82-15 (A) (1) At 1800 on September 21, 1982 with the unit at 100% power a rampdown to Generator off line was commenced. The Generator was taken off line and Control Banks driven to zero steps.

The reactor was suberitical and maintained in Mode 3 (Hot Standby). Feed Pump Recire Valve 2-FW-250C required repair due to an excessive leak. In order to isolate and repair no recirc path would be available for the Main Feed Pumps.

The unit was brought off line and the repairs made in approximately 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />, at which time the unit was returned to power (Generator on line) at 0333 on September 23, 1982.

82-16 (A) (5) At 2015 on September 27, 1982 commenced power reduction to 32 percent power to allow repair of "B" feedwater control valve.

Bypass feedwater control valves were used while repairs were made to normal feedwater control valve pneumatic control system.

Repairs were successful and unit was returned to power, reaching 100 percent at 0300 on September 28, 1982.
