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.

The development of vanadium alloys as fuel element cladding materials in sodium-cooled, ceramic-fueled fast breeder reactors was reviewed. Compared to stainless steel, certain vanadium alloys have advantageous nuclear and thermal characteristics, elevated temperature strength, and potential resistance to fast-neutron embrittlement. The compatibility of vanadium alloys with flowing sodium and with ceramic fuels was identified as an area in which more data are necessary. A comparison of economics and performance was made for vanadium-alloy and stainless-steel cladding in a carbide-fueled LMFBR. The power costs depended strongly on the projected fabrication cost of vanadium-alloy and stainless-steel tubing. Several fabrication costs as well as different cladding thicknesses were considered. For a core coolant outlet temperature of 110°F in the vanadium designs, an economic break even point with 316-SS was reached at vanadium-alloy tubing costs of ∼$3.50/ft in the vented design and $2.85/ft in the nonvented design. Stainless steel was considered inadequate at that coolant temperature. With the core coolant outlet temperature at 1 000°F in all core designs, the economic break even vanadium tubing cost was ∼30% lower. Power costs were generally a few hundredths of a mill/kWh higher with vanadium cladding at the same burnup. This cost differential could be eliminated since vanadium alloys may be capable of a slightly higher burnup than stainless steel, due to their higher end-of-life ductility. Differences in nuclear performance characteristics such as fuel inventory, breeding ratio, and doubling time were <1% for all cladding materials and thicknesses studied. Doppler and sodium-void reactivity effects were 5 to 10% more favorable with vanadium-alloy cladding than with stainless steel. Based upon the available economic and performance data, a vanadium alloy appears to be an attractive potential alternate to stainless steel for LMFBR cladding.
