l-APPENDIX A NOTICE OF VIOLATION Houston Lighting & Power Company Dockets:
50-498 South Texas Project, Units 1 and 2 50-499 Operating License: NPF-76 Construction Permit: CPPR-129 During an NRC inspection conducteo on June 27 through July 1, 1988, a violation of NRC requirements was identified. The violation involved failure to follow instructions for measuring remaining pipe wall thickness.
In accordance with the "General Statement of Policy and Procedure for NRC Enforcement Actions,"
10 CFR Part 2, Appendix C (1988), the violation is listed below:
Criterion V of Appendix B to 10 CFR Part 50 requires that activities affecting quality shall be prescribed by documented instructions of a type appropriate to the circumstances and shall be accomplished in accordance with those instructions. This requirement is amplified by the approved Quality A surance Program Description (QAPD) of the South Texas Project.
A nonconformance report, NCR SS-05553, required the removal of a magnetic particle examination indication from pipe spool AF-2012-H.
instructions of the nonconformance report were to excavate the indication but not go below a remaining wall thickness of 0.437 inch.
Contrary to the above, NCR SS-05553 was improperly closed ir. that ultrasonic thickness measurements, made after quality control (QC) closecut of the NCR, showed that the actual remaining wall thickness in the excavation area was 0.418 inch.
Initial QC acceptance was determined subsequently to have been the result of use of an incorrect inspection method (i.e., estimating remaining wall thickness by subtracting depth of excavation from pipe nominal wall thickness).
This is a Severity Level IV violation.
(SupplementII.D)(498/8838-01; 499/8838-01)
Pursuant to the provisions of 10 CFR 2.201, Houston Lighting & Power Company is hereby required to submit to this office, within 30 days of the date of the letter transmitting this Notice, a written statement or explanation in reply, including for each violation:
(1) the reason for the violation if admitted, the corrective steps which have been taken and the results achieved, the corrective steps which will be taken to avoid further violations, and the date when full compliance will be achieved. Where good cause is shown, consideration will be given to extending the response time.
Dated at Arlington, Texas, this d ot/v day of 1988.
