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.

Dr. Christopher Poresky is the Manager of Cyber Physical Systems (CPS) in the Instrumentation, Controls, & Electrical (IC&E) Department at Kairos Power. The CPS team designs and maintains Kairos human-machine interfaces, datalogging and communications infrastructure, and operations and maintenance strategies for Kairos test systems big and small including the Kairos Power Fluoride-Salt-Cooled High-Temperature Reactor (KP-FHR) design. These products empower the Kairos team to learn from its design, build, and test activities in real time and feed learnings into next iterations so that the KP-FHR can provide clean, affordable energy.
Previously, Dr. Poresky was a postdoctoral researcher at the University of California, Berkeley. He obtained a Ph.D. and M.S. in Nuclear Engineering from the University of California, Berkeley as well as a B.S. in Mechanical Engineering from Rutgers, the State University of New Jersey – New Brunswick.
