UNSCHEDULED SHUTDOWN GREATER THAN 48 HOURS                                               '
Carolina Power and Light (CP&L) has brought Brunswick Unit 1 to cold shutdown to repair a d: graded reactor recirculation pump seal. A six-day outage is expected.
CP&L decided to keep the unit out of service and make the repairs after the reactor scrammed from 100 percent power at 8:19 a.m. (EST) yesterday. The scram was triggered by a turbine trip caused by a spurious high reactor water level signal, which CP&L, is investigating.
Both the high pressure. coolant injection and reactor core isolation cooling systems initiated _to maintain reactor vessel water level after the scram. All engineered safe-           ,
guards systems functioned as designed.       Reactor pressure was controlled by the manual lifting of two relief valves.
Brunswick Unit 2 is shut down for refueling.
CP&L is prepared to respond to media inquiries.
The State of North Carolina has been informed.
This information is current as of 9:00 a.m. today.
