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.

Sam Altman steps down as Oklo board chair
Advanced nuclear company Oklo Inc. has new leadership for its board of directors as billionaire Sam Altman is stepping down from the position he has held since 2015. The move is meant to open new partnership opportunities with OpenAI, where Altman is CEO, and other artificial intelligence companies.

The purpose of this study is to investigate the influence of design parameters for the scale-up of the depleted uranium (DU) bed. The actual DU bed chosen for this study has a DU loading of 1.86 kg for a tritium capacity of 70 g and is cylindrical in shape and equipped with copper foam to enhance internal heat transfer. Based on the reference DU bed geometry, three different scale-up bed geometries to increase the amount of DU loading up to 9.3 kg were designed under different aspect ratios for comparison purposes and simulated using a three-dimensional transient DU hydride model developed in our previous studies. The simulation results are compared in terms of the evolution of the DU hydride temperature and H/U atomic ratio during the DU hydriding process. This study helps to identify key design parameters (e.g., it is critical to scale up the DU bed geometry).
