Abstract

Abstract

The containment ILRT for 10 years occupies the critical path of refueling for about 100 hours. 94 nuclear power units in the United States have extended the containment ILRT cycle to 15 years based on containment performance evaluation. This paper introduces the performance evaluation requirements of the relevant containment in the United States in detail, and analyzes the extension of the ILRT cycle by the CPR1000 unit, and the availability of historical test data and inspection data. Taking a CPR1000 demonstration unit as an example, the risk after prolonging the safety test of the containment is calculated, and the risk increment is very small. The results show that the CPR1000 unit basically is with the conditions to extend the test period of the containment seal.
