SUMMARY

The Unit began the month at full power. On 02/06/2004, the Unit was taken off line to perform planned maintenance on a Reactor Coolant Pump Motor. On 02/09/2004, the Unit was briefly tied to the grid when the Main Turbine Generator tripped on anti-motoring. The Unit was reconnected to the grid that same day and achieved full power 02/10/2004. From 02/24/2004 to 02/28/2004, Reactor power was allowed to drift down to -99.5% to replace resin in an RCS Letdown demineralizer.

The Unit operated the remainder of the month at full power.
