Associate Radiochemist

Date: Jun 19, 2022

Location: Oak Ridge, TN, US, 37831

Company: Oak Ridge National Laboratory

Requisition Id 8082 


Oak Ridge National Laboratory (ORNL) is seeking an associate research and development staff scientist for our world class radiochemistry program. 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 Safety Administration. This position will grant you the opportunity to work with rare nuclear materials as part of both established and emerging radioisotope production programs, as well as advance development of novel separations, analytical techniques, and isotope applications.


This position resides within the Radioisotope Research and Development Section of Radioisotope Science and Technology Division (RSTD). The highly accomplished staff within the RSTD use the unique facilities at ORNL, including the High Flux Isotope Reactor (HFIR) and the Radiochemical Engineering Development Center (REDC), to 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.


Major Duties and Responsibilities:

  • Conduct research and development activities in both fundamental and applied science, with the aim to enable new radioisotope availability, increase efficiency of production, reveal previously undiscovered properties of radioisotopes, and discover novel applications. This includes both submission of proposals for competitively funded research, as well as leading sponsor-directed research.
  • With the support of senior research and technical staff, develop processing work plans for the separation, purification, and preparation of radioisotope products.
  • Interact effectively with technical and operations staff to safely execute work within a highly regulated facility.
  • Carry out hands-on radiochemical processing in a benchtop, fume hood, or glove box environment.
  • Manage laboratory spaces, including overseeing chemical inventory and equipment hazards analysis.
  • Provide imaginative, thorough solutions to a wide range of complex, ambiguous, and/or difficult problems.
  • Publish results in peer reviewed journals and internal manuscripts.
  • Serve in professional societies and standards development committees
  • As a member of the ORNL scientific community, you will be expected to commit to ORNL's Research Code of Conduct. Our full code of conduct, and a statement by the Lab Director's office can be found here:


Basic Qualifications:

  • Ph.D. in in chemistry, chemical engineering, nuclear engineering, or a related field, and two years of relevant experience.
  • Demonstrated work experience with radiological materials, including knowledge of ALARA principles and appropriate radiological work controls.
  • Excellent communication skills, including verbal, presentation, and writing skills, as well as the ability to work within a multidisciplinary environment
  • Demonstrated experience in at least one of the following technical areas
    • Hands on synthesis and characterization of small organic compounds (e.g., nmr, uv-vis-nir)
    • Metal extraction capabilities using liquid-liquid and solid-liquid separation systems
    • Solid state characterization of actinide materials
    • F-element chemistry
    • Automated chemistry separations
    • High Pressure Ion Chromatography
    • Radioactive gas trapping and recovery


 Preferred Qualifications:

  • Experience with a wide range of analytical techniques.
  • Experience with a wide range of chemical separations.
  • Experience writing proposals and soliciting funding for research and development activities.
