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.

Glass strategy: Hanford’s enhanced waste glass program
The mission of the Department of Energy’s Office of River Protection (ORP) is to complete the safe cleanup of waste resulting from decades of nuclear weapons development. One of the most technologically challenging responsibilities is the safe disposition of approximately 56 million gallons of radioactive waste historically stored in 177 tanks at the Hanford Site in Washington state.
ORP has a clear incentive to reduce the overall mission duration and cost. One pathway is to develop and deploy innovative technical solutions that can advance baseline flow sheets toward higher efficiency operations while reducing identified risks without compromising safety. Vitrification is the baseline process that will convert both high-level and low-level radioactive waste at Hanford into a stable glass waste form for long-term storage and disposal.
Although vitrification is a mature technology, there are key areas where technology can further reduce operational risks, advance baseline processes to maximize waste throughput, and provide the underpinning to enhance operational flexibility; all steps in reducing mission duration and cost.

The hope that fusion reactors will have fewer radiological hazards than competing fission technologies is an important rationale for fusion research. Estimates of the radiological hazard due to reactor accidents, occupational exposures, and waste disposal of reference fusion and fission designs; the Mirror Advanced Reactor Study (MARS); and a liquid-metal fast breeder reactor (LMFBR) indicate that fusion may enjoy substantial quantitative advantages over fission but that such advantages are neither sure to be achieved nor necessarily sufficient for fusion to be perceived as qualitatively superior to fission. The possibility of achieving maximum reductions of hazard is explored by analyzing the effects of relatively minor modifications of the MARS design, using completely different structural or breeder/coolant materials, and changing the fusion fuel cycle. Minor modifications, such as elemental tailoring of structural and coolant materials, result in reductions of one to two orders of magnitude in each class of hazard. Using different reactor materials, such as vanadium alloy or high-purity silicon carbide blanket structure, can result in even greater reductions. Other combinations, such as a molybdenum alloy structure cooled by liquid lithium, can be as hazardous as an LMFBR. Using the only other promising fuel cycle, catalyzed deuterium-deuterium, accident hazards can be reduced one to two orders of magnitude and waste disposal hazards by a factor of 4.
