Abstract
The paper examines the neutronics and activation of Candor, a proposed design evolution of Ignitor in the direction of a device using a DHe fuel cycle. The main characteristics of the Candor machine are described. Activation calculations were done with two codes: ANITA and FISPACT. A comparison of the results for the two codes is carried out. Finally, the paper draws some conclusion on the radioactive waste management options for Candor. No Candor spent material will need to be disposed of as permanent waste in underground repositories. All materials may be recycled, if convenient, after a short interim decay. Concerning clearance, the structure may be declassified after less than 50 years of decay. For magnets, about 100 years of interim decay are necessary. Candor does reach the zero-waste option, without the need of any materials selection, low-activation materials, or further shielding. The final design of a fusion power plant with DHe3 plasmas has yet to be conceived. However, the zero-waste option is a reachable goal for such reactors, as the results for Candor have indicated.
