We found minute steam leak at about 7:00 pm on March 30, 2018 from an air-bleeder pipe of deaerator in secondary system of Genkai Nuclear Power Station Unit No.3 (Pressurized Water Reactor, 1,180MW output), which has been in periodic inspection. The plant, which restarted to generate electricity on March 25, 2018, had been in adjustment operation with output of 75%.

　As a result, we decided to stop generating by dropping a load from output of 75% and to investigate the plant as a precaution.
　There is no effect of radiation to the environment on this matter.

　We will carefully continue to carry out each process, putting utmost priority to safety.
