Abstract

Abstract

In this paper, cause analysis of reactor coolant pump motor oil leakage is performed, and suggested solutions are presented. Based on the CFD analysis result, supplementary baffle and seal can reduce the fan effect on the lower guide bearing caused by flywheel, and the supplementary condensate device and oil recycling pipe can recover the possible oil and oil mist leakage. The solutions mentioned above can reduce the oil leakage and oil mist leakage of this motor.
