l DUKE POWER COMPANY CATAWBA NUCLEAR STATION UNITS I and 2 USNRC IE REPORT 50-413, 414/82-07 RESPONSE TO VIOLATION i

VIOLATION 10 CFR 50, Appendix B, Criterion V, as implemented by Topical Report Duke 1-A, Section 17, paragraph 17.1.5 requires that activities affecting quality be prescribed by documented procedures appropriate to the circumstances.

Contrary to the above, an activity affecting quality was not prescribed by documented procedures on March 16, 1982 in that existing procedures did not preclude alteration of repair weld cavities af ter inspection had been performed. This resulted in alteration of a repair cavity for weld no. INC234-12 after inspection and rewelding without obtaining additional inspection.

RESPONSE

I. We admit the violation.

2. The reason the violation occurred is that the welder deter-mined alteration of the repair cavity was required in order to achieve a quality weld. Procedures establish require-ments for repair cavity geometry but do not provide for al teration of geometry af ter inspection.

3. Corrective action taken to date is:

a. Welders have been instructed to notify inspectors af ter alteration of previously accepted fit up geometries.

b. The weld in question has been determined to be acceptable on the basis of radiography.

4. Corrective action to be performed is to revise appro-priate procedures to limit alterations of repair cavity geometry af ter inspection.

5. Full compliance will be achieved by November 1, 1982.
