APPENDIX A Farwell & Hendricks, Inc.
Docket No. 99900918/90-01 NOTICE OF NONCONFORMANCE Based on the results of an NRC inspection conducted on June 25-27, 1990, it appears that certain cf your activities were not in accordance with NRC requirements which were imposed on you through purchase order contracts with NRC licensees:
A.
Criterion III of Appendix B to 10 CFR Part 50, " Design Control," requires, in part, that measures shall be established for the selection and review for suitability of application of materials, parts, equipment, and processes that are essential to the safety-related functions of the structures, sys-tems and components. Criterion III also requires, in part, that design control measures shall arovide for verifying or checking the adequacy of design. One of the met 1ods of design verification stated is performance of a suitable testing' program.
Farwell&Hendricks.(F&H)TechricalProcedure(TP)3-001, Revision 0,
" Procedure for Estalaishment and Procurement of Commercial-Grade Items For Use as Basic Component," Section 5.2, " Dedication" describes the dedica-tion process used by F&H. Ten subsections go into detail in areas as such as: determination of critical characteristics, supplier /
manufacturer selection, design, materials of construction, manufacturing 1
process, environmental and seismic qualification, and QA verification.
i Section 5.0.2.1, Determination of Critical Characteristics, requires that the engineer identify and quantify critical characteristics essential to the-item's performance-of its safety function and lists L
" dimensions" as an example of such characteristics.
1 Section 5.2.2.3, Design, requires the engineer to determine'any inspection, condition, and/or functional test requirements necessary to assure the item will perform its function.
Section 5.2.2.4, Materials of Construction, states that the manufacturer 1
of replacement parts may provide the materials of construction or a test analysis can be performed to determine the materials of the replacement i
item.

NOV 091980 Contrary to the above, Farwell and Hendricks sold the following items as nuclear safety-related without completely evaluating their suitability for use in such applications:
74001, and 74003.3 - F&H procured 60447.1,74000,(MCCBs)ascommercial-grade, items (CGis),
1.
Data Packages molded case circuit breakers processed them through their program for dedication of consnercial-gradeMCCBsforClass1E(safety-related)nuclearplantservice,and sold them to a nuclear utility, certifying their suitability for such service, without conducting a complete review for suitability of application to the safety-related functions. Also, F&H did not completely verif the adequacy of design through a suitable testing program in that 1) not all critical characteristics were verified by the program, 2) the acceptance criteria for some testing were 1
inadequate to verify the applicable critical characteristics
]
(3) not all MCCBs to be dedicated were tested at all, and (4} not all items' performance was consistent with the stated basis for the acceptance criteria.
Also, F&H's measures for control of purchased material were not adequate to assure that cossnercial-grade MCCBs to be dedicated for safety-related service conformed to the procurement documents in that verifiable, documented traceability of a certain MCCB to the original circuit breaker manufacturer (CBM) and to objective quality evidence furnished by the CBM was not established.
2.
Data Package 60500 - F&H purchased 20 amp Bussmann fuses:as connercial-grade items and sold them as safety-related dedicated items without verifying the actual dimensions of the fuses. The dimensions are critical characteristics which should have been verified.
F&H did verify the dimensions of the fuse holders. 'This dedication was completed in April 1989.
3.
Data Package 60058 - F&H purchased Norgren poppet valves as l
commercial-grade items and sold them as a safety-related dedicated items without verifying that the coil materials were suitable for a mild environment or a seismic application. This dedication was completed in September 1986.
Data Package 60600 for a coil purchased from Norgren and dedicated in May 1989 did attempt to verify.the coil materials as part of verification.

NOV 0 91330 Mr. John R. Hendricks 2
In accordance with 10 CFR 2.790 of the NRC's " Rules of Practice " a copy of this letter and its enclosures will be placed in the NRC Public Document Room.
i Should you have questions concerning this inspection, we will be pleased to discuss them with you.
