In nuclear power plants, it is needed to keep the water quality of reactors or steam generators extremely clean from the viewpoints of the reduction of the radiation exposure and maintenance of the reliability of plant materials. In order to meet these requirements, the role of the condensate demineralizers and the ion exchange resins are very important. Furthermore, the requirements of water quality have been upgrading compared to them in 1970's
In these 4 reports, the performances and these improvements of condensate demineralizers and ion exchange resins are introduced. On this third report, the crud removal performance by ion exchange resins and its improvement are reported.

KEYWORDS:ion exchange resins, condensate demineralizers, crud removal, water retention capacity, surface area

The Radioactive Soil Sorting Equipment.
FAPIG No. 195 pp. 8 to 12 (2018)

In the process of restoring the Fukushima Dai-ichi Nuclear Power Station (Tokyo Electric Power Company Holdings, Inc.) accident in the Great East Japan Earthquake, a large amount of soil, grass, trees, branches, mud in gutter and other wastes are temporarily stored in Fukushima Prefecture as a result of decontamination activities. In order to safely and intensively manage and store the mentioned soil until final disposal, it is required, when they are received, to safely sort a large amount of them into type I (8000 Bq/kg or less) and type II (above 8000 Bq/kg) depending on the radioactivity concentration.
Fuji Electric Co., Ltd. and Shimizu Corporation have jointly developed the radioactive soil sorting equipment using the continuous batch system. In this paper, therefore, we introduce its main specifications and performance.

Kawasaki Heavy Industries (KHI) is progressing labor-saving for plant construction by using 3D modelling and 3D measurement tools. This report introduces how 3D modelling and measurement tools are able to be used in each process of plant construction from designing to test operation and shows the prospect for future construction.
