Introduction PDT of Newport News, Virginia _is a subsidiary of Grove' Engineering, Inc.' of Rockville, Maryland.
PDT was established in-1984 to provide-electrical power, distribution, maintenance and
-i refurbishment services to.the U.S. ; Navy and the utility industry.
5 Approximately 6 percent of PDT's business _in 1987 was on: safety-related breaker work activities. No molded case circuit breakers (CB's) have been refurbished for nuclear utilities although insulated case breakers have been refurbished. All electrical testing on CB's is performed on site.

'" Quality Assurance Introduction and Training."'.The-inspector-verified via' review of.QA test and attendance records;that the-.
d annual Introduction.and Training meeting-to cover all aspects of.
J the QA program was being held.. The inspector verifled.by dis-1 cussion with shop personnel that QA. project ~ briefings were being.
held to define.each individual's QA-responsibilities prior to the' initiation of a' new project. Trainifig of' PDT personnel 'is-perforraedlvia'the on-the-job training method. The: inspector noted that documentation is maintained on the breakers worked'as part of employee on-the-job training to demonstrate qualification.o No deficiencies were identified' 3.
Technical Manual Control A' review was conducted of PDT: procedure PDT-QA-07 " Document Control and Distribution."
It was noted that this procedure'did-not include' provisions for assuring that theLlatest revisions of technical manuals are obtained and used when overhauling CB's.-
Additionally, no provisions.. existed for' receiving or evaluating.
vendor. product bulletins that apply to the particular CB's being 4,
overhauled, honconformancel88-01-01 is cited in'Section B of l
this report as a result of these deficiencies.

Control of Measuring and Test Equipment (M&TE)
The inspector reviewed PDT's! A procedure PDT-QA-12, Rev. 2 Q
" Control of Measuring and Test Equipment," which applies to all M&TE used in the overhaul of nuclear safety-related or electrical apparatus built to military specifications. The; inspector reviewed the Test Equipment-History Card,. Proof. of Calibration' of tools', M&TE usage logs, and the test equipment.itself.
No j
deficiencies were identified.

Plating of Breaker Parts l
Plating of breaker parts is performed by Industrial Plating L
Corporation (IPC) of Tabbs, Virginia.
PDT's audit of IPC states that the cadmium plating is performed in accordance with Federal-Specification QQ-P-416-C and the-silver plating is performed in accordance with Federal Specification QQ-S-365C. 'The silver plating is performed on contacts and the cadmium plating is i

. performed on other breaker pieces.to prevent corrosion. The review of PDT's audit of'IPC identified no deficien'ies. The.
c inspector reviewed the Certificate of Conformance provided from IPC to PDT on~the plating of parts used for the Surry Nuclear j,
Plant safety-related breakers which were in the shop at the time L
of inspection.
No deficiencies were identified.
L 6.
Procurement Review As.part of the inspection a review wa's conducted-of PDT's.
procedure relative to the procurement of parts used in refur -
bishment operations.
PDT-QA-03, " Purchase Requisition / Order" requires that all. specialty parts be ordered from the Original Equipment Manufacturer (DEM) or from a supplier acceptable to the, particular customer involved.
Specialty parts were defined as those parts specific, to a particular breaker.such as contacts, coils, mechanism, etc. \\Nonspecialty parts would be generic parts.
such as-barstock, wire',' terminal blocks, etc.
All safety-related nonspecialty parts are required to be. ordered -
1 from vendors on the:PDT approved vendors list'in accordance with' l'
PDT-QA-10 " Source Evaluation."' A review wasidone of four random.
purchases of safety-related spare parts'.
Purchase. order.5743-Q-S.
was for:an arc chute assembly to Brown Boveri. Inc. The;P/01 invoked 10 CFR 50 Appendix B and.10 CFR Part 21.
Purchase order 704421-for arcing contacts was also for Brown Boveri, Inc. and-l similarly invoked Appendix B and Part 21.
Purchase order 5781-2-S for moving arcing contacts and a power mechanism was to l
Westinghouse NSID and invoked Appendix B and 10 CFR Part'21. No deficiencies were noted in this area, however, the PDT1 termi-nology of specialty, nonspecialty, and safety-related' parts was found to be somewhat confusing.
7.
Approved Vendor List A review was conducted of the PDT-approved vendor list.
It.was noted that companies are put on the PDT approved vendors' list based on a combination of several factors including review.of their QA manual, past performance,. or an audit.- After being put on the approved vendors list the companies are required to be audited every three years. The current PDT approved vendors list included eight companies.
No deficiencies were noted in this area.

PAGE-S'of 6-l 8.-
Analysis of Commercial Grade Parts j
The inspector reviewed three completed analyses to support the~
use of commercial-grade parts in' safety-related CB's.: The first
'1 component was an airpot overcurrent trip switch. The switch activates an auxiliary relay whose contacts provide. indication l
l that the breaker tripped on overcurrent _and also prevents reclosing of the breaker.
The second component was a wire cover for a Westinghouse'.DS-4161600. amp circuit. breaker. i The purpose i
of the wire cover is to protect the~ wiring from mechanical damage.
during removal = and installation of._the circuit breaker.: The third component was an operating link upper' pin used to connect the_ contact operating link to,the: contact operating; arm.. All commercial grade analyses were reviewed for adequacy and com-pleteness.
No inadequacies were identified.
9.
Review of Completed Work Packages A review was conducted of three completed PDT. work packages.
Job number 223 was for refurbishment / overhaul'of several ITE K-600 metal clad CB's for the Surry Nuclear Planta All replace-ment parts used in this job were traced to-safety-related. pro-curements from vendors on.PDT's approved vendors list.
It was-noted that breaker deficiencies encountered-during the overhaul' are documented in the work package by the shop mechanics; however, no documented record of_an evaluation to: solve each deficiency existed. The inspector was shown a draft-procedure-that included a new form for documenting evaluations and PDT committed to issuing the draft procedure.by November 11,1988.
Job number 145-4 was for the' refurbishment / overhaul of several Westinghouse DS-416 type metal clad _CB's fornthe Indian Point Nuclear Plant. All' spare parts were procured.from' vendors on PDT's approved vendor list.
No deficiencies were noted with l
this work package.
Job number 224 was' for refurbishment / overhaul of several L
Westinghouse DS-416 metal clad breakers'for the Indian Point Nuclear Plant.
It was noted that during the calibration check J
for the electronic overloads of these breakers,-the wrong l.
acceptance criteria were used.
For these particular overloads j
variable pickup and delay times are achieved by the setting-of two potentiometers on the overload face. Only sample (two) trip curves are provided in the technical ~ manual'for these breakers.
Each of these two curves corresponds to a particular set of pickup l

.and delay settings.
For settings other than those'shown on.the sample curves, a new curve would need to be constructed.
For this particular job, the pickup and delay settings were different from those indicated on the sample curves; yet the. sample curves 1
were.used.for deriving the. acceptance criteria. Even though-the wrong acceptance criteria were used,-the recorded trip times appeared to be within-the limits of the applicable curve for this-particular application. Additionally, it was.noted that the acceptance criteria were derived by the shop personnel without any engineering or QA input or review. -Nonconformance 88-01-02 L
is cited in section B of this report as a result of PDT's. failure-to properly test these particular overloads and to develop proper acceptance criteria.-
