SUMMARY

OF MONTHLY OPERATING EXPERIENCE - OCTOBER 1981 October 1 Station in Operational Mode 1 at nominti full power.

October 2 Station in Operational Mode 1 at neminal full power. At 2002 hours0.0232 days <br />0.556 hours <br />0.00331 weeks <br />7.61761e-4 months <br />, through commenced a load reduction to permit cleaning of the main condenser October 5 section B.

Load was stabilized at 45% power by 2144 hours0.0248 days <br />0.596 hours <br />0.00354 weeks <br />8.15792e-4 months <br />. The condenser was returned to service at approximately 2100 hours0.0243 days <br />0.583 hours <br />0.00347 weeks <br />7.9905e-4 months <br /> on October 4 and the station load was increased to 60% power by 2127 hours0.0246 days <br />0.591 hours <br />0.00352 weeks <br />8.093235e-4 months <br />.

The station followed system load requirements reaching nominal full power by 0650 hours0.00752 days <br />0.181 hours <br />0.00107 weeks <br />2.47325e-4 months <br />.

October 6 Station in Operational Mode 1 at nominal full power.

through October 8 October 9 Station in Operational Mode 1 at nominal full power.

Between 2040 through hours on October 9 and 0530 hours0.00613 days <br />0.147 hours <br />8.763227e-4 weeks <br />2.01665e-4 months <br /> on October 12 station load was reduced October 12 to 60% power because of low system load requirements and for fuel conservation. At 1217 hours0.0141 days <br />0.338 hours <br />0.00201 weeks <br />4.630685e-4 months <br /> on October 12 the Reactor tripped because of a dropped rod due to a blown stationary gripper coil fuse.

The Reactor was critical at 1533 hours0.0177 days <br />0.426 hours <br />0.00253 weeks <br />5.833065e-4 months <br /> and the unit was synchronized at 2054 hours0.0238 days <br />0.571 hours <br />0.0034 weeks <br />7.81547e-4 months <br />.

October 13 Station in Operational Mode 1 at 60% power.

Gradual increase of the station load was in progress, reaching nominal full power by 1600 hours0.0185 days <br />0.444 hours <br />0.00265 weeks <br />6.088e-4 months <br />.

October 14 Station in Operational Mode 1 at nominal full power.

through October 15 October 16 Station in Operational Mode 1 at nominal full power. Between 2200 hours0.0255 days <br />0.611 hours <br />0.00364 weeks <br />8.371e-4 months <br /> through of October 16 and 0900 hours0.0104 days <br />0.25 hours <br />0.00149 weeks <br />3.4245e-4 months <br /> of October 19, station load was reduced October 19 to 60% power due to low system requirements and for fuel conservation Station load was returned to 90% power.

October 20 Station in Operational Mode 1 at nominal 90% power for fuel conservation.
