OSP-SF-00001 Rev. 040 Page 4 of 45 CONTINUOUS USE SHUTDOWN MARGIN CALCULATIONS 1.0 PURPOSE 1.1. To provide instructions for performing SHUTDOWN MARGIN (SDM) calculations. 1.2. To satisfy the following Tech Spec surveillances:

T/S SR 3.1.1.1

T/S SR 3.9.1.1 2.0 SCOPE This procedure is applicable for MODES 1 through 6. 3.0 ACCEPTANCE/FUNCTIONAL CRITERIA 3.1. In MODES 1 and 2, SDM shall be within the limits provided in the Core Operating Limits Report (COLR).

T/S ACT 3.1.4.A.1.1

T/S ACT 3.1.4.B.2.1.1

T/S ACT 3.1.4.B.2.3

T/S ACT 3.1.4.D.1.1 3.2. In MODE 1 and MODE 2 with Keff greater than or equal to 1.0, the SDM shall be within the limits provided in the COLR.

T/S ACT 3.1.6.A.1.1

T/S ACT 3.1.6.B.1.1 3.3. In MODE 1 and MODE 2 with any control bank not fully inserted, the SDM shall be within the limits provided in the COLR.

T/S ACT 3.1.5.A.1.1 OSP-SF-00001 Rev. 040 Page 5 of 45 CONTINUOUS USE 3.4. In MODE 2 with Keff less than 1.0, and MODES 3, 4, and 5, the SDM shall be within the limits provided in the COLR.

T/S LCO 3.1.1

T/S SR 3.1.1.1

T/S BSR 3.1.1.1

T/S APP 3.1.1 NOTE 3.5. In MODE 6, the boron concentrations of all filled portions of the Reactor Coolant System and the refueling pool that have direct access to the reactor vessel, shall be maintained within the limit.

T/S LCO 3.9.1

T/S SR 3.9.1.1

T/S ACT 3.9.2.A.3 4.0 PRECAUTIONS AND LIMITATIONS 4.1. During startup and/or power operations, the control bank insertion limits of COLR, Figure 2 of Curve Book, Figure 13-1 (COLR Figure 2), shall be maintained.

4.2. Many figures in the Curve Book are provided for BOL, MOL, and EOL conditions. BOL curves are generated for a burnup of 150 MWD/MTU (after xenon has reached equilibrium) and MOL curves are generated at 10000 MWD/MTU burnup. EOL curves are generated for design end of life, which varies from cycle to cycle. Design end of life may be obtained from Curve Book, Figure 5-4. Generally, better results will be obtained by interpolating between the two curves which bound the current burnup. However, it is also permissible to use the curve for the burnup nearest to the current burnup.

In addition, some data is provided as a function of power level. If power is not at a power level for which the data is provided, best results are obtained by interpolating between the two power levels which bound the current power. However, it is permissible to use data from the power level nearest the current power. 4.3. The PC Nuclear Design Report (PCNDR) may be used to obtain reactivity data instead of the Curve Book. Many Curve Book values at exact burnups are available using the PCNDR. The WINPCDNR is also available to obtain reactivity data. 4.4. When obtaining reactivity data from the Curve Book to manually perform a SDM calculation, the sign convention (+ or -) specified in the Curve Book should be neglected and the absolute value of the reactivity data should be recorded on Attachment 2, 3, or 4. The required sign convention is already provided on Attachments 2, 3, and 4 in parentheses by the recorded value.

OSP-SF-00001 Rev. 040 Page 6 of 45 CONTINUOUS USE 4.5. SDM shall be the instantaneous amount of reactivity by which the reactor is subcritical or would be subcritical from its current condition assuming all rod cluster control assemblies (RCCA's) are fully inserted except for the single RCCA of highest reactivity which is assumed to be fully withdrawn. With any RCCA not capable of being fully inserted, the reactivity of the RCCA must be accounted for in the determination of SDM. In MODES 1 and 2, the fuel and moderator temperatures are changed to the hot zero power temperatures. 5.0 PREREQUISITES None -END OF SECTION-

OSP-SF-00001 Rev. 040 Page 22 of 45 CONTINUOUS USE NOTE When preparing for a reactor startup, the Estimated Critical Position Calculation may dictate a lower boron concentration than that calculated in this Section. Since the ECP is a more accurate reactivity balance, a lower boron concentration is permitted. As long as the control rods are predicted to be above the Rod Insertion Limit and the ECP is current, a mode change will not occur during the dilution to the critical boron concentration. 6.10.11.

The available rod worth of Step 6.11.8 accounts for rods being inserted as deep as the RIL. If a misaligned rod is below the RIL, its full worth from the RIL position is not available for insertion. Therefore such rods should be accounted for in Step 6.11.9.b. IF an entire rod bank is below the RIL (i.e., with no misaligned rods), its full bank worth from the RIL position is NOT available for insertion. Therefore such banks should be accounted for in Step 6.11.10 rather than in Step 6.11.9.b. b. RECORD the number of INOPERABLE rods. c. RECORD the total rod worth by multiplying the number of INOPERABLE rods from Step 6.11.9.b by the worth of the most reactive rod from Step 6.11.9.a.

Flushing BTRS Demineralizers

Pressure testing BTRS Demineralizers

Immediate Boration

Establishing & Securing From Dry Layup in the CVCS Chiller Unit

Removing BTRS from Service for Maintenance

Restoring BTRS to Service 3.0 PRECAUTIONS AND LIMITATIONS 3.1. Precautions 3.1.1. The boric acid storage tank level should not be reduced below the minimum required by FSAR 16.1.2.6, if in MODES 1 through 4 or FSAR 16.1.2.5, if in MODES 5 and 6. Plant MODE Contained Volume (gal) % Level in One Tank 1, 2, 3, or 4 17,658 70 5 or 6 2,968 10 3.1.2. Whenever a difference of 50 ppm exists, the pressurizer spray should be operated by placing the backup heaters on to equalize the boron concentration in the RCS and pressurizer. 3.1.3. Prior to make up being added to the refueling canal, RCS or Spent Fuel Pool, with all four RCPs secured, recirculation flow should be checked through the RCS (RHR flow greater than or equal to 1000 gpm) or the concentration of the make up should be greater than or equal to 2000 ppm. 3.1.4. At all times when boration/dilution via BTRS is initiated or in progress, the Reactor Coolant Filter must be in service with BGV8421, CVCS RX CLNT FLTR BYP ISO, CLOSED, to prevent possible resin leakage from entering the RCS.

OTN-BG-00002 Rev. 041 Page 5 of 71 CONTINUOUS USE 3.1.5. When placing a BTRS bed into service after an extended period of time or when the bed boron concentration is suspect, letdown flow should be diverted to the RHUT until the desired trend in boron concentration is observed by the Boron Concentration Monitoring System, (BCMS), or chemistry sample. 3.1.6. The recirculation return line to the RWST is non-seismic. To ensure the RWST remains OPERABLE in MODES 1 through 4, no other systems, with the exception of the SI pumps in standby, are aligned to the RWST return header when performing Section 5.6 aligned to the RWST. [Ref: 6.2.13] 3.1.7. Prior to establishing M/U flow for flushing a BTRS Demineralizer bed, BG FY-111B, COMBINED M/U & BA COUNTER, must be reset and the counter set to the maximum amount of water that Radwaste can receive. It is important to stop letdown flow through the letdown reheat heat exchanger prior to stopping M/U flow. This will allow cooling of the letdown reheat heat exchanger. 3.1.8. During Reactor Makeup Control System operation, it is permissible to place one of the Boric Acid Transfer Pumps in Pull To Lock. This will allow for maintenance of level in one of the Boric Acid Storage Tanks to prevent Annunciator 37B, BA TKS LEV LO. 3.1.9. When setting BG FY-111B, COMBINED M/U & BA COUNTER, and BG FY-110B, BA COUNTER, allowances should be made in the setpoint to compensate for instrument inaccuracies and isolation valve closure times on total flow delivered. For instance, the accuracy of both the boric acid integrator BG FY-110B and the total makeup flow integrator BG FY-111B is +/- one count. This equates to +/- 0.1 gal for BG FY-110B and +/- 1.0 gal for BG FY-111B. Differences in setpoint and total flow delivered are also dependent on the amount of time it takes for valves to close and isolate flow once the integrator setpoint has been reached. 3.2. Limitations Under normal conditions, the RMCS should operate in the AUTOMATIC mode. When used in modes other than AUTOMATIC, the system should be returned to AUTOMATIC upon completion of the evolution. 3.3. General Notes 3.3.1. BG HC-387, BTRS DEMIN BYPASS CTRL, should be adjusted to maintain a constant flow through the BTRS Demineralizer beds. This will allow more accurate results to be obtained for operator aid development. 3.3.2. Demineralizer flushing may be stopped or interrupted as required by plant conditions. However, to minimize the frequency of flushing operations, the Demineralizer should be flushed for the duration determined by the BG System Engineer.

OTN-BG-00002 Rev. 041 Page 6 of 71 CONTINUOUS USE 3.3.3. A new BTRS Demineralizer bed should be flushed in accordance with OTN-BG-00001 ADD05, Operation of the BTRS Demineralizer System, prior to placing the bed into service for the first time. 3.3.4. The BTRS Chiller Unit and Pumps are normally NOT in service. a. The Service Water Inlet and Outlet Headers are in a dry lay-up condition until the Chiller Unit is required for service. This requires a fill and vent of service water headers prior to the Chiller Unit being placed in service. A dry lay-up condition requires the inlet and outlet service water isolation valves to be LOCKED CLOSED with various vents and drains OPENED. b. The Chill Water side of the BTRS Chiller is also placed in dry lay-up condition until the Chiller Unit is required for service. Power is removed from the pumps and chiller unit. Some drains and vents are left OPEN with FME screens installed. 3.3.5. During Startup testing of the BTRS system, the following noted items were documented:

a. Operation of BTRS in the Borate mode following an extended period of time in the Dilute mode can initially produce BTRS effluent of approximately 200 ppm greater than the RCS boron concentration. b. If the Demineralizers are saturated when boration begins, or if the Demineralizers have been recently flushed before starting a dilution, the maximum anticipated change in RCS boron concentration via BTRS is approximately 100 ppm. Under either condition, the maximum change will require 8-10 hours for the Demineralizers to become saturated. c. Demineralizer inlet temperature as indicated on BG TI-381, LTDN RH HX TUBE SIDE OUTLET TEMP CTRL TEMP IND, should go to between 40°F to 60°F within approximately 1 hour1.157407e-5 days 2.777778e-4 hours 1.653439e-6 weeks 3.805e-7 months after BTRS has been placed in the Dilute mode, when BTRS is originally at ambient conditions (80°F). This is due to the time required to cool down the associated heat exchangers and piping. d. Demineralizer inlet temperature, as indicated on BG TI-381, should go to between 135°F and 145°F within approximately 15 minutes after BTRS has been placed in the Borate mode, when BTRS is originally at ambient conditions (80°F). e. When BTRS is in the Borate mode for more than 30 minutes at a time, Demineralizer inlet temperature, as indicated on BG TI-381, may begin to oscillate +8 to -10°F from the setpoint value.

OTN-BG-00002 Rev. 041 Page 7 of 71 CONTINUOUS USE Step 3.3.5 Cont'd f. During Borate mode of operation, to prevent the Demineralizer inlet temperature from reaching the BTRS TEMP HI DIVERT alarm setpoint of 156°F or the BTRS TEMP HI alarm setpoint of 150°F, it may be necessary to lower the setpoint on BG TK-381A, LTDN DIVERT FLOW CTRL, to prevent the oscillations. 3.3.6. Attachment 4, Volume Control Tank Level Control System, provides information on the setpoints and controls of the VCT level. 3.3.7. Attachments 6 through 8 are provided to assist in normal shiftly dilutions/borations of the RCS. It is the intent that the cover page of this procedure and applicable Attachments 6, 7, or 8 be copied for the intended shiftly dilutions/borations discussed at the beginning of shift brief. Copies should be made of the quantity discussed for the incremental dilutions/borations during the shift. 4.0 PREREQUISITES 4.1. WHEN required, ENSURE the following:

Reactor Makeup Water System is available to supply the RMCS.

Sufficient boric acid of proper concentration is available to supply the RMCS.

The Service Water System is available to supply the CVCS Chiller Unit during BTRS operation.

The CVCS Chiller Surge Tank is within the normal operating range. 4.2. Prior to make up being added to the refueling canal, RCS or Spent Fuel Pool, with all four RCPs secured, MAKE a URO Log entry documenting that either recirculation flow through the RCS (RHR flow) is greater than or equal to 1000 gpm, or that the boron concentration of the make up is greater than or equal to 2000 ppm. 4.3. IF making up to the RWST per Section 5.6 in MODES 1 through 4, ENSURE no other systems, with the exception of the SI pumps in standby, are aligned to the RWST return header. -END OF SECTION-OTN-BG-00002 Rev. 041 Page 8 of 71 CONTINUOUS USE 5.0 PROCEDURE INSTRUCTIONS NOTE All control switches are on Panel RL001 or RL002 unless otherwise noted.

OSP-BG-P005B Rev. 048 Page 3 of 25 CONTINUOUS USE CENTRIFUGAL CHARGING PUMP B INSERVICE TEST - GROUP B 1.0 PURPOSE 1.1. This procedure demonstrates the Group B operational readiness of Centrifugal Charging Pump B (CCP B) per APA-ZZ-00356, Pump and Valve Inservice Testing Program. 1.2. This procedure performs the open testing of BGV0095, BGV0589, BGV0605 and the close testing of BGV0091. 1.3. This procedure obtains pump spin up time for use in ITP-ZZ-00004, Response Time Testing Program, on a 36 month cycle. 2.0 SCOPE 2.1. The Group B operational readiness of CCP B is proved by development of a differential pressure between 2400 and 2899 psid on a frequency described in APA-ZZ-00356, Pump and Valve Inservice Testing Program. 2.2. The following check valve tests are performed:

BGV0095, CCP B DISCH TO SEAL WTR HX CHECK - open safety test

BGV0589, CCP B DISCH TO SEAL WTR INJ FLTRS HDR CHECK - open safety test

BGV0605, CCP B DISCH BGFCV0121 UPSTEAM CHECK - open non-safety test

BGV0091,CCP A DISCH TO SEAL WTR HX CHECK - closed non-safety test 2.3. Pump spin up time is the elapsed time from initiation of the start signal to obtaining a discharge pressure greater than 2405 psig. This response time test is normally performed once per 36 months. 2.4. The Centrifugal Charging Pump B room cooler is checked and documented for an automatic start when the Centrifugal Charging Pump B is started.

OSP-BG-P005B Rev. 048 Page 4 of 25 CONTINUOUS USE 3.0 ACCEPTANCE CRITERIA 3.1. Pump Test Data 3.1.1. Differential pressure is within the Normal Range as specified on Attachment 2, System Performance Data Sheet, per T/S SR 3.5.2.4, T/S SR 3.5.3.1, FSAR 16.1.2.3.1, and FSAR 16.1.2.4.1. 3.1.2. The Centrifugal Charging Pump B Room Cooler automatically starts when the Centrifugal Charging Pump B is started within the requirements of ODP-ZZ-00002, Equipment Status Control. 3.1.3. If pump spin up time is measured, the pump obtains the required discharge pressure from initiation of start signal as specified on Attachment 2. This partially satisfies T/S SR 3.3.2 1.C#10, T/S SR 3.3.2 1.D#10, T/S SR 3.3.2 1.E#10, FSAR 16.3.2.1.1, and FSAR 16.3-2, Table items 2a, 3a and 4a. 3.2. Check Valve Tests 3.2.1. BGV0095, CCP B DISCH TO SEAL WTR HX CHECK, is demonstrated open by pump differential pressure being in the Normal Range as specified on Attachment 2. 3.2.2. BGHV8111, B CCP DISCH MINIFLOW TO SEAL WTR HX ISO, pipe temperature is in the Normal Range as specified on Attachment 2. 3.2.3. BGV0605, CCP B DISCH BGFCV0121 UPSTREAM CHECK, is demonstrated open by initiating flow through the normal charging header as specified on Attachment 2. 3.2.4. BGV0589, CCP B DISCH TO SEAL WTR INJ FLTRS HDR CHECK, is demonstrated open by passing the required seal injection flow as specified on Attachment 2. 3.2.5.

OSP-BG-P005B Rev. 048 Page 5 of 25 CONTINUOUS USE 4.0 PRECAUTIONS AND LIMITATIONS 4.1. If performing in MODE 1, 2, or 3, T/S LCO 3.5.2 and FSAR 16.1.2.4 are applicable. 4.2. If performing in MODE 4, 5 or 6, FSAR 16.1.2.3 is applicable. 4.3. If performing in MODE 4, T/S LCO 3.5.3 is applicable. 4.4. A pretest brief should be held to familiarize the appropriate personnel with the required testing this procedure dictates and with the Maintenance Rule Functionality requirements in Attachment 4. 4.5. IF the data falls in the Required Action Range:

4.5.1. The SM/CRS declares the component INOPERABLE and takes the required actions in accordance with Technical Specifications and APA-ZZ-00340, Surveillance Program Administration. 4.5.2. The SM/CRS checks the validity of the data (i.e., by immediately rerunning the test, evaluating test instruments and conditions, conferring with test personnel, or other methods). 4.6. When measured pump test parameters that fall outside the Normal Range have resulted from an identified systematic error such as improper system lineup or inaccurate instrumentation, the test shall be rerun after correcting the error. 4.7. If testing is terminated or temporarily postponed at some point prior to the locked valve being returned to its normal locked position, the altered valve shall be logged in the Locked Component Deviation List per ODP-ZZ-00004, Locked Component Control. 4.8. PBG05B, CCP B, should NOT be run at less than 60 gpm. 4.9. PBG05B, CCP B, should NOT be run at less than 130 gpm for more than 30 minutes. 4.10. RCP Seal injection flow must be maintained between 8 and 13 gpm for each RCP. 4.11. Prior to starting a CCP, the associated Auxiliary Lube Oil Pump should be started per OTN-BG-00001, Chemical And Volume Control System, to ensure proper CCP sleeve bearing lubrication is present before pump loading occurs. [Ref: 8.2.7] 4.12. After a CCP is secured, the associated Auxiliary Lube Oil Pump should be stopped per OTN-BG-00001, Chemical And Volume Control System. [Ref: 8.2.7] 4.13. If testing is required during Cold Shutdown, the reactor vessel should be open to atmosphere.

OSP-BG-P005B Rev. 048 Page 6 of 25 CONTINUOUS USE 4.14. If testing is required with the vessel head installed during Cold Shutdown, the discharge of the charging pump must NOT be opened unless transferring charging pumps for normal charging alignment. FSAR 5.2.2.10.4 [Ref: 8.1.13] 4.15. If CCP B has been made incapable of injection per T/S LCO 3.4.12, then CCP B should be aligned per OSP-BG-00002, Verify One Centrifugal Charging Pump Incapable Of Injection Into RCS. 4.16. If charging is required, then CCP A or the NCP should be in service supplying normal Charging/Seal Injection per OTN-BG-00001, Chemical And Volume Control System. 4.17. An FPIP (based on Master FPIP MFP-00826) should be implemented any time a CCP is run. This requires a Fire Watch to implement compensatory measures due to impact on capability of post fire safe shutdown. 4.18. After pump testing conditions are stable, the pump must be run for at least two (2) minutes prior to taking pump performance data. 5.0 PREREQUISITES 5.1. Initial Conditions 5.1.1.

OSP-BG-P005B Rev. 048 Page 12 of 25 CONTINUOUS USE NOTE Normally, the pipe temperature should rise to between 100 and 130°F and stabilize. If CCW temperature is below usual temperature due to cold weather, the pipe temperature may be as much as five (5) degrees below this normal range and is acceptable. [Ref: 8.2.6] CAUTION If pipe remains cool, it is an indication of no recirculation flow and the pump should be stopped immediately. If pipe gets over 160°F, it is an indication of not enough recirculation flow, the pump should be stopped and the recirculation flow path investigated. 6.1.24. At approximately five (5) minute intervals for the first 15 minutes of pump operation, MEASURE pipe temperature just upstream of BGHV8111, CCP B DISCH MINIFLOW ISO VLV, and RECORD on Attachment 2. NOTE Pressure indication may be subject to rapid fluctuations. If this occurs, BGV0093, CCP B SUCT BGPI0188 ROOT, should be slowly closed until readings stabilize prior to recording pressure. 6.1.25. OBTAIN suction pressure from BGPI0188, CCP PMP B SUCTION PRESS IND, and RECORD on Attachment 2. 6.1.26.

BGV0589 Check Valve Open Test 6.3.1. ENSURE CCP B is supplying normal charging/seal injection per OTN-BG-00001, Chemical And Volume Control System. CAUTION

IF BGV0100 is allowed to remain closed for more than two (2) minutes, unless Step 6.3.3.a is performed, the reduced charging flow may cause a decrease in pressurizer level that can reduce RCS pressure to less than the LCO 3.4.1.a DNB limit.

Energizing Pressurizer Heaters will cause an outsurge from the Pressurizer that may result in a reactivity change. 6.3.2. IF a VT2 inspection of BGV0100, CVCS SEAL WTR INJ FLTRS IN ISO, will be performed while it is closed, ENERGIZE a BU Heater group per OTN-BB-00005, Pressurizer and Pressurizer Pressure Control.

OSP-BG-P005B Rev. 048 Page 16 of 25 CONTINUOUS USE NOTE When closing BGV0100, the greatest decrease in RCP seal flow will occur near the end of valve travel. While closing BGV0100, if higher flow letdown orifice is in service and BG HC-182 is throttled closed to maintain seal flow greater than 32 gpm, Pressurizer level may be observed to lower with BGFCV0121 full open. While closing BGV0100 and opening BG HIS-8357B, it will be necessary to monitor and maintain the following parameters using BG HC-182 and BG FK-121 to keep Pressurizer and VCT levels relatively stable:

Seal flow between 32 and 52 gpm on BG FI-215A or BG FI-215B

Combined flow on BG FI-121A and BG FI-215A or BG FI-215B maintained greater than 70 gpm to meet CCP minimum flow requirements. When BGV0100 is closed BG FI-121A will indicate charging flow only, and BG FI-215A or BG FI-215B, will indicate RCP seal flow only.

Pressurizer pressure 2225 to 2250 psig

Letdown Regen HX outlet temperature less than 385 ºF on BG TI-127 6.3.3. PERFORM the following steps to provide RCP seal flow through the alternate seal injection line:

a. MONITOR and MAINTAIN parameters listed in the above note. b. Slowly OPEN BG HIS-8357B, CCP B TO RCP SEALS

. c. UNLOCK and CLOSE BGV0100, CVCS SEAL WTR INJ FLTRS IN ISO. d. WHEN BGV0100, CVCS SEAL WTR INJ FLTRS IN ISO, is fully closed, RECORD RCP seal flow using BG FI 215A, CHG PUMP TO RCP SEAL FLOW, or BG FI 215B, CHG PUMP TO RCP SEAL FLOW, on Attachment 2. e. Slowly OPEN BGV0100, CVCS SEAL WTR INJ FLTRS IN ISO. f. Slowly CLOSE BG HIS-8357B, CCP B TO RCP SEALS. g. WHEN Pressurizer level is restored to program, ADJUST BG HC-182, CHG HDR BACK PRESS CTRL, to attain 32 gpm RCP seal flow or as desired on BG FI-215A, CHG PUMP TO RCP SEAL FLOW, or BG FI-215B, CHG PUMP TO RCP SEAL FLOW.

OSP-BG-P005B Rev. 048 Page 24 of 25 CONTINUOUS USE Attachment 3 CCP B Suction Pressure Calculations Sheet 1 of 1 Per J-24BG40 and J-07P16, BG PI-188 is at 1976' 7 1/2". Instruction manual M-721-0093 gives Net Positive Suction Head (NPSH) required equals 16 feet. M-23BG02 gives pump suction nozzle elevation at 1979' 7". Pump can take suction from the RWST or the VCT. The VCT has the limiting suction pressure characteristics. J-U8000 gives the following setpoints:

VCT Hi Pressure Alarm (BG-PAHL-115) = 65 psig VCT Lo Pressure Alarm (BG-PAHL-115) = 5 psig VCT Hi Level Alarm (BG-LAHL-149) = 97%

VCT Lo Level Alarm (BG-LAHL-149) = 22%

Westinghouse Precautions, Limitations, and Setpoints document (PLS) gives BG- 8120, VCT relief valve, setpoint at 75 psig. M-23BG04 gives VCT full at 2013' 8 3/8". The PLS also states that BG LT-149 is calibrated to a 75" span extending from the lower tap to a point 75" above the lower tap. Per J-24BG12, the lower instrument tap is at 2003' 9 1/2". From this, 97% is calculated to be at 2009' 10 1/4" and 22% to be at 2005' 2". 0-150 psig

+/- 2% FS pressure gauges give

+/- 3 psig accuracy. Add or subtract this as appropriate. Using the above information:

Low Action Range From NPSH required 1979' 7" + 16' - 1976' 7 1/2" = 8.21 psig

-3.0 psig 5.21 psig <5.2 psig Low Alert Range From VCT low alarm for pressure and level 2005' 2" - 1976' 7 1/2" = 27' 2 1/2" =11.78 psig + 5 psig = 17.35 psig

OSP-BG-P005B Rev. 048 Page 25 of 25 CONTINUOUS USE Attachment 4 Maintenance Rule Functionality Brief Sheet 1 of 1

While Safety Systems are thought of as those systems designed to mitigate design basis accidents, not all mitigating systems have the same risk importance. Those systems that have a higher risk importance are monitored for unavailability time, which is when the system is not functional as related to Maintenance Rule unavailability indicator.

Actions taken to maintain system functionality such as taking credit for actions by the Reactor Operator in the Control Room or a stationed Maintenance Rule Dedicated Operator do NOT make the system operable. Crediting these actions only maintains Maintenance Rule Functionality so the system does not accrue Unavailability hours.

Actions may be credited if they are simple and may be performed in a short time frame. If actions are being credited, and if required to be relieved or leave the area, the operator involved must perform a turnover of the listed functionality actions in event of a valid demand of the system or secure from the test and restore system functionality.

Functionality Actions for OSP-BG-P005B:

Use of a Maintenance Rule Dedicated Operator:

When BG8483C, CCP B DISCH BGFCV0121 UPSTRM ISO, is closed, CCP B is NOT functional unless a Maintenance Rule Dedicated Operator is stationed in the vicinity of BG8483C to restore system to functional should a valid signal occur.

During restoration, the Maintenance Rule Dedicated Operator is released when BG8483C is opened and locked open.
