SUBJECT:

P0TENTIALLY DEFECTIVE REFURBISHED CIRCUIT BREAKERS The enclosed Nuclear Regulatory Comission (NRC) Information Notice (IN) 88-46 describes the circumstances under which defective refurbished electrical equip-ment may have been supplied to nuclear power plants.

Our continuing investiga-tion of the five circuit breaker companies identified in the IN shows that the companies have shipped breakers to a number of government facilities and agencies.

Our review of a sample of invoices indicates that generally the breakers are sold to a distributor, and it was only the occasional shipment direct to the ena user that permitted us to identify the final government destination.

I have enclosed copies of invoices and orders that identify your agency as the customer. These documents represent our review of a selection af records spanning the last two or three years from all of the companies.

As other records are reviewed, we will provide any additional information that comes to light.

However, since some of the companies have been in business for as many as 30 years, a full historical records search will not be possible.

The five California companies appear to sell surplus new as well as refurbished breakers.

However, their refurbished equipment may be shipped in containers resembling original manufacturer containers.

If there is any additional information you require, please call me or Mr. Walter Haass at (301) 492-3219.

Sincerely, i

M. R an Brian K. Grimes, Director Division of Reactor Inspection and Safeguards Office of Nuclear Reactor Regulation

UNITED STATES NUCLEAR REGULATORY COMMISSION OFFICE OF NUCLEAR REACTOR REGULATION WASHINGTON, D.C.

20555 July 8, 1988 NRC INFORMATION NOTICE NO. 88-46:

LICENSEE REPORT OF DEFECTIVE REFURBISHED CIRCUIT BREAVERS Addressees:

All holders of operating licenses or construction pemits for nuclear power reactors.

Purpose:

This infomation notice is being provided to alert addressees of licensee reported information that defective refurbished electrical equipment, such as circuit breakers (CBs), may have been supplied to nuclear power plants.

it is expected that recipients will review this infomation 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:

Pacific Gas and Electric Compan purchase order for 30 new, non y (PG&E) has informed NRC that it placed a safety-related, molded-case, KHL 36125-type CBs manufactured by the Square D Company ISquare D) with a local electrical distributor.

These CBs were intended for use in non-safety-related applica-tions at PG&E's Diablo Canyon Nuclear Power Plant.

According to PG&E, the distributor in turn placed the order with a local sup-plier who bid the lowest price and promised the quickest delivery.

The CBs were delivered directly to the Diablo Canyon plant by the supplier; the dis-tributor did not have an opportunity to inspect the CBs.

Square D, aware of the purchase order, questioned its failure to receive an order for the unique vintage KHL 36125-type CBs.

With PG&E's pqrmission, Square D inspected the CBs and detemined that PG&E had been aivaa rsTurbished, rather than new, CBs.

Square D tested and performed detailed examinations of the CBs, and the results reported by PGtE follow.

A.

Physical Examination The yellow side labels used on the CBs were suspect in that the CB model numbers were typed on the labels whereas authentic labels are preprinted, 1

t The CBs departed from normal appearance in other respects as well.

J /)

IN 88-46 July 8, 1988 Page 2 of 3 The individual CB cases and each of the CB components appeared to be l

Square D products; however, the individual CBs incorporated components of different years of manufacture.

Each CB bore evidence of having been opened and reassembled.

R.

Electric Testing Square D subjected the CBs to five electrical tests.

None of the CBs complied with Square D or Underwriters' Laboratory (UL) specifications for all of the tests, and several of the CBs were out of tolerance on each of the tests.

At least four of the CBs failed to trip under circum-stances in which they are designed to trip.

Discussion:

1 In the past, there have been instances in which licensees purchased comercial-grade components, such as CBS, relays, trip units, and other electrical compo-i nents, from electrical distributors and have received components that did not meet the originai purchase order requirements.

NRC has received additional information indicating that the problem of surplus or defective refurbished CBs may also apply to CBs sold under other manufacturers' naines (e.g., General Electric, Westinghouse, ITE, Cutler Hamer, and Sylvania).

The electrical suppliers involved in refurbishing and sales of circuit breakers, including the Diablo Canyon, Square D circuit breakers, apparently include five California corporations.

These companies are (1) General Circuit Breaker &

Electric Supply, Inc., (2) HLC Electric Supply Co., Inc., (3) Pencon Inter-national, In., doing business as General Magnetics / Electric Wholesale, (4)

California Breskers, Inc., and (5) Anti-Theft Systens, Inc., doing business as ATS Circuit Breakers.nd as AC Circuit Breaker-Electrical Supply.

NRC has an investigation and vendor inspection in progress at the above compa-nies.

On the basis of the information developed to date, a preliminary list of customers of the five companies including a list of nuclear utilities (where available) is provided in Attachment 1.

equipment manufacturers whose names may have been used on surplus or re equipment sold as new equipment.

The information included in Attachments 1 and 2 is only prelininary and is provided to assist licensees in reviewing the potential of having procured suspect electr,ical equipment at their facilities.

Licensees are reminded of the requirements to ensure that orocured items meet the relevant specifications and codes and are suitable for the intended appli-cation.

Licensees should consider, as a matter of prudence, the need to inquire nf and to verify with their authorized distributors the sources of procured rnaterials, equipment, and components.

Licensees may meet these re

IN 88-46 July 8, 198P Page 3 of 3 NRC is gathering additional infonnation to detemine what further act'ons are neces s a ry.

The primary purpose of this information notice is to alert addressees of the situation as soon as possible.

~he NRC is considering issuing a bulletin to followup on this infomation notict when the NRC has sufficient information to define requirements.

No specific action or written response is required by this infomation notice.
