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.

Three new difference schemes for solving the neutron transport equation are presented. In some situations these new methods give smoother results than the diamond difference scheme, without sacrificing second-order accuracy. Iteration schemes for solving the new difference equations are given, and convergence acceleration devices are discussed. Numerical results illustrate the behavior of these new schemes in a variety of situations.
