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.

Baranwal reviews virtual STEM lessons for U.S. tribal communities
Baranwal
In a blog post to the Department of Energy’s website on November 23, Rita Baranwal, assistant secretary for the Office of Nuclear Energy, commended recent virtual lesson projects from the Office of Nuclear Energy and the Nuclear Energy Tribal Working Group to increase STEM opportunities for Native American tribes.
The spotlighted lesson discussed in the article focused on a 3D-printed clip that turns a smartphone or tablet into a microscope with the ability to magnify items by 100 times. The Office of Nuclear Energy shipped nearly 1,000 of these microscope clips to students across the country, many of them going to U.S. tribal communities.

Verification and validation tests have been performed for the single scattering Evaluated Electron Data Library (EEDL) implemented in the Framework for Research in Nuclear ScIence and Engineering (FRENSIE). Tests compared simulation results with experimental results for electron multiple scattering and low-energy backscattering coefficients as well as simulation results from MCNP6.2. Several bivariate grid policies (unit base, correlated, and unit base correlated) and elastic scattering implementations (coupled versus decoupled) were tested. FRENSIE showed good agreement with MCNP6.2 when using the same grid policy and elastic implementation. Logarithmic-logarithmic grid policies were found to best match experimental results. For multiple scattering, an increase in accuracy was seen when using coupled elastic scattering. When using correlated or unit-base-correlated grid policies, computational results matched the experimental measurements of Hanson et al. [Phys. Rev., Vol. 84, p. 634,(1951)] for the peak amplitude of the angular distribution to within 7% and for to within , but the unit-base grid policy showed error up to 38% and 24%, respectively. For backscattering coefficients, all results below 1 keV showed large error caused by insufficiencies in the data at that energy range. The correlated and unit-base-correlated grid policies overestimated the backscattering coefficient experimental results above 1 keV, but the unit-base grid policy was in the range of the measured experimental backscattering coefficients.
