1. NARRATIVE

SUMMARY

OF OPERATING EXPERIENCES Limerick Unit 1 began the month of July at a nominal 100% of rated thormal power. On July 7, 8,13,17, and 18 power was reduced to 98-99% due to high turbine back pressure. On July 19, load was reduced to 87% because of '1H' condensate domineralizer regonoration. Reactor pomor was returned to 100% on the fo!!owing shift. A series of load drops to 94% were done due to high turbine back pressure and then a load drop to 86% for '1D* and 'IG' condensate filtor domineralizor regonoration was conducted. Reactor power was returnod to 100% on July 21.

Load drops of 6% 3%. air) 8% were conducted on July 21, 22, and 23 due to high turbine back pressure. On July 23 at 2343 hours0.0271 days <br />0.651 hours <br />0.00387 weeks <br />8.915115e-4 months <br />, with the reactor ht 100% power a '1B' reactor recirculation pump trip caused a power reduction to 35%. Reactor power was returned to 95%

on July 26, but a load drop to 60% was done for a 100% control rod pattern adjustment.

Reactor power was returnod to 100% on July 28. A brief load drop to 96% was performed for a control rod exercise test on July 28. On July 31, load drop to 90% to perform a control rod pattern adjustment was conducted. Unit 1 ended the month of July at 100% of rated thermal power.

Operational events that occurrod during the month of July included:

On July 24, the '1B' Reactor Recirculation Pump Drive Motor Breaker trippod. Roactor power was roduced to approximately 30%. The Reactor Rocirculation Pump tripped due .

to spurious actuation of the pump motor stator high temperature relay. This condition

. was reset and tho '1B' Reactor Rocirculation Pump was restarted.

11. Challences to Maln Steam Safety Relief Va!ves There were no challengos to the Main Steam Safety Roliof Valves during the month of July.
