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 astatine-labeled compound shipped in the U.S.
The Department of Energy’s National Isotope Development Center (NIDC) on March 31 announced the successful long-distance shipment in the United States of a biologically active compound labeled with the medical radioisotope astatine-211 (At-211). Because previous shipments have included only the “bare” isotope, the NIDC has described the development as “unleashing medical innovation.”

In order to improve fast reactor performance, optimization of the design margin is required. Consequently, a probabilistic method for fuel rod design is being considered, and the Baysian Oriented Fuel Rod Performance Evaluation (BORNFREE) probabilistic code, which computed the statistical responses of several performance parameters concerning fuel rod integrity, was developed. The probability that the performance parameter exceeds the criterion and the design margin can be quantitatively estimated by using this code. In this study, uncertainties that affect the cladding stress, which is one of the performance parameters that restricts the lifetime of a fuel rod, were statistically simulated, and the probabilistic results were compared with the deterministic results of the conventional method. As a result of the trial computation, it was confirmed that the deterministic results were adequately conservative and exceeded the 3 upper level of the probabilistic results for any case. Furthermore, the deterministic results showed significant overestimation as compared with the probabilistic results. Consequently, it is suggested that the probabilistic method is a feasible option to optimize the design evaluation to expand the lifetime of a fuel rod.
