The News That Matters about the Nuclear Industry Fukushima Chernobyl Mayak Three Mile Island Atomic Testing Radiation Isotope

Protective sheet positioned at damaged reactor


June 12, 2020

The operator of the crippled Fukushima Daiichi nuclear plant has released footage showing part of the time-consuming steps needed to remove nuclear fuel from a pool at its No.1 reactor.

In the video, workers used remote-controlled tools to place a wide sheet over the surface of the pool. The radiation level there remains high.

Tokyo Electric Power Company has been engaged in removing debris from the upper part of the reactor building where the pool is located. The debris was caused by an explosion during the 2011 nuclear accident.

The sheet is meant to protect the pool and 392 nuclear fuel assemblies still inside from further damage that could result from the possible falling of debris or large machinery.

The six-by-eleven meter sheet is inflatable to a thickness of 50 centimeters. It will be filled with cement to increase its strength.

The operator plans to begin clearing the debris from around the pool by the end of the month, as soon as the sheet’s cement has solidified.

The operator plans to start removing the fuel from the pool of the No.1 reactor in fiscal 2027. Similar work at the No.2 reactor will start in fiscal 2024. Fuel removal from the pool at the No.3 reactor will be completed by fiscal 2020. The removal work is finished at the No.4 reactor.
