Nuclear Subsidies May Be Slowing Transition to Clean Energy, Advocates Say, The fight to define what counts as clean energy has grown more contentious as the Biden administration’s infrastructure bill takes shape. Many activists, scientists and lawmakers agree that nuclear energy — which provides one fifth of power in the U.S — is by definition not “clean” or renewable, given that spent fuel remains radioactive and dangerous for thousands of years….. A group of staunch advocates say billions in state and federal subsidies that prop up the nuclear industry — payments that the Biden administration has signaled it may continue to support — may be slowing the transition to a truly clean energy economy…… Four days after Indian Point shuttered, on May 4, the Nuclear Regulatory Commission (NRC) approved a 20-year license renewal for two Dominion Energy reactors in Virginia, now slated to run until May 25, 2052. Half of the United States’ nuclear fleet of 93 remaining reactors will similarly be required to seek license extensions by 2040, or retire.
