Research of Equipment Corrosion in Spent Fuel Reprocessing Plant of Japan and Enlightenment

Abstract

In severe operating conditions of spent fuel reprocessing plants, such as strong acid and high temperature, equipment corrosion problems are common. The corrosion problems/incidents in Japanese reprocessing plants and some relevant experimental research, evaluation and investigation work carried out by Japanese institutions and scholars were summarized in this paper. The related research results and experience from Japan will provide our country with some reference and technical basis for the design and manufacture, life prediction, preventive maintenance of key equipment, periodic safety evaluation of reprocessing facilities, etc.
