Narrative Summary of Operating Experiences I

i I

On February 1, 1986 at 0001 hours1.157407e-5 days 2.777778e-4 hours 1.653439e-6 weeks 3.805e-7 months , Limerick Generating Station Unit 1 was declared to be in commercial operation

,j with a net capacity of 1055 MWe.

On February 10, 1986 at 1430 hours0.0166 days 0.397 hours 0.00236 weeks 5.44115e-4 months , with the unit at 99.8%

I 1

rated power, a full reactor scram occurred as a result of high neutron flux (flow biased).

The neutron flux spike was the result of an increase in reactor pressure which was i

caused by the unexpected closure of the Turbine Control jj Valves.

A ground in the Electrohydraulic Control (EHC) circuit caused.the Turbine Control valves to close.

The cause of the ground is unknown, but suspected to have resulted from testing activity which involved temporarily connecting a digital-voltmeter in the circuit to monitor EHC signals.

Reactor startup was begun the same day, the turbine-generator was synchronized at 1655 hours0.0192 days 0.46 hours 0.00274 weeks 6.297275e-4 months on February 11, 1986 and 100% rated power operation was achieved on February 12, 1986.

1 The unit ended the report period operating at 100% rated power.

Challenges to Relief Valves il

}

During this month, there were no challenges to the main steam system safety-relief valves.
