Abstract

Abstract

Current standards such as ANSI/ANS56.8 and NB/T20018—2021 require the assumption of containment insulation for measuring the leakage rate of containment. The gas quality stability criteria in the standards will fail in the measurement of the leakage rate of non-adiabatic containment. In order to explore the sealing evaluation method of non-adiabatic containment, this study innovatively proposed a leakage rate stability criterion and completed experimental verification on the non-adiabatic scientific research containment at Langfang R&D Base of China Nuclear Power Engineering Co., Ltd. The results indicate that the new stability criterion for leakage rate can be used to measure the leakage rate of non-adiabatic containment. In addition, the test data of a certain nuclear power plant indicates that the new criterion can also be used for measuring the leakage rate of adiabatic containment, shortening the test time. The conclusion of this study can support the application of scientific research non-adiabatic containment to conduct leakage rate research and optimize the sealing test technology of nuclear power plant containment.
