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.

Christmas Night
Twas the night before Christmas when all through the houseNo electrons were flowing through even my mouse.
All devices were plugged in by the chimney with careWith the hope that St. Nikola Tesla would share.

The criticality eigenvalue problems of both multigroup diffusion and transport theories have slow rates of convergence when the dominance ratio is close to one. This situation arises especially in the analysis of loosely coupled reactor systems and necessitates the use of acceleration techniques. The coarse mesh rebalance method constitutes one of the prominent ones of such acceleration schemes. The coarse mesh rebalance method has been used in the acceleration of direct diffusion criticality eigenvalue problems. In this study, this acceleration method is utilized also in the solution of adjoint diffusion problems in spherical geometry. The efficiency of the acceleration method is assessed through numerical experiments and certain conclusions have been drawn regarding the use of coarse mesh rebalance in such problems.
