Nuclear advocates fight potential cuts at DOE’s Loan Programs Office
Nearly 60 percent of staff at the U.S. Department of Energy’s nuclear-friendly Loan Programs Office may be lost through President Trump’s deferred resignation program, the Washington Examiner reported.
According to the news outlet, 123 of the 210 current LPO employees have opted into the retirement buyout, which would amount to a 58.5 percent staffing cut in the office that helps finance new nuclear projects among other energy proposals. There is a 45-day period for federal employees older than 40 to change their minds, which could impact the final number of exiting staff.
