Abstract:
Aiming at the risk of internal and external leakage for the damper in the nuclear power plants, some design measures for solving the internal and external leakage have been proposed. By the leakage tests before and after the seismic test, the seal design rationality of the damper is demonstrated. Based on the analysis of the difference between the internal and external leakage test data of two set of the dampers, the results are indicated that the leakage of the above two sets of the dampers is in compliance with the technical specification.
