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.

TerraPower begins U.K. regulatory approval process
Seattle-based TerraPower signaled its interest this week in building its Natrium small modular reactor in the United Kingdom, the company announced.
TerraPower sent a letter to the U.K.’s Department for Energy Security and Net Zero, formally establishing its intention to enter the U.K. generic design assessment (GDA) process. This is TerraPower’s first step in deployment of its Natrium technology—a 345-MW sodium fast reactor coupled with a molten salt energy storage unit—on the international stage.

A process, developed for preparing dense, spherical particles of ThC2 and (Th,U)C2, consists of heating dense sol-gel oxide microspheres with lampblack in a rotating crucible under a flow of argon at 1900 to 2200°C. A precise rotational speed and a special crucible design were necessary to maintain good oxide-to-carbon contact, and to prevent the particles from sintering together and bonding to the crucible wall. The products have a high degree of sphericity and surface smoothness, depending upon the starting sol-gel oxide microspheres. The principal advantages of this process over others currently used are: 1) no elaborate blending techniques of oxide and carbon are required; 2) no densification or spheroidization step is required after the reduction reaction; and 3) the temperature of the process is lower than that of many spheroidization methods.
