e Attachment (Revised)

RESPONSE TO NON-COC LIANCE ITEM REPORTED IN IE INSPECTION REPORT NO. 50-338/79-40 A. NRC Comment As required by Criterion V of Appendix B to 10 CFR 50 and as implemented by Section 5 of VEPC0 Nuclear Power Station Quality Assurance Manual, " Activities af fecting quality shall be prescribed by documented instructions, procedures and drawings . . . . and shall be accomplished in accordance with these instruc-tions, procedures and drawings." Paragraph 3. 3 of W-NSD Procedure ISI-11, the applicable procedure for liquid penetrant surface inspection during inservice inspection, requires removal of excess penetrant prior to development.

Contrary to the above, on October 11, 1979, for velds 5, 7, 8, 9 and 10 on ISO VRA-1-4109, excess penetrant was not adequately removed resulting in a surface too pink for proper evaluation. The level II examiner accepted the test as a valid test.

This is an infraction.

Response

The above infraction is correct as stated. Specifically, pursuant to Section 2.201 of the NRC's " Rules of Practice" Part 2, Title 10, Code of Federal Regulations, the following information is submitted.

1. Corrective stens taken and results achieved:

The welds in question were satisfactorily reexamined on October 12, 1979.

Surveillance was conducted on several subsequent examinations and they were also performed satisfactorily.

2. Corrective steps which will be taken to avoid further non-compliance:

The contractor involved was cautioned chat the quality of liquid pene-trant testing must be improved and in the future, contractors will have more surveillance by Vepco NDT personnel during liquid penetrant testing.

This particular problem was discussed with the specific contractor employee. Surveillance of his work indicated that the problem was corrected.

The individual involved performed a total of 39 examinations. Eleven (11) of these examinations (which includes the five welds listed above) will be reexamined.

3. Date when full compliance will be achieved:

Full compliance will be achieved on December 31, 19 79.
