Enclesure SUPPLEMENTAL RESPONSE TO NOTICE OF VIOLATION IN IE INSPECTION REPORT NO. 50-338/79-47 A.

NRC Comment:

As required by Criterion V of Appendix B to 10 CFR 50 and implemented by Vepco Topical Report VEP-1-A Section 17, paragraph 17.2.5 specifies in part, that activities affecting quality are accomplished in accordance with instructions, procedures, and drawings.

General Welding Procedure W-1.0 Rev. 1 invokes ASME Section IX (74.W76) which under paragraph QW-2013, requires that each welding process or procedure be qualified either separately or in combination with other processes or procedures

...for the deposited weld metal thickness range for each of the processes or procedures... paragraph QW-351 of the same code requires that the limit of thickness of the weld he deposits with each welding process.

Contrary to the above, on November 16, 1979, procedure qualification records of weld process specifications and welder performance qualifi-cations involving combination processes did not indicate the weld metal thickness deposited with each welding process.

This is an infraction.

Response

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 steps taken and results achieved:

The North Anna welder performance qualifications involving combined processes now show separate thicknesses for each process of a com-bined process weld.

2.

Corrective steps which will be taken to avoid further noncompliance:

We believe no further corrective action is required on this item.

3.

DatewhenfullcompliancewillbeaEhieved:

l Full compliance was achieved October 13, 1980.
