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.

A diagnostic neutral beam (DNB) is used in the Tokamak Fusion Test Reactor (TFTR) to provide a time-modulated, spatially localized enhancement of the signal in the charge-exchange (CX) diagnostic. Two autonomous charge-exchange neutral analyzer (CENA) systems have been designed f or the TFTR. The first system measures the plasma ion temperature along as many as 12 vertical line-of-sight chords spaced approximately equidistantly across the torus minor diameter. The second system emphasizes the measurement of ion phenomena associated with neutral beam injection heating and has a fanlike field of view along six sightlines in the equatorial plane. The DNB is steerable in order to access the viewing field of either CENA system. The performance of the DNB is evaluated to determine the optimal beam parameters for active CX measurements. Using the optimal beam design parameters, the effectiveness of the neutral beam doping is examined for both CENA systems over the envisioned range of the plasma density and temperature in TFTR.
