Combined Radiation Detection Methods For Assay Of Higher Actinides In Separations Processes: Quarterly Progress Report: January-March 2006, Denis Beller, Warnick Kernan
Combined Radiation Detection Methods For Assay Of Higher Actinides In Separations Processes: Quarterly Progress Report: January-March 2006, Denis Beller, Warnick Kernan
Safeguards Campaign (TRP)
Monitoring of higher actinides (HA--includes neptunium, plutonium, americium, and curium) during the separation of used nuclear fuel has been identified as a critical research area in the U.S. Advanced Fuel Cycle Initiative (AFCI). Recycling of used fuel by chemically separating it into uranium, fission products, and HA would be the first step in this new fuel cycle. The Material Protection, Accounting, and Control (MPAC) are necessary for materials accounting, criticality monitoring, and assurance of proliferation resistance. The objective of the MPAC project is to develop technology to detect and accurately measure quantities of higher actinides in used fuel assemblies and …

Safeguards Campaign (TRP)
The ultimate objective of this project is to develop technology to detect and accurately measure quantities of higher actinides in processing systems without taking frequent samples. These systems include used fuel receipt, separations batches, and pipelines. A variety of measurements may be combined to calculate flow rates of actinide elements with a to-be-determined precision. Nuclear and decay characteristics of materials during processing will be acquired, conceptual designs of monitoring systems will be developed, radiation transport studies will be conducted to develop an understanding of operational regimes, and experiments will be performed to confirm performance. Radiation transport and scoping studies will …
