Power was restored to 100% RTP at 1730 hours0.02 days <br />0.481 hours <br />0.00286 weeks <br />6.58265e-4 months <br />.

On June 19,1996, at 1630 hours0.0189 days <br />0.453 hours <br />0.0027 weeks <br />6.20215e-4 months <br />, power was reduced to 98% RTP due to high turbine backpressure. Power was restored to 100% RTP at 2212 hours0.0256 days <br />0.614 hours <br />0.00366 weeks <br />8.41666e-4 months <br /> On June 20,1996, at 1200 hours0.0139 days <br />0.333 hours <br />0.00198 weeks <br />4.566e-4 months <br />, power was reduced due to high turbine backpressure Power was reduced to 94% RTP.

overcurrent. This resulted in a decrease in condenser vacuum. Power was reduced to 96 %

RTP in order to recover condenser vacuum. Power was restorad to 100% RTP on June 23, 1996, at 0000 hourt. ,

Unit 1 ended this operating period at 100% of RTP.
