Exelon Reactor Operator Visits Classes at MCHS
(Minooka) – MCHS science teacher Matt Minich recently welcomed guest speaker Dan Potochnic, a nuclear reactor operator with Exelon, to talk to students about nuclear chemistry and power plant operations.
During his presentation, Potochnic explained to students how splitting atoms through fission is used to create nuclear energy.
“When atoms are split, they release heat,” explained Potochnic. “This heat is used to create steam that then spins generator turbines at over 1,800 revolutions per minute to create electricity.”
Through this process, Potochnic stated that Exelon’s plant in Braidwood produces enough electricity in one day to light over two million homes.
“One benefit to nuclear energy is that it is friendly to the environment,” Potochnic added.
He continued that one nuclear fuel pellet, which is the size of a pencil eraser, could produce as much energy as three barrels of oil or one ton of coal without producing carbon dioxide by-products. These same by-products, which are produced when energy is created by burning coal, oil and other natural resources, increase greenhouse gases and are harmful to the environment.
Potochnic also answered students’ questions about overall plant safety and security.
Potochnic closed his presentation by providing details about possible career opportunities in nuclear energy production, such as being an engineer or skilled professional.
“Being an operator is challenging but rewarding,” he said. “Operators actually receive more initial training than space shuttle pilots, and receive more continuous training than doctors.”
