According to Exelon Generation Communications Manager Bill Stoermer, there was never any threat to the public or plant employees when the unit malfunctioned.
"When you look at nuclear power plants, the reactor is really what makes us a nuclear power plant, but producing steam, going over to the turbine and turning the generator to make electricity," Stoermer says. "That's really the same at any power plant, whether it's a nuclear power plant or not, so when we talk about the non-nuclear side, this particular thing was on the turbine side, so it was a pump that provides some cooling water to the turbine, it tripped off."
Half of the plant is still offline while the company decides how to fix the problem.
"Once our technicians are done troubleshooting and we've got whatever parts we need, we'll make the repairs and get the unit back online as soon as we can," he said.
It is unknown how long the repair process will take.
Just before 8:00 p.m. on March 20, the Unit 2 reactor at the Byron Generating Station was shut down for a main generator cooling pump malfunction.
Both the generator and the pump are not on the nuclear side of the plant. The shutdown was done safely and with no issues. The cause of the pump malfunction is currently being investigated by operators.
The station's Unit 1 is still operating at full power.
