4 OPERATIONS NARRATIVE November 1980 The plant operated at steady state power through the 14th. During surveillance test of the APRM trip settings, operators improperly i tripped both Reactor Protection System trip channels causing a reactor scram on the 15th. A malfunction in the Turbine Control System allowed the main steam bypass valves to open causing a rapid vessel depressur-ization and couldown of the vessel. A bad turbine control computer circuit board was replaced to correct the malfunction in the Turbine Control System. A maintenance outage scheduled for the 20th was taken at this time to repair steam leaks on the turbine and perform various maintenance activities. The reactor was started up on the 20th and the generator was synchron-ized to the grid at midnight. The reactor operated at steady state conditions until the 29th. Power was reduced to adjust the control rod pattern and the reactor was returned to normal power operation. 1 - ) i 4 i t l l 9 t t}}
