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.

Gas tagging consists of adding small amounts of gas with a unique isotopic composition for each assembly to nuclear reactor fuel and control assemblies. During subsequent irradiation, when any pin of an assembly fails, the tag gas released along with other gas from the pin plenum enables location of the defective assembly by a mass spectrometric analysis of a sample of the reactor cover gas. The general procedure presented for the design of a gas tag system has been used to produce three designs for the gas ratios for Cores I through IV of the Fast Flux Test Facility. The designs are compared with and without “age tagging,” the use of information from tag gas burnup to help discriminate between failures of different assemblies. A few comments included on the operation of a gas tag system help ensure that the system will operate within the assumptions made in the design of the gas tag ratios.
