RTP per Load Dispatcher request due to minimum generation l

requirements.

Narrative Summarv of Operatina Exneriences Limerick Unit 2 began the month of August-at a nominal 100%

of Rated Thermal Power (RTP).

Power was reduced a number of times during the month of August as a result of high turbine backpressure.

On August 7, 1994, at 0500 hours0.00579 days <br />0.139 hours <br />8.267196e-4 weeks <br />1.9025e-4 months <br />, power was reduced to 90%

RTP for a control rod pattern adjustment.

Power was restored to 100% RTP at 0839 hours0.00971 days <br />0.233 hours <br />0.00139 weeks <br />3.192395e-4 months <br />.

On August 13, 1994, at.1814 hours0.021 days <br />0.504 hours <br />0.003 weeks <br />6.90227e-4 months <br />, power.was reduced to 97%

RTP per procedure as a result of an unexpected increase in power.

The power increase was the result of a 500 Kv transmission line trip during a storm which caused a slight increase to the 2A Recirculation Pump.

Power was restored to 100% RTP shortly thereafter.

On August 21, 1994, at 0852 hours0.00986 days <br />0.237 hours <br />0.00141 weeks <br />3.24186e-4 months <br />, power was reduced to 92%

On August 24, 1994, the unit entered end-of-cycle coastdown.
