For the last 30 years, nuclear power has consistently provided around 20 percent of annual electricity generation in the United States, and half of the country’s carbon-free energy. But while efficiency updates increase output, allowing fewer reactors to provide the same amount of electricity, the average nuclear reactor is almost 40 years old and more than a dozen have been shuttered. Just one new reactor has come online since 1996, though two more are expected in by 2022. For a host of reasons, the legacy of nuclear power in the United States includes years-long delays in construction, power plants abandoned before they were even completed, and massive cost overruns that are passed on to the public.

Early in 2020, though, the federal Department of Energy announced its Advanced Reactor Demonstration Program, which calls for construction of two new prototype nuclear reactors within seven years. It may or may not happen, depending on who one asks: as the cost of renewable energy continues to fall and natural gas remains abundant and inexpensive, new nuclear reactors simply may not be cost-competitive.

Additionally, in April 2020, the DOE announced its Strategy to Restore American Nuclear Energy Leadership, which includes a plan to increase domestic uranium mining and establish a national uranium reserve.

The coming decade will be pivotal to nuclear power’s future in the United States. Supporters cite climate change as one very important reason to ramp up construction of new reactors, as it is ever more critical to prevent the greenhouse gases which burning still more fossil fuels would produce. Opponents point to concern about the security of nuclear material in an age of terrorism, the very long-term storage of radioactive waste (thousands of years), and the fear of an accidental release of radiation, as happened in Japan in 2011, in the former Soviet Union in 1986, and in Pennsylvania in 1979.
