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.

Production of 18F, a positron emitter, with fast protons from D-3He fusion reactions and oxygen (18O) impurities in a large tokamak is studied numerically. A high-energy deuterium beam is used for proton production enhancement. The yield of 18F is found to be optimized in a somewhat dirty plasma with an effective ionic charge number of Zeff ∼ 5 and doubled by the inclusion of the possible resonance in the 18O(p,n)18F reaction. The yield in the deuterium beam-injected 3He plasma is 1000 times larger than by standard methods using a cyclotron. A comparison is also made with the yield in an advanced plasma regime.
