QF-1030-19 Rev. 5 (05/12/05) 2007 ILT NRC 1,LOCA/ Blowdown, Rev. 0 SCENARIO OVERVIEW:

INITIAL CONDITIONS:

1. This Evaluation can be run from the following Requalification Exam Scenario Standard (Specific) IC sets:

IC-231

3. The following equipment is OOS:

RCIC SEQUENCE OF EVENTS:

Event 1: MSIV Closure Test 0008

Reactor power is 100%. RCIC is inoperable due to planned maintenance on the trip/throttle valve. The schedule requires test 0008, MAIN STEAM LINE ISOLATION VALVE CLOSURE SCRAM TEST be performed.

The test will progress normally for the 4 Inboard MSIVs.

When step 3A for the A Outboard MSIV (Depress and hold MSIV test pushbutton until protective relays energize) the MSIV will not move from its fully open position.

ITS will be reviewed and be determined that LCO 3.6.1.3 is applicable, Condition A, Required Action A.1 requiring the steam line be isolated within 8 hours9.259259e-5 days 0.00222 hours 1.322751e-5 weeks 3.044e-6 months .

Event 2: CRD Flow Control Valve Failure

In-service CRD Flow Control Valve fails and approximately 3 minutes later annunciator 5-B-41 (CRD HI TEMPERATURE) alarms.

The OATC recognizes that the CRD Flow Control Valve failed closed requiring a shift to the standby FCV.

Event 3: ADS Inadvertent Initiation

Annunciators 3-A-25, (AUTO BLOWDOWN TIMER ACTIVATED), prompt the crew to determine an ADS timer initiation.

The BOP operator takes action to verify timer actuation and carries out the actions of C.4-G to place the ADS AUTO/INHIBIT switch to INHIBIT.

ITS will be reviewed and be determined that LCO 3.5.1 is applicable, Condition L. The CRS should prepare to be in MODE 3 within 12 hours1.388889e-4 days 0.00333 hours 1.984127e-5 weeks 4.566e-6 months .

Page 5 of 27

QF-1030-19 Rev. 5 (05/12/05) 2007 ILT NRC 1,LOCA/ Blowdown, Rev. 0 Event 4: Main Turbine Vibration

Vibration on bearings 7 and 8 are noted by the crew to be rising or acknowledged when Page 6 of 27

QF-1030-19 Rev. 5 (05/12/05) 2007 ILT NRC 1,LOCA/ Blowdown, Rev. 0 annunciator 7-B-33, TURB VIBRATION HIGH alarms at 10 mils. The computer alarm actuates at 7 mils.

The CRS will direct a power reduction to mitigate the condition.

When the reactor power is lowered, turbine vibrations will lower and stabilize.

Event 5: RBCCW Pump Trip

The running RBCCW pump trips and the standby pump fails to auto start.

The BOP responds to annunciator 6-B-32 (RBCCW LOW DISCH PRESS)

BOP starts the standby pump per C.4-B.02.05.A, Loss of RBCCW, and reports system pressure returns to normal.

Annunciators 4-B-21 (CLEAN UP FILTER DEMIN FAILURE) 4-B-26 (CLEAN UP DEMIN TEMP HI) and 4-B-31 (CLEAN UP DEMIN TEMP HI HI) will cue the crew that the RWCU system has tripped.

Event 6: Loss of Air to A FRV, FRV Lockup

The A FRV experiences a loss of air due to a localized air line fitting leak and the FRV locks up as expected.

The OATC responds to annunciator 5-B-40 (FW CONTROL VALVE LOCKED) and places the un-locked FRV in manual control.

The out plant operator will be dispatched and report that the leak has been repaired allowing the FRV lockup to be reset and restore FWLC to automatic control.

Event 7: Recirc Leak Inside Primary Containment

A small Recirc line break inside the primary containment will occur which will result in rising drywell pressure.

The CRS will direct a reactor scram and EOPs-1100 (RPV CONTROL) and 1200 (PRIMARY CONTAINMENT CONTROL) will be entered.

Torus cooling, sprays and drywell sprays will be directed to mitigate conditions in the primary containment. Drywell sprays will not be able to be initiated on either RHR loop.

The CRS will direct a blowdown (or Anticipate Emergency Depressurization) due to no being able to maintain drywell temperature below 281°F.

3 ADS valves will be directed to be opened to depressurize the RPV. One of the ADS valves will not open and a non-ADS SRV must be manually opened.

The scenario will be terminated when the RPV has been depressurized, RPV water level is being maintained above 9 inches, and with concurrence of the lead evaluator.

QF-1030-19 Rev. 5 (05/12/05) 2007 ILT NRC 2, ATW S, Rev. 0 SCENARIO OVERVIEW:

INITIAL CONDITIONS:

1. This Evaluation can be run from the following Requalification Exam Scenario Standard (Specific) IC sets:

IC-232

3. The following equipment is OOS:

None SEQUENCE OF EVENTS:

Event 1: OSP-TRB-0570, EXERCISE MAIN TURBINE BYPASS VALVES

Reactor power is ~89%. The schedule requires test OSP-TRB-0570, EXERCISE MAIN TURBINE BYPASS VALVES be performed.

When step 2 is performed for the #2 turbine bypass valve, it will fail to open due to an instrument malfunction.

ITS will be reviewed and be determined that LCO 3.7.7 is applicable, action A.1. The CRS should direct that repairs be initiated to be completed within 2 hours2.314815e-5 days 5.555556e-4 hours 3.306878e-6 weeks 7.61e-7 months .

A report from the I&C shop will be made to inform the CRS that the repairs can be completed within 1 hour1.157407e-5 days 2.777778e-4 hours 1.653439e-6 weeks 3.805e-7 months .

Event 2: 11 CRD Pump Trip

The running CRD pump trips.

Annunciators 5-B-17 (CHARGING WATER LO PRESS), 5-B-25 (CRD PUMP 3-16A BREAKER TRIPPED), and 5-B-26 (CRD PUMP 3-16A OL) alarm.

The non-running pump is required to be manually started.

Page 5 of 23

QF-1030-19 Rev. 5 (05/12/05) 2007 ILT NRC 2, ATW S, Rev. 0 Event 3: Pressure Regulator Oscillation, EPR

The OATC / BOP operator reports oscillations of reactor power, level, and/or pressure, and MWe output.

The BOP operator will initiate action to stabilize pressure control by lowering the MPR set point so it will take control and running down the EPR setpoint to clear the oscillations per B.05.09-05.H.1 and B.05.09-05.H.3.

Page 6 of 23

QF-1030-19 Rev. 5 (05/12/05) 2007 ILT NRC 2, ATW S, Rev. 0 ITS will be reviewed and be determined that LCO Condition 3.11.A (B), (C) are not applicable, at this time, but would need to be reviewed again if power is <90%.

Event 4:

RPS RPV high pressure relay 5A-K5C fails initiating annunciators 5-B-11 (REACTOR VESSEL HI PRESS SCRAM TRIP) and 5-B-4 (REACTOR AUTO SCRAM CHANNEL A).

The crew determines that a 1/2 scram condition should exist but does not.

CRS reviews ITS section 3.3.1.1 and directs a 1/2 scram be inserted on the A side of RPS within 1 hour1.157407e-5 days 2.777778e-4 hours 1.653439e-6 weeks 3.805e-7 months .

Event 5: 12 Reactor Recirc Pump Motor Bearing High Temp / Vibration

The 12 Reactor Recirc pump motor will experience bearing high temperatures and subsequent vibration. Annunciator 4-C-24 (RECIRC PUMP MTR B HI VIBRATION) will alarm.

When vibrations exceed 3 mils the 12 Reactor Recirc pump will be shutdown. This will require a power reduction via lowering both recirc pump speed and inserting control rods to meet the requirements of power/flow map.

The CRS will recognize LCO Conditions 3.11.A (B), (C) are applicable at this time, when power is lowered below 90%.

Event 6: Group 1 Isolation / ATWS

A spurious Group 1 isolation (MSIV closure) will occur and an ATWS condition will result in the crew performing actions of EOP-2007, Failure to Scram.

After the initial actions of the EOP power leg are performed, the OATC will insert control rods and initiate SBLC.

The BOP will take actions to prevent injection into the RPV.

When all control rods are inserted, SBLC will be secured.

RPV water level will be returned to the normal band.
