA has lifted the corrective action order that had hindered Tepco from transporting new uranium fuel and loading fuel rods into the reactors, effectively blocking the plant’s restart.
For Tepco, the prospect of resuming operations at the Kashiwazaki-Kariwa plant signifies a potential reduction in operational costs. Nevertheless, the restart still hinges on securing local consent in Niigata prefecture, situated on the Sea of Japan coast.
Following an on-site inspection and discussions with Tepco’s president, the NRA’s recent decision to lift the ban saw a significant rise in Tepco’s stock value, indicating investor optimism about the plant’s future.
