A coolant leak in one of Cooper nuclear power plant’s main turbine generators in southeast Nebraska has been repaired.
The hydrogen leak was repaired before 6 p.m. November 15, said Nebraska Public Power District spokesman Mark Becker. The leak was discovered earlier in the day by maintenance workers.
The leak didn’t represent a safety threat, and it was not in the power plant’s nuclear systems, officials said. Hydrogen is used to help cool a main turbine generator.
The plant near Brownville, NE, continued operating after the leak was found Tuesday morning.
The utility notified regulators about the problem, and issued what the Nuclear Regulatory Commission calls a notice of unusual event.
