• Commissioning and characterization of UTA and instrumentation system• Validate computer models and simulations

UTA Driven by a Linac

Successfully operational fully coupled system:– Superconducting linac coupled to UTA– Neutron production verified and validated– Mo-99 and other FF are produced

Future Steps

• Niowave will continue work with Y-12 and ANL to improve and scale up our processes

• In the next 2 years we will be producing:– 10 Ci per week of Mo-99 and Xe-133– 10 Ci of other beta emitting fission fragments

• Revenue from therapeutic beta emitters:– Coproduced during uranium fission– Will fund scale up to 10 kCi/week
