DEFICIENCY REPORT (10CFR Part 50, Paragraph 55 (e) )
Report No.
1 Unit Millstone Unit 3 Final Interim X
Date Final Report Due on or before August 18, 1976 Date Deficiency Identified December 19, 1975 1.
Description of Deficiency Throughout the final quarter of 1975 concerns regarding the performance of our prime vendor for shop fabricated piping (Tubeco, Inc.) were brought to our attention. During this time period, the high final product rejection rate led to speculation about a possible breakdown in the manufacturer's Quality Assurance Program.
On November 19,-21, 1975, Stone & Webster Engineering Corporation (S & W), as agent for the~ owner, performed a routine procurement quality control (PQC) audit at the manufacturer's facility. The audit concluded that the manufacturer is generally not in compliance with all of the requirements of the purchase order and applicable portions of their own Quality Assurance program. The audit results were transmitted to the manufacturer for appropriate resolution within 30 days after receipt.
As a result of inadequate resolution of the audit findings coupled with the continuation of identified problems, a stop vork order was issued to the manufacturer on December 19, 1975. Upon being formally appraised of all concerns, it was determined, subsequet tly, that a reportable deficiency indeed existed. Per 10CFR 50.55 (e), your Messrs. R. Haynes and R. Keimig of the Office of Inspection and Enforcement werc notified accordingly on January 15 and 19 respectively about a breakdown in a portion of the manufacturer's Quality Assurance Program as applied to the subject unit.
2.
Safety implications The purchase order for shop fabricated piping placed with Tubeco, Inc. includes both safety and non-safety related piping. Tubeco elected to perform all of its. activities under the quality assurance requirements of 10CFR 50 Appendix.B.

s Although the breakdown of the Quality Assurance program was based on audit findings relating only to non-nuclear safety piple-g fabr2 cat ion, continuation of piping fabric.ation in this manner could have led to adverse safety implications if safety related piping were involved.
3.
Corrective Measures Subsequent to the issue of the stop work order, a meeting between responsible S & W and Tubaco persor.nel was held on January 5, 1976 to discuss future activities on the shop fabricated piping purchase order. As a result i
of the meeting, the following corrective measures will be instituted:
1.
Tubeco is to respond to all corrective action items found during
'the PQC audit in a satisfactory manner, 2.
Tubeco is to permit the institution of additional inspection activities by S & W PQC personnel as deemed appropriate by S & W 3.
A written agreement, signed by Tubeco, recognizing the final resolutions ar.d conditions of the release of the stop work order, will be required prior to the release taking effect.
It is believed that the implementation of the above corrective measures will ensure I
compliance of the shop fabricated piping with the requirements of the purchase order and applicable portions of the manufacturer's Quality Assurance Program.
l A final written report confirming program adequacy will be submitted in the future.
