[3I16] Evaluation of cooling capability of isolation condenser under accident conditions

(4)Evaluation of effect of noncondensable gas

*Masayoshi Mori¹, Yasunori Yamamoto¹ (1. Hokkaido University)

Keywords:isolation condenser, core cooling, high pressure experiment, non-condensable gas

Experiments were conducted by injecting helium into a device simulating an isolation condenser, and experimental data for evaluating the effect of noncondensable gas on cooling performance was acquired. As a result of the experiment, a decrease in the steam flow rate was confirmed.
