MR Number: 3-97-0066 Big Rock Point 1 Date: 04/29/97 Charlevoix,Michigan INSPECTOR AT SITE Dockets: 50-155 BWR/GE-1 Subject: FORCED OUTAGE CONTINUATION Discussion: On April 27, 1997, at 1:54 p.m., the reactor was taken critical following a week long outage to replace a seal on recirculation coolant pump (RCP) No. 2. On April 28, 1997, at 5:25 a.m., while attempting to close main generator breaker 116 OCB, the breaker reopened and would not stay latched closed. The licensee continued maintaining the turbine at 3600 RPM and dumping steam to the condenser through the by-pass valve and holding reactor power constant at about 22 percent while the cause of failure was being investigated. On 04/29/97, the licensee decided to shut down the plant and bring in a breaker specialist to assist in repairing the breaker. A startup date for the unit has not been determined. Regional Action: The SRI and a region project engineer monitored the plant startup and shutdown activities and will monitor breaker repairs. Contact: BRUCE BURGESS (630)829-9629 _
