Accelerator-driven subcritical fission in a molten salt core (ADSMS) can use depleted uranium or thorium as fuel and produce 1 GWe power while destroying the transuranics produced. ADSMS requires multiple proton beams of 800 MeV energy and 10 mA CW current. A strong-focusing cyclotron (SFC) is being developed that uses sector dipoles each configured as a flux-coupled stack, creating independent cyclotrons that can be integrated within a common footprint. This presentation will introduce a 4-stack SFC that can provide the beam power needed in an ADSMS core to destroy transuranics at the rate and proportion made in a commercial GWe power reactor while also producing 300 MWe of power, equivalent to a x5 energy amplifier.

An accelerator based neutron damage facility (AND) is proposed to generate a high-dose fast neutron flux for testing of advanced reactor materials. The facility will be implemented in two stages. In AND-1, the 350 MHz LEDA RFQ will be re-commissioned to deliver 100 mA CW proton beam at 6.5 MeV. The beam will be targeted on a sheet-flow Li target to produce fast neurons. Samples located at a target station behind the sheet flow will receive up to 10 dpa/year of neutron damage with a mean neutron energy of 1.75 MeV. In AND-2, the LEDA beam will be modulated and passed through a spectrometer to produce three 117 MHz bunch trains, and two of them will be injected to two 100 MeV strong-focusing cyclotrons (SFC). The beams extracted from the two cyclotrons will be targeted in opposite directions onto sheet-flow Pb targets. Samples located in the space between the two targets will receive ~140 dpa/year of fast neutron damage with mean neutron energy ~10 MeV. AND-1 and AND-2 will provide the fast neutron flux needed for life-cycle damage studies for advance reactor technologies and for first-wall simulations for fusion systems.
