' Page - 1 Violation ~(482/8632-01): Failure Of lost-Test Review to Identify An'Out-Of-Specification Value And Institute Proper Corrective Action Finding:

Wolf Creek Generating Station (NCGS) TS 6.8.1 requires that, " Written procedures shall be established, implemented, and maintained covering . . ..

a. The applicable procedures reconnended in Appendix A of Regulatory Guide 1.33, Revision 2, February 1978."

Section 8.b.of Appendix A to Regulatory Guide 1.33 requires that specific procedures for surveillance tests, inspections, and calibrations are to~be provided.

Plant Adninistrative Procedure (ADM)02-300, . Revision 8, " Surveillance Testing," has been established and inplemented in accordance with these requirements.

Step 5.6.~2 requires that each test reviewer shall ensure that, " Test data shall be compared to the acceptance criteria to determine test acceptability."

Contrary to the above, during the post-test review of STS MT-019, dated October 16, 1985, the reviewers failed to identify and take appropriate corrective action to restore the "as listed" out-of-specification value of the average specific gravity to within limits.

Reason For Violation If A&nitted:

Failure to identify and take appropriate corrective action to restore the "as-listed" out-of-specification value of the average specific gravity to within limits was due to failure to follow adminstrative procedure ADM 02-300, " Surveillance Testing". Step 5.6.2 of this procedure requires that post test reviewers conpare test data to the acceptance criteria to determine test acceptability.

Corrective Steps Which Have Been Taken and Results Achieved:

The personnel who failed to identify and take corrective actions during the post test review have been counseled on the inportance of the reviews they perform. In addition, a review of the calculations performed for the surveillance procedure determined that the average specific gravity was incorrectly listed on pages 7 and 11 of STS MT-019. A Supplemental Correction Report has been conpleted and vaulted to correct the data on pages 7 and 11 of the surveillance test procedure.

As a result of that evaluation the Superintendent of Maintenance has.. issued written direction which requires an additional post ~ test review be performM by a Maintenance Engineer, for conpleteness and- to ensure all data is within acceptable limits prior to
