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 v. Texas: Supreme Court weighs challenge to NRC authority in spent fuel storage case
The State of Texas has not one but two ongoing federal court challenges to the Nuclear Regulatory Commission that could, if successful, turn decades of NRC regulations, precedent, and case law on its head.

For in-pile sweep-gas experiments it is sometimes necessary to deduce the time-dependent release rate of a radioactive gas from a specimen by measurements made at some point downstream. An experimental method to measure the amount of dispersion of the radioactive gas in the sweep gas is described. By this method, correction factors can be applied to a measured wave shape to obtain the generated wave shape. A theoretical model, assuming axial turbulent flow of the sweep gas with a flat radial distribution, has been developed. Application of the model involves an experimentally determined parameter “a” for the particular sweep-gas system used. The agreement between the experiment and the theoretical model is excellent.
