ORGANIZATION:
WESTINGHOUSE ELECTRIC CORPORATION, INDUSTRIAL & GOVERNMENT TUBE DIVISION HORSEHEADS, NEW YORK REPORT NO.: 99900324/81-01 INSPECTION RESULTS:
PAGE 3 of 5 The inspector reviewed section 4 of the Quality Program Manual (QPM) and three purchase orders.
Subsequent to the WI>D January 7, 1980, response to Deviation C (79-01)
QPM had been rewritten.
Section 4 delineates the control of Purchases and contains a checklist form ET-2662R4 designed to prevent the above deficiency for a Code or safety-related item or service.
The P.O.s reviewed indicate that this new system has been implemented.
4.
(Closed) Deviation D (79-01):
A purchased item, identified by incoming inspection on Material Review Notice (MRN) 4131 as being too short, was released to manufacturing without receipt of the pink copy containing the required QC ANI and approvals for the proposed accept-as-is disposition.
The white copy of MRN 4131 was retained by incoming inspection and did not remain with the item.
The inspector reviewed section 10 of the QPM and identified the QPM was rewritten subsequent to the WI>D January 7, 1980, response to Deviation D (79-01).
Section 10 delineates Nonconformances & Correc-tive Action which covers the use of the MRN.
Section 10 as presently written resolves the Deviation D (79-01) deficiency.
5.
(0 pen) Unrese?"ed Item I.C.3.c. (79-01):
Deficient soldered pin connectors require repair (dPPSS, WNP-2).
Evidence could not be presented that:
(1) the WPPSS, WNP-2 EPA installa-tion, repair, and checkout were final; (2) that WI>D had analyzed the defective EPA's or had initiated activities to preclude reoccurence of this type; and (3) that"the evaluation of the WNP-2 Project EPA deficiencies had been performed under 10 CFR Part 21.
(See nonconformance.).
6.
(Closed) Unresolved Item I.G.3.b.:
Purchase Order failed to adequately and c.oherently identify all required codes and standards requirements for procurement of electrical cable for electrical penetration assemblies.
Subsequent to the inspection a review of three purchase orders was made with the concurrence of the initiator of the original deficiency.
From this review, it was determincd that these purchase orders adequately and coherently identify all required codes and standards requirements for procurement of electrical cable for electrical penetration assemblies.
7.
(Closed) Unresolved Item II.B.3.b..
Absence of temperature measurement equipment in production welding area to provide capability for measure-ment of preheat and interpass temperatures.
The inspector observed a temperature gauge (0mega CR/C Type E T/C Serial No. 5283) which was assigned to the production welding area to measure preheat and interpass temperatures.
8.
(Closed) Unresolved Item II.B.3.b.:
Inadequate definition of scope of QA program procurement controls applicable to different categories of electri-cal penetration assembly items.
ORGANIZATION:. WESTINGHOUSE ELECTRIC CORPORATION, INDUSTRIAL & GOVERNMENT TUBE DIVISION HORSEHEADS, NEW YORK REPORT NO.: 99900324/81-01 INSPECTION RESULTS:
PAGE 4 of 5 The inspector reviewed QPM sections 4 and 7, and Quality Control Procedure (QCP) 4-10.
Subsequent to the 79-01 inspection, the QPM was rewritten.
In the new QPM, section 4 defines the applicable procurement document controls and establishes a controlled vendor approval system.
QPM section 7 in conjunction with QCP 4-10 defines the receiving inspection criteria.
These documents combine to clarify the scope of procurement controls applicable to different boundary materials, nonpressure boundary (safety-related) and nonpressure boundary (nonsafety-related).
9.
(Closed) Unresolved Item II.E.3.b.:
Near distance acaity test card used for vision examinations of NDE personnel could not be clearly established as being the required Jaeger J-1.
The inspector examined two near distance acuity test cards, and reviewed six physical examination records.
Two Jaeger J-1 Reading Cards were used to administer visual examinations:
(1) Reading Card (Metric) by American Society for Nondestructive Testing, Columbus, Ohio, Janaury 1978; and (2) Reading Card Bausch & Lomb, Rochester, New York 14602, 713565-101, IM-X-69.
Review of the six individual inspec-tion personnel Physical Examination Records for six inspection personnel showed that all had been reexamined with the above near distance acuity test Jaeger J-1 test cards between August 16, 1979, and August 21. 1979.
E.
OTHER FINDINGS OR COMMENTS:
1.
Regional Requests a.
A potential Construction Deficiency Report was issued by HL&P, STP, pertaining to the insulation on the wire bundle of one electrical pene-tration being cut and exposing several conductors.
In the November 13, 1981, final report HL&P determined that this was nonreportable and a safety hazard did not exist.
WI>D on December 16, 1981, completed i
a ET-2550 (10 CFR Part 21 evaluation) forra and concurred with the HL&P resolution; i.e., repair damaged jacketing with qualified heat I
shrink sleeve material and test, recurrence control not deemed neces-sary.
1 b.
A July 21, 1981, 10 CFR Part 50.55(e) Report made by Southern California Edison Company stated, "During an investigation of vendor installed series N coaxial connectors located in the Unit 2 Electrical Containment Penetrations, copper wire rings (18 gauge) were found in the female jack connectors, apparently being used as spacers.
This provided inconsistent clearance between the face of the connector jack and the end of the center conductor female contact, resulting in a mating problem between the connector jack and plug.
Nonconformance reports for Units 2 and 3 were issued to correct the assembly inter-ference that existed between the center female conductor pin and the face of the connector jack.
In the process of implementing the dis-position of the nonconformance reports, the additional conditions of improper assembly which are noted below were discovered."
V ORGANIZATION: WESTINGHOUSE ELECTRIC CORPORATION, INDUSTRIAL & GOVERNMENT TUBE DIVISION HORSEHEADS, NEW YORK REPORT NO.: 99900324/81-01 INSPECTION RESULTS:
PAGE 5 of 5 In an October 8, 1981 memo to Bechtel Power Corporation, WI>D takes the position that they assembled the coaxial connectors in accordance with their manufacturing drawings and specifications which do not use any copper wire rings, and the rings used as spacers were added without WI>D approval.
On December 11, 1981, WI>D initiated Product Change Notice 1377 "to provide inspection instructions on pin location of Coax connector."
c.
A 10 CFR Part 50.55(e) Deficiency Report made by HL&P, STP, stated that HL&P was advised by letter from Westinghouse that Rockbestos had identified to them (WI>D) a potential for failure of certain coaxial cables.
WI>D supplied EPAs and N-16 Junction Boxes (WL-24051) using the cable.
W has notified their customers of the deficiency.
W NES plans to riin a qualification LOCA test to determine capability of the 24040 (similar to 24051).
WI>D oven testing on September 4, 1981, simulating high energy line break (HELB) caused a short in one cable and a low resistance on another.
2.
Implementation of 10 CFR Part 21 Reviewed WI>D Process Spec. No. 252-1-38, Revision C, dated December 14, 1981, Reporting of Defects and Noncompliance to verify that procedures had been written in compliance with paragraph 21.21 of 10 CFR Part 21.
The above procedure had been written but not complied with (see nonconfor-mance).
Posting of 10 CFR Part 21 was observed and found to be in com-pliance with paragraph 21.6 of 10 CFR Part 21.
3.
Follow-up Items The results of the LOCA testing in paragraph E.1.c. and planned corrective actions for the coaxial cable deficiency will be reviewed during a sub-sequent inspection.
