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.

ARPA-E announces $40 million to develop transmutation technologies for UNF
The Department of Energy’s Advanced Research Projects Agency–Energy (ARPA-E) announced $40 million in funding to develop cutting-edge technologies to enable the transmutation of used nuclear fuel into less-radioactive substances. According to ARPA-E, the new initiative addresses one of the agency’s core goals as outlined by Congress: to provide transformative solutions to improve the management, cleanup, and disposal of radioactive waste and spent nuclear fuel.

In the tritium recovery processes, the microreactor is used for conversion of the various tritiated streams to water. Microreaction technology offers many advantages for chemical reactions, mainly a high surface-to-volume ratio, a well-defined residence time in the microchannels, and good thermal transport. Also, from an oxidation point of view, the microreactor is proven to be safer by comparison with a conventional oxidation reactor. Another major advantage is that the microreactor can be designed to provide a high recombination efficiency (more than 99.9%), if required. This paper aims to present the issues related to the design, calculation, and manufacturing of a high-efficiency microreactor that can be used to convert the tritiated streams to water.
