Once Reactor Power is reduced to below 85% the SSF must be declared inoperable and therefore Tech Spec 3.10.1 applies.

Conditions A-E will be entered all of which have a 7 day completion time.

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 1 - 4) 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 lncore QPT exceeds +3.5 (due to misaligned control rod). (If the highest lncore 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 QPT restored within 24 hrs.

6. Limits And Precautions 6.1 This procedure contains activities that have potential to affect core reactivity by causing power transients ifICS NOT in Automatic. (R.M.)

6.2 The following Limits and Precautions are Reactivity Management related: (R.M.)

6.2.1 Small Rx Power changes should be expected for Valve Testing. Any Rx power change 2: +/- 3.0% from initial value is considered unexpected. (R.M.)

6.2.2 Small Rx Power changes should be expected for Valve Testing. For purpose of this procedure any Rx Power change>+/- 2.0% from initial value is considered test termination criteria.

Test will be terminated by activating "Abort Test" and PIP should be written to investigate problem. (R.M.)

6.2.3 If NI Power or CTPB increases 2: 5% within::; 5 minutes, fuel should be conditioned by holding CTP constant for> 10 minutes. (R.M.)

If NI Power or CTPB increases 2: 5% within ::; 5 minutes, notify Reactor Engineering and write PIP. (R.M.)

6.2.4 Small Rx Power changes should be expected for each movement test of a Turbine Valve. Allow sufficient time between each test for Rx Power to stabilize. (R.M.)

6.2.5 A potential failure mode exists with the Main Turbine Control Valve Fast Acting Solenoid Valve (F ASV) that could result in a reactivity management event ifthe (FSAV) Spool Piece fails to return to its normal position (de-energized state) after a Control Valve disc dump. (R.M.)

6.3 Failure of Stop Valve to "disc dump" could indicate an inoperable Stop Valve and should be evaluated by Engineering. {PIP 0-02-02750} {3}

6.4 Enclosure 13.1 "Stop Valve and Reheat/Intercept Valve Movement At Power" or Enclosure 13.2 "Control Valve Movement At Power" shall NOT be performed at< 85%

CTP since two closed control valves increase asymmetrical loading of turbine.

6.5 SV(s), RHSV(s), and IV(s) tests are performed between 87% and 90% CTP to minimize turbine asymmetrical loading and for Control Valve Position such that CV-4 is fully closed at start of test.

6.6 Turbine vibration amplitude changes up to 2 mils are expected during performance of Control Valve testing. Vibration levels should be monitored and appropriate action taken per OP/l/A/1106/001 (Turbine-Generator) as required.

PT!l!A/02901003 Page 4of6 6.7 All Turbine-Generator alarm limits should be followed while this procedure is being performed. OP/I/A/1106/00 I (Turbine-Generator) can be used as reference.

6.8 Control Valves, Reheat Stop Valves/Intercept Valves, and Stop Valves shall return to original position prior to starting next test.

6.9 Desired mode for MSRH is "feed mode" with pumps On or Off during this test.

7. Required Unit Status See initial conditions for each enclosure.

8. Prerequisite System Conditions See initial conditions for each enclosure.

9. Test Method 9.1 Testing performed using EHC HMI Panel.

9.2 Alternate methods to document valve movement are:

9.2. l Documenting all SV(s), RHSV/IV(s), and CV(s) closed following Reactor/Turbine-Generator trip or normal Unit shutdown.

9.2.2 Documenting SV(s), RHSV/IV(s), and CV(s) closed on Unit startup following performance of IP/O/B/02811002 (Turbine Electro-Hydraulic Control System Valve Stroke and JCS Feedback Testing and Calibration).

Enclosure 13.3 PT/l/A/0290/003 Turbine Valve Movement Page 1of3 Information

1. Initial Conditions None

2. Procedure This Enclosure contains sections which provide additional information concerning Turbine Valve Movement Test.

3. Description of Testing Procedure Purpose of PT/l/A/0290/003 is to test closing operation of:

Main Steam Stop Valves (SV)

Turbine Control Valves (CV)

Combined Reheat Stop Valves/Intercept Valves (RHSV/IV)

General Electric turbine missile probability calculations require minimum of quarterly full stroke testing of turbine valves to ensure the valves will close. {3}

This test requires Unit 1 CTP between 87-90% power. This power range is for Control Valve position.

Brief summary of Turbine Valve Test is as follows:

Each CV and each RHSV/IV are closed individually, then allowed to open.

SVI and SV3 are tested simultaneously.

SV2 and SV4 are tested simultaneously.

NI Power is observed during test. All normally observed Turbine Generator parameters shall be monitored. (R.M.)

During the performance of PT/I/ A/0290/003, failure of Stop Valve to "disc dump", could indicate an inoperable Stop Valve. {3}

Enclosure 13.3 PT!l/A/0290/003 Turbine Valve Movement Page 2of3 Information

4. Nuclear Safety Considerations This procedure contains activities that have potential to affect core reactivity by causing power transient ifICS NOT in Automatic. (R.M.)

Ensuring Unit l fuel fully conditioned per PT/O/A/1103/020 (Power Maneuvering Predictions) or allowable step change based on Unit I condition of fuel per PT/O/A/1103/020 (Power Maneuvering Predictions) >3% in:::; 5 minutes is to prevent exceeding maneuvering limits during the performance of the test. (R.M .) { 1}

5. Test Performance Information The following precautions are taken to prevent equipment or system concerns:

CTP > 85% prevents closure of two Control Valves simultaneously, assuring asymmetrical loading on Turbine is NOT increased.

CTP between 87% and 90% is high enough to limit asymmetrical loading of Turbine. SG tube damage from flow induced vibration is also prevented at this power range because of reduced steam flow to SGs.

SV testing is performed such that SVI and SV3 are tested simultaneously. SV2 and SV4 are tested simultaneously. SVI and SV3 are connected to different SGs. SV2 and SV4 are similarly connected. This test method maintains pressures and steam flows balanced in each SG while stroking valves.

Expected Rx Power changes during valve testing should be<+/- 3% NI Power. Test abort criteria of> +/- 2% Rx Power change is conservatively set to prevent exceeding allowable Rx Power change. (R.M.)

6. Test Acceptance Information For each Turbine Valve tested, the EHC Control systems executes a sequence of steps that strokes each valve towards the disk-dump position, initiates a disk-dump, confirms a disk-dump, and then returns the valve to its pre-test position.

During Turbine Valve testing, the EHC Control System monitors the progression through each test sequence and will indicate successful complication of each test sequence on the Valve Test screen.

Normal operation is for each test sequence to be satisfied and the EHC Control System will then indicate "Test Successful". However, if any test sequence is not completed or if the time between sequences exceeds a predefined limit, a Test Fail" indication will be received.

Enclosure 13.3 PT!l!A/02901003 Turbine Valve Movement Page 3of3 Information There are possible scenarios in which a "Test Fail" indication is received but the primary intent of the procedure is met. In addition, a "Test Fail" indication during Stop Valve testing could call into question their operable status. The following is a guide to assist Operations in determining ifthe primary intent of testing is met during Turbine Valve Movement Testing and if Stop Valve operable status is in question.

Primary Intent Applicable Turbine Valve If "Test Failed" Received Met If "Test Failed" received but valve Valve moves moved towards closed position and towards closed then returned to pre-test position, All Turbine Valves direction during document in PIP for ENG to evaluate test. and proceed on with additional testing.

Operable Status If "Confirm (Valve Name) Fast Applicable Turbine Valve in question Close Operation" NOT Received Notify ENG to investigate and determine operable status of Stop "Confirm (Valve Valve(s).

Crew Response:

Crew should perform Plant Transient Response (PTR)

SRO/OATC/

BOP

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

The BOP reports no valid runback and monitors RCS pressure and inventory.

OATC takes ICS to MANUAL and both FDW controllers to HAND.

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

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

ARG for 1SA-02/A-4 SRO/OATC 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 Tc's from being established causing high Quadrant Power Tilt values.

The SRO should direct a band for delta Tc's of O+/-2 degrees as he establishes bands for parameters being manually controlled.

SRO directs performance of AP/1/A/1700/028, ICS Instrument Failures. (see next page)

Description:

RCS Boration from CBAST in Automatic Time Position Applicant's Actions or Behavior OP/1/A/1103/004A, Encl 4.1 (RCS Bo ration From CB AST With CB AST Pump)

SRO/OATC NOTE:

OP/1/A/1103/004 (Soluble Poison Control) provides guidance for RCS boron change calculation or computer calculation for determining required volumes. (R.M.)

LOST 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 LOST contains =25 gallons of DW. {16}

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

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

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

50 gal of OW 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 (1A LETDOWN FILTER INLET)

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

1. Purpose To describe proper method for operating Turbine Generator.

2. Limits And Precautions {18}

2.1 Use of this procedure can affect core reactivity management due to changes in steam load. (R.M.)

2.2 When changing steam loads, monitor RCS temperatures to prevent exceeding limits.

2.3 Turbine should NOT be operated above 1200 rpm with back pressure> 5 inches Hg.

absolute.

2.4 Low Load Operation Limits:

2.4.1 Maintain Exhaust Hood temperatures:::; 175°F during low load operation.

With> 125°F Exhaust Hood temperatures increase load slowly until temperature falls below 125°F.

2.4.2 When exhaust hood temperature is 125°F or less, Turbine is available for load increase per OP/1/A/1102/004 (Operation At Power).

2.4.3 Operation below 5% load (45 MWe) should be at minimum to prevent moisture erosion.

2.4.4 Motoring of Generator is to be avoided.

2.5 At 1800 rpm, minimum Turbine oil cooler outlet temperature is 100°F. Oil cooler outlet temperature should be:::::: 90°F before accelerating above 100 rpm. Normal operating oil cooler outlet temperature is 1 l0°F to 120°F. {2}

2.6 Maximum oil temperature rise across journal bearing is 50°F. Any oil drain temperature

> 150°F is abnormal and should be reported to Unit Operations Manager or Operations Duty Engineer.

2.7 Maximum oil temperature rise across thrust bearing is 45°F. Maximum metal temperature is 190°F. Normal operating metal temperatures are 140°F to l 75°F for active plate and 125°F to 150°F for inactive plate.

2.8 Minimum allowed cold gas temperature is 30°C when Generator is online.

2.9 Do NOT exceed limits as shown on Enclosure 4.5 (Capability Curve). {48}

OP/l/A/1106/001 Page 3of6 2.10 No voltage should be placed on generator unless turbine is rotating at> 900 rpm and sufficient gas pressure is available for cooling.

2.11 If Generator is operated without field, Turbine should be immediately tripped off line and shut down for inspection.

2 .12 Fallowing trip out due to Differential Phase Relays, both armature and field windings should be meggered and otherwise inspected before attempting to resynchronize.

2 .13 If Turbine speed reaches 2010 rpm, during overspeed testing, notify Operator at Front Standard to manually trip Turbine. {35}

2.14 Turbine should NOT be rolled to speed and synchronized unless within following limits:

{7}

DIFF EXP between- 0.180 inches & + 0.130 inches.

ROTOR EXP between 0.05 inches & 01.865 inches.

2.15 Reduce Turbine Generator load at rate < 5% per minute (45 MWe/min) below

""'150 MWe.

2.16 Maximum allowable side to side differential temperature across Low Pressure Turbines is 50°F.

2.17 Load increases to rated load will be maintained within following limitations:

2.17.1 Rate of Change of First Stage Shell Inner Surface Temperature shall NOT exceed 150°F/Hr.

2.17.2 Above and to left of curve per Enclosure 4.4 (First Stage Metal Temperature Inner vs Percent Load).

2.17.3 First Stage Shell Inner and Outer Surface Temperature ~T should NOT exceed 75°F.

2.18 Control Valve Casing Inner and Outer Metal Temperature should NOT exceed Difference Limit.

2.19 Refer to Enclosure 4.6 (Oconee Generator Operating Limits) for Voltage, Current and Temperature Limits.

2.20 If unit is to be out of service for extended time period, bearing lubricating oil system should be operated for at least 112 hour0.0013 days 0.0311 hours 1.851852e-4 weeks 4.2616e-5 months per week to maintain protective surface oil film throughout lubrication system. Turbine should be put on turning gear about 5 minutes during each 1/2 hour periods.
