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.

Taking shape: Fusion energy ecosystems built with public-private partnerships
It’s possible to describe fusion in simple terms: heat and squeeze small atoms to get abundant clean energy. But there’s nothing simple about getting fusion ready for the grid.
Private developers, national lab and university researchers, suppliers, and end users working toward that goal are developing a range of complex technologies to reach fusion temperatures and pressures, confounded by science and technology gaps linked to plasma behavior; materials, diagnostics, and electronics for extreme environments; fuel cycle sustainability; and economics.

To investigate tritium extraction technology for the helium-cooled molten lithium test blanket module, a tritium extraction method in the liquid breeder based on the gas-liquid contactor concept has been studied. Preliminary experimental investigations have been designed and prepared at Korea Atomic Energy Research Institute to develop a measurement of tritium concentration and correlation of bubble diameter for stripping gases in the liquid breeder. An acryl vessel and a stainless chamber were manufactured to observe bubble behavior and to measure bubble size, respectively, with a photography method, and the experimental investigations will be performed in the near future. An annular capsule and a plate type made with very thin membrane walls with porous structure inside were developed to improve response time and operational capability for high pressure conditions, and a permeation sensor test device was manufactured to evaluate the proposed permeation sensors. The hydrogen extraction column has been constructed based on the conceptual design for the preliminary investigations, and the fundamental liquid breeding experiments are planned to obtain various experiences on the hydrogen extraction technology.
