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.”

A nomograph for electron number transmission and an expression for the differential energy spectra of the penetrating electrons are developed from Monte Carlo calculations of normal incident electrons on slabs of beryllium, aluminum, iron, silver, and lead with energies in the range of 0.4 to 10 MeV. Comparison of the Monte Carlo calculations predictions with experimental data and comparison of nomograph results with Monte Carlo calculations of Berger and Seltzer show the accuracy of the proposed method. A method for calculating the dose from electrons penetrating a space vehicle is developed, based on the nomograph, the predicted energy spectra of penetrating electrons, and a geometric analysis of the vehicle.
