Abstract: As an important cooling equipment of nuclear power plants, the tightness of condenser is directly related to the safe operation of nuclear power plants. In this paper, the real working conditions of the condenser(the vacuum side is 7500Pa, the pressure side is 110kPa) are simulated, an experimental system is built based on quadrupole mass spectrometer, and the leakage rates of three gas media including helium, air and SF6 are studied under different magnitudes of leakage holes(helium equivalent leakage rate is 10-7~10-1Pa·m3/s). The results show that under condenser conditions, the leakage rate of the gas medium within the measured magnitude has nothing to do with the type of medium, but only with the nominal leakage rate.

Key words: condenser, quadrupole mass spectrometer, sulfur hexafluoride, leak detection
