Job Summary:* SMSI is seeking a Nuclear Mechanical Engineer to work onsite in Oak Ridge, TN. The candidate must have 10 or more years working at an operating nuclear reactor with engineering experience including but not limited to engineering design and manufacturing practice including welding and joining techniques combined with a sound understanding of machine design. Responsibilities/ Abilities: The candidate will work on major replacement projects, the reactor pressure vessel and the beryllium reflector, to sustain and enhance HFIR's operation performance. Both projects require engineering, design, and analysis supports to compliment the integrated project team to deliver the design milestones on schedule and within scope. Specifically, the individual will be working closely with system engineers, designers, and various other disciplines within RRD. This position will be assigned to the HFIR Upgrades Project Office and interacts with personnel at all levels within the HFIR. Operating at 85 MW, High Flux Isotope Reactor (HFIR) is the highest flux reactor-based source of neutrons for research in the United States, and it provides one of the highest steady-state neutron fluxes of any research reactor in the world. The thermal and cold neutrons produced by HFIR are used to study physics, chemistry, materials science, engineering, and biology. Requirements: 10 or more years working at an operating nuclear reactor with engineering experience including but not limited to engineering design and manufacturing practice including welding and joining techniques combined with a sound understanding of machine design.
