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.

The partial differential diffusion-kinetic equations describing the diffusion and reaction of chemically active species along the tracks of ionizing radiation are discussed. The few limiting cases of these equations that possess exact analytic solutions form the basis for a general expansion of the probability densities of reactive species in terms of time-dependent Gaussian distribution functions. In this expansion, the familiar prescribed diffusion hypothesis of Samuel and Magee appears as the first-order approximation. The convergence of the expansion technique and its applicability to multiradical reaction mechanisms are illustrated by means of example calculations. One of the chief advantages of the method introduced is that it allows the work of Ganguly and Magee on overlapping spherical spurs to be extended to multiradical models.
