SUMMARY

Generic Letter 83-28 describes the intermediate term actions to be taken by 1

licensees and applicants to address the generic issues raised by the two ATWS events that occurred at Unit 1 of Salem Nuclear Power Plant.

This report is an evaluation of the responses submitted by Arizona Public Service Company, the licensee for the Palo Verde Nuclear Generating Station, Unit 1 for Items 3. 1.3 and 3.2.3 of the Generic Letter.

The actual documents reviewed as part of this evaluation are listed in the references at the end of this report.

The requirements for these two items are identical with the exception that Item

3. 1.3 applies these requirements to the Reactor Trip System components and Item 3.2.3 applies them to all other safety-related components.

Because of this similarity, the responses to both items were evaluated together.

EIEEIEENENT Licensees and applicants shall identify, if applicable, any post-maintenance test requirements in existing Technical Specifications which can be demonstrated to degrade rather than enhance safety.

Appropriate changes to these test re-quirements, with supporting justification, shall be submitted for staff approval.

EVALUATION The licensee for the Palo Verde Nuclear Generating Station, Unit 1 responded to these requirements with a submittal dated November 3, 1983 The licensee stated in this submittal that there were no post-maintenance testing require-ments in Technical Specifications for either reactor trip system or other safety-related components which degraded safety.

CONCLUSION Based on the licensee's statement that no post-maintenance test requirements were found in Technical Specifications that degraded

safety, we find the licensee's responses acceptable for Items 3. 1.3 and 3.2.3 of Generic Letter 83-28.
