DOE selects first companies for nuclear launch pad
The Department of Energy’s Office of Nuclear Energy and the National Reactor Innovation Center have announced their first selections for the Nuclear Energy Launch Pad: three companies developing microreactors and one developing fuel supply.
The four companies—Deployable Energy, General Matter, NuCube Energy, and Radiant Industries—were selected from the initial pool of Reactor Pilot Program and Fuel Line Pilot Program applicants, the two precursor programs to the launch pad.

This session explores the ongoing evolution and critical testing of Radioisotope Thermoelectric Generators (RTGs) that are essential for long-duration space missions. Attendees will dive deep into the legacy and recent refurbishment of the General-Purpose Heat Source (GPHS) RTG Flight Unit 5, including its thermal vacuum testing and power performance predictions. Additionally, presentations will cover the current development status of the Next Generation RTG Mod 1, offering a comprehensive look at both our historical engineering foundations and future power systems.
