NRA “Radiation dose is too high in reactor4 spent fuel pool area” → Tepco covered lead plate over the crane

Tepco is removing the fuel assemblies from reactor4 pool. NRA (Nuclear Regulation Authority) commented the radiation dose in pool area is too high, they ordered Tepco to take measures to reduce the radiation level.
Tepco was stating the pool water shields radiation from the fuel assemblies. However now that the pool water is highly contaminated, the workers also need to protect themselves from the increased radiation dose by the pool water.

The workers check inside of the water from above the refueling crane moving above the water. Tepco put lead plate over the crane to reduce the radiation level.
