ATTACHMENT 1 Evaluation of Proposed Changes License Amendment Request to Delete Obsolete License Conditions and Revise Technical Specifications 1.0     

==SUMMARY==
DESCRIPTION In accordance with 10 CFR 50.90, "Application for amendment of license, construction permit, or early site permit," Exelon Generation Company, LLC (EGC) requests amendments to Renewed Facility Operating License Nos. NPF-72 and NPF-77 for Braidwood Station, Units 1 and 2, and Renewed Facility Operating License Nos. NPF-37 and NPF-66 for Byron Station, Units 1 and 2. The proposed amendment removes time, cycle, or modification-related items from the Operating Licenses (OLs) and Technical Specifications (TS). The time, cycle, or modification-related items have been implemented or superseded, are no longer applicable, and no longer need to be maintained in their associated OLs or TS. Additionally, the proposed amendment makes editorial and formatting changes.
Specifically, the proposed amendment deletes obsolete License Conditions related to first performances of associated Control Room Envelope (CRE) habitability surveillance, assessment and measurement tests for both Braidwood Station and Byron Station. The other License Condition proposed for deletion includes removal of TS associated with AREVA NP Inc.
(AREVA NP) fuel for Braidwood Station, Unit 1 only. The License Conditions proposed for deletion pertain to actions or dates that have been completed and are no longer applicable.
Further, the proposed amendment deletes text tied to completed refueling outages, system outages, or operating cycles and are no longer needed.
2.0     DETAILED DESCRIPTION 2.1     Reason for the Proposed Changes The proposed changes are meant to remove time, cycle, or modification-related items from the OLs and TS. These items have been implemented or superseded, are no longer applicable, and no longer need to be maintained in their associated OLs or TS. With each proposed change, other than changes editorial in nature, associated evidence is identified to support the implementation as appropriate.
Historically, conditions, exceptions, or exemptions that are date, cycle, or modification-related have been captured in the OLs or TS. Over time, the actions or requirements that these items prescribe are implemented, and the issues no longer need to be reflected in the OLs or TS. In an effort to clarify, and avoid any confusion regarding the current requirements contained in the OL or TS, EGC is proposing the administrative removal of these items from the OLs and the TS for Braidwood Station and Byron Station.
In addition, a review was performed to identify inconsistencies in format within the Braidwood Station and Byron Station TS. The review utilized the improved Standard Technical Specifications (STS), Revision 1 (Reference 1) and the Writer's Guide for Plant-Specific Improved Technical Specifications (WG), TSTF-GG-05-01 (Reference 2). STS Revision 1 is the basis for TS format for Braidwood Station and Byron Station. The WG utilized for the review incorporates updates since STS Revision 1, but also describes the STS Revision 1 format. The existing format, using STS Revision 1, will not be changed. The results of these reviews were used as input for the proposed editorial and formatting changes. A complete listing of all proposed changes is provided in Table 2-1.

==3.0      TECHNICAL EVALUATION==

All proposed changes are administrative in nature and require no technical analysis.

==4.0      REGULATORY EVALUATION==

4.1      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.
4.2     No Significant Hazards Determination In accordance with 10 CFR 50.90, "Application for amendment of license, construction permit, or early site permit," EGC is requesting amendments to OL Nos. NPF-72 and NPF-77 for Braidwood Station, Units 1 and 2, and OL Nos. NPF-37 and NPF-66 for Byron Station, Units 1 Page 7 of 9

ATTACHMENT 1 Evaluation of Proposed Changes License Amendment Request to Delete Obsolete License Conditions and Revise Technical Specifications and 2. The proposed amendments provide for the administrative removal of time, cycle, or modification-related items from the OLs 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 OL. Additionally, the proposed amendment makes editorial and formatting changes.
EGC has evaluated whether or not a significant hazards consideration is involved with the proposed amendment(s) by focusing on the three standards set forth in 10 CFR 50.92, "Issuance of amendment," as discussed below:
: 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, items that are no longer applicable, or are editorial. 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.
Therefore, 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 previously evaluated?
Response: No None of the proposed changes affect the design or operation of any system, structure, or component in the plants. 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.
Therefore, the proposed changes do not create the possibility of a new or different kind of accident from any previously evaluated.

ATTACHMENT 1 Evaluation of Proposed Changes License Amendment Request to Delete Obsolete License Conditions and Revise Technical Specifications
: 3. Does the proposed amendment involve a significant reduction in a margin of safety?
Response: No The proposed changes 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 OL Conditions have been satisfied as required.
Therefore, the proposed changes do not involve a significant reduction in a margin of safety.
Based on the above, EGC concludes that the proposed changes do not involve a significant hazards consideration as set forth in 10 CFR 50.92(c), "Issuance of Amendment."
4.3 Conclusions 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.

==5.0     ENVIRONMENTAL CONSIDERATION==

The proposed amendment meets the eligibility criterion for categorical exclusion set forth in 10 CFR 51.22(c)(9). 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 effluents that may be released offsite, or (iii) a significant increase in individual or cumulative occupational radiation exposure. Therefore, pursuant to 10 CFR 51.22(b), no environmental impact statement or environmental assessment need be prepared in connection with the proposed amendment.

SX System B 3.7.8 B 3.7 PLANT SYSTEMS B 3.7.8 Essential Service Water, (SX) System BASES BACKGROUND        The SX System provides a heat sink for the removal of process and operating heat from safety related components during a Design Basis Accident (DBA) or transient. During normal operation, and a normal shutdown, the SX System also provides this function for various safety related and nonsafety related components. The safety related function is covered by this LCO.
The unit-specific SX System consists of two separate, electrically independent, 100% capacity, safety related, cooling water trains. Each train consists of a 100%
capacity pump, piping, valving, and instrumentation. The pumps and valves are remote and manually aligned, except in the unlikely event of a Loss Of Coolant Accident (LOCA).
The pumps are automatically started upon receipt of a safety injection signal or an undervoltage on the ESF bus, and all essential valves are aligned to their post accident positions (Diesel Generator (DG) supply valves are opened once the DG has reached sufficient rpm). The SX System is the backup water supply to the Auxiliary Feedwater System.
The SX System includes provisions to crosstie the trains (unit-specific crosstie), as well as provisions to crosstie the units (opposite-unit crosstie). The opposite-unit crosstie valves (1SX005 and 2SX005) must both be open to accomplish the opposite-unit crosstie. The system is normally aligned with the unit-specific crosstie valves open and the opposite-unit crosstie valves closed.
Additional information about the design and operation of the SX System, along with a list of the components served, is presented in the UFSAR, Section 9.2.1 (Ref. 1). Some of the functions served by the SX System are the removal of decay heat from the reactor via the Component Cooling Water (CC)
System, the removal of heat from containment via the reactor containment fan coolers, and cooling of the DGs.
BRAIDWOOD EH9                     B 3.7.8  1                        Revision SX System B 3.7.8 BASIS APPLICABLE         The design basis of the SX System is for one SX train, in SAFETY ANALYSES    conjunction with the CC System and a 100% capacity containment cooling system, to remove core decay heat following a design basis LOCA as discussed in the UFSAR, Section 6.2 (Ref. 2). This prevents the containment sump fluid From increasing in temperature during the recirculation phase following a LOCA and provides for a gradual reduction in the temperature of this fluid as it is supplied "to the Reactor Coolant System by the Emergency Core Cooling System pumps. The SX System is designed to perform its function with a single failure of any active component, assuming the loss of offsite power.
The SX System, in conjunction with the CC System, also cools the unit from Residual Heat Removal (RHR) entry conditions, as discussed in the UFSAR, Section 5.4.7, (Ref. 3) to MODE 5 during normal and post accident operations. The time required for this evolution is a function of the number of CC and RHR System trains that are operating. One SX train is sufficient to remove decay heat during subsequent operations in MODES 5 and 6.
Generic Letter 91-13 (Ref. 4) included risk-based recommendations for enhancing the availability of SX Systems, in the case of a loss of all SX to a particular unit. Crediting the opposite-unit SX System with an opposite-unit pump and the opposite-unit crosstie valves, was a part of the response to this Generic Letter.
The unit-specific SX System satisfies Criterion 3 of 10 CFR 50.36(c)(2)(ii). The opposite-unit SX System satisfies Criterion 4 of 10 CFR 50.36(c)(2)(ii).

A unit-specific SX train is considered OPERABLE during MODES 1, 2, 3, and 4 when:
: a. The pump is OPERABLE; and
: b. The associated piping, valves, and instrumentation and controls required to perform the safety related function are OPERABLE.
An opposite-unit SX train is considered OPERABLE during MODES 1, 2, 3, and 4 when:
: a. An opposite-unit pump is capable of performing its required unit-sp ?cific function (manually start and supply SX to the flow path);
: b. A flow path from the opposite unit is established, or capable of being established (including the opposite-unit cri Dsstie valves 1SX005 and 2SX005); and C. The associated piping, valves, and instrumentation and controls are capable of performing the crosstie function.

SX System B 3.7.8 13ASI-S 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.
While a specific unit is in MODES 1, 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.
ACTIONS            A.1 If one unit-specific SX train is inoperable, action must be taken to restore OPERABLE status within 72 hours. 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 hour 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.
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.

SX System B 3. 7.8 3ASI S ACIIONS (continued)
B.I 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.
C.1 and C.2 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 hours and in MODE 5 within 36 hours.
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.

SX System B 3. 1.8 BASES SURVEILLANCE     SR 3.7.8.1 REQUIREMENTS 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 Surveillance Frequency is controlled under the Surveillance Frequency Control Program.
This SR is modified by a Note indicating isolation of the 9 components does not affect the OPERABILITY of the SX System.
Isolation of components may render those components inoperable.
SR 3.7.8.2 This SR verifies that the opposite-unit SX pump can be run for >_ 15 minutes. This SR does not require the opposite-unit pump to supply SX to the specific unit.
SR 3.7.8.2 is modified by a note that only requires this surveillance to be performed when the opposite unit is in MODE 5 or 6 or has no fuel in the reactor vessel. If the opposite unit is in MODE 1, 2, 3, or 4, its SX System is normally operating. If the opposite unit is shut down, the credited SX pump may not be operating. Therefore, the Note requires the surveillance to be performed. The Surveillance Frequency is controlled under the Surveillance Frequency Control Program.

The SX System is a normally operating system that cannot be fully actuated as part of normal testing. This Surveillance is not required for valves that are locked, sealed, or otherwise secured in the required position under administrative controls. The Surveillance Frequency is controlled under the Surveillance Frequency Control Program.

ATTACHMENT Proposed Technical Specification Bases Changes for Byron Station, Units 1 and 2

SX System B 3. 7.8 BASES ACTIONS           A.I If one unit-specific SX -train is inoperable, action must be taken to restore OPERABLE status within 72 hours. 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 hour 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.

SX System B 3.7.8 BASES ACTIONS (conL i rued)
                      .G __1.
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 hours and in MODE 5 within 36 hours.
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.
SURVEILLANCE        SR 3.7.8.1 REQUIREMENTS 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 Surveillance Frequency is controlled under the Surveillance Frequency Control Program.
