OSWEGO, NY – Constellation Energy Nuclear Group’s Nine Mile Point Nuclear Station Unit 2 has started its planned spring refueling outage.

Nine Mile Point Unit 2 was taken offline on April 9 at 12:02 a.m. for the refueling outage.

The last refueling outage for Unit 2 began on April 2, 2010 and ended on May 3, 2010.

The overall duration was 30 days, 21 hours and 56 minutes.

Major Work Scope: In addition to normal refueling activities, NMP will be performing the following material improvement modifications during the outage: cooling tower distribution piping replacement, control rod blade replacements and chemical decontamination of several systems.

Several modifications in support of the Extended Power Uprate project will also be completed during the refueling outage, including high pressure turbine rotor replacement, feedwater pump motor cable replacement, steam dryer modifications, condenser expansion joint replacement and instrument set-point changes/replacements.

The Unit 2 EPU project is targeted for completion by the end of 2012.
