Calvert Op Test No.: 1 Examiners: Operators: SRO RO CRO To evaluate the applicant's ability to conduct a unit power reduction, to implement the ARMs, OIs, AOPs, as Objectives: appropriate, for malfunctioning systems and/or controls including a failure of PRZR level control channel (llOX) which causes a broken shaft on 12 Charging Pp, a failed FRV Controller (1121) and a SGFP oil leak causing a rapid power reduction. A loss of 11 BA Pp occurs at the start of the downpower. The crew will be forced to trip the unit when the running SGFP trips. Two stuck CEAs require boration to meet reactivity but a loss of 11 4KV Bus will force the crew to EOP-8 for reactivity not being met. In EOP-8, boration will be restored via IPSI injection and 11 AFW Pp will trip resulting in a loss of feed. The crew can restore AFW by aligning 12 AFW Pp.

Initial Conditions: The plant is at 67% Power, MOC (IC-17) 11 Chg Pp is OOS 12 SGFP Pp is OOS.

RCS026_01 I RO About 3 minutes after the crew has taken the watch, PRZR level contr. (1 loX)

(low) fails low. The RO should acknowledge the alarm, inform the CRS and refer to the ARM. Level control should be shifted to channel Y and the OWC notified.

T.S. 3.3.10 should be entered.

2 CVCS003_02 C RO 12 Chg. Pp shaft breaks on start following 1lOX failure, however, the pump stops again when channel Y is selected. It is unlikely the crew will notice the failure here, but probably later during the downpower or boration to meet reactivity control in EOP-0. When discovered the crew is expected to attempt to ensure boration via another means and to contact the OWC for assistance.

3 FW018_02 I CRO Next, 12 SG FRV Controller (1121) fails. The CRO should acknowledge the (LO) alarm and inform the CRS. The CRS should direct the CRO to maintain SG level and implement AOP-3 G. The CRS should direct the CRO to place the controller switch in the Main Fail position. The CRS should direct the OWC to contact the System Engineer for assistance.

4 PNL OVR C CRO The CRO acknowledges the SGFP Conditioner Level Low Alarm, informs the (Conditioner R RO CRS and dispatches the TBO. Following the TBO report, a rapid downpower level low C RO will be initiated to take 11 SGFP off. (The crew may notice the charging pump alarm) N CRO malfunction at this time.) The OWC should be contacted for assistance and CVCS014_01 notifications. As the power reduction to take 11 SGFP off is begun, 11 BAPp FW004_01 trips off when started. The RO will either use 12 BA Pp or gravity feed from the BASTs. At =50% power, 11 SGFP trips. The CRS should order the unit tripped due to loss of feed. EOP-0 is implemented, the RO notes 2 stuck CEAs and commences boration.

5 4KVOO1_01 M ALL After the RO reports on Pressure and Inventory, a loss of 11 4KV Bus occurs (may refer to AOP-71). The CRS orders a reassessment of safety functions. The RO should determine reactivity is no longer being met due to no charging and direct the TBO to align 13 Chg. Pp to 14 bus. With the TBO being unsuccessful the CRS will enter EOP-8 for failure to meet reactivity.

6 AFW001_01 M ALL EOP-8 is entered and the selected Success Paths begun. Boration is restored via EPSI injection. While working to establish boration, 11 AFW Pp trips the CRS or CRO should direct the TBO to investigate and align 12 AFW Pp. After AFW has been restored and boration, established, the scenario can be terminated.

SCENARIO 3 OVERVIEW The candidates will take the shift at =67% power.

About 3 minutes after the crew has taken the watch, PRZR level contr. (11OX) fails low. The RO should acknowledge the alarm, inform the CRS and refer to the ARM. Level control should be shifted to channel Y and the OWC notified. T.S. 3.3.10 should be entered.

12 Chg. Pp shaft breaks on start following 11X failure, however, the pump stops again when channel Y is selected. It is unlikely the crew will notice the failure here, but probably later in the scenario during the downpower or boration to meet reactivity control in EOP-0. When discovered the crew is expected to attempt to ensure boration via another means and to contact the OWC for assistance.

Next, 12 SG FRV Controller (1121) fails. The CRO should acknowledge the alarm and inform the CRS. The CRS should direct the CRO to maintain SG level and implement AOP-3G. The CRS should direct the CRO to place the controller switch in the Main Fail position. The CRO will control level via the PDI. The CRS should direct the OWC to contact the System Engineer for assistance.

The CRO acknowledges the SGFP Status Panel alarm and determines the alarm to be a SGFP Conditioner Level Low Alarm, informs the CRS and dispatches the TBO. Following the TBO report of a bad oil leak on 11 SGFP pump, a rapid downpower will be initiated to take 11 SGFP off. (The crew may notice the charging pump malfunction at this time.) The OWC should be contacted for assistance and notifications. As the power reduction to take 11 SGFP off is begun, 11 BA Pp trips off when started for the initial boration. The RO will either use 12 BA Pp or gravity feed from the BASTs to borate. At =50% power, 11 SGFP trips. The CRS should order the unit tripped due to loss of feed. EOP-0 is implemented, the RO notes 2 stuck CEAs and commences boration.

After the RO reports the status of RCS Pressure and Inventory, a loss of 11 4KV Bus occurs (may refer to AOP-7I).

The CRS should order a reassessment of safety functions. The RO should determine reactivity is no longer being met due to no charging flow and direct the TBO to align 13 Chg. Pp to 14 bus. The TBO's attempts to realign the 13 Charging Pump will initially be unsuccessful. The CRS will enter EOP-8 for failure to meet Reactivity Control.

EOP-8 is entered and the selected Success Paths begun. Boration is restored via HPSI injection. While working to establish boration, 11 AFW Pp trips the CRS or CRO should direct the TBO to investigate and align 12 AFW Pp.

After AFW has been restored and boration established, the scenario can be terminated.

SCENARIO #3 SETUP OVERVIEW/OBJECTIVES To evaluate the applicant's ability to conduct a unit power reduction, to implement the ARMs, OIs, AOPs, as appropriate, for malfunctioning systems and/or controls including a failure of PRZR level control channel (11 OX) which causes a broken shaft on 12 Charging Pp, a failed FRV Controller (1121) and a SGFP oil leak causing a rapid power reduction. A loss of 11 BA Pp occurs at the start of the downpower. The crew will be forced to trip the unit when the running SGFP trips. Two stuck CEAs require boration to meet reactivity but a loss of 11 4KV Bus will force the crew to EOP-8 for reactivity not being met.

In EOP-8, boration will be restored via BPSI injection and 11 AFW Pp will trip resulting in a loss of feed.

The crew can restore AFW by aligning 12 AFW Pp.

After the ADV controller fails the remaining seals fail on the affected RCP resulting in an RCS leak. After EOP-0 is entered, the RCS leak causes a SIAS actuation. SIAS 'A' fails to actuate requiring 11 or 12 HPSI Pump to be started manually to establish HPSI flow. As EOP-0 progresses, a steam leak begins in CNMNT from 12 SG requiring EOP-8 be implemented. The ADV Controller will not operate from the Control Room, the crew will have to operate the ADVs locally.

SCENARIO 1 OVERVIEW The candidates will take the shift at 100% power with instructions to maintain power.

After the crew has taken the shift, 11 CCW Pp trips. The CRO will acknowledge the alarms, inform the CRS and refer to the ARM. The crew will check for common mode failure and the CRS will direct the CRO to start 12 CCW Pp. The CRS should refer to AOP-7C and T.S. 3.7.5. The CRS contacts the OWC for assistance.

Several minutes later, PRZR Press Channel 10OX fails high. The RO should acknowledge the alarms, inform the CRS and refer to the ARM. The RO should note the lowering RCS pressure and the open spray valves. Pressure control should be shifted to channel Y and the spray valves verified shut. The RO should note the spray valves did not shut. The CRS should direct the spray controller be taken to manual and the spray valves closed. Once the spray valves are closed, the RO should stabilize RCS pressure. The CRS should contact the OWC for assistance.

About 3 minutes after the crew has regained RCS pressure control, the lower seal (first stage) fails on 1LA RCP.

The RO should note the alarm, inform the CRS and refer to the ARM. The crew should determine the lower seal on 1 A RCP has failed and monitor RCP parameters. The OWC and system engineer should be contacted.

Two minutes after the notifications have been made the ADV controller fails high causing the ADVs to open. The CRO diagnoses the open ADVs and inform the CRS. The CRS should direct the CRO to take manual control of the ADVs and shut them. The RO should maintain reactor power less than 100%. The CRS should refer to AOP-7K. The CRS contacts the OWC for assistance.

After the CRS has referenced AOP-7K, the 1LA RCP middle seal fails. The crew should implement ARM guidance and begin an expeditious shutdown in accordance with OP-3. The CRS should refer to OP-3 and direct the unit shutdown at a rate less than 30%/o/hour. The appropriate notifications should be made.

After power has been reduced at least 5%/o, the 1 A RCP upper seal begins to fail followed shortly thereafter by the failure of the vapor seal. With all the seals failed RCS leakage begins via the seals. The CRS will trip the unit based on high RCP Controlled Bleed Off temperature and EOP-0 implemented. When SIAS actuates, train 'A' fails to initiate automatically and manually. To establish HPSI flow 11 or 12 HPSI must be started manually.

After the first pass through the safety functions is complete, a steam break in CNNT begins. When the crew attempts to operate the ADVs, they will not operate from the Control Room. To establish heat removal via 11 SG, the ADV will have to be operated locally. The CRS should recognize two events are taking place and implement EOP-8. After the Success Paths have been selected and 12 SG isolated, the scenario can be terminated.
