Nevada officials are declaring victory over Yucca Mountain — even as some experts cautioned the federal government’s pivot away from the long-stalled and controversial nuclear waste repository may create new problems. The proposal calls for allowing the Nuclear Regulatory Commission to revise how waste is classified for more flexibility and to revive a nuclear waste disposal fee that courts had previously blocked. Yucca Mountain was designated as the United States’ sole nuclear waste repository in 1987 through an amendment to the Nuclear Waste Policy Act. “Until the law changes and a solution to nuclear waste storage is found, I will never stop fighting to keep nuclear waste out of Nevada and ensure any decision about nuclear waste has the consent of impacted communities,” Sen. Jacky Rosen, D-Nev., wrote in a social media post after Tuesday’s news. In an interview, the couple said there’s “no safer place” in the U.S. to store nuclear waste than Yucca Mountain.
