Nuclear is ready now
Michael Goff
I don’t think we’ve ever had a busier year in the Office of Nuclear Energy, and it’s probably been decades since we’ve had this much momentum within the overall U.S. nuclear industry.
President Trump and Energy Secretary Wright have made very clear the important role that nuclear must play in meeting our energy needs, and that’s well demonstrated by the four executive orders that the president signed [more than] 375 days ago. In nuclear, we’re now talking about days, not years.
Those EOs set a goal for the United States to quadruple the amount of nuclear that we have. We need to go from the 94 reactors that we have operating right now, which generate roughly 100 gigawatts of electricity, to 400 gigawatts by 2050.
