MONTHLY OPERATING ACTIVITIES MAY 1996 HIGHLIGHTS*

The unit entered this reporting period in Mode 5 at 0%

RTP for the Cycle 10 to 11 refueling/maintenance outage.

The Reactor was taken critical May 7 at 0701 for the first time in fuel cycle 11.

A Reactor trip occurred May 8 at 1044 during Main Turbine overspeed testing.

The automatic scram from 7%

RTP resulted when the anticipated trip of the Main Turbine was coincident with one channel of Main Turbine impulse pressure indicating greater than 10%.

The Main Turbine Generator was paralleled to the grid May 9 at 0732.

The Main Turbine Generator was removed from the grid May 10 at 1532 to facilitate Main Transformer phase one oil leak repairs.

Following the minor leak repair the Main Turbine Generator was paralleled to the grid May 11 at 0207.

The unit exited this reporting period in Mode 1 at 100%

RTP.

There were no challenges to the pressurizer safety valves or power operated relief valves.

Gross electrical generation for the month of May was 499410 MWH.
