Dear Dr. Wolfe:
g 4
This letter addresses the inspection of your facility at San Jose, California conducted by Messrs. Richard P. McIntyre, Kamalakar R. Naidu, Stephen D.
Alexander, and Stewart L. Magruder of the Vendor Inspection Branch cn April 23 through 26,1990, and the discussion of our findings with Mr. James J. Fox and other members of your staff at the conclusion of the inspection.

--The ins ection was conducted to: (1)reviewGENuclearEnergy's(GENE) response
-and imp ementation of. corrective actions to previously identified nonconfor-mances; (2) review the GENE. vendor audit program; (3) review of-GENE control of ~
quality activities at Service Centers and Product Departments; and (4) follow-
. W' up,on specific technical issues at operating reactors relating to BWR systems L d:
ard components.
L hb
~ Durirg.the inspection, it was found that the implementation of your Quality
%'d Assurance program failed to meet certain NRC requirements, specifically
. relating to the qualification of ' safety-related MSIV pneumatic manifold I.
6 semblies, including conformance to the applicable design and material i
specifications. This deficiency is a result of your failure to adequately.
l control quality activities of your vendors and subvendors, such as Automatic
,' ? -
Valve Corporation and the Ralph A. Hiller Company. GENE also failed'to conduct triennial audits of safetyrrelated vendors holding ASME. stamps and j
mW certificates, or at least verify control of their quality activities through b
documentation of surveillance or source inspection activities at these vendors.
s Also, examples were identified where GENE failed to conduct adequate audits of L
safety-related vendors. GENE failed to identify the results of Potential i:
Reportable Condition (PRC) 84-03 evaluation as a Germane-to-Safety Condition L
-and thus failed to notify all BWR owners of a potential problem with the Type 1
, CR2940' three position key lock switch,145C3040 Part 022. Lastly, GENE failed to fully implement the corrective actions committed to in response to' Nonconformance 89-01-02, Part A, concerning the dedication of molded case circuit breakers.

c Dr. Bertres Wolfe-
-2 August 3, 1990 We acknowledge the receipt of your letter dated May 10, 1990, in response to our' letter frem Mr. Brian K. Grimes to Robert C. Mitchell, dated April 20, 1990, in which you describe the results of your reinspection of the failed GE AK 2A-50 circuit breaker and other AK circuit breakers refurbished by GE at the Pilgrim Nuclear Power Station. This reinspection concluded that none of the refurbished circuit breakers were'in danger of failure to operate due to
' variations in hardware configurations, and that all of Pilgrim circuit breakers refurbished by GE in 1987 with missing and misaligned parts were fully l
functional (exceptfornormalwear). To address NRC concerns on the generic implications of these breaker failures, GENE stated that evaluation has discovered no generic implication for GE manufacture or refurbishment for the circuit breaker. failure at Pilgrim.
We have reviewed the GE reinspection data for the Pilgrim circuit breakers, and the bent snap ring and broken prop reset spring issues involving 4.16.kV circuit breakers, as discussed in section E.9 of the inspection report (andinNRCInformationNo.9041: Potential Failure of General Electric i
Magne-Blast Circuit Breakers and AK Circuit Breakers).
As a result, we
~
4 continue to have concerns related to GENE's control of quality activities conducted by nuclear service centers and product departments. We will continue to monitor this area through inspection activities and followup of specific l.
hardware issues.
In response to the enclosed Notice of Nonconformance, please provide us within 30 days from the date of this letter, a written statement containing: (1)a i
L description of the steps that have been.or will be taken to correct these items; (2) a description of the steps that have been or will be taken to prevent recurrence; and (3) the dates that your corrective action and preven-j
.tive measures were or will be completed. We will consider extending the q
response time if you can show good cause for us to do so.
i The responses requested by this letter are not subject to the clearance procedures of the.0ffice of Management and Budget as required by the Paperwork Reduction Act of 1980, PL 96-511.
In accordance with 10 CFR 2.790 of the Commission's regulations, a copy of the l
I letter and the enclosed inspection' report will be placed in the NRC's Public l-Document Room. Should you have any questions concerning the inspection, we l
would be pleased to discuss them with-you.
