概要
Large amount of sea water intruded Reactor Buildings including controlled area of Fukushima-Daini Nuclear Power Plant (NPP) at the Tsunami disaster 11th May 2011 and the sea water was contaminated by some radioactive substances. Although the concentration of the radioactive substances was low enough to meet the criteria of technical specification for discharge to the sea、we decided to decontaminate it under the limit of the detection for more safe. Then the result of the discussion with local government and some related parties it was decided to separate completely to the radioactive substances、 pure water and salt. The safety handling and separate technic are described in this paper.
