Gregory Dale is a Program Leader and R&D Engineer in the Advanced Electrodynamics Group in the Accelerator Operations and Technology Division. Dr. Dale received a BS in Nuclear Engineering from the University of New Mexico, a MS in Nuclear Engineering with a minor in Physics from North Carolina State University, and a PhD in Electrical Engineering from the University of Missouri-Columbia. Dr. Dale is currently the LANL program leader supporting the Global Threat Reduction Initiative’s (GTRI, NNSA NA-21) effort to accelerate the commercial domestic production of the medical radioisotope Mo-99 without the use of highly enriched uranium. Dr. Dale is also the project leader for the alternative neutron source for well-logging project at LANL. Dr. Dale is a member of the American Nuclear Society (ANS) and a Senior Member of the Institute of Electrical and Electronics Engineers (IEEE). Dr. Dale was the conference chair for the 2014 IEEE International Power Modulator and High Voltage Conference and serves on the executive committee of the ANS Accelerator Applications Division.

Current Engineering and Design Activities at Los Alamos National Laboratory Supporting Commercial U.S. Production of ⁹⁹Mo without the Use of HEU

Los Alamos National Laboratory (LANL) is supporting the commercial U.S. production of ⁹⁹Mo as part of the National Nuclear Security Administration (NNSA) Global Threat Reduction Initiative’s (GTRI) program to accelerate the establishment of a reliable domestic supply of this medical radioisotope without the use of highly enriched uranium (HEU). In partnership with several other national laboratories, we are currently providing engineering design and support to NorthStar Medical Radioisotopes and SHINE Medical Technologies as part of the GTRI program. The NorthStar technology uses an electron beam from an electron accelerator incident on enriched¹⁰⁰Mo targets to produce ⁹⁹Mo through the (γ,n) photonuclear reaction. The SHINE technology uses a subcritical accelerator-driven uranium solution to produce fission product ⁹⁹Mo. An overview of our engineering design support activities for these two technologies will be given.
