[1G03] Experimental evaluation of effect of non-condensable gas on cooling performance of isolation condenser

Keywords:natural circulation, non-condensable gas, condensation heat transfer, isolation condenser

Experiments simulating isolation condenser were performed to evaluate effect of non-condensable inflow on cooling performance of isolation condenser. Retention of helium occurred at the upper part of the loop, which led to increment of pressure drop.
