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.

Remembering Charles E. Till
Charles E. Till
Charles E. Till, an ANS member since 1963 and Fellow since 1987, passed away on March 22 at the age of 89. He earned bachelor’s and master’s degrees from the University of Saskatchewan and a Ph.D. in nuclear engineering from Imperial College, University of London. Till initially worked for the Civilian Atomic Power Department of the Canadian General Electric Company, where he was the physicist in charge of the startup of the first prototype CANDU reactor in Canada.
Till joined Argonne National Laboratory in 1963 in the Applied Physics Division, where he worked as an experimentalist in the Fast Critical Experiments program. He then moved to additional positions of increasing responsibility, becoming division director in 1973. Under his leadership, the Applied Physics Division established itself as one of the elite reactor physics organizations in the world. Both the experimental (critical experiments and nuclear data measurements) and nuclear analysis methods work were internationally recognized. Till led Argonne’s participation in the International Nuclear Fuel Cycle Evaluation (INFCE), and he was the lead U.S. delegate to INFCE Working Group 5, Fast Breeders.

Cyclic voltammetry is one of the most common electroanalytical methods for determining the thermodynamic and electrochemical behavior of a species in the eutectic molten salt. The diffusion coefficient, apparent standard potential, transfer coefficient, equilibrium potential, and other parameters can be determined through this method. This study focused on a development of an interactive reverseengineering method by analyzing available uranium chloride data sets (1 to 10 wt%) in a LiCl-KCl molten salt at 773 K under different scan rates to help improve and provide robustness in detection analysis. A principle method and a computational code have been developed by using electrochemical fundamentals and coupling various variables, such as the diffusion coefficients, formal potentials, and process time duration. In addition, a graphical user interface (GUI) through the commercial software Matlab was created to provide a controllable environment for different users. Results provide plots of current, potential, and concentration of each species as a function of time under various determined conditions. The GUI also displays the reversible and irreversible peaks, in a very short run time (around 2 min), with an adequately selected time interval of approximately 0.08 s and an ability to calculate the concentration of each species (e.g., U4+ and U3+) at any specified conditions.
