PURPOSE

1.1 Objective

To provide the steps necessa,y to test the tripping ability of molded case circuit breakers and motor circuit protectors. In field testing it is not pmetical to meet laboratory conditions and is therefore.not intended to determine whether the circuit breaker exactly meets the manufacturer's published curves. L

1.2 Applicability

1 . Applies to all molded case circuit breakers and motor circuit protectors.

SUMMARY

OF CHANGES STEP CHANGE REASON Section 3 Removed "Not DC Rated" statement. Breakers may be DCrated even if not Attach.12.2&3 so stated on the time current curves. 3.43 Add NEMA AB 1(1986) Used as a Reference. 6.1.2 Add instruction to sign verification. Clarification of the requirement. Sections 6.4, Added new sections for selecting test Makes the difference between types 6.5, 6.6. 6.7 values and recording data. more clear. Section 6.8 Revised short. time test specifying .To be in line with NEMA AB 1(1986) current limits and time limits. Section 6.7 Changed acceptance criteria to 0.1 sec. This time is more in line with the [ Seetion 8.0 definition ofinstantaneous (no intentional delay) Step 8.3 Revised acceptance criteria. IN line with NEMA AB.2(1986) Section 8.0 Changed Instantaneous test current In line with NEMA STD AB 2 (1984) Att.12.2&3 limits.

These items wert identified in a list of potentially defective equipment in the subject Information Notice and its Supplement

One, A compthensive review of all available documentation was undertaken to determine their location. This search consisted of a review of records from the warehouse, recei at inspection and Nuclear Records groups. No record of where this equipment is locatec has been found. A manual search of all available Material Issue Forms (MIF's) also -

could not close out this issue. Although one item was identified on the MIF's, the follow-up investigation of the Autornated Work Order showed that the equipment was 1 not installed in this QA application. It is felt that although the search could not locate these items,it definitively proves that - this equipment is not being used in a safety related application.

SUBJECT NOA 9684Ah]Qf'IN 88-46: Reoort of Defective Refurbished Circuit Breakers The purpose of tnis documem > record the results of our evaluation of the subject NOA. The subject notice and its supplement one (1) was issued to alert the industry that defective, refurbished electrical eqmpment (circuit breakers) may have been supplied to plants as new equipment. A review of our purchasing reconis back to 1985 indicates that no new equipment listed in IN 88-46 Attachment 2 was bought by suppliers listed in IN 88-46 Attachment 1. This review was completed by checking if stock code numbers exist for the items listed on Attach.-2 and, if so, to scan all applicable purchase orders to see who supplied the item; Utilizing this process, some listed items were identified with stock code numben although none of these items were bought from the list of suspect suppliers (Attach.1). Although the above review revealed no new problems, the IN 88-46 supplement one - document speci5cally referenced Connecticut Yankee as having received electrical materials (via a local distributor) from one of the five suspect suppliers presently under L review by the NRC. The associated pmchase orders have been reviewed and an NCR (RC-88-166) was issued to hold all referenced equipment (total of 45 items) in the CY warehouse until this issue can be resolved. However, six items ( 5 reversing starters and 1 overload relay) were drawn from the warehouse before the NCR was issued. Presently, our research shows that the equipment drawn from stock was used for a non-category I function, but this must be confirmed before drawing this conclusion. I l Finally, a review of our station circuit breaker testing procedures was done to see if they could identify defective breakers before they are placed in service. Prior to installation, a bench test is performed on molded case circuit breakers which verifies that the breaker trips during a xedetermined range of time when a given quaniity of current is passed through it. T1is test is repeated for each one of the three phases of the breaker. In addition, a meggar test is performed with the breaker open, and then closed, i to provide some assumnce that the insulating characteristics are acceptable. 'Ihese l parameters are also verified prior to placing metal-clad switchgear in service. Successful performance of twe tests provides a measure of confidence in the breakers functional characteristics before they are subjected to functional testing.

Purpose:

This information' notice supplement is being provided to present additional information regarding.the supp y of surplus or refurbished electrical equip-ment such as circuit breakers CBs)tonuclearpowerplantsasdiscussedin ' NRC Information Notice (IN) No 88-46 including Supplement 1. It is expected that recipients will review this information for applicability to their fact-11 ties. However, suggestions contained in this information notice do not constitute NRC requirements; therefore, no specific ection or written response is required.- Description of Circumstances: l 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. L 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 b distributors of electrical equipment. This information is summarized in Attac nt 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 L assure breaker functionality and quality, l' i 1 8122800 6
