As a U.S. Department of Energy (DOE) Office of Science national laboratory, ORNL has an extraordinary 80-year history of solving the nation’s biggest problems. We have a dedicated and creative staff of over 6,000 people! Our vision for diversity, equity, inclusion, and accessibility (DEIA) is to cultivate an environment and practices that foster diversity in ideas and in the people across the organization, as well as to ensure ORNL is recognized as a workplace of choice. These elements are critical for enabling the execution of ORNL’s broader mission to accelerate scientific discoveries and their translation into energy, environment, and security solutions for the nation.  



The Advanced Engineering Technologies (AET) Group is seeking a dedicated Nuclear Fuel Cycle Chemical Engineer to support our organization. The position will involve system architecture, design, implementation, and testing including hands on work in a research and development atmosphere. Projects will target development of lab scale to pilot plant sized nuclear fuel cycle unit operations and processes. This position is a mixed role where our new hire is expected to participate in design and testing of unique unit operations.  AET resides within the Nuclear Nonproliferation Division (NND) at Oak Ridge National Laboratory (ORNL).


The NND is a division operating within the National Security Sciences Directorate. NND staff supplies world class research, technology development, risk assessment, and systems analysis related to nonproliferation and counterproliferation. The division activities play a vital role in implementation of national policy issues that strive to ensure global nuclear security.  One of the major focus areas of ORNL's AET group is development of sophisticated approaches to operation, characterization, and analysis of nuclear processes. The group specializes in the application of engineering principles supporting the characterization of processes and related materials. The AET group collaborates and works with staff from other groups within NND and ORNL to assure the full expertise of fuel cycle processes are applied to meet sponsor needs.
