Abstract

Abstract

A Risk-informed Safety Margin Characterization (RISMC) analysis method based on RAVEN software and Monte Carlo (MC) sampling is introduced in the paper. The influence of thermal parameters and personnel action time uncertainty on the safety margin of steam generator tube rupture (SGTR) accident is comprehensively analyzed. The calculation results are compared with the traditional safety assessment methods. Aiming at the key influence parameters of the accident, based on MC sampling to quantify the key parameter samples affecting the safety margin, the system simulation model of SGTR accident is established by RELAP5 program, coupled calculation and analysis are carried out by RAVEN software. And finally the probabilistic safety margin of SGTR accident and its sensitivity to various influencing parameters are obtained under the condition of auxiliary water supply system failure.
