U.S. Senator John Barrasso (R-WY), chairman of the Senate Committee on Environment and Public Works (EPW), joined with Sens. Sheldon Whitehouse (D-RI), Jim Inhofe (R-OK), Cory Booker (D-NJ), Mike Crapo (R-ID), Deb Fischer (R-NE), Shelley Moore Capito (R-WV), and Joe Manchin (D-WV) to introduce S. 512, the Nuclear Energy Innovation and Modernization Act (NEIMA).

Senators Robert Casey (D-PA), Tammy Duckworth (D-IL), Jeff Flake (R-AZ), Thomas Carper (D-DE), Mike Rounds (R-SD), Christopher Coons (D-DE), John Cornyn (R-TX), Orrin Hatch (R-UT), Gary Peters (D-MI), and John Kennedy (R-LA) have also joined in support of the legislation as co-sponsors. 

S. 512 will promote innovation in the nuclear sector by enabling processes for licensing new reactors. This legislation will modernize the Nuclear Regulatory Commission (NRC) by establishing new transparency and accountability measures to the commission’s budget and fee programs. The bill will develop the regulatory framework necessary to enable the licensing of advanced nuclear reactors.

Additionally, the Act will improve the efficiency of uranium regulation. Finally, it will bring transparency and accountability to the process by which the Department of Energy (DOE) disposes of the American public’s stockpile of excess uranium.


“American nuclear energy has provided affordable, safe, and reliable power for decades. Our bipartisan legislation will allow for innovation in the nuclear sector by simplifying regulations at the Nuclear Regulatory Commission. The commission needs a modern regulatory framework that is predictable and efficient. Advancements in nuclear energy development will create jobs, lower costs, and contribute to America’s energy security." - Chairman John Barrasso

“Next-generation nuclear reactors could help address the serious threats we face from climate change and may ultimately play a key role in reducing nuclear waste. But the federal government’s outdated approval process slows these promising new technologies.  We need a more efficient regulatory framework that accounts for the big advances we’ve made in nuclear science. This legislation will give our nuclear regulator the flexibility it needs to bring new, safe reactors online to produce carbon-free energy.” - Senator Whitehouse

“I am pleased to join my colleagues in reintroducing this legislation. While our traditional power plants have been a reliable source of clean and affordable energy for decades, and will continue to be, it is important that we consider the future of nuclear energy.  This bill not only updates the regulatory structure for existing plants but creates a predictable NRC review process for advanced reactors and new technologies. By creating a regulatory framework that is compatible with a variety of technologies we ensure safety without compromising innovation. I look forward to working with Chairman Barrasso on this important piece of legislation.” - Senator Inhofe

“We must accelerate our transition to a carbon-free energy future. This bipartisan bill will help provide the modernized regulatory structure needed at the NRC for safe, advanced nuclear reactors to move from concept to reality.” - Senator Booker

“Using more clean nuclear energy must be part of any forward-looking domestic energy portfolio. This bipartisan measure is important to Idaho because it will help ensure that the work being done at Idaho’s National Lab will have a path through the Nuclear Regulatory Commission and on to the commercial market. NEIMA pushes the commission to modernize so that it has the ability to license advanced reactors in a safe, timely, and transparent manner.  It will also bring more openness and accountability to the NRC’s budget and fees, which will help stakeholders in-and-out of government better understand what the agency is doing with its resources.” - Senator Crapo

“The Nuclear Energy Innovation and Modernization Act would help keep electricity prices affordable for Nebraska families. It would also increase transparency at the Nuclear Regulatory Commission, streamline the licensing process for advanced nuclear technology, and provide relief for uranium producers by limiting government involvement in the marketplace. With this bipartisan legislation, we can strengthen America’s competitive edge and advance the benefits of nuclear technology.” - Senator Fischer

“As chairman of the Clean Air and Nuclear Safety subcommittee, I understand the importance of encouraging innovation in our nuclear sector. I’m glad to support this bill that will help establish new processes for reactors, so we can continue growing our economy by making use of multiple energy sources, including nuclear.” - Senator Capito

“I am proud to join my colleagues in introducing this important legislation that will help modernize the Nuclear Regulatory Commission and support the advancement of our nation’s nuclear industry which provides electricity to millions of people and businesses. This legislation will create greater transparency and accountability within the NRC to improve dynamics and prepare for the future of nuclear. I have always said we need an all-of-the-above energy policy and the success of nuclear energy is imperative to achieving that goal.” - Senator Manchin
