-License Nos. NPF-41 and NPF 4 1

.This'special r hort is required. by Palo Verde Unit 1 Technical Specification 3.4.4

~

section 4.4.4'.5 REPORTS a, ~ within 15 days following the ~ completion of each inservice

inspection of, steam generator tubes.

On February 17, 1987, Palo Verde Unit 1 was in Mode 5 (COLD SHUTDOWN), when an inservice inspection of_both steam generators was completed. The inspection resulted in the plugging of 20 tubes in steam generator number 1 and 14 tubes in steam generator number 2.

The complete results of the steam generator _ tube inservice inspection will be submitted to the Commission in a Special Report within 12 months ~following completion of the inspection as required by Technical Specification section 4.4.4.5 REPORTS b.

Unit 2 was also in Mode 5 (COLD SHUTDOWN) at this time. 'A management decision was

.made to inspect the steam generator tubes in the areas that tubes were plugged in Unit 1. There were 30 tubes plugged in steam generator number 1 and 21 tubes plugged in' steam generator number 2.

This was not an inservice inspection in Unit 2, but a voluntary, prudent management action in an effort to prevent future tube leaks. Therefore, this is a voluntary section of the report and is not required by Technical Specifications.
