-08/22/2008; San Onofre Nuclear Generating Station; Temporary Instruction 2515/171, "Verification of Site Specific Implementation of B.5.b Phase 2 and 3 Mitigating Strategies." This report covered a 5-day announced inspection in accordance with Temporary Instruction 2515/171, "Verification of Site Specific Implementation of B.5.b Phase 2 and 3 Mitigating Strategies." The inspection was conducted by a Region IV senior resident inspector, a Office of Nuclear Reactor Regulation inspector, and assistance was provided by one acting NRC site resident inspector.
The NRC's program for overseeing the safe operation of commercial nuclear power reactors is described in NUREG-1 649, "Reactor Oversight Process," Revision 4, dated December 2006.A. NRC-Identified and Self-Revealing Findings No findings of significance were identified.
B. Licensee-Identified Violations No findings of significance were identified.
-2-Enclosure O2F EnIINosure Report Details 4. Other Activities 40A5 Other Activities (Temporary Instruction 2515/171)The objective of Temporary Instruction 2515/171, "Verification of Site-Specific Implementation of B.5.b Phase 2 & 3 Mitigating Strategies," is to verify that the commitments for implementing the Phase 2 and 3 strategies were completed by the licensee.
The strategies for pressurized water reactors, such as San Onofre Nuclear Generating Station, are listed in Table 1 of the temporary instruction.
Inspection of all strategies listed in Table 1 was necessary to complete this temporary instruction.
The team discussed the strategies with plant staff, reviewed documentation, and, where appropriate, performed plant walk downs to evaluate whether the strategies could be implemented as stated in the licensee's submittals and the NRC safety evaluation report.For most strategies, this included verification that the strategy was feasible, procedures, and/or guidance had been developed, training had been provided to plant staff, and required equipment had been identified and staged. Specific details of the inspection activities are described below in the following sections.I 1 Proqram Reviews a. Inspection Scope Procedures:
The team examined and discussed with various plant personnel all of the station's established guidelines and implementing procedures for the B.5.b mitigation strategies.
The team assessed how the licensee coordinated and documented the interface and transition between existing off-normal and emergency operating procedures with the newly developed mitigation strategies.
The team selected a number of mitigation strategies and conducted plant walk downs with equipment operators and licensed operators to examine the adequacy and completeness of the procedures; the familiarity of the operators with the procedure objectives and specific guidance; the staging and compatibility of equipment; and the practicality of the operator actions prescribed by the procedures, consistent with the postulated scenarios.
The team also examined San Onofre Nuclear Generating Station's plans and guidance associated with coordination/

mitigation strategies.
En.qineerinq Evaluations and Calculations:

Maintenance and Testing of Equipment:
The team reviewed licensee plans and programs for periodic maintenance and testing of the equipment specified for B.5.b applications to ensure continued reliability and minimum unavailability.
