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 1000-MW(electric) fusion power reactor concept based on electrochemically induced D-Dn, D-Dp, and deuterium-tritium reactions is presented. A D- He reaction is not possible because He is not absorbed in the electrode. The concept of a tube-type fuel cell is presented. The inner surface of the tube is laminated with palladium. The cell provides a large cathode surface and efficient heat transport to the water coolant. The fuel assemblies and bundles of fuel tubes are installed in the pressure vessel. The reactor system is very similar to a pressurized water reactor, though the reactor internals are much simplified due to the elimination of fission fuel pellets and control rods. The spatial power distribution of the reactor core is very flat compared with that of fission reactors.
