SUMMARY

OF OPERATING EXPERIENCE I

March 1997 The unit began the month at 90% power as part of a gradual planned reduction in power (fuel coastdown),

in preparation for the refueling outage.

Power was slowly reduced to 82% by 03/13/97 at 1800. .

t l On 03/14/97 at 2058 power was reduced to support removing the Main Generator from the grid. The Main  ;

l generator was removed from the grid and the Refueling Outage commenced on 03/15/97 at 0016.  ;

The reactor coolant system was placed in a reduced inventory status on 03/22/97 at 1125 to support the planned Steam Generator Inspections. On 03/23/97 the unit entered mode 6, refueling with the reactor vessel head detensioned. The reactor coolant system exited the reduced inventory status on 03/23/97 at 2045.

The following significant work was completed or in progress during the month: l t - - Reactor Vessel Refueling.

l

\

- Steam Generator eddy current testing.

The unit was in mode 6 (refueling) for the remainder month.
