NIAGARA MOHAWK POWER CORPORATION NINE MILE POINT NUCLEAR STATION UNIT Pl NARRATIVE OF OPERATING EXPERIENCE November 1978 The station operated at 85.2/ electrical capacity factor with an availability of 100'5. The unit is derated to 92.0A thermal power as a result of scram reactivity restrictions.

November 1-4 The unit operated at 92$ power maintained with recirculation flow.

November 5 Reduced load to 500 MWe for condensate demineralizer change at 0005. At 0335 load was increased back to 558 MWe after demineralizer change.

November 6-9 The unit maintained 92% power with recirculation flow.

November 10 Reduced load to 500 MWe at 0130 for condensate demineralizer change. At 0558 load was returned to 560 MWe after demineralizer change.

November 11 Unit was operated at 92/ power.

November 12 Reduced load to 500 MWe for condensate demineralizer change at 0132. At 0648 load was'eturned after demineralizer change.

November 13-21 Maintained load at 92/ thermal power with recir-culation flow. On the 21st, 100/ recirc flow was reached.

November 21-24 Load slowly coasted down until 0600 on the 24th when power was reduced to 350 MWe for control rod pattern change to an all rods out configuration. At 0840 all control rods were at position 48. At 1345 pre-conditioning started at a rate of approximately 3 MWe/hr.

November 24-27 Increasing load as PCIOMR limits allow.

November 28 Reached 92/ power (all rods out).

November 29-30 The unit maintained 92%%d power with recirculation flow.
