Docket No. 50-352 Attachment to Monthly Operating Report for January 1996 Limerick Generating Station Unit 1 January 1 through January 31,1996 1.

Narrative Summarv of Ooeratina Exoeriences Unit 1 began the month of January at a nominal 100% of rated thermal power (RTP).

On January 2,1996 at 2310 hours0.0267 days <br />0.642 hours <br />0.00382 weeks <br />8.78955e-4 months <br />, power was reduced to 84% RTP to remove the B Reactor Feedwater pump from service for planned maintenance. Power was increased to 90% RTP at 0310 hours0.00359 days <br />0.0861 hours <br />5.125661e-4 weeks <br />1.17955e-4 months <br /> on January 3,1996, following removing pump from service.

Power remained at 90% RTP for planned maintenance on the A Reactor Feedwater pump until power was reduced below 90% RTP due to end of cycle coastdown.
