AbstractThere is significant interest in reducing the timeline for post detonation nuclear debris examination. A critical need is rapid dissolution of refractory nuclear debris to facilitate measurement of key radioisotopes and isotope ratios. Field deployable, rapid dissolution and analysis methods could significantly shorten the attribution analysis timeline. The current practice uses HF in combination with other acids to attack silicates and other refractory minerals expected in debris samples. However, techniques requiring HF are not amenable to use in the field. The fluorinating agent ammonium bifluoride (ABF) is a potential field deployable substitute for HF. In this work we report on the use of in-direct sonication with ABF as a means to improve low-temperature acid digestion of seven USGS and NIST geological reference materials. Using this method, elemental recoveries for USGS reference materials DNC-1a Dolerite, QLO-1a Quartz Latite, SDC-1 Mica Schist, and BHVO-2 Hawaiian Basalt were quantitative while the recovery of elements in USGS AGV-2 Andesite and NIST SRM 278 Obsidian and 1413 High Alumina Sand were low.

Abstract Nuclear forensic analysis of uranium oxide fuel pellets and the respective data interpretation have proven to be important elements of the investigative process when such material is found out of regulatory control. Uranium oxide fuel pellets are produced at industrial scale and have to meet tight technical specifications. Variations in the production process of different manufacturers or fuel fabrication facilities offer an additional source of information. The compilation of such information in a nuclear materials database has proven to be a highly valuable resource. In consequence, measureable material properties (referred to as “signatures”) such as the isotopic composition, the physical dimensions, the chemical impurities, the products of the radioactive decay of uranium and the microstructure allow establishing the processing history of the material. To this end, dedicated analytical methods have to be developed and suitable methods for data evaluation and interpretation need to be utilised. The successful application of these nuclear forensic tools is illustrated with two case studies on real incidents of illicit nuclear trafficking of uranium oxide fuel pellets.
