SUMMARY

The plant operated at approximately 80% power for the period between 11/1/86 and 11/11/86 for fuel management considerations. Power was then increased to near 100% due to system demand until 11/17/86 when power was again reduced to approximately 80%. On 11/29/86 power was reduced below P-9 setpoint (50%) for 21 hours2.430556e-4 days <br />0.00583 hours <br />3.472222e-5 weeks <br />7.9905e-6 months <br /> to prevent an inadvertent turbine / reactor trip. Weekly turbine surveillance testing had resulted in an indeterminate position for the turbine limit switch and mechanical trip linkage.

PART B PORY AND SAFETY VALVE SUlttARY On 11/30/86, PORY 455A opened for approximately two seconds as the result of an inadvertent isolation of the plant instrument air system. The loss of instrument air resulted in a temporary loss of the pressurizer spray valves and letdown leading to the momentary system pressure increase above the PORV setpoint. Normal pressure and instrument air conditions were restored within six minutes.
