1. Name and address of the individual or individuals informing the Commission.

Dr. G. G. Sherwood Manager of Safety & Licensing Operation General Electric Co.

175 Curtner Ave., San Jose, CA 95125

2. Identification of the facility, the activity, or the basic component supplied for such facility or such activity within the United States which fails to comply or contains a defect.

Non-Safety grade Circuit Breaker (188C7837) incorrectly supplied for Class IE GE Electric Protection Assembly

3. Identification of the firm constructing the facility or supplying the basis component which fails to comply or contains a defect.

General Electric Company Nuclear Energy Business Operation 175 Curtner Avenue San Jose, California 95125

4. Nature of the defect or failure to comply and the safety hazard which is created or could be created by such defect or failure to comply.

GE supplied to Fitzpatrick Nuclear Station two non-safety grade circuit breakers (CB) without required trip coils for use in the safety related Electrical Protection Assemblies (EPA). These CBs have the same physical dimensions as the required safety related CBs and could easily be installed in the Class IE EPAs. The safety hazard is the potential inoperability of necessaryportionsoftheRPS,geutronMonitoringSystem(NMS)andNuclear Steam Supply Shutoff System (NS ) to generate Scram and Isolation safety actions. With one deficient circuit breaker installed in an EPA, a degraded RPS bus condition, and a single failure of the redundant EPA, the safety equipment connected to the bus may not function. It is this specific degraded bus condition that brought the NRC to require backfit-ting of the EPA devices to all BWR plants.

5. The date on which the information of such defect or failure to comply was obtained.

April 5, 1985.

6. In the case of a basic component which contains a defect or fails to comply, the number and location of all such components in use at, supplied for, or being supplied for one or more facilities or activities subject to the regulations in this part.

Only two incorrect circuit breakers were supplied to Fitzpartick Nuclear Station.
