The US Department of Energy’s (DOE) Office of Energy Dominance Financing has issued a conditional commitment for a loan of up to $263m (€224m) to US fusion technology company Shine to support the construction of Chrysalis, a high-volume medical radioisotope production facility in Janesville, Wisconsin.

Shine said the production facility will create a supply of reliable and secure medical radioisotopes made with fusion and fission technology.

Millions of patients rely on medical isotopes for life-saving diagnostic imaging and cancer treatments, but most of that supply comes from overseas with limited capacity to meet demand.
