US ITER Piping Analysis Engineer - Technical Staff Member

Date: Jan 20, 2022

Location: Oak Ridge, TN, US, 37830

Company: Oak Ridge National Laboratory

Requisition Id 7107 


We are seeking a US ITER Piping Analysis Engineer to provide full time analytical support resources for the US ITER project office through the duration of fabrication (Title 3) phase of the Central Solenoid Assembly Tooling, Final Design and fabrication of the Vacuum Systems (VAS and RPS), Electron Cyclotron Heating (ECH) system, and Ion Cyclotron Heating (ICH) system. Work includes performing, developing, and altering piping models and other calculations to evaluate and verify design concepts and to verify US designs to ITER International Office (IO) specified requirements and criteria. This position resides in the Analysis and Design Integration Group within US ITER project at Oak Ridge National Laboratory (ORNL).  


US ITER is a DOE Office of Science project hosted by Oak Ridge National Laboratory in Tennessee. Partner labs are Princeton Plasma Physics Laboratory and Savannah River National Laboratory. The US is a partner nation in ITER, an unprecedented international collaboration of scientists and engineers working to design, construct, and assemble a burning plasma experiment that can demonstrate the scientific and technological feasibility of fusion power for the commercial power grid. ITER's other partners are the People's Republic of China, the European Union, India, Japan, the Republic of Korea, and the Russian Federation. Involvement in ITER provides significant benefits for the US for a limited investment (less than 10% of construction costs): The US has access to all ITER technology and scientific data, the right to propose/conduct experiments, and the opportunity for US universities, laboratories and industries to design and construct parts.
