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.

NRC updating GEIS rule for new nuclear technology
The Nuclear Regulatory Agency is issuing a proposed generic environmental impact statement (GEIS) for use in reviewing applications for new nuclear reactors.
In an April 17 memo, NRC secretary Carrie Safford wrote that the commission approved NRC staff’s recommendation to publish in the Federal Register a proposed rule amending 10 CFR Part 51, “Environmental Protection Regulations for Domestic Licensing and Related Regulatory Functions.”

We evaluated electrolytic separation factors of hydrogen isotopes by SPE (Solid Polymer Electrolyte) for application to environmental tritium analysis. The apparent separation factors a for deuterium and a for tritium were determined as 3.5 ± 0.1 and 6.2 ± 0.5, respectively. The tritium enrichment of 8.4 times was achieved, when a 1000 ml of sample water was electrolyzed to about 60 ml. The chemical composition changes before and after the electrolysis were examined, showing an increase in H+ and Na+ concentrations and a decrease in Mg2+ and Ca2+concentrations. F-, which was not contained in the sample water, was detected after electrolysis accompanying with a reduction of SO42-, Cl- and NO3-. The memory of tritium and ions in the electrolysis cell after electrolysis was possible to be eliminated by washings with de-ionized water. Tritium concentrations of rain at Kumamoto, Japan were determined with a combination of the present electrolytic enrichment system and liquid scintillation counting.
