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.

Direct waste transfer process quickens at Savannah River Site
The Department of Energy Office of Environmental Management’s liquid waste contractor at the Savannah River Site this month marked the first direct transfer of decontaminated waste from the Salt Waste Processing Facility (SWPF) to the Saltstone Production Facility (SPF). This is a new step in optimizing waste processing, according to the DOE.

A polarization reversal of an electromagnetic wave relating to electron cyclotron resonance in an inhomogeneously magnetized plasma-filled waveguide is investigated by using a one-dimensional code of full wave analysis with cold plasma approximation, and its results are compared with the experimentally observed polarization reversal, which has already been reported [Phys. Rev. Lett., 94, 215001 (2005)]. It is found that the polarization reversal can be reproduced by this code and its results are in good agreement with the experimental ones. The polarization-reversal position is affected by a wavenumber perpendicular to the magnetic-field lines, which is determined by the radial boundary condition between the plasma column and the peripheral vacuum layer in our experiments.
