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.

IEA report: Challenges need to be resolved to support global nuclear energy growth
The International Energy Agency published a new report this month outlining how continued innovation, government support, and new business models can unleash nuclear power expansion worldwide.
The Path to a New Era for Nuclear Energy report “reviews the status of nuclear energy around the world and explores risks related to policies, construction, and financing.”

The age of fission neutrons to indium-resonance energy has been measured in AGOT graphite using the point-source technique. Corrections to the data arising from the following factors were investigated: (a) source and foil size, (b) finite dimensions of medium, (c) higher- and/or lower-energy activations, and (d) angular sensitivity of detector foils. The age was determined to be 307.8 ± 1.9 cm2; the fourth and sixth moments were 6.58 ± 0.05 × 106 cm4 and 3.84 ± 0.06 × 1010 cm6, respectively. These agree well with the values of 307.4 ± 1.0 cm2, 6.59 ± 0.06 × 106 cm4, and 4.01 ± 0.09 × 1010 cm6 obtained by Monte Carlo calculations.
