A bipartisan group of senators is calling on the Nuclear Regulatory Commission to accelerate the completion of a rulemaking that would establish a technology-inclusive regulatory framework for advanced nuclear reactor technologies.

In a May 15 letter to NRC Chairman Kristine Svinicki, Sens. John Barrasso (R., Wyo.), chairman of the Senate Committee on Environment and Public Works, Sheldon Whitehouse (D., R.I.), Mike Crapo (R., Idaho), and Cory Booker (D., N.J.) note that the Nuclear Energy Innovation and Modernization Act (NEIMA)—signed into law by President Trump in January 2019—requires the NRC to, among other things, complete a rulemaking to license and regulate these technologies no later than December 31, 2027.
