A western Pennsylvania nuclear power plant had to evacuate a turbine building for about 90 minutes due to excess carbon dioxide.
The incident began at 8:23 a.m. Friday at FirstEnergy Corp.’s Beaver Valley Nuclear Power Station in Shippingport, PA, about 35 miles northwest of Pittsburgh, said officials at the Nuclear Regulatory Commission (NRC).
The incident ended up cleared by 9:55 a.m. and the NRC classified it as an “unusual event,” the lowest of four emergency levels classified by the agency, said NRC spokesman Neil Sheehan.
The NRC will review FirstEnergy’s investigation and any actions the utility takes to fix the problem.
No one suffered any injury from the problem and the plant’s electrical output did not suffer from the incident.
The turbine unit is in the same reactor unit that jus shut down for two weeks by a malfunctioning generator.
