Appendix D Scenario Outline Form ES-D-1 Event 1:

Power is at 2 X 10-3% power and critical data has been taken. The crew will raise reactor power from the present level to beyond the POAH and continue power ascension.

Verifiable Actions:

OATC Withdraw control rods to establish a positive SUR and raise power to between 1 to 3% as read on the Power Range Nuclear Instrumentation, then stabilize reactor power using control rods.

uO Unblocks SR NIS Hi Flux at Shutdown.

uO Controls AFW flow as the POAH is reached to control SG levels.

Event 2:

Loop # 3 NA Tcold fails high resulting in PRZR program level failing high. This will result in charging flow controller FV-0121 throttling open to raise PRZR level. There will be a PRZR LO LEVEL DEVIATION (ALB1 1 DOl ) annunciator to warn the crew that PRZR program level is failed high. If the crew does not have FIC-0121 in manual, when they defeat loop # 3 NR Tcold PRZR level will be high relative to program level, FIC-0121 will reduce to minimum causing a possible flashing of letdown.

Verifiable Actions:

OATC Performs lOA of 1 8001 -C section B and verifies rods are in manual.

OATC Takes manual control of FV-1 21 and reduces demand to control charging flow.

OATC Selects affected loop # 3 on both the Tavg and Delta T defeat switches.

OATC Controls charging flow to restore program PRZR level and returns FV-121 to automatic if desired.

LCO 333 Post Accident Monitoring (PAM) Instrumentation, Condition A LCO 333 Post Accident Monitoring (PAM) Instrumentation, FU 1 5 Condition F Event 4:

Steam Generator # 2 ARV PV-3010 pressure transmitter fails high resulting in PV-3010 opening causing a reactor power excursion and entry in AOP-1 8008-C, Secondary Steam Leak.

RCP # 1 rising vibration with vibration alert alarm and high vibration alarms (Immediate Trip Criteria exceeded)

Verifiable Actions:

OATC Starts RCP # 1 oil lift pump.

OATC Trips RCP # 1 by opening the non-i E breaker first.

OATC Places RCP # 1 spray valve in manual and closes RCP # 1 spray valve to prevent short cycling of the spray lines causing PRZR spray to be ineffective at PRZR control.

Technical Specifications:

LCQ 3.4.4 RCS Loops Modes i and 2, Condition A Event 7, 9 1O 11:

RCS Small Break LOCA of 75 gpm, LOCA will increase to 300 gpm requiring a Reactor trip and manual Safety Injection. At 300 gpm RCS pressure will slowly lower to i800 psig with SI injection flow present and PRZR level will be off scale low.

LCO 3.4.i3 RCS Operational Leakage, Condition A.

5

Appendix D Scenario Outline Form ES-D-1 Event 8:

Break turns into large break LOCA after entry into 1 901 0-C and prior to step # 4 for RCP Trip Criteria.

Verifiable Actions:

OATC Manually trips the RCPs after DBA LOCA in first steps of 1 901 0-C.

NOTE to Examiners:

The natural procedure flow path at this point will progress until step 23 of E-1 to check for transition to 1 901 2-C, ES-i 2 Post LOCA Cooldown and Depressurization which will NOT be met.

The procedure will transition you back to step 1 7 of 1 901 0-C to wait for Cold Leg Recirculation criteria on RWST Lo-Lo Level to be met.

The scenario may be stopped after this point with chief examiner approval or sooner than the crew returning from step 23 to 1 7 if desired for time considerations.

CRITICAL TASKS:

1 ) Manually actuates Safety Injection from QMCB panel A2 hand switch (the other switch will not function) by no later than step # 4 of 1 9000-C Immediate Operator Actions to ensure adequate core cooling during LOCk

2) Manually starts RHR pump A no later than RCS pressure dropping to lower than the RHR pumps discharge pressure to ensure adequate ECCS injection flow for core cooling and recirculation capability during an ensuing DBA LOCk

3) Manually close at least one CVI damper for Containment Mini-Purge which fail to automatically close ensuring termination of release flow path to the environment from Containment during a LOCA Action must be performed by completion of Initial Operator Actions of 1 9000-C.

The scenario may be stopped after the Reactor Coolant Pumps are tripped per the RCP Trip Criteria of 19OOOC or 19010-C at Chief NRC Examiner discretion.

CRITICAL TASKS:

I ) Manually starts SIP B to ensure adequate ECCS injection flow for core heat removal during small break LOCk This will be performed prior to receipt of a valid Core Cooling Orange Path due to CETs temperatures > 71 1 °F with RVLIS Full Range > 41 % OR CETs temperature < 711°F with RVLIS Full Range < 41%.

2) Manually trip the Reactor Coolant Pumps per the RCP Trip Criteria on the Foldout Page of 1 9000-C. This will be performed no later than step # 1 1 of 1 9000-C, if RCP trip criteria are met prior to reaching this step. If trip criteria are reached after this step, this will be performed per Foldout Page of 19000-C or step #4 of 19010-C, whichever comes first.

This will reduce inventory loss out the break during a classic small break LOCA event and will reduce peak clad temperatures than if the pumps were to trip later during the accident.

13006-1, CVCS Section 4.4.13, Restart of CCP or NCP following Loss of a Charging Pump.

CAUTIONS At BOL, while borating to maintain Tavg, the calculated delta boron concentration between the RCS and the last time the CCP/NCP was placed in service may be incorrect. Experience has shown that high concentrations of borated water tend to collect in the suction piping of the idle pumps, resulting in a higher boron concentration in the CCP/NCP than the RCS. This may cause and unexpected boration and temperature reduction, when the pump is placed in service or tested.

Restart of a charging pump should not be delayed in order to flush the pump prior to start.

OATC 4.4W 1 3. 1 PRIOR to starting the pump and based on the conditions described in the first caution above, a slight boration should be anticipated and a briefing on compensatory actions to offset the boration should be conducted.

CREW CAUTION: A determination should be made that loss of the Charging Pump was not due to air/gas binding before starting the same or another pump.

Appendix D Scenario Outline Form ES-D-1 Event 9:

OATC Trips RCP # 4 when a PRZR spray valve will not shut, trips RCP # 1 if necessary.

The scenario may be stopped after this point with chief examiner approval.

CRITICAL TASKS:

1 ) Isolates SG # 1 to limit secondary contamination and potential release environment by performing the following actions no later than the 1 9030-C procedure steps These are steps 6 through 1 1 of I 9030-C.

. Adjusts SG # 1 ARV potentiometer set point to 7.73 (to control at 1 1 60 psig).

. Trips the TDAFW pump by closing PV-1 51 29 (Trip and Throttle Valve)

. Closes SG # 1 MSIV and Bypass valves

. Isolates FW flow to SG # 1 (MFIV, MFRV, BFIV, BFRV, TDAFW, MDAFW, and SGBD and Sample valves all shut)

2) Depressurizes PRZR to refill the PRZR with ECCS injection and to limit break flow using normal PRZR spray to meet conditions of step 37 of 1 9030-C.

3) Stops RCP # 4 when PRZR spray valve will not fully close. (Stops RCP # 1 if necessary)

This prevents a loss of RCS pressure control requiring a transition to the SGTR ECA series of EOPs. Also, an uncontrolled backfill of the SG from the secondary side may occur resulting in possible loss of shutdown margin and contaminants being introduced into the primary side. This action is performed per step 38a RNO of 19030-C.

Main Feed regulating valve to SG # 3 will fail shut requiring a manual reactor trip by the crew.

Following the trip, 3 control rods will be stuck partially out requiring an emergency boration.

HV-8104 Emergency Boration valve will not open from the QMCB.

Verifiable Actions:

OATC Initiates an emergency boration of the RCS from the RWST through the Normal Charging flow path by opening 1 FV-1 1 OA and 1 FV-1 1 OB and adjusting charging flow to obtain the required boration flow rate of 30 gpm and required charging flow rate of 42 gpm.

2) Manually closes at least one CVI damper in each flow path to prevent a radiation release flow path from the RCS via SG # 3 to the environment. CVI isolation must be performed no later than the Initial Operator Actions of 1 9000-C.

3) Manually isolate SG # 3 to limit blow down to one SG limiting CNMT pressure rise and Challenge to the Containment. This also limits RCS cool down and possible PTS condition by closing the following valves. These will be done no later than the procedurally directed steps of 1 9020-C.
