The operation of the pumps negated the necessity for motor rotation.
The motors were released to Power Production and are in service. The Control Rod Drive Cooling fans 2-MTRB-30-80B and 2-MTRB-30-88A are 75 horsepower motors which are excluded from the motor rotation program required by procedure P-6.
