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.

In concrete reactor vessels of high temperature reactors many cavities with different diameters are arranged. The design of the closures for such cavities is an important problem in the detail engineering. A draft based on using prestressed concrete as a material is presented for closures with high diameter values. The problems that could possibly be caused by the concrete weight might be solved through a proposal based on a separation of the closure into an inner and outer part. A special view is given to the kind of production as well as to a rapid mounting and remounting of the closures and sealing problems. The closures are fixed on the reactor vessel by tendons. The influence of the tendon forces, creep and shrinkage, pressure, etc. on stresses, stress distribution, and deformation are proved by a finite element analysis and the results are pointed out. A short outlook of further development is given.
