Can U.S. Nuclear Plants Operate For 80 Years?
The nuclear industry in the United States has been at a standstill for several decades. After an extraordinary wave of construction in the 1960s and 1970s, the nuclear industry ground to a halt. A confluence of events killed off new construction, including high interest rates, cost overruns, delays, and the Three Mile Island incident that scared the public and turned it against nuclear power.
But despite the nuclear industry’s inability to build more than a handful of new nuclear power plants since the 1980s, nuclear power still accounts for about 19 percent of electricity generation in the United States, the third largest source of electricity behind coal and natural gas.
Yet the nation’s 99 reactors are mostly nearing their retirement age. Having originally been planned for 40-year lifespans, many of the reactors would have already been forced to shut down by now, with nearly all of the rest hitting their limits at some point within the next decade. Instead, more than three-quarters of them have already received a 20-year extension, putting off their retirements until the 2030s.
But in the nuclear sector, where everything takes a long time, the 2030s are rapidly approaching. With one-fifth of the country’s electricity fleet nearing retirement, and very few nuclear power plants under construction to replace what is expected to be lost, how will the U.S. cope with the lost capacity?

“Four reactors are being built, but there’s absolutely no money and no desire to finance more plants than that. So in 20 or 30 years we’re going to have very few nuclear power plants in this country—that’s just a fact,” the former Chairman of the Nuclear Regulatory Commission, Gregory Jaczko, said in a 2013 interview.
