experiences for this month which required load reductions or resulted in 'l significant non-load related incidents.

Date Time Data February 01, 1997 0000 Began month with unit at 100% power, 950 MWe.

February 08, 1997 2026 Placed steam dump system in Steam Pressure mode l for a partial calibration of Main Steam '

Temperature T-1408.

2102 Control Room received Main Steam Line- High Flow annunciation. A walkdown of the control board revealed: steam flow increase, Tave/ Tref decrease, MW generated decrease, and control rod "D" bank insertion of 223/224. All indications consistent with'a momentary opening of steam dump valves. This observation was  ;

supported by the Turbine Building Operator who 1 identified a brief flow noise in the area.

Instrument Technicians were instructed to stop work in the racks for investigation.

)

2115 Control rods restored to full out position of )

225 steps.

February 09, 1997 0040 Determined the momentary partial opening of the steam dumps was caused by a procedural _ error.

The calibration procedure required the dumps to be in Steam Pressure mode versus the correct mode to be OFF for the test.  :

February 21, 1997 0940 Commenced ramp down for performance of Turbine Valve Freedom Test .(TVFT) from 100% power, 950 MWe.

1025 Unit stable at 92% power, 875 MWe for TVFT.

1125 TVFT complete satisfactorily.

1128 Commence ramp to 100% power.

1214 Unit stable at 100% power, 948 MWe.

February 28, 1997 2400 Ended month with unit stable at 100% power, 946 MWe.
