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.

WIPP’s SSCVS: A breath of fresh air
This spring, the Department of Energy’s Office of Environmental Management announced that it had achieved a major milestone by completing commissioning of the Safety Significant Confinement Ventilation System (SSCVS) facility—a new, state-of-the-art, large-scale ventilation system at the Waste Isolation Pilot Plant, the DOE’s geologic repository for defense-related transuranic (TRU) waste in New Mexico.

Two assemblies of self-powered in-core detectors have been tested in the Oconee 2 pressurized water reactor for more than 1 yr. The assemblies contain both prompt-responding hafnium and delayed-responding rhodium detectors. Four hafnium detectors are paired with four rhodium detectors in each assembly. The purpose of the experiment is to define the characteristics of the prompt and delayed detectors operating together in pairs. Data from the experiment show that the prompt detectors need to be calibrated on-line and that the rhodium detectors paired with them can be used to make the calibrations. The response of the hafnium detector to a reactor scram is given.
