Scenario #1 Overview RO

initial Conditions: Unit 1 : 45% power - EOL, Unit 2: 1Q0%, Unit 3: 100%

Turnover:

e Startup in progress after adding oil to 181 RCP

e SASS in MANUAL for !&Etroubleshooting

e 1B MDEFDW Pump 00s

After turnover, the crew should stad 1B I RCP

2 1 Start 4 B1 RCP: (N, OATC)

a9 Reactor power was reduced so oil could be added to the 184 RCP. The oil

addition has been completed and the crew is directed to start the 1E31 RCP per

OPII/AI1103/006.

TIME = 5 minutes

4) 1B1 RCP AC Oil Lift pump wili not develop adequate discharge pressure: (6,

OAK)

a) Prior to stading the I Bf RCP, the RCP AC Oil Lift pump will be started. The

OAC should be monitored and the RCP started after the low oil pressure a8am

clears. The low pressure condition will not clear and the AC Oil Lift pump wilt stop

after three minutes. The operator should follow procedural guidance and use the

DC Oil Lift pump and complete starting the 181 RCP.

a) The crew should utilize Plant Transient Response to stabilize the plant. The

Turbine master will transfer to manual. The O A K should take the Diamond

Panel and the FDW Masters bo manual. FDW, Control Rods, and Turbine Header

pressure should be adjusted to stabilize the plant.

b) The SRO should refer to AP128 (BCS Instrument Failures).

TIME = 10 minutes. TOTAL 20 min.

4) BWST rupture: (C,ALL) (TS)

a) A crane will damage the BWST resulting in level rapidly decreasing to a24 feet.

b) The SRO should refer to TS 3.5.4and determine that a unit shutdown is

required.

TIME = 10 minutes, TOTAL 30 rnin.

Page 1 of 3

Scenario #I Overview RO

5) Manual unit shutdown: (R, BATC)

a9 FDW, Control Rods, and Turbine Header pressure will be controlled to manually

shutdown the unit.

TIME = 28 minutes, TOTAL 40 min.

$1 RCS NR Pressure fails HIGH: (I, O A K )

a) After the manual unit shutdown, RCS NR Pressure will fail high and the crew

should utilize Plant Transient Response to stabilize the plant.

b) The PPK heaters will de-energize and PZR spray (1RC-2 ) will open. The PORV

(1RC-66) will also open. Actual RCS pressure will decrease and the reactor wilt trip

on low pressure in about one minute without operator action.

c) The crew should refer to the ARGs and the SRO should direct the crew to close the

PORV or 1 RC-4 (Spray Block) and 1RC-1 (PZR Spray). The PZR heaters should

be cycled as required to control RCS pressure.

d) The SRO should refer to AP/28 (ICs instrument Failures).

TIME = 5 minutes. TOTAL 45 min.

7) Main FDW pumps trip and Main Turbine Fails to trip (Lockout EHC Pumps): (C,

OAK)

a> Both Main FDW pumps will trip resulting in a reactor trip. The Main Turbine

should trip but does not. This will result in a reduction in steam pressure in both

SGs until actions are taken to trip the turbine. The will result in RCS overcooling

until the Main Turbine is tripped.

b) While performing IMAs, the O A K should diagnose that the turbine did not trip

and then perform the WNO step which will stop both EHC pumps. This wilt cause

the turbine to trip.

TIME = Iminutes, TOTAL 46 min.

8 ) R 6 S leak to SBLQCA (ramp over 10 minutes): (M, ALL)

a ) The RCS leak will require entry into AP/2 (Excessive RCS Leakage). The leak

will increase causing a loss of SCM.

$1 RULE 2 (Loss OB SCM) wiill be implemented and the SRO will transfer to the Loss

of Subcooling Margin (LOSCM) tab of the EO$. The SRO will then transfer to

the LOCA Cosldown (LOCA CD)tab of the EO$.

c> EOP Enclosure 5.1 (ES Actuation) will be implemented. The A RBCU will not

receive an ES signal and will not go to LOW speed. The RO should diagnose this

and place the A RBCU in LOW speed.

TIME = 20 minutes. TOTAL 66 min.

Scenario #I Overview RO

9) RCS leak isolated, SCM increases > 0°F: (U, ALL)

a) After transfer is made to the LBCA CD tab ~f the EO$ the leak will be isolated.

Phis will cause SCM to increase > 0°F and a transfer should then be made to

Subsequent Actions. After the transfer to Subsequent Actions is made the

scenario may be stopped.

TIME = 10 minutes, TOTAL 76 min.

1) Pressurize the LDST with H2: (N,OATC)

Statalarm will actuate indicating that the LDST H2 pressure is low. Crew should repr

to the A 8 6 and the LDST Pressure vs bevel curve. The crew should then add H

to the LDST.

TIME = 10 minutes

2) 1H-1 fails OPEN: (C, OATC) (TS)

During the H*addition to the LDST, 1H-1 (LDST Supply) will fail OPEN repiring the

OATC to direct the primary NEO to close the isolation valve to stop the H addition.

Isolation by the NE0 will be delayed and BOTH trains of HPI must be declared

inoperable due to operation outside of permissible Operating Region on the LDST

Pressure vs bevel curve.

TIME = 5 minutes, TOTAL 15 min

3) Phdfails HIGH: (I, QATCJ

a) The crew should diagnose the failure and stabilize the plant by using the Plant

Transient Response process.

b) The BAPC should place both FDW Masters and the Diamond Panel to manual to

mitigate the transient and stabilize the plant.

e) This failure will not be repaired and the ICS will remain in manual.

d) The SWO should refer to AW28 (ICs Instrument Failures).

TIME = 5 minutes, TOTAL 20 min

4) I A CC Pump trips: (C, O A K )

a) The crew should refer to ARG and to AP/(32Q(Loss of Component Cooling). The

O A K should manually start the standby CC pump.

b) The crew should initiate investigation and repair of l A CC pump and 1B CC auto

stakt failure.

TIME = 5 minutes, TOTAL 25 min.

5) iHP-5 Fails closed: (c,ONC) ~ , b R O A-

a) Kecognize that 1HP-5 closed due to high letdown temperature, and refer to the

ARG for stat alarm 1SA-2/C-1, Letdown Temperature High.

b) When the crew recognizes that 1HP-5 has failed closed, the SRO should refer to

AW032, Loss of Letdown.

c) An operator should be dispatched to manually open 1HP-5.

TIME = 10 minutes, TOTAL 35 mln.

6) ID1 Heater Drain Pump oil leak: (C, All)

a9 The basement NE0 will notify the control room that the 1D1 HDP has a severe

oil leak. Crew should refer tcr 8P/1//1106/0028 (Shutdown of the 1D l HDP).

The SWO should direct the crew to reduce CTP to .e 87% and secure the 1D1

HDP.

TIME = I O minutes, TOTAL 45 min.

5 ) Manual reactor power decrease: (R, O A K )

a) The OATC should reduce power with the control rods and the FDW Masters in

manual.

TIME = 15 minutes, TOTAL 60 min.

8 ) Loss of Main Feedwater with 1FDW-316 Failed CLOSED: (M, ALL)

a) After reactor power has been reduced both main FDW pumps will trip and

4 FBW-346 will fail closed. The SRO will refer to the EOP. Rule 3 (boss of Main

or Emergency Feedwater) should be implemented after the completion of lMAs

and symptoms check because of the loss of Main FBW. The failure of IFDW-316

should be diagnosed and ENV aligned through the startup header. Until flow is

aligned through the B startup header no Main OF ENV flow will reach the SGs

due to the 1A MDEFDWP not operating and 1FDW-316 failed closed. If the

alignment through the startup header is delayed HPI Forced cooling must be

initiated.

TIME = 10 minutes, TOTAL 90 min.

9) Loss of Main and Emergency Feedwater, IB MBEFDWP trips (CBP Feed): (M,

ALL)

a) After flaw has been established through the startup header the 1B MDEFBWP

will trip. This results in a total loss of Main and Emergency Feedwater. The SRO

should transfer to the Loss of Heat Transfer (LOHTJtab of the EOP. The OAT@

should feed the OTSGs using the CBPs per the guidance in Rule 3 (Loss of Main

or Emergency Feedwater).

TIME = 10 minutes, TOTAL 80 min. 7

1O)TDEFDWP returned (CBPfeed recovery)

a) After the plant is stable, the crew will be notified that the TDEFDWP has repaired

and is now available. The SRO will direct the crew to recover from CBP feed by

using the TDEFDWP to feed the SGs per EOP guidance. When the TDEFDWP

is feeding the SGs and the unit is stable the scenario may be stopped.

TIME = 10 minutes, TOTAL 90 min.
