PWR廃止措置における炉内サンプリング工事について
概要
Mihama Unit 1 & 2 are the first decommissioned nuclear power plants in the Japanese PWR (Pressurized Water Reactor). Internal reactor vessel sampling in PWR has never been conducted in Japan before. Mihama Unit 1 & 2 is the first one in the Japanese PWR. Usually, radioactive concentration on nuclear power plant is estimated based on operation history. Decommissioned nuclear power plants are demanded verification between estimation of radioactive concentration and measured result. This dissertation is describing about summary and result of internal reactor vessel sampling construction.
