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.

Monte Carlo analysis of the Oak Ridge National Laboratory measurements of the fission neutron yield due to the absorption of a 2200 m/sec neutron in 233U and 235U, respectively, yields: = 2.3019 ± 0.0086 and = 2.0746 ± 0.0078. The analysis was confirmed by calculating measured quantities employed by the experimentalists in their determinations of η2200.
