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 zirconium cobalt bed has been designed with large conductance, low porosity filters and a large bed containment mass to improve the rate of hydriding. By ensuring that sufficient thermal ballast is available, the hydriding rate will be exponential thereby approaching the desired isothermal limit. Loading dependencies upon initial tank pressure and bed capacity at ambient temperature have been studied. Hydrided ZrCo powder was observed to spontaneously combust in air at ambient temperature after undergoing 12 hydriding/dehydriding cycles. ZrCo powder progressively fragments into submicronic fines with continued bed cycling up to 35 bed cycles. No permanent degradation in the rate of hydrogen loading onto ZrCo has been observed during 95 hydriding/dehydriding cycles.
