Requisition Id 8093 


Oak Ridge National Laboratory (ORNL) is seeking Senior Laboratory Technicians focused on production, handling, chemical manipulations, and packaging of a variety of nuclear materials, as well as performing material handling equipment setup, troubleshooting, and acceptance testing within remote operations environments


You will support the largest radioisotope production and research portfolio within the Department of Energy (DOE) Office of Science for Isotope R&D and Production, as well as extensive isotope production programs for the DOE Office of Nuclear Energy and National Nuclear Security Administration, this position will grant you the opportunity to work with rare nuclear materials, and the unique facilities at ORNL, including the High Flux Isotope Reactor (HFIR) and the Radiochemical Engineering Development Center (REDC).


This position resides in the Radioisotope Science and Technology Division (RSTD) at ORNL. The esteemed staff of the RSTD produce a variety of important medical, scientific, and industrial radioisotopes. These include several alpha/beta emitting radioisotopes either deployed or under clinical trial for treatment of cancer (e.g., Ac-225, Ac-227, Ra-224/Pb-212, and W-188); heavy actinides Bk-249, Es-254, and Fm-257 for fundamental chemistry research and new element discovery; Cf-252 for neutron emitting applications; Pu-238 for space exploration; and Ni-63 and Pm-147 for industrial applications.


As a senior laboratory technician, you will become a technical leader of one or more laboratory processes, you will be involved in the processing of nuclear materials for the purposes of supplying radioisotope products and supporting development new radioisotope products for the international scientific community. This includes activities such as material dissolutions, chemical separations, evaporations, pressing of solid compounds, material analysis, and characterization. These operations are performed with radioactive materials within hot cells, shielded caves, and glove boxes at REDC and other facilities. The work is performed under exacting quality specifications and with adherence to conduct of operations in nuclear facilities, requiring good team dynamics and efficiency to meet tight schedules. We are seeking a team member who can be a team player with excellent attention to detail.
