With regard to Mr. R. C.

,, . DUKE POWER COMPANY GCONEE NUCLEAR STATION Response to inspection Report 50-269/79-26, -270/79-24, -287/79-26 ITEM As required by 10CFR50, Appendix B, Criterion V, Instructions, Procedures and Drawings," activities affecting quality shall be prescribed by documented in-structions . . . and shall be accomplished in accordance with these instruc-tions . . ." The accepted Quality Assurance Program, Duke-1, states in part,

" Procurement of materials, parts, and components . . . controlled . . . to as-sure that the safety of the station is not compromised." Also, Administrative Policy Manual 4.5 that implements the Quality Assurance Program states, "Each purchase specification shall be prepared by a qualified individual who shall assure that all applicable requirements are included, and shall be reviewed .

. . to assure accuracy of content."

Contrary to the above, Purchase Order No. C60920, dated July 12, 1976, was pre-pared and issued for material that did not meet the requirements for use at Oconee Nuclear Station. Specifically o-rings for the reactor vessel head had 16 slots instead of 12, and the o-ring diameter was 0.5 inches instead of 0.455 inches.

This is an infraction and applies to the three Oconee units.

RESPONSE

This infraction resulted from an administrative deficiency in that the material procurement program did not require a new review after a change was made to the original material requisition. The program has since been revised to require any changes to a requisition (for safety-related material) to be documented on an addendum with the same level of review as the original requisition.

The program also provides for Quality Assurance review of requisitions for safety related material to ensure all applicable specifications are included.

As stated in the inspection report, all of the incorrect o-rings on site have been destroyed. The correct type o-rings have been procured.

ITEM Technical Specification 6.4.l(e) requires preventative or corrective maintenance to be in accordance with approved written procedures.

Contrary to the above, the reactor vessel o-rings for Unit I were not installed in accordance with procedure MP/0/A/1150/09, on September 29, 1978.

This is an infraction and applies to Oconee Unit 1. .

RESPONSE

i871 533 After discovery of this infraction, the Unit I reactor vessel o-ring was prop-crly installed. The individuals involved in the faulty installation were coun-seled and appropriate disciplinary action was taken. All Maintenance personnel were counseled on the importance of following procedures as written. The o-ring installation procedure was revised to (a) provide a proper installation drawing, (b) include a sign-off step for a qualified maintenance supervisor or engineer to verify proper placement of the o-ring and retaining clips, and (c) provide far supervisor review of the procedure with his crew prior to installation.
