2. FASV False Closing of SG 2 (PSAR page 1998 – 204)
PCTRAN is run by disabling the pressurizer spray and heaters, and than closing the MSIV at the left hand “A” side single SG. Five seconds later the A-side MCP is tripped. The reactor is automatically tripped at about 15 seconds on high SG pressure of 78 bar (slightly earlier than the PSAR case). No other actions are taken in conduction this study.
