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.

The 2025 ANS election results are in!
Spring marks the passing of the torch for American Nuclear Society leadership. During this election cycle, ANS members voted for the newest vice president/president-elect, treasurer, and six board of director positions (four U.S., one non-U.S., one student). New professional division leadership was also decided on in this election, which opened February 25 and closed April 15. About 21 percent of eligible members of the Society voted—a similar turnout to last year.

The inertial confinement fusion design requires smooth and uniform deuterium-tritium (D-T) ice layers in a spherical shell. One of the most important factors affecting the ice layer quality is the thermal environment around the capsule, which determines the low-mode thickness asymmetries of the D-T ice layer. In this paper, we report the thermal simulation results for the hohlraum cryogenic target in the China Academy of Engineering Physics, focusing on the ice layer roughness analysis and low-mode control. The simulations were carried out with a computational fluid dynamics code. A calculation procedure based on the dynamic mesh method was applied to predict the D-T ice layer profile. The sensitivity of ice layer low-mode roughness to some operating and thermal condition has been investigated. The conclusions in this paper provide better direction for our cryogenic target’s further design and improvement.
