Radioactive leak from a nuclear reactor in Japan

According to the Kyodo agency, the operator of the power plant is Tohoku Electric Power Co. In the statement made by the company, it was stated that a water leak was detected in reactor number 2 of the Onagawa Nuclear Power Plant in Miyagi province.

In the statement, the investigation initiated after the water level in the discharge pit had risen since July revealed that a malfunction in a valve caused the leak.

In the statement, it was stated that a "small amount" of radioactive material was detected in the leaked water, and that no abnormal radiation level was measured in the environment.

In the statement, it was emphasized that it is estimated that approximately 200 liters of water leaked per hour due to the malfunction in reactor number 2 of the Onagawa Nuclear Power Plant, and that the reactor will be shut down to inspect and replace the parts.

Preparations will last 10 days

In addition, it was shared in the statement that preparations for inspection, repair and restarting of the reactor will take approximately 10 days.

The 9-magnitude earthquake that occurred in Japan on March 11, 2011 and the subsequent tsunami caused a radioactive leak at the Fukushima Dai-ichi Nuclear Power Plant. Tens of thousands of people living in the region had to leave their homes after the leak.

The Onagawa Nuclear Power Plant, north of the Fukushima Dai-i Nuclear Power Plant, was also closed for security reasons. Reactor number 2 of the plant, which received a working permit in February 2020 within the scope of the security measures introduced by the Japanese government regarding nuclear power plant operations, started operating in 2024.
