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.

Feinstein Institutes to research novel radiation countermeasure
The Feinstein Institutes for Medical Research, home of the research institutes of New York’s Northwell Health, announced it has received a five-year, $2.9 million grant from the National Institutes of Health to investigate the potential of human ghrelin, a naturally occurring hormone, as a medical countermeasure against radiation-induced gastrointestinal syndrome (GI-ARS).

Through-diffusion experiments of some sorbing nuclides onto granodiorite have been carried out to understand their diffusion and sorption characteristics. A newly designed experimental setup with compacted structure and dimensions was used for the through-diffusion process. The nuclides used in the experiment were tritiated water (HTO), Sr, Cs, Ni, Nb, and Am. The diffused nuclides were sampled at certain periods of time to estimate the diffusivities. After the diffusion experiment was carried out for 1.5 years, the rock media were recovered. In addition, a sequential chemical extraction was conducted to estimate the sorption types of the nuclides for the recovered rock disks. The relationship between diffusion and sorption was investigated from the viewpoint of sorption reversibility. The measured diffusivity was compared to the other experimental results.
