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.

The dynamics of continuously fueled fission reactors based on an isothermal and nonlinear description of neutron/nuclide interactions is considered. In general, and for a plausible range of operational fueling conditions, such systems are absolutely stable, at most displaying converging spiral phase-space trajectories.
