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.

DOE-EM awards $37.5M to Vanderbilt University for nuclear cleanup support
The Department of Energy’s Office of Environmental Management announced on January 16 that it has awarded a noncompetitive financial assistance agreement worth $37.5 million to Vanderbilt University in Nashville, Tenn., to aid the department’s mission of cleaning up legacy nuclear waste.

The neutron age to the 1.44-ev resonance in indium has been determined from activation measurements for a D(d, n)He3 neutron source in 99.8% heavy water. Appropriately averaged and corrected indium foil activities yield the value 119.1 ± 1.5 cm2 for the age in an infinite medium. Independent theoretical calculations for exactly this experimental arrangement by Cooper (1), Goldstein and Certaine (2), and for a comparable case by Sullivan (3) all yield values in agreement with this experimental result. It appears, therefore, that there is at present no discrepancy between theory and experiment for the age of 2–3 Mev neutrons in heavy water.
