Abstract

Abstract

Because of the origin design for control logic of entrance isolation valve in RRA system was not conform to the single failure criterion, the improvement scheme, which would be added two sets of pressure transmitter, has been raised. The effect of RRA system and the damage of reactor core have been evaluated through quantitative calculation about the scheme of the modification.
