Abstract

Abstract

This paper describes the fatigue crack propagation analysis and fast fracture mechanics analysis for the flaw in the outlet nozzle of Reactor Pressure Vessel（RPV） in Daya-bay Nuclear Power Station, using fracture mechanics analysis method. The calculation result is evaluated by the code, and it indicates there is no risk in outlet nozzle with the flaw.
