Five GovCon Contractors Supporting Government Nuclear Programs

Nuclear power accounts for nearly 20 percent of the electricity generated in the United States, according to the Department of Energy, which is responsible for advancing the government’s mission to secure domestic sources of energy.

The government contracting sector plays an important role in that mission. As of December 2020, the United States had 94 operating commercial nuclear reactors at 56 nuclear power plans across 28 states, the U.S. Energy Information Administration reported. Nuclear technology investor Bill Gates expects innovations in nuclear energy to make it more appealing to countries in 2021 and beyond.

The Potomac Officers Club — a division of Executive Mosaic — features five executives from contractors supporting the U.S. government’s nuclear energy and security programs.
