2020 NRC Exam Scenario 4 D-1 Rev 1 Critical Task Safety Significance Cueing Measurable Performance Indicator Performance Feedback
CT-1: Isolate Most Affected Steam Generator This task is satisfied by manually closing Main Steam Isolation valve #2, Main Feedwater Isolation Valve #2, and MS-401B after RCS THOT has reduced below 520°F and prior to exiting the step (Step 17) to isolate the most affected Steam generator in OP-902-007, Steam Generator Tube Rupture Recover This task becomes applicable once the SGTR has commence (OP-902-007, 17)
A ruptured SG presents a flowpath for radioactive releas Isolating the SG will terminate the release lowering the dose to plant personnel and the publi RCS THOT < 520°F is based on Emergency Operating Procedure standar Isolating the SG at a temperature higher than this value may complicate the response later in the scenario by not allowing a full depressurization of the RCS to below the lowest Main Steam Safety Valve setpoin This higher RCS pressure would allow the RCS to continue to flow into the affected SG ultimately raising the SG level and pressure to the safety valve setpoint and cause a release that could have been prevente OPS management Standard documented in TM-OP-100-0 (TM-OP-100-03, CT-14)
