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.

New laws offer nuclear industry incentives for existing power plant uprates
This year, the U.S. nuclear industry received a much-needed economic boost that could help preserve operating nuclear power plants and incentivize upgrades that extend their lifespan and power output.
Signed into law in 2022, the Inflation Reduction Act offers production tax credits (PTCs) for existing nuclear power plants and either PTCs or investment tax credits (ITCs) for new carbon-free generation. These credits could make power uprates—increasing the maximum power level at which a commercial plant may operate—a much more appealing option for utilities.

A new weighted diamond scheme is developed to solve the linear Fokker-Planck equation for suprathermal charged-particle transport. Such a scheme is based on the preservation of the asymptotic behavior of the linear discontinuous finite element scheme previously proposed. A simpler steplike scheme has been also considered. The results show that the weighted diamond scheme is as accurate as the linear discontinuous one, preserving the energy-position-angle correlation of charged-particle slowing down with less calculational effort. On the contrary, the steplike scheme does not preserve this coupling, giving results similar to those obtained by multigroup methods. A spectral analysis of the iteration of the scattering term shows that the convergence process can be unacceptably slow when the momentum transfer cross section is dominant. Consequently, the weighted diamond scheme has been accelerated by the S2 synthetic method, significantly improving its convergence rate. Finally, the results show that the accelerated weighted diamond scheme is highly effective for electron transport calculations.
