SUMMARY
OF OPERATING EXPERIENCE FOR MAY 1986 The plant operated at approximately 97% power until May 19 at 1416 hours0.0164 days <br />0.393 hours <br />0.00234 weeks <br />5.38788e-4 months <br /> when the reactor tripped due to a complete loss of power to the turbine EHC Control System, resulting in Turbine Governor and intercept valves cidsing I
and subsequent Reactor trip on PCS High Pressure.
The reactor was again critical on May 20 at 0751 hours0.00869 days <br />0.209 hours <br />0.00124 weeks <br />2.857555e-4 months <br /> and remained in hot standby until May 21 at 2209 hours0.0256 days <br />0.614 hours <br />0.00365 weeks <br />8.405245e-4 months <br /> when the reactor returned to suberiticality and proceeded to cold shutdown for repairs. The Plant achieved cold shutdown on May 22 at 2159 hours0.025 days <br />0.6 hours <br />0.00357 weeks <br />8.214995e-4 months <br /> and remained there through the end of the reporting period.
