The Perry Nuclear Power Plant is operating normally Tuesday after an emergency was declared.
Akron-based FirstEnergy Corp, operators of the power plant in Lake County, notified the Emergency Operations Center in Kirtland at 3:44 a.m. about the alert, classified as the second-lowest level of emergency classification at nuclear power facilities.
Just after 9 a.m., the event was terminated and the plant returned to normal operating status, Lake County Commissioners said in a press release.
Officials said an instrument malfunction caused the emergency to be declared. It indicated a false reading in a plant ventilation system. The system processes and filters gas from the plant's turbine. The monitor instrument will be repaired Tuesday.
No protective actions had to be issued to the public and no radiation was released to the environment. Technicians took multiple gas samples to verify the reading was incorrect.
Earlier this year, a cooling pump at the nuclear plant failed a test for the second time in less than a year, causing officials to shut down the plant for about a week.
