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.

Discovering, Making, and Testing New Materials: SRNL’s Center For Hierarchical Waste Form Materials
Savannah River National Laboratory researchers are building on the laboratory’s legacy of using cutting-edge science to effectively immobilize nuclear waste in innovative ways. As part of the Center for Hierarchical Waste Form Materials, SRNL is leveraging its depth of experience in radiological waste management to explore new frontiers in the industry.

For measuring the tritium concentration in water, a water monitoring system was developed. The monitoring system consists of a flow-cell detector, a pair of photomultiplier tubes, a circuit unit (including a high-voltage power supply and a coincidence counting module), a water flow pump and a multichannel pulse height analyzer. The flow-cell detector was fabricated using granular CaF2(Eu), which was solid scintillation materials. The performance of the water monitoring system was examined with three water samples containing different tritium concentrations of 10, 50 and 100 Bq/ml, and linearity between the count rate and the tritium concentration was examined. The results suggest that our system reasonably works as a water monitor for measuring low level tritium concentration. This system is the first such real-time monitoring system able to measure tritium concentrations in water continuously flowing through the solid scintillation detector.
