- 3. Report Date: 13 February 1978
- 4. Occurrence Date: 22 January 1978
- 5. Identification of Occurrence:
The "A" control rod drive breaker failed to trip contrary to Table 3.3-1 of Technical Specificatisa 3.3.1.1.
- 6. Conditions Prior to Occurrence:
Made 3 hot standby operation.
- 7. Description of Occurrence:
Ac 0400, during the perfor: nance of the RPS Functional Test SP-110, in preparation for ,-
unic startup, the "A" control rod drive breaker failed to trip when a simulated trip .,
signal was- initiated. The electrical supervisor was notified. and naistanance Work RequesC- )
- 0-6041 was initiated. The "A" CRD breaker was renewed with a. replacement breaker and was tested satisfactorily in accordanca with Preventive Maintenance Procedure PM-ll8. l
- 8. Designation of Apparent Cause:
The cause of this evenn was due to the failure of the breaker undercurrent relay to function.
- 9. Analysis of Occurrence:
There were no safety 1:mplications as a result of this occurrence as redundant control rod drive breakers were available and verified operable.
- 10. Corrective Action:
Preventive Maintenance Procedure PM-118 was perfor:med en all CRD breakers with satisfacto: l results .
- 11. Failure Data: l This is the first occurrence of this event.
