The pressure indicator isolation valve leaked through allowing control fluid to escape causing the turbine control valves to go fully closed.
The resulting rapid increase in steam generator pressure caused the steam generator water levels to shrink.
The reactor tripped on lo-lo steam generator levels causing the turbine trip.
The turbine control system and other equipment problems were repaired during the outage and the unit was returned to service at 2050 hours0.0237 days <br />0.569 hours <br />0.00339 weeks <br />7.80025e-4 months <br /> on 911120.
Reactor power reached 100% on 911123.
The unit exited the reporting period at 100% RTP.
There were no challenges to the pressurizer safety valves or power operated relief valves.
