Requisition Id 13984
Overview:
The Reactor Analysis and Modeling (RAM) Group within the Nuclear Safety and Experiment Analysis (NSEA) Section of the Research Reactors Division (RRD), Neutron Sciences Directorate (NScD) is hiring a Thermal Hydraulics Engineering Analyst for the High Flux Isotope Reactor (HFIR) at Oak Ridge National Laboratory. HFIR, one of the most powerful reactors in the world, supports neutron scattering, isotope production, and fuels and materials irradiation experiments.
We seek a motivated reactor analyst with expertise in nuclear heat transfer, fluid dynamics, and technical uncertainties related to fuel manufacturing, material properties, and operational variables. In this role, you will provide engineering and analytical support to address operational challenges, update legacy thermal-hydraulic analyses, and contribute to long-term projects like the HFIR Low-Enriched Uranium (LEU) conversion program. This role involves collaborating across multidisciplinary teams and cultural backgrounds within and outside the organization.
Major Duties/Responsibilities:
-
Perform high-quality reactor modeling, simulation, and thermal-hydraulic (T-H) analyses to support the HFIR safety basis, operational issues, and long-term upgrade projects.
-
Collaboratively work with other Nuclear Safety and Experiments staff; others within RRD (e.g., Systems Engineering, Operations); and other ORNL directorates and divisions to support RRD and ORNL T-H safety missions, as needed.
-
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: https://www.ornl.gov/content/research-integrity
-
Deliver ORNL’s mission by aligning behaviors, priorities, and interactions with our core values of Impact, Integrity, Teamwork, Safety, and Service. Promote diversity, equity, inclusion, and accessibility by encouraging a respectful workplace – in how we treat one another, work together, and measure success.
Basic Qualifications:
-
Engineering degree must be within nuclear engineering, mechanical engineering, chemical engineering, engineering physics, or equivalent. Engineering technology degrees are not considered equivalent.
-
Strong reactor analysis background in thermal hydraulics, as proven through university research, publications, and/or work experience.
Preferred Qualifications:
-
Experience modeling and analyzing sophisticated engineering systems with both analytical approaches and with software, such as COMSOL, ANSYS, RELAP5, TRACE, etc.
-
Experience and knowledge of the multi-physics reactor engineering framework, including the interplay between reactor neutronics, thermal-hydraulics, thermal-structural interaction, fluid-structure interaction, fluid dynamics, fluid transient analysis, material property variations, and accident analysis
-
Experience with LINUX or LINUX-like environments and scripting/computer languages, such as MATLAB, Python, and Fortran
Special Requirements:
-
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.
