The technical structure of AVS is organized as a matrix. Members can participate in one or more Divisions or Technical Groups, each of which is focused around a major topical area. Members may also participate in Chapters and Student Chapters, which are regional organizations that focus on local area needs.

Heavy Actinide Production Program at Oak Ridge National Laboratory

Julie G. Ezold, Radioisotope Production and Operations Section Head
Oak Ridge National Laboratory

For more than 50 years, Oak Ridge National Laboratory’s (ORNL) unique research facilities and staff have provided the research community with heavy actinides through fermium (257Fm). ORNL’s facilities, the Radiochemical Engineering Development Center and the High Flux Isotope Reactor, are truly one-of-a-kind for the production of heavy actinides. All aspects of the reactor-produced heavy actinides will be addressed: fabrication of curium targets, irradiation, radiochemical separations and purification processing. Research activities for new production and separations techniques are being pursued at ORNL and will include novel irradiation schemes and shielding materials for berkelium and einsteinium production. To improve separations, replacement of the CLEANEX (HDEHP extraction) and the LiCl anion exchange processes are being investigated. Another focus area is the separation of americium from curium to enhance the quality of the current feedstocks for heavy actinide production.

Ms. Ezold has over 25 years’ experience in the nuclear sciences and is currently the Radioisotope Production and Operations Section Head.  She is responsible for managing the Bethel Valley Radiochemical Processing, Melton Valley Radiochemical Processing, and the Technical Services, Finishing, and Dispensing Groups that form the section.  This section has responsibility for performing and optimizing the production of all radioisotopes that are in a continuing and sustained state of demand and production beyond the research and development phases.  This includes major radioisotope production efforts ≥$10M/year in scope as well all other ongoing or campaigned radioisotope production activities at ORNL.

Ms. Ezold holds a B.S., Nuclear Engineering from Rensselaer Polytechnic Institute (1990) and a Masters, Nuclear Engineering, from North Carolina State University (1992).  Her master’s research was conducted at the High Flux Isotope Reactor at ORNL.  After completing her master’s, she joined the staff at ORNL and has held positions in engineering, waste management, criticality safety, and isotope production.

The society has very reasonable student rates of $40 per year. If you would like to join the AVS, please visit the membership page for more information.
