Finding

Title

Technical Support Center Diesel Fails To Load

Description

On March 10, 2011, the licensee inadvertently opened a switchyard breaker that was providing power to various non-safeguards busses, as well as, bus 6, a 4160-volt safeguards bus. The TSC diesel automatically started as expected, however, the output breaker failed to close and power bus 46, as designed. The licensees troubleshooting and investigation determined that the TSC output breaker failed to close because of a failed breaker latching relay. The licensee replaced the relay and restored the TSC diesel to functional status. The licensees apparent cause evaluation was still in progress at the conclusion of the inspection period, and the inspectors did not have enough information to determine if a performance deficiency existed. Pending further review and inspection, this issue was considered a URI (URI 05000305/2011002-05, Technical Support Center Diesel Fails To Load).
