Arkansas Nuclear One , a few miles northwest of Russellville, is among 61 commercial nuclear power facilities in the U.S. operating ninety-nine nuclear fission reactors. Constructed in the late 1970s and currently owned by Entergy, Arkansas Nuclear One operates two pressurized light water reactors with the capacity to generate 1,776 megawatts of electricity, enough to power 355,000 homes and businesses. The reactors are cooled by water drawn from Lake Dardanelle. Thick white steam rising from the power plant's iconic six-story hyperbolic cement tower is visible for miles. Locals, Russellville Mayor Randy Horton says, divine weather conditions from the plume. “In the old days, we would drive to the base of the cooling towers and fish in the hot water discharge stream. It never was threatening, never been scary.” Horton says the power plant is a good neighbor, providing jobs--and lots of clean safe energy.
