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.

The Special Power Excursion Reactor Test III (SPERT III) was a series of reactivity insertion experiments conducted in the 1950s. This paper describes the validation of the U.S. NRC coupled code system TRITON/PARCS/TRACE to simulate reactivity insertion accidents (RIA) using several of the SPERT III tests. The NRC coupled code system was used to perform the SPERT III E-Core configuration tests in which the RIA was initiated by the rapid ejection of a central cruciform control rod. The resulting superprompt reactivity excursion and negative Doppler reactivity feedback produced the familiar bell-shaped power increase and decrease. The energy deposition during such a power excursion has important safety consequences, and the SPERT III tests provide a validation basis for the NRC coupled multiphysics codes. The models were developed using the original experiment documentation, and the results of five separate tests were used to validate the TRITON/PARCS/TRACE coupled code system.
