July 6, 1984 MEMORANDUM-FOR: Raymond F. Fraley Executive Director, ACRS FRON:

Richard H. Vollmer, Director, Division of Engineering, NRR

SUBJECT:

DIABLO CANYON LICENSE CONDITIONS ON PIPING AND SUPPORTS When Diablo Canyon Unit I was granted a low power license, certain. con-ditions on full power operation were imposed. The activities required by these license conditions have been completed by the licensee and evaluated by the Diablo Canyon Peer Review Group. Draft reports of the Group's evaluations are enclosed for consideration by the ACRS.

Although not license conditions, two other issues have been considered by the Group. One concerns the adequacy of the Diablo Canyon Independent Design Verification Program in the area of piping and supports and the other deals with certain programmatic issues. The Group findings on those matters are also enclosed.

We will be prepared to address these issues in detail at the Sbcommittee meeting on July 11 and at the full Committee meeting on July 13. We would appreciate the Comittee views on the Group's findings and whether these issues should prevent operation of Diablo Canyon Unit 1 at full power.
