MFC Reactor Engineering for Digital Thread Intern - Summer 2027

Idaho National Laboratory•Idaho Falls, ID
•Onsite

About The Position

Reporting to a Senior Manager within MFC Reactor Engineering, the intern will support nuclear reactor modeling and development of a digital thread connecting reactor analyses across multiple physics and engineering domains. The work includes developing automated workflows and data pipelines that connect neutronics, thermal-hydraulic, structural, and multiphysics simulations to improve traceability and efficiency throughout the reactor design and analysis lifecycle. The intern will develop Python-based tools for automation, data management, visualization, and model integration; support reactor simulations; and explore the use of artificial intelligence to enhance coding productivity and analysis workflows. The role is intended for a candidate interested in combining nuclear engineering, advanced modeling and simulation, software development, and digital engineering to create integrated analysis frameworks that support next-generation reactor design and decision-making. The team works a 9x80 schedule onsite at the Idaho Falls campus. Internship start date and duration vary based on project and student availability. Course credit may be available if approved by the student's university. Interns are placed at the appropriate level based on degree field and level of education.
