Information Notice No. 88-46, SUPPLEMENT 2: LICENSEE REPORT OF DEFECTIVE
REFURBISHED CIRCUIT BREAKERS
Addressees:
All holders of operating licenses or construction permits for nuclear power
reactors.
Purpose:
This information notice supplement is being provided to present additional
information regarding the supply of surplus or refurbished electrical equip-
ment such as circuit breakers (CBs) to nuclear power plants as discussed in
NRC Information Notice (IN) No. 88-46 including Supplement 1. It is expected
that recipients will review this information for applicability to their faci-
lities. However, suggestions contained in this information notice do not
constitute NRC requirements; therefore, no specific action or written response
is required.
Description of Circumstances:
Information Notice No. 88-46 discussed a report by Pacific Gas and Electric
(PG&E) that defective refurbished CBs were supplied to PG&E's Diablo Canyon
Nuclear Power Plant by a California electrical supplier. Supplement No. 1 to
IN 88-46 provided a list of shipments of circuit breakers to nuclear power
plants or nuclear utilities by five California companies that may have
supplied defective refurbished electrical equipment.
The NRC has conducted followup inspections and investigations at selected CB
distributors and at companies suspected of selling used or refurbished circuit
breakers. Additionally, nuclear utility sales information related to poten-
tially refurbished CBs has been voluntarily provided to the NRC by
distributors of electrical equipment. This information is summarized in
Attachment 1. Sev-eral utilities identified in the Attachment have already
been contacted by the NRC concerning specific licensee procurements and
disposition of the equipment involved.
The NRC staff does not have any specific information on the condition of the
equipment provided by these companies; however, the activities observed at
some of the companies visited by the NRC were not considered sufficient to
assure breaker functionality and quality.
