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.

Neutron total cross sections of elemental beryllium are measured from 1 to 10 MeV with good precision. Differential neutron elastic scattering cross sections are measured from 4.5 to 10 MeV at intervals of ≈0.5 MeV and at ≈100 angular steps distributed between ≈18 and 160 deg at each incident energy. Concurrently, differential cross sections for the emission of a discrete inelastic neutron group corresponding to an excited level at (2.43 ± 0.06) MeV are determined over the same incident energy and angular range. Angle-integrated elastic scattering cross sections are deduced from the observed differential values to accuracies of ≈2.5%, and angle-integrated inelastic scattering cross sections to accuracies of ≈10%. The experimental results are compared with values given in ENDF/B-V, with attention to discrepancies and implications. Qualitative reaction mechanisms are suggested.
