: 1. DESCRIPTION The purpose of this change is to modify the definition of OPERABLE to conform to the Improved Technical Specifications (NUREG-1431, Rev. 3, "Standard Technical Specifications for Westinghouse Plants.") and incorporate appropriate conditions into electrical power systems limiting Conditions for Operation (LCOs) for AC & DC Sources and Distribution during Modes 5 & 6 and during movement of irradiated fuel assemblies.
: 2. PROPOSED CHANGE PSEG is requesting that the definition of OPERABLE be changed to conform to the definition in Improved Technical Specifications (ITS) allowing equipment to be considered OPERABLE with either normal or emergency electrical power available. Changes to the Technical Specifications (TS) for electrical power systems for AC & DC Sources and Distribution during Modes 5 & 6 and during movement of irradiated fuel assemblies are also revised to conform to ITS.
These changes extend the relief granted by Amendments 253/234 to the shutdown modes and allow declaring supported systems inoperable rather than always suspending core alterations.
The above changes are shown on the attached proposed changed pages (Attachment 2). Changes to be inserted in the bases for Electrical Power Systems are also included in attachment 2.
: 3. BACKGROUND On November 1, 2001, PSEG Nuclear LLC submitted License Change Request (LCR) S01-02 (LR-N01-0200) to incorporate ITS provisions regarding operability of normal and emergency power during Modes 1 - 4. LCR S01-02 was supplemented by letter dated October 1,2002 (LR-N02-0332). LCR S01 -02 was approved by License Amendments 253 and 234 for Unit 1 and Unit 2, respectively. The above amendments did not change the definition of OPERABLE and did not address modes 5 and 6. The changes proposed by this request extend flexibility to cover Modes 5 & 6 and revise the definition of OPERABLE to coordinate with the LCOs of TS section 3/4 3.8. The proposed changes are intended to provide outage scheduling flexibility and avoid unnecessary disruption of refueling activities while still providing for appropriate actions to assure nuclear safety.

: 4. TECHNICAL ANALYSIS The proposed change's improve clarity of the TS and remove potential conflicting requirements. The current TS can be interpreted to require equipment supported by an inoperable AC source to also be declared inoperable, since the definition of OPERABLE in the Salem Unit 1 & 2 TS specifies that both "normal and emergency power" are needed. However, TS 3.8.1.1 allows operation to continue up to 24 hours for an A.C. circuit, 12 hours for 2 inoperable A.C. circuits, or 4 hours for a diesel generator before equipment supported by an inoperable AC source needs to be declared inoperable, if the redundant supported equipment is inoperable. Specification 3.8.1.1 is intended to allow operation to be governed by the time limits of the action statement associated with the Limiting Condition for Operation (LCO) of the normal or emergency power source, rather than the corresponding action statement for each affected system or component. The proposed changes to the definition of OPERABLE are consistent with ITS and specifies that either "normal or emergency power" are needed. The proposed change to the definition of OPERABLE removes any potential confusion.
The LCOs for AC & DC Sources and Distribution during Modes 5 &6 and during movement of irradiated fuel assemblies are also modified to be consistent with the intent of ITS. (Note: The ITS LCO for distribution while shutdown is 3.8.10 while equivalent Salem LCOs are 3.8.2.2, 3.8.2.4, and 3.8.2.6. Also ITS LCO 3.8.5 for D.C. sources shutdown is covered by Salem LCOs 3.8.2.4 and 3.8.2.6.
In addition, ITS LCO 3.8.8 for Inverters shutdown is covered by Salem LCO 3.8.2.2.) The current TS requires suspending core alterations when any A.C. or D.C. source is lost in Modes 5 & 6 or during movement of irradiated fuel. The proposed changes provide an option to take action in accordance with the LCO for the affected required features when a required power source (A.C. or D.C.) or distribution system (A.C. or D.C.) is lost or to take action to suspend all operations involving CORE ALTERATIONS or positive reactivity changes until the minimum required power sources or distribution system are restored to OPERABLE status. This flexibility is reasonable since not all power source or distribution system inoperabilities affect equipment required for CORE ALTERATIONS or positive reactivity changes. The LCOs for the affected required features contain requirements to address the condition and to discontinue CORE ALTERATIONS or positive reactivity changes when it is appropriate. Therefore, the proposed changes continue to assure that the plant is placed in a safe condition but avoid overly restrictive actions.
In general, when the unit is shut down, the Technical Specifications requirements ensure that the unit has the capability to mitigate the consequences of postulated accidents. However, assuming a single failure and concurrent loss of all offsite or all onsite power is not required. This allowance allows performance of a significant number of required testing and maintenance activities to be conducted provided an acceptable level of risk is not exceeded.

Document Control Desk                                                         LR-N04-0238 Attachment I                                                                   LCR S04-06 Relaxations from MODE 1, 2, 3, and 4 LCO requirements during shutdown modes are justified because, activities are planned and administratively controlled, outage time is limited, and the risk associated with multiple activities that could affect multiple systems is controlled.
The TS ensure that all required loads are powered from offsite power with EDG backup ensures a diverse power source is available to provide electrical power support, assuming a loss of the offsite circuit. Together, OPERABILITY of the required offsite circuit and EDG ensures the availability of sufficient AC sources to operate the unit in a safe manner and to mitigate the consequences of postulated events during shutdown.
: 5. REGULATORY SAFETY ANALYSIS 5.1    No Significant Hazards Consideration PSEG Nuclear LLC (PSEG) has evaluated whether or not a significant hazards consideration is involved with the proposed changes by focusing on the three standards set forth in 10 CFR 50.92, "Issuance of amendment" as discussed below:
: 1. Does the proposed change involve'a significant increase in the probability or consequences of an accident previously evaluated?
Response:      No.
The likelihood of an event is not increased since the proposed changes do not alter the number or types of equipment required to be OPERABLE.
Also, the probability of occurrence or the consequences for an accident is not increased by the proposed changes since the minimum configuration of equipment required by individual TS will remain available. Further, the proposed changes do not alter the way any structure, system or component (SSC) functions, do not modify the manner in which the plant is operated, and do not significantly alter equipment out-of-service time.
No changes to the design of structures, systems, or components (SSC) are made and there are no effects on accident mitigation.
Therefore, the proposed changes do not involve a significant increase in the probability or consequences of an accident previously evaluated.
: 2. Does the proposed change create the possibility of a new or different kind of accident from any accident previously evaluated?
Response:      No.

Document Control Desk                                                              LR-N04-0238                                                                         LCR S04-06 The possibility of a new or different kind of accident from any accident or malfunction in the Salem Updated Final Safety Analysis Report (UFSAR) is not created. The allowable outage time is consistent with requirements of Improved Standard Technical Specifications and does not introduce any new or different failure from any previously evaluated or change the manner in which safety systems are operated. The associated system and equipment configurations are no different from those previously evaluated. Therefore a different accident is not created. In addition, the proposed changes cannot initiate an accident. Further, the proposed changes do not change the design function or operation of any SSCs.
Therefore, the proposed changes do not create the possibility of a new or different kind of accident from any previously evaluated.
: 3.      Does the proposed change involve a significant reduction in a margin of safety?
Response:       No.
The proposed changes continue to provide assurance that an event coincident with failure of an associated diesel generator or offsite power circuit will not result in complete loss of safety function of critical required redundant systems or equipment. In addition, the proposed changes do not change the margin of safety since no SSCs are changed. The results of accident analysis remain unchanged by the proposed.
Therefore, the proposed changes do not involve a significant reduction in a margin of safety.
Based on the above, PSEG concludes that the proposed changes present no significant hazards consideration under the standards set forth in 10 CFR 50.92(c), and accordingly, a finding of "no significant hazards consideration" is justified.
5.2     Applicable Regulatory Requirements/Criteria General Design Criterion (GDC) 17 of Appendix A to 10 CFR 50 "Electric power systems" applies to this change. The objectives of GDC 17 to provide reliable and diverse electrical power to address plant events continue to be met with the proposed changes. There are no changes to the design of the plant, therefore, the method of compliance with GDC 17 remains unchanged. In addition, the TS ensure that all required loads are powered from offsite power with EDG backup to ensure a diverse power source is available to provide electrical power support, assuming a loss of the offsite circuit. Together, OPERABILITY of the required offsite circuit and EDG ensures the availability of sufficient AC sources to operate 4

Document Control Desk                                                           LR-N04-0238 Attachment I                                                                     LCR S04-06 the unit in a safe manner and to mitigate the consequences of postulated events during shutdown.
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. ENVIRONMENTAL CONSIDERATION PSEG has determined the proposed amendment relates to changes in a requirement with respect to installation or use of a facility component located within the restricted area, as defined in 10 CFR 20, or relates to changes in an inspection or a surveillance requirement. 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. Accordingly, the proposed amendment meets the eligibility criteria for categorical exclusion set forth in 10 CFR 51.22(c)(9). Therefore, pursuant to 10 CFR 51.22(b), an environmental assessment of the proposed change is not required.

Insert for Bases 3/4.8 ELECTRICAL POWER SYSTEMS page 3/4 8-2 An offsite circuit would be considered inoperable if it were not available to one required train. Although two trains are required by LCOs are 3.8.2.2, 3.8.2.4, and 3.8.2.6, the one train with offsite power available may be capable of supporting sufficient required features to allow continuation of CORE ALTERATIONS and irradiated fuel movement. By the allowance of the option to declare required features inoperable, with no offsite power available, appropriate restrictions will be implemented in accordance with the affected required features LCO's actions.
With the offsite circuit not available to all required trains, the option exists to declare all required features inoperable. Since this option may involve undesired administrative efforts, the allowance for sufficiently conservative actions is made. With a DG inoperable, the minimum required diversity of AC power sources may not be available. Therefore, it may be required to suspend CORE ALTERATIONS, movement of irradiated fuel assemblies, and operations involving positive reactivity additions that could result in loss of required shutdown margin or boron concentration. Suspending positive reactivity additions that could result in failure to meet the minimum shutdown margin or boron concentration limit is required to assure continued safe operation.

3/4.8 ELECTRICAL POWER SYSTEMS BASES (Continued) or components that are associated with the other train that has power, results in starting the completion times for the Action. The specified time is acceptable because it minimizes risk while allowing time for restoration before subjecting the unit to transients associated with shutdown.
The remaining OPERABLE AC supplies (one offsite circuit and three DGs for Condition (a), two offsite circuits and two DGs for Condition (b), or three DGs for Condition (d)) are adequate to supply electrical power to the onsite Class lE Distribution System. Thus, on a component basis, single failure protection for the required system or component's function may have been lost; however, function has not been lost. The completion time takes into account the component OPERABILITY of the redundant counterpart to the inoperable required system or component. Additionally, the completion time takes into account the capacity and capability of the remaining AC sources, a reasonable time for repairs, and the low probability of a DBA occurring during this period. The completion time for Condition d (loss of both offsite circuits) is reduced to 12 hours from that allowed for one train without offsite power (Action 3.8.1.1.a.2). The rationale is that Regulatory Guide 1.93 allows a completion time of 24 hours for two required offsite circuits inoperable, based upon the assumption that two complete safety trains are OPERABLE. When a concurrent redundant required system or component failure exists, this assumption is not the case, and a shorter completion time of 12 hours is appropriate.
The OPERABILITY of the minimum specified A.C. and D.C. power sources and associated distribution systems during shutdown and refueling ensures that
: 1) the facility can be maintained in the shutdown or refueling condition for extended time periods and 2) sufficient instrumentation and control capability is available for monitoring and maintaining the unit status.
The Applicability of specifications 3.8.2.2, 3.8.2.4, and 3.8.2.6 includes the movement of irradiated fuel assemblies. This will insure adequate electrical power is available for proper operation of the fuel handling building ventilation system du      movement of irradiated fuel in the spent fuel pool.
The Surveillance Requirements for demonstrating the OPERABILITY of the diesel generators are based upon the recommendations of Regulatory Guide 1.9, "Selection of Diesel Generator Set Capacity for Standby Power Supplies,"
March 10, 1971, and Regulatory Guide 1.108, "Periodic Testing of Diesel Generator Units Used as Onsite Electric Power Systems at Nuclear Power Plants," Revision 1, August 1977. Regulatory Guide 1.108 criteria for determining and reporting valid tests and failures, and accelerated diesel generator testing, have been superseded by implementation of the Maintenance Rule for the diesel generators per 10CFR50.65. In addition to the Surveillance Requirements of 4.8.1.1.2, diesel preventative maintenance is performed in accordance with procedures based on manufacturer's recommendations with consideration given to operating experience.
The minimum voltage and frequency stated in the Surveillance Requirements (SR) are those necessary to ensure the Emergency Diesel Generator (EDG) can accept Design Basis Accident (DBA) loading while maintaining acceptable voltage and frequency levels. Stable operation at the nominal voltage and frequency values is also essential in establishing EDG OPERATILITY, but a time constraint is not imposed. The lack of a time constraint is based on the fact that a typical EDG will experience a period of voltage and frequency oscillations prior to reaching steady state operation if these oscillations are not dampened out by load application.

If at any time during these conditions a redundant required system or component subsequently becomes inoperable, this completion time begins to be tracked. Discovering no offsite power to one train of the onsite Class lE Electrical Power Distribution System, or one required DG inoperable, coincident with one or more inoperable required support or supported systems or components that are associated with the other train that has power, results in starting the completion times for the Action. The specified time is acceptable because it minimizes risk while allowing time for restoration before subjecting the unit to transients associated with shutdown.
The remaining OPERABLE AC supplies (one offsite circuit and three DGs for Condition (a), two offsite circuits and two DGs for Condition (b), or three DGs for Condition (d)) are adequate to supply electrical power to the onsite Class 1E Distribution System. Thus, on a component basis, single failure protection for the required system or component's function may have been lost; however, function has not been lost. The completion time takes into account the component OPERABILITY of the redundant counterpart to the inoperable required system or component. Additionally, the completion time takes into account the capacity and capability of the remaining AC sources, a reasonable time for repairs, and the low probability of a DBA occurring during this period.
