Chemical Engineer

Date: Nov 14, 2022

Location: Oak Ridge, TN, US, 37830

Company: Oak Ridge National Laboratory

Requisition Id 9491 


We are seeking Chemical Engineers who will focus on the development and support of a variety of research projects encompassing the front and back ends of the nuclear fuel cycle and related separation systems. Experience with chemical processing R&D equipment ranging in size from laboratory to engineering scales is highly desired. The candidate will be expected to work with other staff to develop process flowsheets and processing equipment designs. This position resides in the Fuel Cycle Chemical Technology Group in the Nuclear Energy and Fuel Cycle Division, Fusion and Fission Energy and Science Directorate at Oak Ridge National Laboratory (ORNL).


Major Duties/Responsibilities:

  • The successful candidate(s) will be expected to have a background in chemical process engineering, particularly material separations systems with an emphasis on chemical engineering separations techniques and mass transfer models associated with vapor-solid, vapor-liquid, and liquid-liquid systems.
  • The successful candidate(s) will be expected to know unit operations and design experience with process flow diagrams and P&IDs.
  • The successful candidate(s) may be responsible for conceptualizing and designing engineering test capabilities essential to ensuring the maintenance and expansion of domestic nuclear fuel cycle capabilities to address current and future needs in securing the nonproliferation of nuclear materials.
  • Efforts will focus on nuclear fuel cycle chemical processing, particularly chemical conversion and separations processes pertaining to the production of engineered forms of actinide compounds used throughout the uranium fuel cycle.
  • As part of design tasking, the successful candidate will be responsible for the preparation of design documents (equipment drawings and specifications) for tracking execution schedules and costs and for estimation of component procurement, installation, and operation costs.
  • Tasks will include the selection and configuration of appropriate equipment, preparation of an experiment and operating procedures, and preparation of training modules.
  • The successful candidate will be required to interact effectively with various personnel and sponsors, both within and outside of ORNL.


Basic Qualifications:

  • Ph.D.hD in Chemical Engineering with experience in uranium chemical processing or chemical research, including pilot-scale R&D, BS degree with 4+ years of experience, MS with 2+ years of similar experience.
  • A strong grasp of the fundamentals of chemical process unit operations with an emphasis on separations and chemical reaction science.
  • An understanding of fundamental chemical engineering thermodynamics.
  • The ability to work in chemical laboratory and processing environments with a high level of attention to detail and adherence to safe work practices that such activities demand.
  • Operational familiarity with uranium processing equipment at pilot or production scales.
  • The ability to conceive chemical process flowsheets and identify knowledge gaps for fuel cycles for the current fleet of reactors and advanced reactor technologies.


Preferred Qualifications:

  • Excellent interpersonal, presentation, and writing skills to enable effective interaction and communication with technical peers, program managers, and sponsors.
  • Organized, detail-oriented, and sensitized to a nuclear safety culture.
  • The successful candidate will ensure compliance with environment, safety, health, and quality program requirements
  • Motivated self-starter with the ability to work independently and to participate creatively in collaborative teams across the laboratory
  • Ability to function well in a fast-paced research environment, set priorities to accomplish multiple tasks within deadlines, and adapt to ever-changing needs


This position requires the ability to obtain and maintain a clearance from the Department of Energy. As such, this position is a Workplace Substance Abuse (WSAP) testing designated position. WSAP positions require passing a pre-placement drug test and participation in an ongoing random drug testing program.


This position will remain open for a minimum of 5 days after which it will close when a qualified candidate is identified and/or hired.
