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 an amendment to Facility Operating License Nos. NPF-11 and NPF-18 for LaSalle County Station (LSCS) Units 1 and 2, respectively . The proposed amendment removes time, cycle, or modification-related items from the Operating Licenses (OLs) and Technical Specifications (TS). Additionally, the proposed amendment corrects a typographical error introduced into the TS in a previous amendment. The time, cycle, or modification-related items have been implemented or superseded, are no longer applicable, and no longer need to be maintained in their associated OLs or TS.

Specifically, the proposed amendment deletes obsolete License Conditions and removes conditional Notes related to TS associated with the Core Standby Cooling System (CSCS) valve replacement project. License Conditions proposed for deletion pertain to actions that have been completed and are no longer applicable . The refueling outages related to the extension of the Completion Times associated with the TS Sections 3.7.1, "Residual Heat Removal Service Water (RHRSW) System," 3 .7.2, "Diesel Generator Cooling Water (DGCW) System," and 3.8.1, "AC Sources - Operating," are complete and the added Conditions are no longer needed .

Additionally, there is an administrative typographical correction to Reference 1 in TS Section 5 .6.5, "Core Operating Limits Report (COLR)."

This exemption was approved by the NRC in SSER #2 (NUREG-0519) "Safety Evaluation Report related to the operation of LaSalle County Station, Units 1 and 2, Supplement No. 2," page 22-1 dated February 1982 (Reference 38) . The exemption required that all participants perform a small-scale exercise again within the months prior to issuance of the full power OL. Because this was a one-time exemption, this condition is considered closed .

Delete Unit 1 OLC 2.D(d), which allowed a one-time exemption from 10 CFR 50.44 until either the required 100 percent rated thermal power trip startup test was completed or the reactor operated for 120 effective full power days. The exemption was approved by the NRC in letter from Darrell G . Eisenhut (NRC) to Louis L. DelGeorge (Licensee), "Amendment No. 12 to OL No. NPF LaSalle County Station, Unit 1," dated December 20, 1982 (Reference 39). This was a one-time only exemption and is therefore obsolete and should be deleted .

Delete Unit 1 OL Attachment 1 in its entirety . Attachment 1 identified certain preoperational tests, system demonstrations and other items that were required to be completed to the satisfaction of the NRC prior to proceeding to Mode 2 (i.e., initial criticality of 212°F) . LSCS was not permitted to proceed beyond this Operational Mode without written confirmation from the NRC that the items contained in Attachment 1 were completed. In a letter from the NRC to Commonwealth Edison dated June 19, 1982 (Reference 40), the NRC confirmed that they have reviewed items identified in Attachment 1 to FOL NPF-11 and determined that they were completed in accordance with the conditions . Reference 39 also allowed LSCS Unit 1 to proceed with reactor operations in Mode 2 to initial criticality and zero power physics testing .

Further confirmation of the completion of all preoperational tests, startup tests, and other items identified in Attachment 1 to NPF-11 is documented in the July 1982 issuance of the Safety Evaluation Report for LSCS Units 1 and 2 (Reference 18) and therefore Attachment 1 to NPF-11 is obsolete and should be deleted.

3.0 BACKGROUND

Historically, conditions, exceptions, or exemptions that are date, cycle, or modification-related have been captured in the OL. Over time, the actions or requirements that these items contain are implemented, and the issues no longer need to be reflected in the OL. In an effort to clarify, and avoid any confusion regarding the current requirements contained in the OL, EGC is proposing the administrative removal of these items from the OL and TS for LaSalle County Station.

4.0 TECHNICAL EVALUATION

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

Page 1 2 of 18

ATTACHMENT 1 Evaluation of Proposed Changes

5.0 REGULATORY EVALUATION

5.1 No Significant Hazards Consideration In accordance with 10 CFR 50 .90, " Application for amendment of license, construction permit, or early site permit," Exelon Generation Company, LLC (EGC) is requesting an amendment to Operating License (OL) Nos. NPF-11 and NPF-18 for LaSalle County Station. The proposed amendment provides 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.

According to 10 CFR 50.92, "Issuance of amendment," paragraph (c), a proposed amendment to an OL 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 .

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.

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?

Page 1 3 of 18

ATTACHMENT I Evaluation of Proposed Changes 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 .

3. Does the proposed amendment involve a significant reduction in a margin of safety?

Response : No 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 OLCs have been satisfied as required .

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.

5.3 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 Page 1 4 of 18

ATTACHMENT 1 Evaluation of Proposed Changes 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),

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.

Required Action A .1 is intended to handle the inoperability of one RHRSW subsystem . The Completion Time of 7 days is allowed to restore the RHRSW subsystem to OPERABLE status .

With the unit in this condition, the remaining OPERABLE RHRSW subsystem is adequate to perform the RHRSW heat removal function . However, the overall reliability is reduced because a single failure in the OPERABLE RHRSW subsystem could result in loss of RHRSW function . The Completion Time is based on the redundant RHRSW capabilities afforded by the OPERABLE subsystem and the low probability of an event occurring requiring RHRSW during this period .

The Required Action is modified by a Note indicating that the applicable Conditions of LCO 3 .4 .9, be entered and Required Actions taken if the inoperable RHRSW subsystem results in inoperable RHR shutdown cooling . This is an exception to LCO 3 .0 .6 and ensures the proper actions are taken for these components .

If one RHRSW subsystem is inoperable and not restored within the provided Completion Time, the plant must be brought to a condition in which the overall plant risk is minimized . To achieve this status, the plant must be brought to at least MODE 3 within 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> . Remaining in the Applicability of the LCO is acceptable because the plant risk in MODE 3 is similar to or lower than the risk in MODE 4 (Ref . 6) and because the time spent in MODE 3 to perform the necessary repairs to restore the system to OPERABLE status will be short . However, voluntary entry into MODE 4 may be made as it is also an acceptable low-risk state . The allowed Completion Time is reasonable, based on operating experience, to reach the required plant conditions from full power conditions in an orderly manner and without challenging plant systems .

With both RHRSW subsystems inoperable (e .g ., both subsystems with inoperable pump(s) or flow paths, or one subsystem with an inoperable pump and one subsystem with an inoperable flow path), the RHRSW System is not capable of performing its intended function . At least one subsystem must be restored to OPERABLE status within 8 hours9.259259e-5 days <br />0.00222 hours <br />1.322751e-5 weeks <br />3.044e-6 months <br /> .

This SR does not apply to valves that are locked, sealed, or otherwise secured in position, since these valves are verified to be in the correct position prior to locking, sealing, or securing . A valve is also allowed to be in the nonaccident position, and yet considered in the correct position, provided it can be realigned to its accident position . This is acceptable because the RHRSW System is a manually initiated system .

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 .

If one or more DGCW subsystems are inoperable, the associated DG(s) and ECCS components supported by the affected DGCW loop, including LPCS pump motor cooling coils or ECCS cubicle area cooling coils, as applicable, cannot perform their intended function and must be immediately declared inoperable . In accordance with LCO 3 .0 .6, this also requires entering into the Applicable Conditions and Required Actions for LCO 3 .4 .9, "RHR Shutdown Cooling System

This SR does not apply to valves that are locked, sealed, or otherwise secured in position since these valves were verified to be in the correct position prior to locking, sealing, or securing . A valve is also allowed to be in the nonaccident position, and yet be considered in the correct position provided it can be automatically realigned to its accident position, within the required time . 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 .

SR_ 3 .7 .2 .2 This SR ensures that each DGCW subsystem pump will automatically start to provide required cooling to the associated DG, LPCS pump motor cooling coils, and ECCS cubicle area cooling coils, as applicable, when the associated DG starts and the respective bus is energized .

For the Division 1 DGCW subsystem, this SR also ensures the DGCW pump automatically starts on receipt of a start signal for the unit LPCS pump . These starts may be performed using actual or simulated initiation signals .

Operating experience has shown that these components usually pass the SR when performed at the 24 month Frequency, which is based at the refueling cycle . Therefore, this Frequency is concluded to be acceptable from a reliability standpoint .

AC Sources-Operating B 3 .8 .1 BASES ACTIONS B .4 (continued)

The "AND" connector between the 14 day and 17 day Completion Times means that both Completion Times apply simultaneously, and the more restrictive Completion Time must be met .

Similar to Required Action B .2, the Completion Time of Required Action B .4 allows for an exception to the normal "time zero" for beginning the allowed outage time "clock ."

This exception results in establishing the "time zero" at the time the LCO was initially not met, instead of the time Condition B was entered .

Condition C on C is modified by two Notes indicatin this Condition i applicable during re ent of Division 2 CSCS isolation valve cified unit outages while the outage un n or defueled . When the Divisio s are inoperable during CS isolation val ntenance, Condition G provides appropri fired ctions .

To ensure a highly reliable power source remains, it is necessary to verify the availability of the remaining required offsite circuit on a more frequent basis . Since the Required Action only specifies "perform," a failure of SR 3 .8 .1 .1 acceptance criteria does not result in a Required Action being not met . However, if a circuit fails to pass SR 3 .8 .1 .1, it is inoperable . Upon offsite circuit inoperability, additional Conditions must then be entered .

Required Action C .2 is intended to provide assurance that a loss of offsite power, during the period that the DG(s) is inoperable as described in Condition C, does not result in a complete loss of safety function of critical systems . These features are designed with redundant safety related divisions (i .e ., single division systems are not included, although, for this Required Action, Division 3 (HPCS System) is considered redundant to Division 1 and 2 ECCS) .

LaSalle 1 and 2 B 3 .8 .1-13 Revision 28

AC Sources-Operating B 3 .8 . 1 BASES ACTIONS E .1 and E .2 (continued)

According to Regulatory Guide 1 .93 (Ref . 6), operation may continue in Condition E for a period that should not exceed 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> . In Condition E, individual redundancy is lost in both the offsite electrical power system and the onsite AC electrical power system . Since power system redundancy is provided by two diverse sources of power, however, the reliability of the power systems in this Condition may appear higher than that in Condition D (loss of both required offsite circuits) . This difference in reliability is offset by the susceptibility of this power system configuration to a single bus or switching failure . The 12 hour1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> Completion Time takes into account the capacity and capability of the remaining AC sources, reasonable time for repairs, and low probability of a DBA occurring during this period .

Condition F on F is modified by two Notes indic that this Condition i applicable Burin acement of Division 2 CSCS isolation valve specified unit outages while the outage un i 5, or defueled . When the Divisio s are inoperable duri CSCS isolation val ntenance, Condition G provides appropr equired ctions .

With two required unit DGs inoperable or both required Division 2 DGs inoperable, there is no more than two remaining standby AC sources . Thus, with an assumed loss of offsite electrical power, sufficient standby AC sources may not be available to power the minimum required ESF functions . Since the offsite electrical power system is the only source of AC power for the majority of ESF equipment at this level of degradation, the risk associated with continued operation for a very short time could be less than that associated with an immediate controlled shutdown (the immediate shutdown could cause grid instability, which could result in a total loss of AC power) . Since any inadvertent generator trip could also result in a total loss of offsite AC power, however, the time allowed for continued operation (continued)

Thus, with an assumed to of offsite el trical power, sufficient standby AC sources not be av lable to power the minimum required Division 2 ES functi s. Since the offsite electrical power system t e only source of AC power for the Division 2 ESF equipm at this level of degradation, the risk associated wit con nued operation during the Division 2 CSCS valve eplacem t maintenance must be mitigated by the of mechanic 1 line stops to maintain the availability the Division 'CSCS system for the online Unit . T line stops are de gned to the same pressure rati 9 and seismic design as he CSCS piping . At least one r quired Division 2 OG must b restored to OPERABLE tatus within 6 days of entry in Condition G .

This C pletion Time is based upon a risk-i rmed ass ment that concluded that the associate isk with the n in the specified configuration is acceptab e (Ref . 13) .

at least one Division 2 DG is not maintained ailable while in this Condition, the assumptions of the s assessment of Reference 13 are no longer valid and Condition H should be entered immediately .

If the inoperable AC electrical power sources cannot be restored to OPERABLE status within the associated Completion Time, the unit must be brought to a MODE in which the overall plant risk is minimized . To achieve this status, the unit must be brought to MODE 3 within 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> .

Remaining in the Applicability of the LCO is acceptable because the plant risk in MODE 3 is similar to or lower than the risk in MODE 4 (Ref . 14) and because the time spent in MODE 3 to perform the necessary repairs to restore the system to OPERABLE status will be short .

However, voluntary entry into MODE 4 may be made as it is also an acceptable low-risk state . The allowed Completion Time is reasonable, based on operating experience, to (continued)

AC Sources-Operating B 3 .8 . 1 BASES ACTIONS (continued) reach the required plant conditions from full power conditions in an orderly manner and without challenging plant systems, of degradation in which lectrical power supplies has been verely degra _evel, any further losses electrical power system wi se a loss of function . Therefore, no additional time is j ied for continued operation . The unit is required by LCO 3 commence a controlled shutdown .

SURVEILLANCE The AC sources are designed to permit inspection and REQUIREMENTS testing of all important areas and features, especially those that have a standby function, in accordance with 10 CFR 50, GOC 18 (Ref . 8) . Periodic component tests are supplemented by extensive functional tests during refueling outages under simulated accident conditions . The SRs for demonstrating the OPERABILITY of the DGs are consistent with the recommendations of Regulatory Guide 1 .9 (Ref . 3) and Regulatory Guide 1 .137 (Ref . 9) .

The Surveillances are modified by two Notes to clearly identify how the Surveillances apply to the given unit and opposite unit's Division 2 DGs . Note 1 states that SR 3 .8 .1 .1 through SR 3 .8 .1 .20 are applicable only to the given unit AC electrical power sources and Note 2 states that SR 3 .8 .1 .21 is applicable to the opposite unit's Division 2 DG . These Notes are necessary since the opposite unit AC electrical power source is not required to meet all of the requirements of the given unit AC electrical power sources (e .g ., the opposite unit DG is not required to start on the opposite unit's ECCS initiation signal to support OPERABILITY of the given unit) .

Where the SRs discussed herein specify voltage and frequency tolerances, the following summary is applicable . The minimum steady state output voltage of 4010 V is greater than 90% of the nominal 4160 V output voltage . This value, which is conservative with respect to the value specified in ANSI C84 .1 (Ref . 10), allows for voltage drop to the terminals of 4000 V motors whose minimum operating voltage is specified as 90%, or 3600 V . It also allows for voltage (continued)
