6 OPERATIONAL

SUMMARY

MARCH 1995 i

e UNIT 1 [

Unit 1 generated 718,250 megawatthours (MWh) (gross) electrical' power-during March with a capacity factor of 83.9 percent.

Unit i remained in Mode 4 at the beginning of March'as inspections .

continued on reactor vessel' level indicating system (RVLIS) compression fittings following a reactor coolant system leak at a_ compression fitting.

on a RVLIS line in the incore instrument room. The Unit 1 reactor was taken critical on March 3 at 2250 Eastern standard time (EST). Unit 1 was tiedLto.the grid at 1259 EST on March 4. Unit 1 reached 100 percent

-reactor power on March--14.

Unit 1 operated at near 100 percent reactor. power through the end of ,

March.

UNIT 2 Unit 2 generated 860,910.megawatthours (MWh) (gross) electrical power during March with a capacity factor of 101 percent. -
