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.

The main objective of this work is to see the feasibility of using an electrochemical ion-exchange process in line with decontamination for removal of radioactive metal ions from simulated decontaminated solution/metal ion–loaded cation-exchange resin. This could extend the service period of resin, and the volume of radioactive resin (organic) waste generation could be minimized. Simulated decontamination solutions/spent resins were used in the middle section of a three-compartment cell separated by cation-permeable Nafion membranes. Metal ions from this central compartment permeated through the membrane and got deposited on the cathode by application of potential. Process parameters like applied voltage, interelectrode distance, pH, decontamination formulations, and type of membrane were optimized for efficient transport of metal ions. The resin life was observed to be extended by 5 h by an electrochemical regeneration process with Nafion membrane N115. The transport process, as monitored by the change in metal ion concentration in the cathodic compartment, was observed to pass through a maximum. Maximum metal ion removal was observed with formic acid/formate formulation indicating that the presence of acidity in the anodic compartment has a synergistic effect on the transport process. The cathodic compartment deposit was characterized by X-ray diffraction, laser Raman spectroscopy, scanning electron microscopy, and energy dispersive X-ray analysis.
