Abstract

Abstract

Best estimate plus uncertainty method could be used to eliminate the over-conservatism in the current method and gain more safety margin.In the current paper,uncertainty method which has considered the effect of the initial conditions,boundary conditions,and model uncertainties has been developed based on the best estimate code RELAP5.This method was used to analyze the NEPTUN reflood experiment.The results showed that the new method was reasonable.
