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 technique has been proposed to increase the efficiency of hydrogen production from water by gamma-ray radiolysis as an effective use of radioactive waste. This is possible by putting special metal structures into water to enhance the conversion of mega-electron-volt-range gamma rays to low-energy electrons, which escape from metal into water. The experimental results showed that hydrogen production could be significantly enhanced by carefully controlling the thickness of metal components and the proximity with adjacent metal components. A honeycomb-like structure composed of stainless steel tubes was confirmed to provide the best performance for hydrogen production. These experimental results successfully demonstrated that the modification of metal structure can control the energy and the number of electrons escaping from the metal and actually leads to enhancement of hydrogen production in water.
