1. The material presented at the meeting by SCE are given in Enclosure 2.

The purpose of the meeting was to present a proposed change in the Unit 2 Technical Specifications which would extend the surveillance interval for the ESFAS subgroup relays from 6 months to 18 months.

Following a discussion of the issue, the NRC staff stated that the following additional information would be required to support the proposed Technical Specification change:

A. Provide a list of ESF relays and the components associated with each that:

1. Cannot be tested at power.
2. Can be tested at power but only by manually defeating and subsequently restoring, the ESF train.
3. Can be tested at power without defeating the ESF train, but are operationally burdensome to test.

B. Provide a justification for the 18 month testing frequency, considering:

1. Conformance to IEEE-338.
2. Quantification of degradation of availability on demand.
3. The benefits of increasing the testing interval to 18 months from the standpoint of:

(a) Safety (b) Cost Original Signed By:
