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.

China is charged with around 7.5% of the ITER toroidal field (TF) conductor fabrication. In total about 6000 km of Nb3Sn strands need to be supplied for Chinese Domestic Agency (CNDA), and now the TF procurement arrangement (PA) for CNDA is in the last phase, i.e., production. According to the PA, the Domestic Agency (DA) has to verify on a regular basis the room and low temperature measurements carried out by the strand suppliers. The verifications shall be performed by the reference laboratories on the strand verification samples adjacent to the samples used by the strand suppliers for critical current measurements. As the reference laboratory of CNDA, the superconducting strand test laboratory of Institute of Plasma Physics Chinese Academy of Sciences (ASIPP) is undertaking the task of Nb3Sn strand verification. The verifications include diameter, chromium plating thickness, twist pitch direction and length, copper-to-non-copper volume ratio, residual resistance ratio (RRR), critical current (IC) and resistive transition index (n), and hysteresis loss. The verification level was based on the requirements of the ITER PA. From the results, the supplied strands for the TF conductors fulfill well the requirements of the ITER PA.
