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.

Korea has developed a liquid breeder blanket and participated in the test blanket module program for ITER. To develop liquid breeder technologies with not only liquid lithium but also lead-lithium (PbLi), an experimental loop for the liquid breeder was constructed at the Korea Atomic Energy Research Institute. The main purposes of the loop are developing components such as an electromagnetic pump, testing the effects of magnetohydrodynamics, and investigating the compatibility between the liquid breeder and other materials. Before operating the loop, the melting and solidifying temperatures of the PbLi and its contamination were experimentally investigated considering cyclic use with the prepared reaction chamber. Melting and solidifying temperatures were [approximately]235°C, and there was no change even with the cyclic test. Because of contamination such as oxidation, however, the composition of PbLi can be changed, which should be considered when operating the loop. The reactions of PbLi and Li with air and water were observed. The PbLi did not react with air or water, but Li showed a severe reaction with them. However, reaction mitigation using nano-particles was found in the experiment.
