Title Reactor Physics Analysis of CANDU HMR Fuel Cycle Options.
Publication Date 2013
Media Count 4p
Personal Author R. J. Ellis
Abstract The Office of Fuel Cycle Technologies (FCT) of the United States Department of Energy Office of Nuclear Energy (DOE-NE) is performing an evaluation and screening of potential fuel cycle options to help prioritize future research and development decisions. (1) Pressurized Heavy Water Reactor (HWR) fuel cycle options at equilibrium were analyzed in support of these efforts. The enhanced CANDU 6 (EC6) (2) reactor was chosen to represent this class of reactors. Three single-stage fuel cycle options and one two-stage HWR-PWR synergistic option were analyzed. The four HWR options were (1) HWR once-through operation with natural uranium (NU) oxide fuel HWR-O(NU); (2) HWR with continuous recycle of Pu and recovered uranium (RU), where the RU is mixed with an equal mass of fresh NU oxide HWR-R(Pu,RU); (3) HWR recycle of recovered transuranics (TRU) mixed with an equal mixture of RU and NU oxide HWR-R(TRU,RU); and (4) HWRs feeding recovered Pu and RU into a second-stage pressurized water reactor (PWR) HWR-PWR(Pu,RU). References 24 provide specific details and parameters representing the EC6 design and aspects of CANDU reactors in general. The reactor is cooled and moderated with heavy water and is fueled by NU oxide in pellets assembled in 37-element fuel assemblies.
