Appendix D Scenario Outline Form ES-D-1 Events
- 1. BOP will perform Stroke Time Test on 3-FCV-43-13 and 3-FCV-43-.14.
- 2. ATC raises power to 100% with Recirc Flow.
- 3. The crew will respond to RWCU alarms indicating a leak and RWCU valve 3-FCV I will fail to automatically isolate. The ATC will isolate RWCU and take actions lAW 2-AOI-64-2A. The SRO will enter EOl-3 on High Secondary Containment Temperatures, evaluate Tech Spec 3.6.1.3, and determine Condition A must be entered. Also, TRM Technical Surveillance Requirement 3.4.1.1 to monitor Reactor Coolant Conductivity continuously cannot be met and samples must be drawn every 4 hours4.62963e-5 days <br />0.00111 hours <br />6.613757e-6 weeks <br />1.522e-6 months <br />.
- 4. BOP will respond to Bus Duct Cooling 3A Fan trip and take action lAW with ARPs, start standby Bus Duct Cooling Fan 3B.
- 5. Reactor Recirculation 3A Pump will trip, crew will respond lAW 3-AOl-68-1A. The ATC will close 3A RR Pump Discharge Valve. Small power oscillations will develop. The ATC will insert control rods to dampen oscillations and exit region 2. The SRO will evaluate Technical Specification 3.4.1; Condition A is required.
- 6. Level transmitter 58D will fail to less than -45 inches. This failure will result in a HPCI auto initiation. The crew will respond lAW ARPs. Crew will verify that level is in normal band and secure HPCI. The SRO will evaluate Technical Specification 3.3.4.2 Condition A and B, 3.3.5.1 Condition A, B and F, 3.3.5.2 Condition A and B, and 3.8.1 Condition D and J.
- 7. Shortly after the HPCI initiation a steam leak will develop in the HPCI Room, HPCI will fail to automatically and manually isolate. When attempting to manually isolate the HPCI steam valve, 3-FCV-73-2, the 3A 480V RMOV Board will be lost due to an electrical fault.
- 8. The crew will enter EOl-3 and scram the Reactor. A small ATWS will occur on the scram; power, level and pressure will be controlled lAW EOl-.1. When the second MAX safe temperature is reached the crew will Emergency Depressurize.
- 9. Turbine Bypass Valves will not be available on the scram with an ATWS of 20 rods.
Terminate the scenario when the following conditions are satisfied or upon request of Lead Examiner.
All but 6 Control Rods are inserted Emergency Depressurization complete Reactor Level is restored and maintained.

[3] WHILE OBSERVING the indications for the affected Relief valve on the Acoustic Monitor; BOP CYCLE the affected relief valve control switch several times as required:
- CLOSE to OPEN to CLOSE positions
[4] IF all SRVs are CLOSED, THEN CONTINUE at Step 4.2.4. (Otherwise N/A)
NOTES
- 1) Once initial transient of SRV opening has stabilized (pressure regulator compensation) the Heat Balance will indicate bad data.
- 2) The SRV TAILPIPE FLOW MONITOR may seal-in an OPEN position indication.
3-AOl-I-I 4.2 Subsequent Action NOTES
- 1) Once initial transient of SRV opening has stabilized (pressure regulator compensation) the Heat Balance will indicate bad data.
- 2) The SRV TAILPIPE FLOW MONITOR may seal-in an OPEN position indication.
4.2.1 Action if a fire exists with SRV stuck open
[1] IF an SRV is open and a fire exists in ANY Appendix R fire area, THEN (Otherwise N/A):
INITIATE a manual scram before the Suppression Pool temperature_exceeds 95°F.
3 Page 18 of 62 Simulator Event Guide:
Event 3 Component: ADS SRV 1-41 fails open, closes w/ inhibit switch.
4.2.2 Attempt to close valve from Panel 9-3:
[1] PLACE the SRV TAILPIPE FLOW MONITOR POWER SWITCH in the OFF position.
[2] PLACE the SRV TAILPIPE FLOW MONITOR POWER SWITCH in the ON position.
[3] IF all SRVs are CLOSED, THEN CONTINUE at Step 4.2.4.
(Otherwise N/A)
[4] PLACE MSRV AUTO ACTUATION LOGIC INHIBIT, 3-XS-1-202 in INHIBIT:
CT#1 Observe and report when 3-XS-1-202 is placed in Inhibit, ADS SRV 1-41 BOP closes.
[5] IF relief valve closes, THEN OPEN breakers (250V RMOV BD 3A BRKR 9B1, 250V RMOV BD 3C BRKR 8A, and BB2 BRKR 710)or PULL fuses (3-FU1-001-0041A, 3-FU1 -001-0041 B, 3-FUI-001-0041 C, and 3-FUI-001 -0041 D) as necessary usingAttachment I (Unit 3 SRV Solenoid Power Breaker/Fuse Table).
DRIVER Insert TRIGGER 12 to pull fuses 2 minutes after direction DRIVER Operator Does NOT perform step 6 until Breaker opened or fuses pulled.
[6] PLACE MSRV AUTO ACTUATION LOGIC INHIBIT 3-XS-1 -202, in BOP AUTO.
NOTES
- 1) Only the appropriate sections for the stuck open relief valve is required to be performed.
- 2) The ADS valves that have more than one power supply will AUTO TRANSFER on a loss of power, and are NORMAL SEEKING.
- 3) ADS Relief valves with hand-switches on Panel 25-32 are listed below and should be operated from that location first.
- 4) When opening breakers and pulling fuses, opening the breakers is the preferred method when time permits. However, the breakers with multiple locations will require opening each breaker to de-energize the control circuit. In this case, pulling the fuses from Panel 25-32 may be quicker than opening the breakers.

SRO May direct Suppression Pool Cooling placed in service lAW 3-01-74, Section 8.5 If Directed, places Suppression Pool Cooling in Service Loop I:
BOP 8.5 Initiation of Loop 1(11) Suppression Pool Cooling CAUTION PSA concerns with RHR in Suppression Pool Cooling Mode with a LOCA and a LOSP identify that severe water hammer may occur during the pump restart. Therefore, the following guidelines should be used to try and maintain the system below the PSA Risk Assessment goals:
RHR in suppression pool cooling should be minimized.
Two Loops of RHR in suppression pool cooling should be minimized Use two pumps per loop, if needed, to minimize total time spent in supp pool cooling.
Suppression pool cooling run times are tracked in 3-SR-2 to ensure Risk assessment goals are not exceeded.
NOTES
- 1) Suppression Pool Cooling is required to be initiated whenever necessary to maintain suppression pool temperature < 95°F, or when directed by other procedures.
- 2) All operations are performed at Panel 3-9-3 unless otherwise noted.
[1] VERIFY RHR Loop 1(11) in Standby Readiness. REFER TO Section 4.0.
[2] REVIEW the precautions and limitations in Section 3.0.
[3] NOTIFY the other units of placing Loop 1(11) of RHR in suppression pool cooling, the subsequent start of common equipment (i.e., RHRSW pumps) and associated alarms are to be expected.
[4] NOTIFY Radiation Protection for impending action to initiate Suppression Pool Cooling. RECORD name and time of Radiation Protection representative notified in the Narrative Log
[5] IF possible before placing RHRSW in service, THEN NOTIFY Chemistry that RHRSW sampling is to be initiated (RI-IRSW sampHng requirements).

Event 3 Component: ADS SRV 1-41 fails open, closes wI inhibit switch.
[6] VERIFY at least one RHRSW Pump is operating on each EECW Header NOTES
- 1) Step 8.5[7] initiates Suppression Pool Cooling for RHR Loop I.
- 2) Step 8.5[8] initiates Suppression Pool Cooling for RHR Loop II.
- 3) RHR Pump(s) may be operated with no RHRSW flow through the associated RHR Heat Exchanger(s), in support of maintenance or testing, provided the RHRSW side of the heat exchanger is pressurized and is approved by the Unit Supervisor.
[7] PLACE RHR Pump and Heat Exchanger A(C) in service as follows:
[7.1] START an RHRSW Pump to supply RHR Heat Exchanger A(C).
CAUTIONS
- 2) When operating RHRSW through the heat exchangers, damage can occur to the RHRSW discharge valves for the RHR Heat Exchanger if operating at low flows and high differential pressures for long periods. In order to lower the differential pressure the valves experience, flow through the in service heat exchanger(s) should be established such that the total header flow is 4000 gpm. When operating RHRSW in split mode with other units, this is calculated by adding the individual flows from each of the in service RHR heat exchangers.
[7.2] ESTABLISH RHRSW flow by performing one the following:
[7.2.2] THROTTLE OPEN RHR HX 3A(3C) RHRSW OUTLET VLV, 3-FCV-23-34(40), as required for cooling (if another is maintaining minimum flow) and/or to maintain between 4000 and 4500 gpm RHRSW flow as indicated on 3-Fl-23-36(42),

Event 3 Component: ADS SRV 1-41 fails open, closes wI inhibit switch.
[7.8] VERIFY OPEN RHR SYS I SUPPR CHBRIPOOL ISOL VLV, 3-FCV-74-57.
CAUTIONS
- 1) To prevent excessive vibration, RHR pumps should not be allowed to operate for more than 3 minutes at minimum flow.
- 2) Capacitor bank fuses are subject to clearing when the unit boards are being supplied from the 161kV source and large pumps are started. Unit Supervisors should evaluate placing the Capacitor Banks in Manual prior to starting RHR pumps per 0-Ol-57A.
- 3) When throttling RHR SYS I SUPPR POOL CLG/TEST VLV, 3-FCV-74 59, maintain Blue light illuminated in order to maintain LPCI operability.
NOTE RHR flow should be monitored while in operation on 3-Fl-74-50, RHR SYS I FLOW.
RHR flow should remain 10,000 gpm for 1-pump operation and is limited to <
1 3000 gpm, for two pump operation, due to the flow restricting orifice in the test return line.

Event 1 Normal: RFPT 2B Overspeed Trip Exerciser Test SRO Directs BOP to perform RFPT 2B Overspeed Trip Exerciser, 2-01-3 section 8.10 8.10 Overspeed Trip Exerciser Test NOTES
- 1) The following steps will test the circuitry associated with the overspeed trip test and mechanical overspeed trip lockout. The test may be performed at speed or stopped; it should be performed prior to rolling the turbine off the turning gear and periodically with the applicable REP in operation. This test will normally be performed during scheduled reductions in power with reactor power less than 90%.
- 2) The success of this test depends on the mechanical overspeed trip bolt actuating as a result of oil pressure. The system was designed for this test to be performed with the RFPT at normal operating speed. The test may not function properly at less than 75% speed (4125 rpm) due to the trip mechanism being sluggish at speeds well below rated. If this is the case, no action is required except to reperform the test at a higher speed.
- 3) The following steps are performed at Panel 2-9-6.
BOP Performs RFPT 2B Overspeed Trip Exerciser Test, 2-01-3 section 8.10
[1] OBTAIN Unit Supervisor approval to perform this test.
