Mechanical Engineering Analyst - Technical Staff Member

Date: Dec 28, 2021

Location: Oak Ridge, TN, US, 37830-8050

Company: Oak Ridge National Laboratory

Requisition Id 6956 


We are seeking a Mechanical Engineering Analyst who provide full time structural analytical support resources for the US ITER project office through the duration of fabrication (Title 3) phase of the Central Solenoid, Final Design of the Ion Cyclotron Heating (ICH) system and Final Design of the Vacuum Systems (VAS). 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. 



Major Duties/Responsibilities: 

  • Performing and developing and altering existing FEA models, FEA analysis, and other calculations to evaluate and verify design concepts related to non-conformances,
  • Checking analytical work of other project participants
  • Participating as a subject matter expert in design reviews in systems
  • Performing trade off studies of competing designs
  • Verifying US ITER designs to ITER International Office (IO) specified requirements and criteria
  • Advising on application of ASME and international mechanical design codes and standards and providing the detailed structural assessment of design features,
  • Support structure hardware, piping systems and handling fixtures.  
  • Perform various analyses, including linear/nonlinear structural analysis of various Tokamak components, and formally document all analysis results;
  • Prepare technical reports and present findings at technical reviews
  • Both domestic and foreign travel (<25%)


Basic Qualifications:

  • Master’s Degree in Mechanical Engineering and at least 4 years of related work experience
  • Advanced finite element modeling using ANSYS including Classical and/or Workbench interfaces for multi-physics applications
  • Experience in analysis of energy systems including cryogenics, vacuum systems, and/or large electro-mechanical devices


Preferred Qualifications:

  • PhD Degree in Mechanical Engineering
  • 15 or more years of specialized experience in design, fabrication and assembly of large-scale fusion energy, research related, or nuclear hardware 
  • Experience with the ASME Boiler and Pressure Vessel Code
  • Demonstrated ability to independently evaluate problems, investigate and propose solutions, perform calculations, apply industry codes and standards, and document design and fabrication activities
  • Demonstrated knowledge in utilizing and managing CAD software for preparation of analysis de-featuring.  CATIA experience desirable.
  • Familiarity or experience with superconducting electromagnets and fusion energy (nuclear) technology.
  • Experience with piping design (ASME B31.3 and/or EN equivalent).
  • Experience in reviewing detailed mechanical drawings in accordance with ASME Y14.5.
  • Cryogenic experience
  • Electromagnetic analysis experience with FEA tools such as ANSYS Maxwell, Vector field/Opera, or similar type of electromagnetic analysis software
  • Demonstrated ability to prepare technical specifications, statements of work, procedure and test plans.
  • Solid understanding of mechanical design and analysis fundamentals and their application to mechanical hardware
  • Ability to evaluate non-conformances and deviations from drawings, technical specifications, and requirements.
  • Ability to maintain effective working relationships with a diverse international project team.
