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.

First International Nuclear Science Olympiad held in Philippines
Fifty-five high schoolers representing 14 Asian countries participated in an inaugural nuclear science competition earlier this month in the Philippines.
The event was held in the run-up to the United Nations’ International Youth Day, which is celebrated worldwide on August 12 to recognize and encourage the potential of young people as active partners in the global society. The nuclear field presents many opportunities for the next generation of scientists and engineers.

The high fission product retention potential of coated particle fuel combined with inherently passive temperature controls guarantee almost complete fission product retention during an accident in a small modular high-temperature reactor. Extensive experimental results provide the basis for this claim to inherent safety. Models and codes have been developed to (a) predict realistic, or at least conservative, overall release rates from the primary circuit, (b) reduce the large number of experimental results to a small set of characteristic coefficients, and (c) predict release beyond experimental conditions. Conservative predictions of release from the core have been done using a traditional pressure vessel model for release from fuel particles and simplified diffusion models for fission product transport. This approach is based on experimental work that has been done on nearly all possible accident conditions and is limited by the finite number of experiments. Data reduction has been achieved with two different modeling approaches combined into a new model that is equally relevant to all volatile fission products. The safety design of the 200-MW(thermal) HTR-Modul is based on Kernforschungsanlage Jülich experimental results from fuel accident condition performance testing and the modeling effort has been applied to a safety review.
