Helion secures new licenses from Washington
Last week, Everett, Wash., fusion start-up Helion Energy announced that it has received its radioactive materials license and radioactive air emissions license from the state of Washington.
According to the company, these milestones make it “the first company in the world to secure the regulatory licenses needed for a fusion power plant” and represent confirmation that it has the needed facilities, trained personnel, and safety programs in place to safely operate its fusion machine.

Measurements of the double-differential thick-target neutron yield are made for 75- and 120-MeV 12C5+, 153-MeV 16O5+, and 40-MeV alpha particles bombarding carbon, aluminum, copper, and lead targets. The measured data are parameterized by using the two-component moving source model. The systematic variation of the equilibrium neutron (EN) yield with incident ions and targets is analyzed by using the thus-obtained moving source parameters, and a simple expression is proposed to describe the systematics in the EN yield. The systematic change in the nonequilibrium neutron (NEN) yield was formulated to a simple expression by using the local hot spot model. The proposed expression reproduced well the measured EN and NEN yields.
