Seth Cohen, the Department of Energy’s chief counsel for nuclear law and policy, announced over the weekend that he is leaving the government.
“So, the cat is out of the bag … this past week I decided to transition out of the federal government,” Cohen said Saturday on his LinkedIn page.
Cohen said he was proud of the work the Donald Trump administration accomplished on nuclear power both at DOE and the Nuclear Regulatory Commission.
Cohen, who has been with DOE roughly a year, cited progress on issues such as nuclear lifecycle campuses, a pilot program for advanced reactors, NRC reforms and other programs.
“I came to believe we have cleared the biggest hurdles,” Cohen said.
Since joining the government in May 2025 from the Kirkland & Ellis law firm, Cohen has worked in a variety of positions for DOE, NASA and NRC.
