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.

Fermilab center renamed after late particle physicist Helen Edwards
Fermi National Accelerator Laboratory’s Integrated Engineering Research Center, which officially opened in January 2024, is now known as the Helen Edwards Engineering Center. The name was changed to honor the late particle physicist who led the design, construction, commissioning, and operation of the lab’s Tevatron accelerator and was part of the Water Resources Development Act signed by President Biden in December 2024, according to a Fermilab press release.

Two new methods for designing modular stellarator coils are presented. Stellarator coils provide necessary magnetic field to produce the plasma shape for a desired magnetohydrodynamic (MHD) equilibrium. The methods optimize a continuous current on a surface - i.e., coil current is represented by a continuous-current sheet on a toroidal winding surface - and the process of coil cutting is not addressed. In contrast to previously published continuous-current methods that optimize coil current by minimizing the flux at the plasma boundary, the new methods presented in this paper search for optimal solutions by minimizing the displacement of the plasma boundary, i.e., the last closed magnetic surface. The physical displacement of the plasma boundary is computed from the magnetic field normal using linear MHD perturbation theory. A comparison with two similar continuous-current codes is given in terms of both methodology and results. The new codes show modest improvement over previously published continuous-current codes.
