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.

Taking shape: Fusion energy ecosystems built with public-private partnerships
It’s possible to describe fusion in simple terms: heat and squeeze small atoms to get abundant clean energy. But there’s nothing simple about getting fusion ready for the grid.
Private developers, national lab and university researchers, suppliers, and end users working toward that goal are developing a range of complex technologies to reach fusion temperatures and pressures, confounded by science and technology gaps linked to plasma behavior; materials, diagnostics, and electronics for extreme environments; fuel cycle sustainability; and economics.

In this paper we present and discuss recent experimental and theoretical advances concerning the redistribution process, the control of target temperature, and the effect of deuterium-tritium (D-T) aging on the optimum laser shot temperature at the Laser Mégajoule (LMJ) facility.We introduce two analytical models to provide a better understanding of thermal target behavior. On one hand the first model describes the evolution of the D-T layer temperature, which cannot be recorded experimentally. On the other hand the second model highlights the necessity for the optimum laser shot temperature (i.e., 1.5 K below the triple point) to be adapted to the aging of the target.The analytical considerations are completed with experimental results obtained with D2 taken as a reference system to investigate the properties of D-T in LMJ targets.
