The U.S. Nuclear Regulatory Commission is advancing sweeping reforms under the ADVANCE Act of 2024 and a May executive order from President Donald Trump to help reach 400 gigawatts of nuclear power by 2050.

“A lot of it is going to come out by the end of March, but then there will be a second wave of things that will come out in April and in May,” Nuclear Energy practice leader Jeff Merrifield said in an interview with Politico Pro. “It is a broad set of changes.”
