Abstract: The low concentrated boric acid storage tank (LC-BAST) is a major equipment of boric solution storage system for WWER1000 PWR. It is used for the storage of the primary-loop boric solution. The maintenance of the tank causes many issues of radiation protection. In this paper, the practice and methods of occupational exposure control in the maintenance of the tank are introduced, mainly including the radiation risk analysis and the practice of radiation protection,and evaluating the protective effect during the maintenance .

Key words: low concentration boric acid solution tank, maintenance, radiation protection
