Concern over the sudden shutdown of the Onagawa nuclear reactor in Japan

The nuclear reactor number two of the Onagawa power plant in Japan, which restarted less than a week ago after a 13-year hiatus, was forced to an emergency shutdown due to a technical problem. This happens while this reactor was supposed to be connected to the electricity grid soon and start commercial electricity production.

According to Tekna Technology Media Scientific News Department, according to reports, the main problem has been identified in a measuring instrument. In order to thoroughly investigate the cause of the problem and prevent any possible danger, it was decided to stop the reactor immediately. The operating company of the power plant has emphasized that no leakage of radioactive materials has been reported so far and the safety of the employees and residents of the area is a priority.

The Onagawa power plant was shut down in 2011 due to safety concerns after Japan’s devastating earthquake and tsunami. This plant was able to withstand this natural disaster due to its strong structure, while the nearby Fukushima plant suffered serious damage.

After the Fukushima accident, Japan decided to shut down all its nuclear power plants. But with the passage of time and according to the goals of reducing greenhouse gas emissions and achieving zero carbon by 2050, this country has gradually restarted some of its nuclear power plants. The sudden shutdown of the Onagawa reactor shows that restarting nuclear power plants after a long shutdown is accompanied by numerous technical and safety challenges. This could also affect public confidence in nuclear power and slow the return to nuclear power in Japan.

This event once again reminds us of the importance of strict compliance with safety standards in the nuclear industry. Any technical problem in a nuclear power plant can have very serious consequences, and for this reason, careful monitoring of the operation of these power plants and periodic inspections are of particular importance.
