OSP-SF-00001 Rev. 040 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 3.9.1.1 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 Page 4 of 45 CONTINUOUS USE

OSP-SF-00001 Rev. 040 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 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 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.

Page 5 of 45 CONTINUOUS USE

OSP-SF-00001 Rev. 040 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.

OSP-SF-00001 Rev. 040 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. IF current boron concentration is NOT greater than or equal to one of the following AND a reactor startup is NOT anticipated within the next hour:

  • Boron concentration recorded in Step 6.10.8
  • Boron concentration calculated in the Estimated Critical Position Calculation (Refer To above note)

PRIOR to withdrawing shutdown banks, BORATE until the required concentration is obtained.

OSP-SF-00001 Rev. 040 6.11. At Power SDM Calculation NOTE At power SDM is normally maintained by ensuring rods are above the rod insertion limits. At power SDM calculation is normally performed only when one or more rods are INOPERABLE, misaligned, or NOT within the insertion, sequence or overlap limits.

6.11.1. IF desired, USE PC program OSPSF1 to calculate SDM in lieu of completing this Section.

6.11.2. INITIATE Attachment 4 and RECORD all data for this section on Attachment 4.

6.11.3. RECORD the indicated power level as follows:

a. IF power is greater than 20%, OBTAIN power level from one of the following:
  • Computer point REU1118 (i.e., REU1118 x 100% / 3565 MW)
  • The highest power range meter:
b. IF power if less than or equal to 20% power, OBTAIN power from the highest delta T indication:
  • BB TI-411A
  • BB TI-421A
  • BB TI-431A
  • BB TI-441A NOTE This calculation assumes that PZR boron concentration is equal to or greater than RCS boron concentration.

6.11.7. RECORD the corrected power defect by summing the redistribution allowance and voids reactivity in Step 6.11.6 and the total power defect in Step 6.11.5.

6.11.8. RECORD the available rod worth from Curve Book Table 1-8,Section II.

6.11.9. DETERMINE the Rods Correction for INOPERABLE Rods:

a. RECORD the most reactive rod's worth from Curve Book Table 1-8,Section II.

NOTE A rod is considered trippable if it was demonstrated OPERABLE during the last performance of T/S SR 3.1.4.2 and met the rod drop time criteria during the last performance of T/S SR 3.1.4.3 (T/S BACT 3.1.4.A.1.1).

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.

a. RECORD the RIL for the power level recorded in Step 6.11.3.
b. RECORD the current critical controlling control rod bank AND its height from one of the following:
  • The step counters
  • The plant computer
c. IF the current controlling control rod bank position from Step 6.11.10.b is above the RIL from Step 6.11.10.a, PERFORM the following (i.e., no correction is necessary for rod banks above the RIL):
1. Mark Steps 6.11.10.d through 6.11.10.g NA
2. Go To Step 6.11.10.h NOTE The integral rod worths are based on the bank height (either RIL or critical position) and the power level and burnup which exist for the current critical condition.
d. RECORD the integral rod worth obtained from PCNDR (WINPCNDR) for the associated RIL in Step 6.11.10.a.
e. RECORD the integral rod worth obtained from PCNDR (WINPCNDR) for the associated critical rod height in Step 6.11.10.b.
f. Subtract the critical rod worth in Step 6.11.10.e from the rod worth at RIL in Step 6.11.10.d.

NOTE This calculation allows for 10% rod worth uncertainty.

g. Multiply the results in Step 6.11.10.f by 1.10 to DETERMINE the rod worth correction for rod banks below the RIL.
h. RECORD the rod worth correction for rod banks per one of the following:
  • IF rod banks are below the RIL, RECORD the rod worth correction from Step 6.11.10.g.
  • IF rod banks are above the RIL, RECORD a rod worth correction of 0 pcm.

OTN-BG-00002 Rev. 041 REACTOR MAKEUP CONTROL AND BORON THERMAL REGENERATION SYSTEM 1.0 PURPOSE To provide instructions for the operation of the Reactor Makeup Control System (RMCS) and the Boron Thermal Regeneration System (BTRS).

2.0 SCOPE This procedure addresses all modes of RCS boration and dilution and also includes:

  • 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 Contained  % Level in MODE Volume (gal) 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.

Page 4 of 71 CONTINUOUS USE

OTN-BG-00002 Rev. 041 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.

Page 5 of 71 CONTINUOUS USE

OTN-BG-00002 Rev. 041 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 <br />2.777778e-4 hours <br />1.653439e-6 weeks <br />3.805e-7 months <br /> 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.

Page 6 of 71 CONTINUOUS USE

OTN-BG-00002 Rev. 041 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.

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.

Page 15 of 25 CONTINUOUS USE

OSP-BG-P005B Rev. 048 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 level within 5 % of program
  • 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 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 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.
