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.”

An actively-cooled dump module design is being developed for use in the MFTF-B long pulse neutral beamlines. The modular approach allows for application of the same design inseveral different areas, such as positive ion dumps, neutral dumps and beamline apertures. The dump modules are required to dissipate up to 1.2 MW of beam power with peak heat fluxes as high as 1500 W/cm2 for a lifetime of 50,000 cycles. The modules are constructed from two rows of 1.91 cm O.D. × 0.318 cm wall (0.75 × 0.125 in.) oxygen-free copper tubing, staggered to achieve maximum optical density. The tubes are bent into a “C” shape and connected to large diameter manifolds at each end. Thermal analysis of conduction in the tube wall has been performed to predict inner wall heat flux and tube wall temperature profiles. The results have been used both as an input to critical heat flux assessment as well as an input to NASTRAN stress analysis. The NASTRAN analysis has shown that tube deflections will be within allowable limits and that the design life will be ≅ 100,000 cycles.
