S ATTACHMENT 1 Evaluation of Proposed Changes In accordance with 10 CFR 50.90, "Application for amendment of license or construction permit," Exelon Generation Company, LLC (EGC) is requesting an amendment to Facility Operating License Nos. NPF-72 and NPF-77 for Braidwood Station, Units 1 and 2, respectively, and NPF-37 and NPF-66 for Byron Station, Units 1 and 2, respectively. The proposed amendment removes time, cycle, or modification-related items and typographical errors from the Operating Licenses and Technical Specifications at both stations. The time, cycle, and modification-related items have been implemented or superseded, are no longer applicable, and no longer need to be maintained in their associated Operating Licenses or Technical Specifications.
Braidwood Station Unit 1 Facilitv Operatinq License Delete Unit 1 Facility Operating License condition (OLC) 2.C.4, "Initial Startup Test Program,"
since the license condition has been satisfied. This OLC required EGC to report any changes to the Initial Test Program described in Chapter 14 of the Final Safety Analysis Report (FSAR) within one month of such change. The initial startup test program is complete and no further changes can be made.
Delete Unit 1 Facility Operating License OLC 2.C.5, "Regulatory Guide 1.97 Revision 2 Compliance." Operating License OLC 2.C.5 required EGC to submit a report and schedule for implementation within six months of NRC approval of the Detailed Control Room Design Review (DCRDR). EGC proposes to delete this OLC since the action has been completed. EGC's Final Report for Regulatory Guide 1.97 compliance was transmitted via a letter from S. C.
Hunsader (Commonwealth Edison Company) to T. E. Murley (NRC) dated September 1, 1987 (Reference 1).
Delete an exemption from the requirements of Appendix J to 10 CFR 50 concerning containment air locks from section 2.D. The need for this exemption was eliminated following the issuance of Amendment 73 (10 CFR 50, Appendix J, Option B), which was issued on April 4, 1996 (Reference 2). This specific exemption no longer needs to be included in the Operating License.
Delete Attachment 1 to the Unit 1 Facility Operating License, "Work Items to be completed." refers to letters to the NRC from Commonwealth Edison Company (ComEd) detailing the operation and testing of the Auxiliary Building Ventilation (VA) System during Unit 1 startup and operation, and Unit 2 construction. Construction is complete on both units at Braidwood Station and the VA System is fully operational. Therefore, Attachment 1 no longer needs to be included in the Braidwood Station Unit 1 Facility Operating License.

Braidwood Station Unit 2 Operating License ATTACHMENT 1 Evaluation of Proposed Changes Delete Unit 2 Facility Operating License OLC 2.C.4, "Initial Startup Test Program," since the OLC has been satisfied. This OLC required EGC to report any changes to the Initial Test Program described in Chapter 14 of the FSAR within one month of such change. The initial startup test program is complete and no further changes can be made.
Delete an exemption from the requirements of Appendix J to 10 CFR 50 concerning containment air locks from section 2.D. The need for this exemption was eliminated following the issuance of Amendment 73 (10 CFR 50, Appendix J, Option B), which was issued on April 4, 1996 (Reference 2). This specific exemption no longer needs to be included in this section of the Operating License.
Delete a time-related specific exemption regarding the requirements of 10 CFR 50.49(f) and 10 CFR 50.49(j) from section 2.D. This exemption was required until the startup following the Braidwood Station, Unit 2 surveillance outage that was scheduled in January 1989. This outage was completed as planned; therefore, this exemption is no longer required and can be removed from this section of the Operating License.
Delete the Unit 2 Facility Operating License Attachment 1, "Work Items to be completed." is listed as an attachment in the Unit 2 Facility Operating License; however, does not physically exist for Unit 2. Therefore, the reference to Attachment 1 can be deleted from the list of attachments in the Braidwood Station Unit 2 Facility Operating License.
Braidwood Station TS Table of Contents Revise the Braidwood Station TS Table of Contents. The proposed change revises the Table of Contents by deleting the listings of TS Tables and TS Figures from the Table of Contents. The Tables and Figures are not required to be listed separately in the Table of Contents according to NUREG-1431, Revision 3.0, "Standard Technical Specifications Westinghouse Plants," dated June 2004.
Braidwood Station TS 3.3.1. "FITS Instrumentation" Revise TS 3.3.1, "FITS Instrumentation," Condition N, Required Action Note. The proposed change corrects an editorial oversight in the nomenclature and structure of the Condition N Required Action Note. The change deletes the number of the Note (i.e., "1."), changes "Notes" to "Note", and removes an extra blank line in the Note. This editorial oversight was inadvertently introduced by Amendment 148 (Reference 3).

ATTACHMENT 1 Evaluation of Proposed Changes Braidwood Station TS Surveillance Requirements (SR) 3.7.2.1 and SR 3.7.2.2 Revise TS 3.7.2, "Main Steam Isolation Valves," for Braidwood Station. EGC is requesting deletion of Note 2 from both SR 3.7.2.1 and SR 3.7.2.2, as the requirements imposed by these Notes which were added in Amendment 119 (Reference 4) have been implemented, the SRs are currently being met, and no longer need to be modified by these Notes.
Braidwood Station TS 3.7.8, "Essential Service Water (SX) System" Revise TS 3.7.8 for Braidwood Station. EGC is requesting the deletion of a Note from Condition A, and the deletion of Condition B in its entirety from TS 3.7.8. Maintenance activities (i.e.,
replacement of the SX pump suction isolation valves), as discussed in TS Amendment 130 (Reference 5), necessitated the addition of the Note in Condition A, and the insertion of Condition B. These maintenance activities were completed during Unit 2 Refueling Outage 11 as scheduled ; therefore, the Condition A Note, and Condition B in its entirety, no longer need to be maintained in TS 3.7.8. This revision will result in various editorial and formatting changes.
Braidwood Station Unit 1 and Unit 2 Facility Operating License Appendix C "Additional License Conditions" Revise the Unit 1 and Unit 2 Facility Operating License Appendix C to delete items that have been satisfied and are no longer required. Specifically, EGC is proposing the deletion of all Unit 1 and Unit 2 Operating License Appendix C items associated with License Amendments 98 (Reference 6) and 113 (Reference 7). The Conditions associated with Amendment 98 were implemented within 180 days of the issuance of Amendment 98 which was issued on December 22, 1998. The Conditions associated with Amendment 113 are related to power uprate activities and have been completed as documented in References 8, 9, 10, and 11. Therefore, these additional conditions have been satisfied and no longer need to be tracked in the Facility Operating License.

Boron Station TS Table of Contents Bvron Station TS 3.3.1 "FITS Instrumentation" ATTACHMENT 1 Evaluation of Proposed Changes Revise the Byron Station TS Table of Contents. The proposed change revises the Table of Contents by deleting the listings of TS Tables and TS Figures from the Table of Contents. The Tables and Figures are not required to be listed separately in the Table of Contents according to NUREG-1431, Revision 3.0, "Standard Technical Specifications Westinghouse Plants," dated June 2004.
Revise TS 3.3.1, "FITS Instrumentation," Condition N, Required Action Note. The proposed change corrects an editorial oversight in the nomenclature and structure of the Condition N Required Action Note. The change deletes the number of the Note (i.e., "1."), changes "Notes" to "Note", and removes an extra blank line in the Note. This editorial oversight was inadvertently introduced by Amendment 153 (Reference 3).
Boron Station TS Surveillance Requirements (SR)3.7.2.1 and SR 3.7.2.2 Revise TS 3.7.2, "Main Steam Isolation Valves," for Byron Station. EGC is requesting deletion of Note 2 from both SR 3.7.2.1 and SR 3.7.2.2, as the requirements imposed by these Notes which were added in TS amendment 124 (Reference 4) have been implemented, the SRs are currently being met, and no longer need to be modified by these Notes.
Bvron Station TS 3.7.8, "Essential Service Water (SXLSvstem" Revise TS 3.7.8 for Byron Station. EGC is requesting the deletion of a Note from Condition A, and the deletion of Condition B in its entirety from TS 3.7.8. Maintenance activities (i.e.,
replacement of the SX pump suction isolation valves), as discussed in TS Amendment 136 (Reference 5), necessitated the addition of the Note in Condition A, and the insertion of Condition B. These maintenance activities were completed during Unit 1 Refueling Outage 13 as scheduled ; therefore, the Condition A Note, and Condition B in its entirety, no longer need to be maintained in TS 3.7.8. This revision will result in various editorial and formatting changes.

ATTACHMENT 1 Evaluation of Proposed Changes Byron Station TS 3.7.15, TS 3.7.16 and TS 4.3.1 Revise TS 3.7.15, TS 3.7.16, and TS 4.3.1 at Byron Station. The proposed revision removes all references to Joseph Oat spent fuel pool storage racks in these TS and their associated Bases.
The Joseph Oat spent fuel storage racks have been replaced with Holtec spent fuel storage racks as of January 1, 2001. Since the Joseph Oat spent fuel storage racks are no longer installed at Byron Station, the removal of these references is editorial only and will delete wording that is no longer required. The revisions will result in various editorial and formatting requirements, and as a result of the proposed revision to TS 3.7.16, SR 3.7.16.3, and existing Figures 3.7.16-1, 3.7.16-2, and 3.7.16-3 will be deleted in their entirety. Figure 3.7.16-4 will be renumbered to Figure 3.7.16-1.
This change is not proposed for Braidwood Station, as the TS for Braidwood Station were previously amended to remove reference to Joseph Oat fuel storage racks under amendment 145 (Reference 12).
Byron Station Unit 1 and Unit 2 Facility Operating License Appendix C, "Additional License Conditions" Revise the Unit 1 and Unit 2 Facility Operating License Appendix C to delete items that have been satisfied and are no longer required. Specifically, EGC is proposing the deletion of all Unit 1 and Unit 2 Operating License Appendix C items associated with License Amendments 106 (Reference 6) and 119 (Reference 7). The Conditions associated with Amendment 106 were implemented within 180 days of the issuance of Amendment 106 which was issued on December 22, 1998. The Conditions associated with Amendment 119 are related to power uprate activities and have been completed as documented in References 11, 13, and 14.
Therefore, these additional conditions have been satisfied and no longer need to be tracked in the Facility Operating License.
3.0 BACKGROUND
Historically, conditions, exceptions, or exemptions that are date, cycle, or modification-related have been tracked in the Facility Operating License. Over time, the actions or requirements that these items contain are implemented, and the issues no longer need to be tracked in the Facility Operating License. In an effort to clarify, and avoid any confusion regarding the current requirements contained in the Operating License, EGC is proposing the administrative removal of these items from the Operating License and TS for Braidwood and Byron Stations.
Page 6 of 11
4.0 TECHNICAL ANALYSIS
All proposed changes are administrative in nature and require no technical analysis.
5.0 REGULATORY ANALYSIS
ATTACHMENT 1 Evaluation of Proposed Changes 5.1 No Significant Hazards Consideration In accordance with 10 CFR 50.90, "Application for amendment of license or construction permit," Exelon Generation Company, LLC (EGC) is requesting an amendment to Facility Operating License Nos. NPF-72 and NPF-77 for Braidwood Station, Units 1 and 2, respectively, and NPF-37 and NPF-66 for Byron Station, Units 1 and 2, respectively. The proposed amendment provides for the administrative removal of time, cycle, or modification-related items from the Operating Licenses at both stations. These items have been implemented or superseded, are no longer applicable, and therefore, no longer need to be maintained in their associated Operating License.
According to 10 CFR 50.92, "Issuance of amendment," paragraph (c), a proposed amendment to an operating license involves no significant hazards consideration if operation of the facility in accordance with the proposed amendment would not:
Involve a significant increase in the probability or consequences of an accident previously evaluated ; or Create the possibility of a new or different kind of accident from any accident previously evaluated ; or Involve a significant reduction in a margin of safety.
(1)
(2)
(3)
In support of this determination, an evaluation of each of the three criteria set forth in 10 CFR 50.92 is provided below regarding the proposed license amendment.
Page 7 of 11
ATTACHMENT 1 Evaluation of Proposed Changes 1.
Does the proposed amendment involve a significant increase in the probability or consequences of an accident previously evaluated?
Response : No The initial conditions and methodologies used in the accident analyses remain unchanged. The proposed changes do not change or alter the design assumptions for the systems or components used to mitigate the consequences of an accident. Therefore, accident analyses results are not impacted.
All changes proposed by EGC in this amendment request are administrative in nature, and are removing one-time requirements that have been satisfied or items that are no longer applicable. There are no physical changes to the facilities, nor any changes to the station operating procedures, limiting conditions for operation, or limiting safety system settings.
Based on the above discussion, the proposed changes do not involve a significant increase in the probability or consequences of an accident previously evaluated.
- 2. Does the proposed amendment create the possibility of a new or different kind of accident from any accident previously evaluated?
Response : No None of the proposed changes affect the design or operation of any system, structure, or component in the plant. The safety functions of the related structures, systems, or components are not changed in any manner, nor is the reliability of any structure, system, or component reduced by the revised surveillance or testing requirements. The changes do not affect the manner by which the facility is operated and do not change any facility design feature, structure, system, or component. No new or different type of equipment will be installed. Since there is no change to the facility or operating procedures, and the safety functions and reliability of structures, systems, or components are not affected, the proposed changes do not create the possibility of a new or different kind of accident from any accident previously evaluated.
Based on this evaluation, the proposed changes do not create the possibility of a new or different kind of accident from any accident previously evaluated.
Page 8 of 11
Response : No ATTACHMENT 1 Evaluation of Proposed Changes
- 3. Does the proposed amendment involve a significant reduction in a margin of safety?
The proposed changes to the Facility Operating Licenses and TS are administrative in nature and have no impact on the margin of safety of any of the TS. There is no impact on safety limits or limiting safety system settings. The changes do not affect any plant safety parameters or setpoints. The Operating License Conditions have been satisfied as required. There are no changes to the conditions themselves.
Based on this evaluation, the proposed change does not involve a significant reduction in a margin of safety.
Therefore, EGC concludes that the proposed changes do not involve a significant hazards consideration under the criteria set forth in 10 CFR 50.92(c).
5.2 Applicable Regulatory Requirements/Criteria 10 CFR 50.36 details the information that must be included in each station's TS. The proposed changes modify or delete time, cycle, or modification-related items that have been implemented or superseded, and are no longer applicable. The proposed changes have no impact on current Safety Limits, Limiting Safety System Settings, Limiting Control Settings, Limiting Conditions for Operation, Surveillance Requirements, Design Features, or Administrative Controls. Therefore, EGC concludes that the methods used to comply with 10 CFR 50.36 are not modified by the proposed changes, and the requirements continue to be met.
In conclusion, based on the considerations discussed above, (1) there is reasonable assurance that the health and safety of the public will not be endangered by operation in the proposed manner, (2) such activities will be conducted in compliance with the Commission's regulations, and (3) the issuance of the amendment will not be inimical to the common defense and security or to the health and safety of the public.
6.0 ENVIRONMENTAL CONSIDERATION
Portions of the proposed amendment change a requirement with respect to installation or use of a facility component located within the restricted area, as defined in 10 CFR 20, "Standards for protection against radiation," or would change an inspection or surveillance requirement.
However, the proposed amendment does not involve (i) a significant hazards consideration, (ii) a significant change in the types or significant increase in the amounts of any effluent that may be released offsite, or (iii) a significant increase in individual or cumulative occupational radiation exposure. Accordingly, the proposed amendment meets the eligibility criterion for categorical exclusion set forth in paragraph (c)(9) of 10 CFR 51.22, "Criterion for categorical exclusion; identification of licensing and regulatory actions eligible for categorical exclusion or otherwise not requiring environmental review." Therefore, in accordance with 10 CFR 51.22(b),
Page 9 of 11
ATTACHMENT 1 Evaluation of Proposed Changes no environmental impact statement or environmental assessment need be prepared in connection with the proposed amendment.
Portions of the proposed amendment are confined to (i) changes to surety, insurance, and/or indemnity requirements, or (ii) changes to recordkeeping, reporting, or administrative procedures or requirements. Accordingly, these portions of the proposed amendment meet the eligibility criterion for categorical exclusion set forth in 10 CFR 51.22(c)(10). Therefore, pursuant to 10 CFR 51.22(b), no environmental impact statement or environmental assessment need be prepared in connection with these portions of the proposed amendment.

BASES SURVEILLANCE SR 3.7.2.1 REQUIREMENTS This SR verifies that MSIV closure time is <_ 5 seconds.
The MSIV closure time is assumed in the accident and containment analyses.
This Surveillance is normally performed upon returning the unit to operation following a refueling outage.
Based on ASME Code Section XI (Ref. 5), the MSIVs are not closure time tested at power.
The Frequency is in accordance with the Inservice Testing Program.
This test is conducted in MODE 3 with the unit at ure and pressure.
This SR is modified by allows entry into and operation in MODE 3 1 prior o per orming the SR.
This allows a delay of testing until MODE 3, to establish conditions consistent with_ those under which the acceptance criterion was qenerated.
r SR 3.7.2.2 This SR verifies that each MSIV can close on an actual or simulated actuation signal.
This Surveillance is normally performed upon returning the unit to operation following a refueling outage.
The frequency of MSIV testing is every 18 months.
The 18 month Frequency for testing is based on the refueling cycle.
Operating experience has shown that these components usually pass the Surveillance when performed at the 18 month Frequency.
Therefore, this a., ,tn T~ ;n R,,.+n Frequency i s acceptable from a reliability standpoint.
Ea Note a him avvtc This SR is modified b'y t e

BASES APPLICABILITY In MODES 1, 2, 3, and 4, the unit-specific SX System is a normally operating system that is required to support the OPERABILITY of the equipment serviced by the SX System and required to be OPERABLE in these MODES.
ACTIONS A.1 While a specific unit is in MODES l, 2, 3, or 4, the opposite-unit SX System must be available (independent of the opposite unit's MODE or condition) for unit-specific support.
This minimizes the risk associated with loss of all unit-specific SX.
In MODES 5 and 6 the OPERABILITY requirements of the unit-specific SX System are determined by the systems it supports and there are no opposite-unit SX System requirements.
BRAIDWOOD - UNITS 1 & 2 B 3.7.8 - 4 SX System B 3.7.8 If one unit-specific SX train is inoperable, action must be taken to restore OPERABLE status within 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br />.
In this Condition, the remaining OPERABLE SX train is adequate to perform the heat removal function.
However, the overall reliability is reduced because a single failure in the OPERABLE SX train could result in loss of the SX System function in the short term.
The 72 hour8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br /> Completion Time is based on the redundant capabilities afforded by the OPERABLE train, and the low probability of a DBA occurring during this time period.

Ref this cem Iin to 11 Required Action A.1 is modified by two Notes.
The first Note indicates that the applicable Conditions and Required Actions of LCO 3.8.1, "AC Sources-Operating," should be entered if an inoperable SX train results in an inoperable emergency diesel generator.
The second Note indicates that the applicable Conditions and Required Actions of LCO 3.4.6, "RCS Loops-MODE 4," should be entered if an inoperable SX train results in an inoperable decay heat removal train.
These are exceptions to LCO 3.0.6 and ensure the proper actions are taken for these components.

If the opposite-unit SX train is not OPERABLE for unit-specific support, action must be taken to restore OPERABLE status within 7 days.
In this Condition, if a complete loss of unit-specific SX were to occur, the SX System function would be lost.
The 7 day Completion Time is based on the capabilities of the unit-specific SX System and the low probability of a DBA with a loss of all unit-specific SX occurring during this time period.
If the unit-specific SX train or the opposite-unit SX train cannot be restored to OPERABLE status within the associated Completion Time, the unit must be placed in a MODE in which the LCO does not apply.
To achieve this status, the unit must be placed in at least MODE 3 within 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br /> and in MODE 5 within 36 hours4.166667e-4 days <br />0.01 hours <br />5.952381e-5 weeks <br />1.3698e-5 months <br />.
The allowed Completion Times are reasonable, based on operating experience, to reach the required unit conditions from full power conditions in an orderly manner and without challenging plant systems.

BASES APPLICABILITY In MODES l, 2, 3, and 4, the unit-specific SX System is a normally operating system that is required to support the OPERABILITY of the equipment serviced by the SX System and required to be OPERABLE in these MODES.
ACTIONS A. l While a specific unit is in MODES l, 2, 3, or 4, the opposite-unit SX System must be available (independent of the opposite unit's MODE or condition) for unit-specific support.
This minimizes the risk associated with loss of all unit-specific SX.
In MODES 5 and 6 the OPERABILITY requirements of the unit-specific SX System are determined by the systems it supports and there are no opposite-unit SX System requirements.
If one unit-specific SX train is inoperable, action must be taken to restore OPERABLE status within 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br />.
In this Condition, the remaining OPERABLE SX train is adequate to perform the heat removal function.
However, the overall reliability is reduced because a single failure in the OPERABLE SX train could result in loss of the SX System function in the short term.
The 72 hour8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br /> Completion Time is based on the redundant capabilities afforded by the OPERABLE train, and the low probability of a DBA occurring during this time period.

The second Note indicates that the applicable Conditions and Required Actions of LCO 3.4.6, "RCS Loops-MODE 4," should be entered if an inoperable SX train results in an inoperable decay heat removal train.
These are exceptions to LCO 3.0.6 and ensure the proper actions are taken for these components.
Revision
BASES ACTIONS (continued)
BYRON - UNITS 1 & 2 B 3.7.8 - 5 SX System B 3.7.8 If the opposite-unit SX train is not OPERABLE for unit-specific support, action must be taken to restore OPERABLE status within 7 days.
In this Condition, if a complete loss of unit-specific SX were to occur, the SX System function would be lost.
The 7 day Completion Time is based on the capabilities of the unit-specific SX System and the low probability of a DBA with a loss of all unit-specific SX occurring during this time period.
Revision
BASES ACTIONS (continued)
SURVEILLANCE SR 3.7.8.1 REQUIREMENTS SX System B 3.7.8 If the unit-specific SX train or the opposite-unit SX train cannot be restored to OPERABLE status within the associated Completion Time, the unit must be placed in a MODE in which the LCO does not apply.
To achieve this status, the unit must be placed in at least MODE 3 within 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br /> and in MODE 5 within 36 hours4.166667e-4 days <br />0.01 hours <br />5.952381e-5 weeks <br />1.3698e-5 months <br />.
The allowed Completion Times are reasonable, based on operating experience, to reach the required unit conditions from full power conditions in an orderly manner and without challenging plant systems.
Verifying the correct alignment for manual, power operated, and automatic valves in the unit-specific SX flow path provides assurance that the proper flow paths exist for unit-specific SX operation.
This SR does not apply to valves that are locked, sealed, or otherwise secured in position, since they are verified to be in the correct position prior to being locked, sealed, or secured.
This SR does not require any testing or valve manipulation ;
rather, it involves verification that those valves capable of being mispositioned are in the correct position.
This SR does not apply to valves that cannot be inadvertently misaligned, such as check valves.
The 31 day Frequency is based on engineering judgment, is consistent with the procedural controls governing valve operation, and ensures correct valve positions.
This SR is modified by a Note indicating isolation of the SX components does not affect the OPERABILITY of the SX System.
Isolation of components may render those components inoperable.

<_ 0.95 (also on a 95/95 basis) for all postulated accident scenarios involving dropped or misloaded fuel assemblies Crediting the presence of soluble boron for mitigation of these scenarios is acceptable based on applying the "double contingency principle" which states that there is no requirement to assume two unlikely, independent, concurrent events to ensure protection against a criticality accident (Refs. 9 and 10).
The accident analyses address the following five postulated scenarios :
- 1) fuel assembly drop on top of rack ;

- 3) fuel assembly drop between rack modules and spent fuel pool wall ;

Spent Fuel Pool Boron Concentration B 3.7.15 Calculations were use performed, for the wee spent fuel pool storage racks, for a spent fuel pool temperature of 4°C (39°F) which is well below the lowest normal operating temperature (50°F).
Because the temperature coefficient of reactivity in the spent fuel pool is negative, temperatures greater than 4°C will result in a decrease in reactivity.
Calculations were also performed to show the largest reactivity increase caused by a Westinghouse 17X17 OFA fuel assembly misplaced into a lal-tee Region 2 storage cell for which the restrictions on enrichment or burnup are not satisfied.

A.1 and A.2 SURVEILLANCE SR 3.7.15.1 REQUIREMVTS Spent Fuel Pool Boron Concentration B 3.7.15 When the concentration of boron in the spent fuel pool is less than required, immediate action must be taken to preclude the occurrence of an accident or to mitigate the consequences of an accident in progress.
This is most efficiently achieved by immediately suspending the movement of fuel assemblies.
This does not preclude movement of a fuel assembly to a safe position.
Immediate actions are also taken to restore spent fuel pool boron concentration.
If moving fuel assemblies while in MODE 5 or 6, LCO 3.0.3 would not specify any action.
If moving fuel assemblies while in ES 1, 2, 3, and 4, the fuel movement is independent of reactor operations.
Therefore, inability to suspend movement of fuel assemblies is not sufficient reason to require a reactor shutdown.
This SR verifies that the concentration of boron in the spent fuel pool is within the required limit.
As long as this SR is met, the analyzed accidents are fully addressed.

Spent Fuel Assembly Storage B 3.7.16 The criticality analyses for the spent fuel assembly storage racks confirm that Kff remains
_< 0.95 for the Ho+tee spent fuel pool storage racks (including uncertainties and tolerances) at a 95% probability with a 95% confidence level (95/95 basis), based on the accident condition of the pool being flooded with unborated water.
Thus, the desi~n of both regions assumes the use of unborated water while maintaining stored fuel in a subcritical condition.
However, the presence of soluble boron has been credited to provide adequate safe mar~in to maintain spent fuel assembly storage rackIff
.95 (also on a 95/95 basis) for all postulated accident scenarios involving dropped or misloaded fuel assemblies Crediting the preseiCe of soluble boron for mitigation of these scenarios is acceptable based on applying the "double contingency principle" which states that there is no requirement to assume two unlikely, independent, concurrent events to ensure protection against a criticality accident (Refs. 9 and 10).
The accident analyses address the following five postulated scenarios :
- 1) fuel assembly drop on top of rack ;
- 2) fuel assembly drop between rack modules ;
- 3) fuel assembly drop between rack modules and spent fuel pool wall ;
4 change in spent fuel pool water temperature ; and 5~ fuel assembly loaded contrary to placement restrictions.
only scenarios 2, 3, and 5 have the `capacity to increase reactivity for the Herl-tee spent fuel pool storage racks.

BASES APPLICABLE SAFM ANALYSES (continued)
Spent Fuel Assembly Storage B 3.7.16 Calculations were also perfo for a spent fuel pool temperature of 4°C (39°F) which is well below the lowest normal operating temperature (50°F).
Because the temperature coefficient of reactivity in the spent fuel pool is negative, temperatures greater than 4°C will result in a decrease in reactivity.
For the fuel assembly misload accident, calculations were performed to show the largest reactivity increase caused by a Westinghouse 17X17 OFA fuel assembly misplaced into a leltee Region 2 storage cell for which the restrictions on enrichment or burnup are not satisfied.
The assembly misload accident can only occur during fuel handling operations in the spent fuel pool.

BASES APPLICABLE SAFETY ANALYSES (continued)
Spent Fuel Assembly Storage B 3.7.16 For the above postulated accident conditions, the double contingency principle can be lied.
Specifically, the presence of soluble boron in spent fuel pool water can assumed as a realistic initial condition since not assuming its presence would be a second unlikely event. FE spent fuel pool storage racks, sp~
t fuel pool soluble boron has been credited in the criticality safety analysis to offset the reactivity caused by postulated accident conditions.
Because theRegion 1 racks are designed for the storage of fresh fuel assemblies, a fuel assembly misload accident has no consequences from a criticality standpoint (i.e., the acceptance criteria for storage are satisfied by all assemblies in the spent fuel pool).

should a fuel assembly misload accident occur in the Region 2 storage cells, k, will be maintained <_ 0.95 due to the presence of at least 300 ppm of soluble boron in the spent fuel pool water.

use of linear interpolation between minimum burnups is acceptable.
When the configuration of fuel assemblies stored in the spent fuel pool is not in accordance with the requirements of the LCO, immediate action mast be taken to make the necessary fuel assembly movement(s) to bring the configuration into compliance.
If moving fuel assemblies while in MODE 5 or 6, WO 3.0.3 would not specify arty action.
If moving fuel assemblies while in MODES 1, 2, 3, and 4, the fuel movement is independent of reactor operations.
Therefore, inability to suspend movement of fuel assemblies is not sufficient reason to require a reactor shutdown.
