VERMONT YANKEE NUCLEAR POWER CORPORATION 2.C.2.1 FVY 83-73 RD 5. Box 169, Ferry Road, Brattleboro, VT 05301 yggo ENGINEERING OFFICE 1671 WORCESTER ROAD FRAMINGHAM, MASSACHUSETTS 01701 July 13,1983 TELEPHONE 6t F-672-et00 U.S. Nuclear Regulatory Commission Region I 631 Park Avenue King of Prussia, PA 19406 Attention:
Mr. Richard W. Starostecki, Director Division of Project and Resident Programs
Reference:
(a) License No. DPR-28 (Docket No. 50-271)
(b) USNRC Letter to VYNPC, dated June 6, 1983 and Inspection Report 83-09
Dear Sir:
Subject:
Response to Inspection No. 50-271/83-09 (Violation 83-09-01)
This letter is written in response to Reference (b) which indicates that one of our activities was not conducted in full compliance with Nuclear Regulatory requirements. This alleged Level V violation was identified as a result of an inspection conducted on April 12 - May 3,1983, by your Mr. W.J. Raymond.
Information is submitted as follows in answer to the alleged violation con-tained in the appendix to your letter.
Item:
The Installation and Test Procedure for Torus Internal Modifications is SPN-70115-700, Revision 0.
Step 7.4.4 of this procedure states:
"After cutting to proper size and shape, gusset plate will be fitted to specified location and tacked in place per WPS-BG, Revision 0 as shown on Drawing No. WM-70115-100."
Contary to the above, approximately 107 of the 144 gusset plates were tacked in place using welding procedure WPS-B. The failure to ade-quately control the welding of gusset plates is considered a viola-tion.

Response
Although the text of the installation procedure reflected the use of WPS-BG, the drawing used by the craftsman, which was reviewed as part of the installation and test procedure, indicated that WPS-B could also be used. As noted in the inspection report either welding procedure was previously determined to be tech-nically acceptable. As such we disagree with the inspector's conclusion that a lack of control over the actual welding existed. We do acknowledge that we failed to properly include reference to WPS-B in the text of the procedure and accordingly have reinstructed all personnel involved in the need to insure the compatability of procedures and their appended drawings.
The use of WPS-B has been reflected in the text of the installation procedure.
We trust that this information will be satisfactory.
If you have any further questions or need additional information, please contact us.
Very truly yours, VERMONT YANKEE NUCLEAR POWER CORPORATION fa, e
