- Strong technical writing, communication, and engineering judgment.
- Eligibility to work in the United States without sponsorship. with molten-salt, inert-gas, vacuum, nuclear hot-cell, or fuel-cycle systems and with elevated-temperature or corrosion-resistant alloys. with ASME Section VIII Division 2, design-by-analysis, fatigue, buckling, creep, seismic qualification, or coupled thermal-mechanical analysis. with analysis tools such as CAESAR II, Auto PIPE, ANSYS, Abaqus, COMPRESS, PV Elite, Mathcad, or similar software. overseeing piping or vessel fabrication, supplier quality, weld qualification, nondestructive examination, and acceptance testing under nuclear quality assurance and design control processes.
- Competencies We are looking for a Sr.
- Mechanical Engineer who is: Technically rigorous: Comfortable working deeply in thermal analysis, stress analysis, equipment design, materials, codes, and failure modes.
About this role
You will serve as Oklo's technical expert for high-temperature process piping, pressure vessels, and pressure-retaining components supporting the Oak Ridge Fuel Recycling Facility (OFRF). You will own the mechanical design basis, analysis, code compliance, and technical interfaces for these systems from early design through fabrication, testing, installation, commissioning, and operational support.
Responsibilities
- Serve as Oklo's technical expert for high-temperature piping, pressure vessels, pressure boundaries, and their supporting components within the OFRF.
- Translate process temperatures, pressures, chemistry, flow conditions, vacuum and inert-gas requirements, operating cycles, and upset conditions into the piping and vessel design basis, applicable codes, load combinations, service life, and acceptance criteria.
- Perform and review piping stress and flexibility analyses for sustained, thermal, pressure, seismic, displacement, and other applicable loads, including equipment nozzle loads and support reactions.
- Perform and review pressure vessel analyses for internal and external pressure, local loads, nozzle loads, thermal gradients, buckling, fatigue, creep, and cyclic service, including design-by-analysis when appropriate.
- Perform and review steady-state and transient thermal analyses addressing heat loss, insulation, heat tracing, temperature gradients, heat-up, cooldown, and abnormal thermal conditions.
- Select and qualify materials for high-temperature and corrosive service, considering molten-salt compatibility, oxidation, thermal aging, creep, fatigue, radiation exposure where applicable, weldability, and fabrication constraints.
- Design and review vessels, piping, nozzles, flanges, closures, transitions, supports, anchors, restraints, expansion joints, bellows, penetrations, and other pressure-boundary components.
- Define piping layout, support, restraint, slope, drainability, isolation, inspection, and access requirements needed to manage thermal expansion and support safe operation and maintenance.
- Coordinate piping and vessel interfaces with process equipment, hot-cell penetrations, confinement boundaries, structures, utilities, and instrumentation; incorporate remote connection, inspection, isolation, removal, and replacement provisions where personnel access will be limited.
- Develop and review calculations, specifications, piping material classes, line lists, vessel data sheets, drawings, fabrication details, and technical requirements.
Preferred qualifications
- Master's degree or Ph.
- D. in Mechanical Engineering or a related technical discipline.
- Professional Engineer registration or the ability to obtain Tennessee licensure.
