NARRATIVE

SUMMARY

OF OPERATING EXPERIENCES j

Limerick Unit 1 began the month of December at a nominal 100%

of rated thermal power.

On Sunday, December 6, reactor power

{

was reduced to 90% for control valve testing and restored the same day.

On Friday, December 11, a one hour report to the NRC was made for the loss of meteorological tower data and the loss of approximately 50% of the EPZ sirens due to adverse j

weather conditions. -on Saturday, December 12, reactor power j

was reduced to 44.3% to change out the Reactor Recirculation j

Pump Motor Generator set brushes; power was restored to 100%-

j on December 14.

On Thursday, December 31, per the load 4

dispatcher's request, power was reduced 100 MWe due to excess l

generating capacity.

Reactor power was restored to 100% of l

rated on the same day.

Unit 1 ended this cperating period at a nominal 100% of rated thermal power.

SUMMARY

OF OPERATING EXPERIENCES l

Limerick Unit 2 began-the month of December in end-of-cycle coastdown at a nominal 79% of-rated thermal power with core flow maximited.

On Friday, December 4,

both Recirculation l

Pumps tripped due to the End of Cycle / Recirculation Pump Trip j-Breaker Opening logic being initiated during performance of j

surveillance testing, a manual scram was initiated per plant i

procedures.

On

Sunday, December 13, post scram pcwer ascension was completed with reactor power at 80% rated 4

thermal power.

On Monday, December 28, load was reduced 100 i

MWe to perform control rod pattern adjustments, power was restored that same afternoon.

Unit 2 ended this operating i-period at a nominal 69% of rated thermal power, in end-of-cycle coastdown.
