SUMMARY

OF MONTHLY OPERATING EXPERIENCE UNIT 1 s

JULY 1995 July 1 The Unit operated at a nominal value of 100% output.

through July 5 July 6 The Unit continued to operate at a nominal value of 100% output until 1030 hours0.0119 days <br />0.286 hours <br />0.0017 weeks <br />3.91915e-4 months <br /> when output was reduced to approximately 98%

to support o-ring replacement on the #1 and #2 Main Turbine Throttle Valves and Governor Valves.

Following o-ring replacement, output was returned to a nominal value of 100% at 1130 hours0.0131 days <br />0.314 hours <br />0.00187 weeks <br />4.29965e-4 months <br />.

July 14 With unusually warm atmospheric conditions present, incremental load reductions to a minimum output of approximately 94% were commenced at 1509 hours0.0175 days <br />0.419 hours <br />0.0025 weeks <br />5.741745e-4 months <br /> to stabilize condenser hotwell conditions.

July 15 Once conditions in the condenser hotwell began to improve, output was incrementally increased to a maximum output of aparoximately 97%. With continuing warm atmospheric conditions sti.1 present later in the day, incremental load reductions to g a mimmum output of approximately 92% were commenced at 1140 hours0.0132 days <br />0.317 hours <br />0.00188 weeks <br />4.3377e-4 months <br /> to stabilize condenser hotwell conditions.

Once conditions in the condenser hotwell had improved, the Unit was returned to full power at 2400 hours0.0278 days <br />0.667 hours <br />0.00397 weeks <br />9.132e-4 months <br />.

July 16 The Unit operated at a nominal value of 100% output for the through remainder of the report period.
