The purpose of the Los Alamos National Laboratory's accelerator transmutation of nuclear waste (ATW) project is to utilize a high-energy (800 to 1,600 MeV), high-current (25-to 60 mA) proton beam to generate a large neutron flux for the transmutation of nuclear wastes. Theoretical modeling efforts have been directed toward designing a device that will transmute the 2,000 kg of technetium and iodine in the Hanford waste depository along with significant quantities of actinides. Previous system studies have indicated the feasibility of such a device. However, it required 30 years to transmute 2,000 kg of technetium and 500 kg of neptunium. In the present work, the authors have expanded on the previous study and focused on a device that will significantly reduce the time required for the transmutation of the fission products. This paper presents the salient results of numerous neutronic calculations in systematic sensitivity studies made to examine this design.
