SUMMARY

OF OPERATING EXPERIENCES L .aerick Unit 2 began the month of June at 100% of rated thermal power. On i'desday, June 2, reactor power was reduced to 68% to support repair of the '2A' _ Condensate Pump which had been exhibiting hi ' vibration. Early on Wednesday, June 3, reactor power was returned to 100% of rated thermal power. On Wednesday, June 17, reactor power was briefly reduced to 95%

of rated thermal power for a control rod pattern adjustment.

Unit 2-ended this operating period at 100% of rated thermal power.

Operational events that occurred during the mc.ath of June include:

The ' 2A' and ' 2B' Residual Heat Removal (RHR) suppr3ssion pool cooling line flow orifices were renoved to ensure compliance with the Technical Specification requirement for heat exchanger flow due to diagnostically identified leakage a through the respective RHR heat exchanger bypass valves.

Respective surveillance requirements have been verified.

-At 2031 hou.rs on Sunday, June 21, during performance of an +

'0A' Standby Gas Treatment System (STGS)/ Reactor Enclosure Recirculation Syste.m (RERS) monthly flow surveillance test, an actuation of a~ Reactor Enclosure Blowout (Relief) panel occurred. The respective panel was successfully reinstalled at 2116 hours0.0245 days <br />0.588 hours <br />0.0035 weeks <br />8.05138e-4 months <br />. Secondary containment was declared operable at 2350 hours0.0272 days <br />0.653 hours <br />0.00389 weeks <br />8.94175e-4 months <br /> following maintenance rework. A four hour notification was made to the NRC pursuant to ICCFR50.72 (b) (2) (iii) (c) .
