Julie G Ezold

Radioisotope Production and Operations Section Head

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. 

Previously, Ms. Ezold was the Californium-252 Program Manager and responsible for the technical aspects as well as the program management activities of each curium target campaign. Typical campaign activities include target fabrication, target approval for insertion into the High Flux Isotope Reactor, chemical processing of irradiated targets, and final source fabrication. Campaign products include, but are not limited to Californium-252, Berkelium-249, Einsteinium-253, and other trans-curium products. These trans-curium products have recently been used in the discovery of a new element, Tennessine (Element 117). In addition to her responsibilities as the Californium Program Manager, Ms. Ezold was responsible for planning and overseeing nuclear material processing R&D work safely and effectively for other nuclear isotopes such as: Nickel-63, Selenium-75, Iridium-192, and Neptunium-237.

Ms. Ezold actively supports nuclear science educational activities through the Nuclear Science and Engineering Directorate’s Educational Outreach Committee, K-2 Science Club, Mentor Program, and others.

Ms. Ezold holds a BS, 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.
