Kashiwazaki-Kariwa Nuclear Plant Shuts Down Reactor After Malfunction
Tokyo Electric Power Company (TEPCO) has halted operations and initiated a shutdown of the No. 6 reactor at the Kashiwazaki-Kariwa nuclear power plant. This action follows the detection of a malfunction in the control rod monitoring system just one day after the reactor was restarted.
According to a company statement, an alarm was triggered during the control rod withdrawal process. Attempts to resolve the issue by replacing electrical components within the control panel were unsuccessful, prompting a full investigation. TEPCO has assured the public that the plant remains stable and there is no evidence of radioactive leakage.
The shutdown is a setback for TEPCO, which had only recently brought the reactor back online after a 15-year hiatus following the 2011 Fukushima disaster. The Kashiwazaki-Kariwa plant, the world’s largest nuclear power station by capacity, received approval to restart its no. 6 reactor in December after passing safety reviews in 2017. Previous delays were due to security concerns regarding potential terrorist attacks.
The restart of Kashiwazaki-Kariwa is a key component of Japan’s energy strategy, aiming to increase nuclear power generation to meet energy demands and reduce carbon emissions. This incident marks the first time TEPCO has successfully restarted a nuclear plant since the Fukushima catastrophe, making the current shutdown notably sensitive.
TEPCO has stated it will announce the findings of its investigation as soon as they are available.
