Abstract

Abstract

The CPR1000 Passive Residual Heat Removal（PRHR） System were investigated using RE-LAP5/MOD3.4 under the condition of Station Blackout（SBO）.The flow instability of SG secondary side was affected by the arrangement of the air-cooled heat exchanger and the height of the cooling tower.The calculation results showed that the horizontal layout of the air-cooled heat exchanger could reduce the flow instability obviously,and the instability decreased with the increase of the cooling tower.The results also showed that the PRHR of CPR1000 could remove the core residual heat after the SBO to ensure the safety of the reactor.
