| Scenario Event Summary NRC SCENARIO 2 The Crew will take the watch with the plant at 100% Rated Thermal Power (RTP) with RCIC isolated last shift due to a steam leak on the F045 valve. . Direction will be to reduce power to 93%
| |
| using Reactor Recirc flow to permit performance of the Main Turbine Control Valve PMT.
| |
| The Unit Supervisor (US) will direct the At the Controls (ATC) operator to reduce power to 93%
| |
| using Reactor Recirc flow, IAW IOI-0003, Attachment 3, Power Maneuvering (event 1).
| |
| When Reactor Power is ~ 93%, the US will direct the Balance of Plant (BOP) operator to perform partial SVI-N31- T1153, Main Turbine Control Valve Exercise Test for PMT of TCV #1 (event 2).
| |
| When SVI-N31-T1153 is complete, or at the Lead Evaluator discretion, fail APRM H at 50%. The crew will identify the failed APRM H and request the status of APRM D calibration (completed SAT).
| |
| The US will declare APRM D Operable and direct the ATC operator to return APRM D to service and bypass APRM H IAW SOI-C51, then reset the 1/2 scram IAW SOI-C71 (event 3).
| |
| At the Lead Evaluators cue, the SEISMIC ALARM P969 annunciator alarm(s) will be received (along with an announcement to the crew that ground motion was felt), and the US will enter ONI-D51, Earthquake. When the US determines that OBE levels have been exceeded, the BOP operator is directed to start all ESW loops IAW SOI-P45/49, and the ATC operator to commence power reduction IAW IOI-0003/4 (event 4).
| |
| At the Lead Evaluators cue, initiate the Condensate Storage Tank level instrument failure. The BOP operator announces receipt of the HPCS SUPR POOL SUCT VLV OPEN CST/SUPR PL LVL alarm and that the CST Suction Valve, E22-F001 failed to shut. The BOP will close F001 valve. The US will declare HPCS CST instrument Inoperable and enter TS 3.3.5.1 Cond A1 immediately then Cond D.2.2 (in 24 hours). (event 5).
| |
| At the Lead Evaluators cue, provide an announcement to the crew that (for the 2nd time) ground motion was felt. When the ATC operator reports a trip of the B RFPT due to low oil pressure, the US will enter ONI- C34, and ONI-C51.and direct the crew to take actions to secure the B RFPT Turning Gear IAW SOI-N27 (event 6).
| |
| Following completion of the ONI- C34 required actions, or at the Lead Evaluators cue, when the BOP reports rising DW Temperature and Pressure, and multiple annunciator alarms that indicate leakage in the DW, the US will enter EOP-02 on rising DW pressure/temperature and ONI-C71-1, Reactor Scram, direct the ATC operator to insert a Manual reactor scram, and enter EOP-01 as necessary (event 7).
| |
| At the Lead Evaluators cue, provide an announcement to the crew that ground motion was felt again (for the 3rd time). The US will re-enter ONI-D51, and when the BOP operator reports receipt of annunciator alarm TURBINE BLDG BASEMENT WATER LEVEL HIGH, the US will direct the BOP operator to trip all Circ Water pumps and will enter ONI-N62, Loss of Condenser Vacuum. The US enters EOP-02, Primary Containment Control, on high Drywell pressure (from Event 7). (event 8).
| |
| At the Lead Evaluators cue, initiate the inadvertent ADS initiation. The crew will analyze plant conditions and determine initiation of ADS is inadvertent. The US will Enter ONI-E12-1, Inadvertent Initiation Of ECCS/RCIC and perform Immediate Actions of delaying then inhibiting ADS. (event 9).
| |
| | |
| Scenario Event Summary At the Lead Evaluators discretion, and once the crew has successfully completed the , controlled cooldown and restored RPV level control using low pressure systems, the scenario may be terminated.
