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.

NWMO to select Canadian repository site this year
Canada’s Nuclear Waste Management Organization, a not-for-profit organization responsible for the long-term management of the country’s intermediate- and high-level radioactive waste, is set to select a site for a deep geologic repository by the end of the year.

We derive three new linear-discontinuous least-squares discretizations for the Sn equations in one-dimensional slab geometry. Standard least-squares methods are not compatible with discontinuous trial spaces, and they are also generally not conservative. Our new methods are unique in that they are based upon a least-squares minimization principle, use a discontinuous trial space, are conservative, and retain the structure of standard Sn spatial discretization schemes. To our knowledge, conservative least-squares spatial discretization schemes have not previously been developed for the Sn equations. We compare our new methods both theoretically and numerically to the linear-discontinuous Galerkin method and the lumped linear-discontinuous Galerkin method. We find that one of our schemes is clearly superior to the other two and offers certain advantages over both of the Galerkin schemes.
