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.”

The latest version of the newly developed liquid-vapor phase-change lattice Boltzmann method, with a conjugate thermal boundary condition imposed at the solid-fluid interface, is applied to simulate numerically pool boiling from smooth, infinitely long, upward-facing, horizontal heated surfaces under controlled wall temperature conditions. A parametric study is carried out to investigate effects of wettability as well as heater and fluid physical properties on pool boiling curves, from onset of nucleation to critical heat flux (CHF) through transition boiling to stable film boiling. It is found that although a heater’s wettability has no effect on film boiling, it has important effects on nucleate boiling and transition boiling. Decreasing heater wettability shifts the nucleate and transition boiling curves to the left, decreases the maximum heat flux, decreases the minimum heat flux (MHF), and lowers the Leidenfrost temperature. With the increase of the heater’s thermal conductivity, both the MHF and the Leidenfrost temperature decrease, but this has no effect on nucleate boiling, CHF, or film boiling. On the other hand, increasing the vapor’s thermal conductivity has no effect on nucleate boiling, but it increases the MHF and decreases the Leidenfrost temperature in transition boiling as well as in film boiling.
