Mechanical Engineer 5 – NuScale Power

Location:

Remote within the contiguous United States; preference for work from the Corvallis, OR office. Travel to NuScale physical offices as needed.

Reporting to the Manager, NSSS Piping and Integration, this role performs design and analysis of the Nuclear Steam Supply System (NSSS) pipe systems in accordance with ASME BPVC Section III and applicable regulatory requirements. The engineer is part of the NSSS design engineering organization that generates technical requirements and associated design parameters for the modular advanced light water reactor (ALWR) NSSS.

All work is completed under ASME NQA‑1 quality assurance requirements and U.S. Nuclear Regulatory Commission guidelines.

• Possesses excellent knowledge in functional discipline and its practical application with detailed knowledge of applicable industry codes, standards and regulations.
• Performs complex piping design and stress analysis of ASME BPVC Section III Class 1, 2 and 3 piping systems using the Bentley AutoPIPE computer program in accordance with NB, NC, ND‑3600 requirements.
• Performs piping design and stress analysis of ASME BPVC Section III Class 1, 2 and 3 piping components using the ANSYS computer program in accordance with NB‑3200.
• Performs pipe support design and stress analysis of ASME BPVC Section III NF supports using hand calculations or ANSYS.
• Performs static and dynamic analysis, including response spectrum and time‑history analysis, to calculate stresses due to dead weight, thermal expansion, thermal gradients, seismic events and fluid transients.
• Prepares and reviews engineering specifications, drawings, CAD models and other documentation that communicate the design and technical aspects of piping components associated with NSSS systems. The development of drawings and CAD models is based on collaboration with drafters and requires the engineer to review models that have been developed in Siemens NX.
• Leads the evaluation of design solutions (piping re‑route, reconfigurations of supports, etc.) which satisfy piping stress criteria.
• Works on complex tasks in multiple and diverse areas.
• Interprets scope and project requirements.
• Acquires, maintains and develops training qualifications.
• Performs other duties as assigned.
• Provides oversight and mentoring to early‑career engineers in piping stress analysis and/or pipe support analysis.
• Certifies design specification for ASME BPVC Section III piping and/or piping supports.

• Problem solving – identifies and resolves problems in a timely manner, gathers and reviews information appropriately, uses own judgment, seeks input from others when needed.
• Oral/written communication – listens carefully, speaks clearly and professionally, edits work for accuracy and clarity, develops strong interpersonal networks.
• Planning/organizing – prioritizes and plans work activities, organizes personal and project timelines and deadlines, tracks project timelines efficiently.
• Adaptability – adapts to changes, manages competing demands, deals with frequent interruptions, changes, delays or unexpected events.
• Dependability – consistently on time, responds to management expectations, solicits feedback to improve performance.
• Team building – develops strong interpersonal networks, leads consensus by involving stakeholders, develops best solutions.
• Safety culture – adheres to NuScale safety culture, models safe behavior, influences peers to meet high standards.
• Quality assurance – commits to understanding and implementation of 10 CFR 50 Appendix B, 10 CFR 21 and ASME NQA‑1 regulations, standards and guidelines.

• Education/Certification:
  
  Minimum B.S. in Engineering (preferably Nuclear or Mechanical) from a four‑year ABET accredited institution. Advanced degree preferred. PE License in Mechanical or Nuclear Engineering required. Certifying Engineer experience to ASME BPVC Section III required.
• Experience:
  
  Minimum 15 years of highly relevant full‑time engineering experience.
  
  Experience with qualification of piping systems including ball joints desirable. Subject matter…
