Power was reduced slightly (97%) on 1 N493 at 2200 for Moderator Temperature Coefficient '. .

testing. The Unit was returned to 100% on 11/6N3 at 2000 after successful completion of the testing. j

( On 11/18S3 at 2227 power was again reduced to 77% reactor power to repair a failed R.elief Valve ]j (RV-1427) on 15A Feedwater Heater. The valve was overhauled and the unit was returned to 100% .

power on 11/20B3 at 1115. i i

The unit remained at 100% power and 860 MWe for the remainder of the month. - l l
