ATTACHMENT I DESCRIPTION AND ASSESSMENT
1.0 DESCRIPTION
The proposed amendment would modify technical specifications (TS) requirements for missed surveillances in SR 3.0.3.
The changes are consistent with Nuclear Regulatory Commission (NRC) approved Industry/Technical Specification Task Force (TSTF) STS change TSTF-358 Revision 5, as modified by Federal Register Notice 66FR32400, of June 14, 2001, and in response to public comments. The availability of the TS improvement was published in the Federal Register on Friday, September 28, 2001 as part of the consolidated line item improvement process (CLIIP).
2.0 ASSESSMENT
2.1 Applicability of Published Safety Evaluation Southern California Edison (SCE) has reviewed the safety evaluation dated June 8, 2001 (published June 14, 2001) as part of the CLIIP. This review included a review of the NRC staff's evaluation, as well as the supporting information provided to support TSTF-358. SCE has concluded that the justifications presented in the TSTF proposal and the safety evaluation prepared by the NRC staff are applicable to San Onofre Nuclear Generating Station Units 2 and 3 (SONGS 2 and 3) and justify this amendment for the incorporation of the changes to the SONGS 2 and 3 TS.
2.2 Optional Changes and Variations SCE is not proposing any variations or deviations from the TS changes described in the fully modified TSTF-358 Revision 5 or the NRC staff's model safety evaluation dated June 8, 2001 (published June 14, 2001).
3.0 REGULATORY ANALYSIS
3.1 No Significant Hazards Consideration Determination Southern California Edison (SCE) has reviewed the proposed no significant hazards consideration determination (NSHCD) published in the Federal Register as part of the Consolidated Line Item Improvement Process. SCE has concluded that the proposed NSHCD presented in the Federal Register notice is applicable to San Onofre Nuclear Generating Station Units 2 and 3 and is hereby incorporated by reference to satisfy the requirements of 10 CFR 50.91(a).
3.2 Verification and Commitments As discussed in the notice of availability published in the Federal Register on September 28, 2001 for this TS improvement, plant-specific verifications were performed as follows:
SCE has established TS Bases for SR 3.0.3 which state that use of the delay period established by Surveillance Requirement 3.0.3 is a flexibility which is not intended to be used as an operational convenience to extend surveillance intervals, but only for the performance of missed surveillances.
The modification will also include changes to the Bases for SR 3.0.3 that provide details on how to implement the new requirements. The Bases changes provide guidance for surveillance frequencies that are not based on time intervals but are based on specified unit conditions, operating situations, or requirements of regulations. In addition, the Bases changes state that SCE is expected to perform a missed surveillance test at the first reasonable opportunity, taking into account appropriate considerations, such as the impact on plant risk and accident analysis assumptions, consideration of unit conditions, planning, availability of personnel, and the time required to perform the surveillance.
The Bases also state that the risk impact should be managed through the program in place to implement 10 CFR 50.65(a)(4) and its implementation guidance, NRC Regulatory Guide 1.182, "Assessing and Managing Risks Before Maintenance Activities at Nuclear Power Plants," and that the missed surveillance should be treated as an emergent condition, as discussed in Regulatory Guide 1.182. In addition, the Bases state that the degree of depth and rigor of the evaluation should be commensurate with the importance of the component and that missed surveillances for important components should be analyzed quantitatively. The Bases also state that the results of the risk evaluation determine the safest course of action. In addition, the Bases state that all missed surveillances will be placed in the licensee's Corrective Action Program.
Finally, SCE has a Bases Control Program consistent with Section 5.5 of the STS.
4.0 ENVIRONMENTAL EVALUATION SCE has reviewed the environmental evaluation included in the model safety evaluation dated June 8, 2001 (published June 14, 2001) as part of the CLIIP. SCE has concluded that the staff s findings presented in that evaluation are applicable to SONGS 2 and 3 and the evaluation is hereby incorporated by reference for this application.

The basis for this delay period includes consideration of unit conditions, adequate planning, availability of personnel, the time required to perform the Surveillance, the safety significance of the delay in completing the required Surveillance, and the recognition that the most probable result of any particular Surveillance being performed is the verification of conformance with the requirements.

SR Applicability B 3.0 BASES (continued)
SR 3.0.3 Completion of the Surveillance within the delay period (continued) allowed by this Specification, or within the Completion Time of the ACTIONS, restores compliance with SR 3.0.1.
SR 3.0.4 SR 3.0.4 establishes the requirement that all applicable SRs must be met before entry into a MODE or other specified Condition in the Applicability.
This Specification ensures that system and component OPERABILITY requirements and variable limits are met before entry into MODES or other specified conditions in the Applicability for which these systems and components ensure safe operation of the unit.
This Specification applies to changes in MODES or other specified conditions in the Applicability associated with unit shutdown as well as startup.
The provisions of SR 3.0.4 shall not prevent changes in MODES or other specified conditions in the Applicability that are required to comply with ACTIONS.
The precise requirements for performance of SRs are specified such that exceptions to SR 3.0.4 are not necessary.
The specific time frames and conditions necessary for meeting the SRs are specified in the Frequency, in the Surveillance, or both.
This allows performance of Surveillances when the prerequisite condition(s) specified in a Surveillance procedure require entry into the MODE or other specified condition in the Applicability of the associated LCO prior to the performance or completion of a Surveillance.
A Surveillance that could not be performed until after entering the LCO Applicability, would have its Frequency specified such that it is not "due" until the specific conditions needed are met.
Alternately, the Surveillance may be stated in the form of a Note as not required (to be met or performed) until a particular event, condition, or time has been reached.
Further discussion of the specific formats of SRs' annotation is found in Section 1.4, Frequency.

This allows performance of Surveillances when the prerequisite condition(s) specified in a Surveillance procedure require entry into the MODE or other specified condition in the Applicability of the associated LCO prior to the performance or completion of a Surveillance.
A Surveillance that could not be performed until after entering the LCO Applicability, would have its Frequency specified such that it is not "due" until the specific conditions needed are met.
Alternately, the Surveillance may be stated in the form of a Note as not required (to be met or performed) until a particular event, condition, or time has been reached.
Further discussion of the specific formats of SRs' annotation is found in Section 1.4, Frequency.
