Appendix D Scenario Outline Form ES-D-1 Scenario No.: One Operating Test No.: 2011-301 Narrative Summary Event # Description
- 1. The BOP Operator will coordinate with the field operator to test the Generator Emergency Seal Oil Pump per CPS 3109.01 Section 8.1.2.3.
- 2. The ATC Operator will continue the Hot Restart. First milestone this shift will be withdrawing control rods to criticality.
- 3. Rod 28-41 will indicate a failure to move upon the ATC Operators initial attempt to withdraw it. The ATC Operator must increase drive water pressure (one increment of
~ 50 psig) to withdraw the rod per CPS 3304.01 Section 8.3.3.
- 4. Annunciator ROD OUT BLOCK (5006-2H), SRM UPSC ALARM OR INOP (5005-1K), SRM PERIOD (5005-2K) and SRM DNSC (5005-3K) come in due to SRM B failing erratic. The B SRM channel must be bypassed per CPS 3306.01 Section 8.2.2 to clear the rod block and proceed with the startup. Technical Specification 3.3.1.4 action A.1 and ORM 2.2.2 Action 3.2.2.a will be evaluated and found to be satisfied.
- 5. Annunciator HPCS WATER LEG PUMP DISCHARGE PRESSURE LOW (5062-7D) comes in due to the HPCS Water Leg Pump shaft shear. The BOP Operator will dispatch a field operator to investigate. Upon the report of a shaft shear, the BOP operator will stop the HPCS Water Leg Pump and direct the field operator to pull the HPCS Pump Breaker control power fuses per CPS 3309.01 Section 4.3. Technical Specification LCO 3.5.1 Actions B.1 and B.2 will be evaluated requiring verification by administrative means that the RCIC system is operable when required AND the HPCS system is restored to operable status within 14 days.
- 6. Annunciator STANDBY LIQUID CONTROL OUT OF SERVICE (50677-8F) comes in along with postage stamp C001A or F001A PWR LOSS or OVLD due to a loss of power to SLC Suction Valve A From SLC Storage Tank - 1C41-F001A. The valves green indicating light is dark. The BOP Operator will dispatch a field operator to investigate. Technical Specifications LCO 3.1.7, Action A. will be evaluated which will require that the SLC subsystem be restored to operable within 7 days.
- 7. Annunciator AUTO TRIP PUMP/MOTOR (5019-1A) comes in due to a trip of the Condenser Vacuum Pump 1A (0CA01PA). The BOP Operator notes that the trip is NOT due to Hi MSL Rad and starts the standby Condenser Vacuum Pump per CPS 3112.01 Section 8.1.1.
- 8. Multiple annunciators are received due to The RCIC steam supply line develops a leak causing the RCIC room temperature to rise resulting in an EOP-8 entry. RCIC cannot be isolated from the MCR. A scram is required prior to exceeding the Maximum safe temperature.
- 9. When a Reactor Scram is attempted, an Auto Scram failure occurs due to a fault in the Reactor Protection system. The ATC Operator must perform a manual initiation of the SCRAM OR ARI to insert the control rods.

- 2. The ATC Operator will raise reactor power to 96% using a combination of control rods and reactor coolant flow.
- 3. Annunciator ROD DRIFT (5006-4G) come in due to rod 20-45 drifting outward.
The ATC Operator will take the Immediate Actions and applicable Subsequent Actions as directed by the CRS for an Inadvertent Rod Movement per CPS 4007.01. Rod 20-45 will drift outward until individually scrammed at the Hydraulic Control Unit (HCU). Technical Specification LCO 3.1.6 Actions C.1 and C.2 will be evaluated requiring full insertion of the inoperable control rod in 3 hours3.472222e-5 days <br />8.333333e-4 hours <br />4.960317e-6 weeks <br />1.1415e-6 months <br /> and disarming the associated CRD in 4 hours4.62963e-5 days <br />0.00111 hours <br />6.613757e-6 weeks <br />1.522e-6 months <br />. Technical Specification LCO 3.1.6 Actions A.1 will also be evaluated will be evaluated and found not to apply.
- 4. Annunciator LOW PRESS MAKE-UP COND XFER PUMPS DISCH HDR (5014-2C) comes in due to the Make-Up Condensate Transfer Pump 1B (0MC01PB) shaft shear. The BOP Operator will dispatch a field operator to investigate. Upon the report of a shaft shear, the BOP operator will stop the failed pump and start the standby pump per CPS 3208.01 Section 8.1.1 (or 8.2.2).
- 5. Annunciator NOT FULLY CLOSED CDSR EMERG O/FLOW VLV 1CD020 (5014-4B) is received or an Operator notes Hot well Level is lowering. Upon discovery, the ATC Operator recognizes the failure of the Hot well Level Control Valve controller to control in automatic and takes manual control per CPS 3104.01 Section 8.6.1.
- 6. Annunciator AUTO TRIP PUMP/FAN DIVISION 1 (5050-1A) comes in due to the Train A Control Room Supply Fan (0VC03CA) tripping. The BOP Operator will coordinate with the field operator to shift Control Room HVAC (VC) to Train B per CPS 3402.01 Section 8.1.7. Technical Specification LCO 3.7.3 Actions A.1 will be evaluated requiring restoration of control room ventilation subsystem to an operable status within 7 days. Technical Specification LCO 3.7.4 Actions A.1 will also be evaluated requiring restoration of control room AC subsystem to an operable status within 30 days.
- 7. Multiple annunciators are received due to the A Reserve Auxiliary Transformer (RAT A) tripping on Differential Overcurrent. IA containment & drywell isolation valves (1IA005/006 and 1IA007/008) go shut. Failure of the shift to recognize and reopen these valves will lead to a SCRAM. Concurrent with this event, the circuit breaker supplying the HPCS injection valve (1E22F004) trips open on overcurrent.
- 8. An unisolable RR loop leak develops. The RCIC turbine will trip when started and cannot be reset. This failure completes a loss of all major high pressure feed sources.

- 9. Reactor Pressure Vessel (RPV) water level will lower until it reaches Top of Active Fuel (TAF). At that time the CRS will enter EOP-3, blowdown, recover and restore RPV level per EOP-3.
- 10. The B RHR Pump (1E12AC002B) fails to automatically start. The BOP Operator must manually start the B RHR Pump to maximize injection of available sources per EOP-1.
EOP 1, 3, 6 Critical tasks:
- Enter EOP-3, Blowdown.
- Maximizes injection to recover level above TAF. Restore and control RPV water level to a band of Level 3 to Level 8.

- 1. CPS 9080.02, DG 1B Operability - Manual and Quick Start Operability, has been completed. The BOP operator will secure DG 1B and place it back in standby.
- 2. The Load Dispatcher will call the MCR, declare a grid emergency and request that CPS lower generator output 100MWe within the next thirty (30) minutes. The ATC Operator will lower reactor power/generator output using reactor coolant flow.
- 3. Annunciator OUT OF SERVICE DIESEL GEN 1B (5061-7F) comes in due to low Starting Air Pressure (190 psig). The BOP operator will dispatch a field operator to investigate. No cause will be evident.

- 4. Annunciator CLOGGED OIL FILTER CONDENSATE BOOSTER PUMP 1A (5001-1H) comes in due to a clogged CUNO filter. The ATC Operator will dispatch a field operator to clear the alarm. Attempts are unsuccessful and the ATC Operator will startup the standby condensate booster pump and shutdown the affected pump per the Annunciator Response Procedure (ARP).
- 5. Annunciator AUTO TRIP PUMP/MOTOR (5040-1B) and RECIRC MTR A/B WDG CLG WTR FLOW LO (5003-3D/3K) come in due to a trip of the B Component Cooling Water (CCW) Pump. The BOP Operator will start the standby pump per the Annunciator Response Procedure (ARP).

Technical Specification LCO 3.3.1.1 Actions A.1 will be evaluated requiring the channels affected function in trip within 48 hours5.555556e-4 days <br />0.0133 hours <br />7.936508e-5 weeks <br />1.8264e-5 months <br />. Technical Specification LCO 3.3.1.3 Actions A.1 or A.2 or A.3 will be evaluated requiring the channel in TRIP or the associated RPS trip system in TRIP or initiate an alternate method to detect and suppress thermal hydraulic instability oscillations all within 30 days.
- 7. Annunciator HIGH TEMP TURB GEN LUBE OIL (5018-3A) comes in due to a failure in the auto portion of the TURB OIL CLG WTR Controller. The BOP operator will diagnose the problem with the controller, place the controller in MANUAL and coordinate with the ATC Operator to stabilize turbine oil outlet temperature.
- 8. Annunciator CLEANUP PUMP SEAL GLAND PLATE TEMP HI (5000-2E) comes in due to RWCU Recirc Pump B (1G33-C001B) developing excessive seal leak requiring its removal from service. The ATC Operator will dispatch a field operator and coordinate/perform operations per CPS 3303.01 Sections 8.1.3 and 8.1.4.
- 9. The A Inboard MSIV drifts shut, resulting in a transient that causes a Group 1 isolation due to the increased steam flow in the remaining three Main Steam Lines which in turn causes a Reactor Scram.
- 10. A Reactor Coolant Leak develops followed shortly by a Drywell to Containment leak.
When Containment Pressure exceeds Figure N, EOP-3 is entered and a blowdown is performed.
- 11. Upon the initiation of ADS 2 SRVs 41B and 41D fail to open which requires manual operation to open two more relief valves to complete the blow down.
