Division Spotlight
Nuclear Nonproliferation Policy
The mission of the Nuclear Nonproliferation Policy Division (NNPD) is to promote the peaceful use of nuclear technology while simultaneously preventing the diversion and misuse of nuclear material and technology through appropriate safeguards and security, and promotion of nuclear nonproliferation policies. To achieve this mission, the objectives of the NNPD are to: Promote policy that discourages the proliferation of nuclear technology and material to inappropriate entities. Provide information to ANS members, the technical community at large, opinion leaders, and decision makers to improve their understanding of nuclear nonproliferation issues. Become a recognized technical resource on nuclear nonproliferation, safeguards, and security issues. Serve as the integration and coordination body for nuclear nonproliferation activities for the ANS. Work cooperatively with other ANS divisions to achieve these objective nonproliferation policies.

Three-dimensional neutronics models of the SOLASE-H fusion-fission reactor have been analyzed by Monte Carlo. In this design, light water reactor (LWR) fertile ThO2 fuel bundles are enriched in the fissile isotope 233U and then shipped for burning in the LWRs. A concept where the fertile fuel bundles constitute a lattice configuration with the moderator-multiplier material is investigated. Parametric lattice calculations as a function of the neutron moderator-multiplier to fuel volume ratio (vm/vf) in the lattice show that it is possible in such a concept to enhance the fissile nuclei production density in the fertile fuel, compared to cases where a lattice configuration is not used. This leads to shorter times to attain projected average fissile enrichments, using substantially smaller fuel inventories. Surrounding the whole reactor cavity with the neutron multiplier is found to enhance the fissile breeding in the radial blanket. Severe asymmetries in the spatial distribution of the fissile enrichment are detected and suggest the necessity of elaborate fuel irradiation and management programs in the case of a laser-driven system. The concept of a lattice configuration and the use of the whole solid angle surrounding the fusion source for neutron multiplication are recommended for adoption in future magnetic and inertial confinement fusion-fission hybrid reactor designs.
