Monitor the plant

Respond to direction from the SRO

Provide Peer Checks when requested The BOP should use the in progress procedure PTI1/A102901003 (Turbine SRO/BOP Valve Movement) Enclosure 13.2, Control Valve Movement At Power, at step 2.6 to test CV1:

2.6.1 IF required, select Control Valve 1 & 2 Tesf.

2.6.2 Verify Test Permissive is ON.

2.6.3 Record CV1 pretest position: % Open.

2.6.4 Select Initiate Test for Control Valve 1 Test.

NI POWER changes > 2%. (R.M.)

ICS Turbine Master trips to HAND. (R.M.)

Turbine vibration> 10 mils for > 5 seconds.

CAUTION: If CV1 remains in the closed position with the Test Failed indication ON, initiating Abort Test could result in a reactivity management event. (R.M.)

Description:

PT111N02901003, End. 13.2 (Control Valve Movement at Power) in progress:

testing Cvi Time Position Applicants Actions or Behavior Crew Response: (Cont.)

SRO/BOP NOTE: It a Control Valve remains closed after it has disc-dump, it may start going open at any time (i.e. 1 mm, 5 mm, 1 hour1.157407e-5 days 2.777778e-4 hours 1.653439e-6 weeks 3.805e-7 months ,...). When the Control Valve starts going back open it will open at its normal rate. No transients are expected during this scenario since the EHC Control System will simply continue with the test logic and return the Control Valve to its normal position at the normal controlled test rate.

2.6.7 IF Test Failed is ON AND CV1 remains closed perform the following:

Do NOT select Abort CV1 Test. (R.M.)

Notify WCC & Engineering that the (FASV) for the Control Valve under test is stuck in the energized state.

Booth Cue: As the Standby EHC pump is being secured, FIRE TIMER 2 to initiate Event 2.

NOTE: Control Valves which are not in their normal position could result in asymmetrical loading on the Turbine bearings.

Monitor Turbine Vibrations closely if in this abnormal state.

2.6.8 Perform EITHER for CV1:

A. Verify Test Successful indicated for CV1.

B. IF Test Successful NOT indicated for CV1, verify CV1 moved towards closed position.

2.6.9 Verify CV1 test indicator reset.

2.6.10 Verify CV1 within +/- 5.0% of pretest position.

2.6.11 Perform the following:

Verify acceptance criteria met

IE acceptance criteria NOT met, notify SRO Examiners Note: Per section 11.2, acceptance criteria is met if CV1 Test Successful indication occurs and the CV returns to within 5% of fully open. Acceptance criteria will be met.

2.7 IF desired:

Investigate and repair the failed RCS temperature instrumentation.

BOP 4. PERFORM an instrumentation surveillance using applicable table in End 5.2 (ICS Instrument Surveillances) for the failed instrument.

Examiner Note: This step will require the BOP to refer to Table 1 (RCS Temperature) of Enclosure 5.2 and determine if the surveillance for SR 3.4.1.2 can be met as it is written with the failed temperature instrument.

Based on plant response to the failure the BOP will determine either:

1. The surveillance is not required to be met due to plant conditions

2. The surveillance can be met as written

Crew Response:

SRO/BOP/ Crew should perform Plant Transient Response (PTR) and determine that no OATC manual FDW adjustments are required and that a runback condition exists but due to ICS being in manual it is not occurring.

OATC reports to the SRO reactor power level and direction of movement.

The BOP reports expected AUTO Runback did not occur, and monitors RCS pressure and inventory and inserts Control Rods as needed.

The OATC will adjust FDW and/or control rods as necessary to restore reactor power to the desired control band.

SRO should enter AP/1/A/1700/0O1 (Unit Runback)

AP/1 IA/i 700/00 1 4.1 GO TO the most limiting section per the following table:

2 IAAT more than one control rod is dropped or misaligned 6.5% (9) from the group average, THEN trip the Rx.

NOTE NIs should NOT be calibrated per guidelines contained in OP/i/All 102/004 (Operation at Power) due to actual power re-distribution within the core as a result of a dropped/misaligned rod.

TS 3.1.4 (Control Rod Group Alignment Limits), Condition A applies which provides 1 hr to restore alignment or verify SDM and be below 60%in2hrs

TS 3.1.5 (Safety Rod Position Limits), Condition A applies (Safety rods are in Groups 14) which requires verification of SDM and declaring the associated rod inoperable within 1 hr.

TS 3.2.3 (Quadrant Power Tilt), Condition A applies when Incore QPT exceeds ÷3.5 (due to misaligned control rod). (If the highest Incore QPT exceeds ÷7.11 then Condition B would apply) The power reduction required by Condition A will already be met due to the reduced power level at turnover. RPS trip setpoints must be reduced within 10 hrs and OPT restored within 24 hrs.

Crew Response:

When the Statalarms are received, the candidates should utilize the Plant Transient Response (PTR) process to stabilize the plant, which should include:

OATC o lOS to HAND (Feedwater Masters and Control Rods BOP o Inserting Control Rods as needed to control RCS pressure (Performed by the BOP)

OATC o Decreasing or re-ratioing feedwater to control Reactor power and delta Tcold (Performed by the OATC (CT-2)

SRO may direct the OATC to perform the actions of the ARG for 1 SA-02/A-4 SRO/OATC statalarm, but probably will move directly from PTR to AP/28.

ARG for 1SA-02/A-4 3.1. Ensure reactor power is reduced below the flux to flow minus imbalance trip ratio.

3.2. Ensure feedwater demand re-ratios properly.

EXAMINER NOTE: This failure will cause FDW flow to re-ratio. IF the crew immediately recognizes that it is in instrument failure and not an actual loss of flow then they may choose to adjust FDW and therefore prevent high delta Tcs from being established causing high Quadrant Power Tilt values.

The SRO should direct a band for delta Tcs of 0+/-2 degrees as he establishes bands for parameters being manually controlled.

Description:

RCS Boration from CBAST in Automatic Time Position

[ Applicants Actions or Behavior OP/i/Nil 03/004A, End 4.1 (RCS Boration From CBAST With CBAST Pump)

BOP During this activity, the BOP will be performing Peer Checks as required and responding to direction from the SRO when needed.

NOTE:

OP/i/Ni 103/004 (Soluble Poison Control) provides guidance for RCS boron change calculation or computer calculation for determining required volumes. (R.M.)

LDST temperature may increase from adding CBAST because of CBAST temperature.

50 gal flush must be performed to ensure calculated volume of CBAST is added.

Main process piping between CBAST and LDST contains 25 gallons of DW. {16}

If RCS boration is for a Forced Outage, targeted boron should not exceed 200 ppm above the required SDM to prevent excessive RCS boration.

The 200 ppm above required SDM will borate the Pressurizer to the required SDM since the Pressurizer usually lags the RCS by approximately 200 ppm.

Section 2: Procedure OATC 2.1 Determine required volume of CBAST needed for desired RCS boron changes. (R.M.)

50 gal of DW added due to flushing must be included in determination

Volume required gallons.

2.2 CBAST required volume approved (SRO). (R.M.)

NOTE:

Placing an idle Letdown Filter in service can change RCS boron by adding 60 gals of water to RCS at different boron (negligible for RCS boration). (R.M.)

2.3 IF two Letdown Filters are available, perform the following:

Ensure open 1HP-17 (iA LETDOWN FILTER INLET)

Ensure open 1HP-i8 (18 LETDOWN FILTER INLET) 2.4 Ensure open 1 CS-64 (CBAST OUTLET).

2.5 Open 1 CS-72 (CBAST Header to Letdown Filter Inlet). (A-2 LDST Hatch area)

CT-2 Manual actuation of AFIS must occur within 10 minutes of the Main Steam Line Break.

(Page 24)

CT-3 MU/HPI flow must be throttled to prevent overpressurizing the RCS when SCM exists by keeping the RC pressure below the RV P-T limit. This is accomplished by maintaining Pressurizer Level <400 inches. HPI flow must be maintained within acceptable operational bounds. This requires maintaining HPI flow greater than the minimum allowable pump flow rate and less than the pump runout flow rate. (Page 32)
