I. NARRATIVE

SUMMARY

OF OPERATING EXPERIENCES Limerick Unit 1 was in the fourth refuel entage throughout the

', month. On Friday, April 10, Unit 1 reactor core offload was completed to support shuffling of control rod blades, HCU and CRD maintenance,- replacement of all LPRM strings and maintenance and testing on Emergency Core Cooling Systems. On Tuesday, April 28, Unit l entered OPCON 5 and began reactor

~

core' reload. Unit i ended this reporting period on day 42 of the Refueling Outage with reactor core reload in progress.

Operational events that- occurred during the month of April

-included:

The 'B' ESW loop war.i%.clared Inoperable to support isolntion

  • - valve installation ca the 'B' loop ESW piping in the Unit 1 HPCI room. Unon completion of valve installation and testing on Monday,-April 27-(54 hours6.25e-4 days <br />0.015 hours <br />8.928571e-5 weeks <br />2.0547e-5 months <br /> and 55 minutes had elapsed) 'B'

SUMMARY

OF OPERATING EXPERIENCES Limerick Unit 2 began the month of April at a nominal 100% of rated thermal power. On Wednesday, April 8, reactor power was briefly reduced to 90% to support a control rod pattern adjustment. and Main' Turbine cor. trol v?lve testing. On

Saturday April 25, reactor power was reduced to 95% to support isolation of a condenser waterbox because of a leaking condenser tube. On Sunday April 26, reactor power was returned to 100% of rated ther1 cal power - adequate condensor vacuum was able to be maintained with one waterbox isolated.

On Thursday April 30, reactor power was reduced to 98% of rated thermal power due_to increasing turbine-back pressure due to isolation of a mtin condenser waterbox. Unit 2 ended this operating period at 9G% of rated thermal power.

Operatfonal events that occurred during the month of April includad:

The 'B' ESW loop was declared Inoperable to support isolation valve-installation ot the 'B' loop _ESW piping in the Unit.1 HPCI room. A.one time revision'to the ESW system Technical Specifications ullowed a 72 hour8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br /> relief-frcm the ESW system Technical-Specification 3 0.3 required shutdown with the 'B' loop of ESW inoperable. Upon completion of valve installation and Lasting on Monday, April 27 (54 hwrs and 55 minutes had elapsed) 'B' ESW was declared operah e.
