Unit 2 at Constellation Energy Nuclear Group’s (CENG) Nine Mile Point Nuclear Station was manually shut down at about 1:45 a.m. due to an electrical component failure on the non-nuclear side of the plant.
All safety systems responded as designed and the plant went offline as expected, safely and without incident.
Unit 2 operators took immediate and appropriate action based upon plant parameters to shut down the unit in accordance with their procedures and training. Station personnel are investigating the cause of the shutdown and will then take actions to complete necessary repairs in order to return the unit to service.
The plant is communicating with the regional grid operator, and the temporary shutdown is not expected to impact electrical service to homes and businesses in the region.
