Advanced Nuclear Reactor and Fuel Cycle Engineer

Position: Advanced Nuclear Reactor and Fuel Cycle Engineer (Staff)
Requisition  Overview:  Oak Ridge National Laboratory (ORNL) is the largest US Department of Energy science and energy laboratory, conducting basic and applied research to deliver transformative solutions to compelling problems in energy and security. Our diverse capabilities span a broad range of scientific and engineering disciplines, enabling the laboratory to explore fundamental science challenges and conduct the research needed to accelerate the delivery of solutions to the marketplace.

The Reactor and Nuclear Fuel Cycle Analysis Group (RNFCA) Group is seeking candidates to apply for the Advanced Nuclear Reactor and Fuel Cycle Engineer (Staff) role. This role is responsible for working with state-of-the-art modeling and simulation capabilities for lattice physics, reactor core, spent fuel, and fuel cycle applications through leadership in the development and analysis of SCALE and/or the Virtual Environment for Reactor Applications (VERA) simulations and in collaboration with industry, national laboratories and university researchers.

ORNL has world-leading nuclear, radiological and scientific facilities, including the High Flux Isotope Reactor, and this role would support the neutronics and thermal-hydraulics analysis.

Major

Duties and Responsibilities:

Design, develop, optimize and analyze reactor models using world-class modeling and simulation codes (SCALE, VERA, OpenMC, MCNP, Serpent, MOOSE) to support the design and development of next generation nuclear reactors.

Develop and analyze fuel cycle models using Cyclus to evaluate advanced fuel cycle strategies to support the design and deployment of advanced nuclear reactors.

Interact effectively across organization structures with staff scientists and engineers and be an effective representative of ORNL and their research to sponsors and the professional community.

Conduct work on scope and on budget.

Communicate effectively the work performed through journal articles, presentations, reports, and code documentation.

Serve as a role model for integrity and safety in the conduct of research, mentoring of early career staff, and engagement with scientific and professional societies

Develop and submit funding proposals to DOE and other government agencies for new research efforts.

Deliver ORNL’s mission by aligning behaviors, priorities, and interactions with our core values of Impact, Integrity, Teamwork, Safety, and Service. Promote equal opportunity by fostering a respectful workplace – in how we treat one another, work together, and measure success.

Basic Qualifications:

PhD in nuclear engineering or closely related field and 2-5 years of post graduate experience.

Knowledge of nuclear reactor analysis R&D is required as demonstrated through research and associated publications.

Experience using SCALE, VERA, MCNP, Serpent, OpenMC, and/or MOOSE and familiarity with reactor systems and concepts.

Programming/scripting experience including the use of one or more of C/C++, Python, Fortran, Git, and CMake an asset.

Demonstrated writing and communication skills and ability to publish.

Preferred Qualifications:

Experience with Multiphysics software and simulations an asset.

Previous experience with the development and implement numerical algorithms in advanced modeling and simulation software related to reactor physics analysis an asset

Knowledge of software engineering best practices, including continuous integration, requirements management, and object-oriented programming concepts and design patterns an asset.

Experience working within a rigorous quality assurance program.

Ability to obtain a security clearance.
