SUMMARY
OF OPERATING EXPERIENCE February 1996 The unit began the month at 100% power (860 MWe).
Power was reduced to 30% at 1800 on 02/12/96 to allow scheduled maintenace to be performed on the Main Generator stator liquid cooling system strainer. The strainer element was replaced and power was restored to 100% at 0145 on 02/13/%.
The unit continued to operate at 100% power (860 MWe) for the remainder of the month.

3 318/96-001 N/A N/A The unit tripped on 02/27/% at 1708 due to a partial loss of off site power. A switch yard relay malfunction that occurred earlier in the day, resulted in two switchyard breakers opening. These breakers being open did not adversely impact the plant, however during troubleshooting, additional switchyard breakers were opened which disconnected the unit from the 500 KV clectrical transmission system. The unit automatically tripped, all related safety systems functioned as required.
Power to all plant senice busses was restored at 2015.
A leak was discovered on the surface blow down line for 21 Steam Generator. Plant cooldown was initiated to facilitate the required repairs. Interim compensatory actions have been put in place that will require future switchyurd troubleshooting to be performed in accordance with plant procedures and require plant formal concurrence. The plant was placed in cold shutdouTi on 02/29/96 at 1430 and was shutdown for the remainder of the month.

4 DOCKET NO. 50-318 CALVERT CLIFFS - UNIT 2 March 15,1996
SUMMARY
OF OPERATING EXPERIENCE February 1996 The unit began the month at 100% power (860 MWe). On 02/27/96 at 1708 an automatic reactor trip occurred due to a partial loss of off site power.. A root cause analysis revealed that earlier on the day of the trip, a switchyard relay had malfunctioned. This opened two switchyard breakers but did not adversely impact the plant. Subsequent trouble shooting, however caused the inadvertent opening of additional switchyard breakers which disconnected the unit from the 500 KV electrical transmission system, causing the unit to automatically trip. All required safety systems functioned as required.
Power to the normal plant service busses was restored at 2015. During this shutdown period a leak was discovered on 21 Steam Generator surface blowdown line. The decision to cooldown was made to allow repairs. The unit was placed in cold shutdown (Mode 5) on 02/29/96 at 1430.
The unit remained in cold shutdown (Mode 5) for the remainder of the month.
