Nine Mile Point Unit 2 automatically shut down at about 4:30 p.m. Monday when a worker inadvertently contacted a highly sensitive plant component. All safety systems responded as designed and the plant went offline as expected, safely and without incident.
This issue is unrelated to last week’s shutdown, which was caused by an electrical equipment failure.
Nine Mile Point’s reactor protection system uses highly sensitive equipment to monitor a host of plant conditions and components, constantly looking for signs of a potential issue. When an anomaly is identified, the system is designed to automatically shut down the reactor.
Station operators informed the Nuclear Regulatory Commission and state officials of the issue. The temporary shutdown does not present a risk to public health and safety and is not expected to impact electrical service to homes and businesses in the region.
Nine Mile Point 1 and 2 are owned and run by Constellation Energy Nuclear Group.
