Christopher Hanson, the new chairman of the Nuclear Regulatory Commission, and Rich Glick, leader of the Federal Energy Regulatory Commission, replace Republicans who led the panels under President Donald Trump. The NRC regulates commercial nuclear power plants and other uses of nuclear materials, including in medicine, while FERC regulates interstate transmission of electricity, natural gas and oil. It also reviews proposals to build liquefied natural gas terminals, interstate natural gas pipelines and hydropower projects. He also has served as a senior adviser in the Energy Department’s Office of Nuclear Energy and other department roles in the Obama administration.
