Docket No. 50-352 Attachment to Monthly Operating Report for August 1997 Limerick Generating Station Unit 1 August 1 through August 31,1997 1.

Narrative Summary of Operating Exoeriences Unit 1 began the month of August 1997 at a nominal 100% of rated thermal power (RTP).

On August 1,1997 at 2121 hours0.0245 days 0.589 hours 0.00351 weeks 8.070405e-4 months , power was reduced to 98% of RTP for main turbine valve testing. Power was restored to 100% RTP at 2229 hours0.0258 days 0.619 hours 0.00369 weeks 8.481345e-4 months .

On August 8,1997 at 1600 hours0.0185 days 0.444 hours 0.00265 weeks 6.088e-4 months , power was reduced to 98% of RTP for main turbine valve testing. Power was restored to 100% RTP at 1642 hours0.019 days 0.456 hours 0.00271 weeks 6.24781e-4 months .

On August 16,1997 at 1600 hours0.0185 days 0.444 hours 0.00265 weeks 6.088e-4 months , power was reduced to 96% of RTP because of elevated turbine condenser back-pressure. While at reduced load, scheduled main turbine valve testing was performed. Power was further reduced to 90% of RTP at 2235 to perform scheduled rod pattern adjustment. Power was restored to 100% RTP on August 17, at 0640 hours0.00741 days 0.178 hours 0.00106 weeks 2.4352e-4 months .

I On August 23,1997 at 2230 hours0.0258 days 0.619 hours 0.00369 weeks 8.48515e-4 months , power was reduced to 98% of RTP for main turbine valve testing. Power was restored to 100% RTP at 2330 hours0.027 days 0.647 hours 0.00385 weeks 8.86565e-4 months .

On August 30,1997 at 2103 hours0.0243 days 0.584 hours 0.00348 weeks 8.001915e-4 months , power was reduced to 98% of RTP for main turbine valve testing. Power was restoteu to 100% RTP at 2200 hours0.0255 days 0.611 hours 0.00364 weeks 8.371e-4 months .

On August 31,1997 at 1059 hours0.0123 days 0.294 hours 0.00175 weeks 4.029495e-4 months , power was reduced to 59% of RTP. This was an administrative response to an uncoupled control rod that was discovered during a rod exercise test. Power was restored to 100% RTP at 2359 hours0.0273 days 0.655 hours 0.0039 weeks 8.975995e-4 months after the control rod was inserted and disarmed.

Unit 1 ended this month operating at 100% RTP.
