Study on the Emptying and Maintenance Work for the Refueling Water Tank of Qinshan No.2 Nuclear Power Plant
The emptying and maintenance work for the refueling water tank was the main task during the over-haul of the M310 unit,which took a long time and had unclear work window arrangements.During the evacua-tion work,the spent fuel pool lost cooling,resulting in high pressure for wastewater reception and treatment.During the maintenance work,the spent fuel pool lost cooling and backup.In view of the above problems,the paper finally determines the emptying maintenance window of the refueling water tank through the comparative analysis of the actual data,and parallels the work of each stage during the emptying maintenance with the work of other main lines,so as to ensure that the emptying maintenance of the refueling water tank does not occupy the main line alone and save the overhaul period.
