B A Tatum

Stable Isotope Portfolio Manager and Group Leader

Alan has been with ORNL 33 years, beginning in the Physics Division distributing control and electrical systems for the Oak Ridge Isochronous Cyclotron (ORIC) energy booster for heavy ion beams at the Holifield Heavy Ion Research Facility (HHIRF). He was a key member of the team that converted HHIRF into the Holifield Radioactive Ion Beam Facility (HRIBF), the first National User Facility for nuclear physics research with short-lived ion species. His accomplishments include design and implementation of the unique split-pole first stage mass separator, the high-voltage DC platform system, and control systems for the Injector for Radioactive Ion Species. Under his leadership, the Stable Isotope team received a 2018 DOE Appreciation Award for producing high assay Ru-96 in the first enrichment campaign with the ORNL-developed Electromagnetic Isotope Separator (EMIS), and also completed a first Gas Centrifuge Isotope Separator (GCIS) enrichment campaign for Mo-100.

Alan was Contractor Project Manager for the High Power Target Laboratory and the facility’s second radioactive ion beam injector, IRIS2, and later for a $27M HRIBF deactivation and decommissioning project, receiving a Department of Energy Appreciation Award. He became Stable Isotope Group leader in 2016 and Portfolio Manager in 2018. He serves as the Chief Engineer for the $250M U.S. Stable Isotope Production and Research Center (SIPRC) Project and as Chair of the ORNL Electrical Safety Committee.

Alan holds Bachelor of Science and Master of Science degrees in electrical engineering from Tennessee Technical University.
