SUMMARY

OF OPERATING EXPERIENCE February 1994 l The unit began the month shutdown in mode 3 due to a unit trip occurring late January due to a lor,s of the 120 Vac Vital Panel 1YO2. The unit was returned to power and paralleled to the grid on 2/2/94 at 1048.

On 2/8/94 at 1942 the unit commenced shutting down for a planned refueling outage. The unit was removed from the grid at 0206 on 2/9/94. The unit ended the month shutdown and defueled in mode

POCNET NO. 50-318 CALVERT CLIFFS - UNIT 2 March 15,1994

SUMMARY

OFOPERATING EXPERIENCE February 1994 The unit began the month at 100% reactor power (865 MWe).

, On 2/20S4 at 0015 while a Surveillance Test was being performed on the Control Element Assembly (CEA), one CEA dropped causin;; the power to decrease to approximately 97?o. The problem was corrected and the power was restored to 100fc at 0420. ,

On 2/26/94 at 0200 power was reduced to approximately 750 MWe for Main Turbine Valve testing, e Water Box cleaning, Data Acquisition System (DAS) repairs and repair of the Intercept and Reheat Valves. Power was further reduced during the maintenance to approximately 76% to repair the 25A Feedwater Ileater Tube Side Relief Valve (2-RV-1427) which was lifting due to a broken f.,nring.

s. The relief valve was repaired and the power was restored to 100Tc at 09(H)on 2/27/94. The unit remained at 100% power (870 MWe) for the remainder of the month.
