1 NIAGARA M0llAWK POWER CORPORATION NINE MILE POINT NUCLEAR STATION UNIT #1 NARRATIVE OF OPERATING EXPERIENCE JUNE 1984 Nine Mile Point Unit #1 returned to service from a major refueling and overhaul outage during the month of June. The station operated with a monthly availability factor of 28.6% and a net design cicctrical rating capacity factor of 19.3%.

Capacity / Availability losses were due to the foJ10 wing:

The station was shutdown for a planned refueling up to June 13th when the first reactor start up was. commenced.

The plant was shut down due to electromatic relief valve test failures. A second reactor start-up was commenced on June 16th and relief valve failures again forced a plant shutdown. A third reactor startup was commenced on June 22nd.

The Turbine / Generator was placed on line at 0500 June 23rd after two Turbine /

Generator trip tests.

The plant operated normally reaching top load on June 27th. Smoldering insulation on the #13 shaft driven feedwater pump caused a load reduction to 36% power at 0430 on the 27th'.

The plant returned to full load again on the 28th and operated normally the rest of the month.
