Abstract: Aiming at the defect without mechanical filter module in the hot well of the condenser in a nuclear power station, some improvement process were proposed base on the comprehensive analysis of the above defect. The final improvement program to add the mechanical filter and mechanical filter cover of hydrophobic filter standpipe were accomplished by applicability of each improvement program and actually condition of the site, meanwhile the optimization program for followed unit were recommended. The results indicate that the defect about lace of mechanical filter module in the hot well can be solved thoroughly, which ensure the water quality and safety operation of the condensate pump in the process of commissioning and normal operation of the unit.
