The corroded holes were discovered when insulating material — that had been wrapped around the ducts — was removed during a check in December 2016 at the No. 2 reactor at the Shimane plant, which is operated by Chugoku Electric Power Co. The largest hole of the 19 was found to be approximately 30 centimeters by 100 centimeters in size.

Corroded holes in ducts present a threat as there is a chance that radioactive material could flow into the central control room via the holes during an accident — thereby exposing power plant staff to radiation.
