The James A. FitzPatrick nuclear power plant near Oswego, New York notified the Nuclear Regulatory Agency that on October 5, 2012, it lost offsite power to its sole reactor. The loss of power caused automatic systems including the Reaction Water Clean-up system to activate. The reactor was out of service for maintenance at the time of the incident.

FitzPatrick officials noted in their report: “…the four Emergency Diesel Generators (EDG) started in response loss of power but the EDG ‘A’ output breaker did not automatically close.”

The generator breaker was not the only system to malfunction during the incident. As FitzPatrick reported: “a major loss of Emergency Response communication capability has occurred. Some of the systems not available include: Emergency Notification System (ENS), Health Physics Network (HPN), and commercial phone communication.”

It took over eight hours for offsite power to be restored to the site.
