概要

Mihama Unit 1 & 2 are the first decommissioned nuclear power plants in the Japanese PWR (Pressurized Water Reactor). FSD (Full System Decontamination) in PWR has never been conducted in Japan before. FSD in Mihama Unit 1 & 2 is the first one in the Japanese PWR. On the other hand, heat transfer tubes of steam generator are made of nickel alloy 690. Chemical decontamination for nickel alloy 690 has never been conducted in the world. As the result, the target which DF (decontamination factor) is over 30 is achieved in FSD of Mihama Unit 1 & 2. DF in the heat transfer tubes of steam generator made of nickel alloy 690 is well over 30.
