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.

Argonne’s METL gears up to test more sodium fast reactor components
Argonne National Laboratory has successfully swapped out an aging cold trap in the sodium test loop called METL (Mechanisms Engineering Test Loop), the Department of Energy announced April 23. The upgrade is the first of its kind in the United States in more than 30 years, according to the DOE, and will help test components and operations for the sodium-cooled fast reactors being developed now.

Many of the ITER diagnostic systems will be mounted in the equatorial and upper ports of the torus, supported plugs support the diagnostics and provide functions of baking, cooling, and neutron shielding. They must operate reliably in the demanding ultra-high vacuum, high radiation environment of the ITER tokamak for many years.Recent work on the mechanical design of the equatorial port plugs is reported, including a proposal for a new conceptual design, which uses the lid of the port plug as a structural member. The design of a complex component like this is an iterative process considering the interaction of the features of the port plug structure, neutron shielding components and diagnostic components with the electromagnetic forces induced in the structure by plasma disruptions.These electromagnetic forces are recognised to dominate the requirements for the strength of the structure. Much work has been carried out on this topic by other people, but generally this has been based on models which make assumptions about the boundary conditions. An ANSYS electromagnetic model of a half-sector of ITER has now been developed by UKAEA, to study the induced forces in the equatorial port plugs.
