Radiochemical Process Engineer

Date: Sep 20, 2022

Location: Oak Ridge, TN, US, 37830

Company: Oak Ridge National Laboratory

Requisition Id 8114 


Oak Ridge National Laboratory (ORNL) is seeking a radiochemical process engineer for our world class radioisotope production program. Supporting 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 ensure the safe and effective execution of nuclear materials processing.


This position resides in the Process Coordination Group (PCG) within the Radioisotope Science and Technology Division (RSTD) of the Isotope Science and Engineering Directorate (ISED) at Oak Ridge National Laboratory (ORNL). 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 emitting radioisotopes either deployed or under clinical trial for treatment of cancer (e.g., Ac-225, Ac-227); heavy actinides Bk-249, Es-254, and Fm-257 for fundamental chemistry research and new element discovery; Cf-252 for neutron emitting applications; and Pu-238 for space explortation. The bulk of the work carried out by the PCG resides in the REDC, a category two nuclear facility, and is performed within heavily shielded processing hot cells.


Major Duties and Responsibilities:

  • Working closely with the radioisotope research and development section, develop practical processing plans and material movement logistics.
  • Track the progress of radioisotope processing, including tank levels and nuclear material inventory.
  • Interpret analytical measurements and perform calculations to determine the contents of material batches.
  • Work to create a production and reliability focused environment, so that ORNL can be successful in meeting our mission to supply critical nuclear materials for science, medicine, and industry, that no one else can.
  • Assess the readiness of processing tasks for transition from research and development to processing and manufacturing.
  • Support opportunities for process improvement to increase utilization of facilities.
  • Provide imaginative, thorough engineering solutions to a wide range of complex, ambiguous, and/or difficult problems.
  • Implement continuous improvement and ensure work is completed to the safety, security, and quality standards of a national laboratory.
  • Maintain detailed records relating to nuclear materials processing
  • 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:

  • A Bachelor of Science Chemical Engineering, Nuclear Engineering, Chemistry, or similar field and of 2 years of related experience is required. Work towards an advanced degree with practical research or internship experience can be applied towards this experience requirement.
  • Strong communication skills, including technical writing

Preferred Qualifications:

  • Experience with the analysis of radiochemical data
  • Experience with the execution of manufacturing scale chemical processing.
  • Experience in developing material process flow sheets
  • Experience translating research and development processes into reliable operations
  • Experience in maintaining high levels of process documentation and quality control and assurance


Special Requirements


Export control, clearance: Successful candidates must be eligible for a L security clearance.
