SUMMARY

OF OPERATING EXPERIENCE MONTH: MARCH 1998 During the month of March, Unit 1 was base loaded.

There was one power reduction and there were no shutdowns.

On the 15th at 0100 the Unit started to ramp down in power for a Turbine Valve testing. At 0325 tne Unit halted the power decline and started the testing. At 0439 the Unit started to ramp up and at 0800 the Unit returned to full power operation.

l Because of the LP rotor upgrade the Unit is producing additional megawatts. The values for the Designed Electrical Rating and Maximum Dependable Capacity (both gross and net) will be changed after the Unit completes an URGE test.
