Information Notice No. 91-48: False
Certificates of Conformance provided by Westinghouse Electric Supply
Company for Refurbished Commercial-Grade Circuit Breakers

Information Notice No. 91-48: FALSE CERTIFICATES OF CONFORMANCE
PROVIDED BY WESTINGHOUSE ELECTRIC SUPPLY
COMPANY FOR REFURBISHED COMMERCIAL-GRADE
CIRCUIT BREAKERS
Addressees:
All holders of operating licenses or construction permits for nuclear power
reactors.
Purpose:
This information notice is intended to alert licensees to problems in the
dedication for safety-related use of Westinghouse molded-case circuit
breakers (MCCBs) obtained from the Westinghouse Electric Supply Company
(WESCO) and supplied to the Peach Bottom Atomic Power Station (Peach Bottom)
by Spectrum Technologies USA, Incorporated (Spectrum). This information
notice is intended to alert licensees to the possibility that MCCBs
previously obtained from WESCO or Spectrum may have been unqualified and
subsequently dedicated for safety-related service without an adequate basis.
It is expected that recipients will review this information for
applicability to their facilities and consider actions, as appropriate, to
avoid similar problems. However, suggestions contained in this information
notice do not constitute NRC requirements; therefore, no specific action or
written response is required.
Description of Circumstances:
In April 1988, WESCO of Albany, New York, supplied 250 MCCBs to Spectrum of
Schenectady, New York. Spectrum dedicated these commercial-grade items on
the basis of independent testing and the certificates of conformance (CoCs)
it received from WESCO. During receipt inspection testing, Peach Bottom
determined that the MCCBs were not new and had been refurbished. The NRC
conducted an inspection and investigation of Spectrum and WESCO in 1988 and
1989. During these efforts, the NRC identified that the MCCBs provided to
Peach Bottom were reconditioned and not new equipment as specified in the
purchase order. Although the purchase order from Spectrum to WESCO
specifically required new equipment and CoCs, WESCO purchased the MCCBs from
a subvendor which dealt mainly in reconditioned equipment and provided these
reconditioned MCCBs to Spectrum with falsified CoCs that certified that they
were new equipment. In addition, the investigation identified that WESCO
ordered Westinghouse labels from the subvendor in order to label the
shipping boxes that lacked labels.

Spectrum performed the dedication inspection and testing to demonstrate the
adequacy of the MCCBs from WESCO. However, the validity of this testing
depended on the MCCBs being new equipment. Spectrum's failure to verify the
accuracy or the validity of the CoCs resulted in Spectrum accepting fraudu-
lent CoCs and providing reconditioned (as opposed to new) MCCBs to Peach
Bottom. The NRC concluded that the information that Spectrum provided
during discussions with NRC staff was not accurate or complete. Spectrum
has stated it misunderstood the NRC questions and did not intend to mislead
the NRC. However, the NRC concluded that the questions were simple and
clearly stated. Spectrum has, as part of their corrective actions, now
stated, under oath, that it will continue to provide accurate and complete
information to licencees and the Commission concerning the procurement and
dedication of components for use in nuclear power plants.
As part of Westinghouse's corrective action, Westinghouse has strengthened
its corporate policy to require that dedication services be performed under
the direction and supervision of the Energy Systems Business Unit and to
require notices on commercial-grade products to ensure that customers are
not misled in any way by the documentation for commercial-grade products.
In addition, WESCO will include notices in future proposals and product
literature stating that these products may not be suitable for use in
nuclear plants and that published information should not be relied upon as
the basis for dedicating commercial-grade products for use in nuclear
safety-related applications.
Discussion:
In Bulletin 88-10, "Nonconforming Molded-Case Circuit Breakers," the NRC
dis-cussed its concern that the reliability and capability of refurbished
MCCBs purchased as commercial-grade items for later upgrading to
safety-related applications may not meet the minimum commercial-grade
standards. In Bulletin 88-10, the NRC concluded that MCCBs that were
purchased from the circuit breaker manufacturer (CBM), or that can be traced
to the CBM, are of lesser concern than other MCCBs because circuit breakers
from the CBM, whether safety-related or commercial-grade, are manufactured
under controlled conditions to conform to a proven design. These controls
provide reasonable assurance that improperly refurbished components have not
been introduced and passed through the upgrading process.
In Bulletin 88-10, the NRC also requested that licensees provide reasonable
assurance that MCCBs purchased for use in safety-related applications
without verifiable traceability to the CBM will perform their safety
function. The bulletin defined verifiable traceability as required
documented evidence such as a CoC that established the traceability of
purchased equipment to the CBM. If the CoC was provided by any party other
than the CBM, the validity of the certificate was required to be verified by
the licensee or permit holder through an audit or other appropriate means.
This example of WESCO's past practice of repurchasing Westinghouse
components, some of which were used and refurbished, from outside sources
for resale in the commercial market underscores the importance of verifying
the traceability of equipment to the CBM. In addition, this example demon-
strates the importance of taking adequate measures to ensure the validity of
certifications that licensees and their vendors depend upon from commer-
cial-grade subvendors as a basis for dedicating equipment for safety-related
use.

The past actions of Westinghouse and Spectrum in this case indicate that the
previous licensee actions in response to Bulletin 88-10 may have been
inadequate if the licensee depended upon unverified certifications to
demonstrate the traceability of its MCCBs to the CBM. Although both
Westinghouse and Spectrum have implemented corrective actions to preclude
the recurrence of these events, licensees may wish to review their previous
procurements of MCCBs or other components, particularly those involving
WESCO or Spectrum, to confirm that the equipment is acceptable and that they
have verifiable traceability of the MCCBs to the CBM. In addition,
licensees may wish to examine the adequacy of any applicable audits and
their specific audit procedures to ensure that their vendors are adequately
verifying the validity of subvendor certifications. The NRC requires high
standards of quality for items supplied to licensees. To achieve this high
standard, the licensees and ultimately the NRC must depend to a large degree
upon the accuracy of the information provided to them by vendors and
indirectly by subvendors. Therefore, the NRC expects complete candor and
cooperation from the vendors that procure or supply safety-related equipment
for nuclear power plants.
