NIAGARA HOHAQK POWER CORPORATION NINE HILE POINT NUCLEAR STATION UNIT f2 NARRATIVE OF OPERATING EXPERIENCE Nine Mile Point Unit 2 entered the final Power Ascension Testing Condition (TC-6) during the month of February 1988.

Host of TC-6 testing was completed.

Tests included Recirc System and Feedwater System testing, LPRM/APRM calibration and MSIV full isolation.

During the MSIV isolation 2

SRVs were challenged automatically five (5) times.

These 2

SRVs plus three (3) others were opened manually later in the event to control pressure.

RCIC System was also initiated manually to aid in pressure control.

The completion of TC-6 and warranty run and the declaration of Commercial Operation are expected in March.
