Mechanical Engineer 3 (NSSS Piping & Integration)

NuScale Power develops modular advanced light water reactor nuclear technology and related Nuclear Steam Supply System (NSSS) components. The Mechanical Engineer 3 performs piping design and stress analysis, pipe support analysis, static and dynamic analysis, and prepares or reviews engineering specifications, drawings, CAD models, and related documentation in accordance with ASME and nuclear regulatory requirements.

Responsibilities:

• Performs 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 the requirements of NB, NC, ND-3600, respectively
• 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 the requirements of NB-3200 (preferred)
• Performs pipe support design and stress analysis of ASME BPVC Section III NF supports using hand calculations or ANSYS computer program
• Performs static and dynamic analysis including response spectrum and time history analysis to calculate stresses due to deadweight, thermal expansion, thermal gradients, seismic events, and fluid transients
• Prepare and review 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 reviews models that have been developed in Siemens NX
• Offers design solutions (piping re-route, reconfiguration of supports, etc.) in order to satisfy piping stress criteria with assistance from subject matter experts
• 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

Requirements:

• A minimum of a B.S. degree in Engineering, preferably Nuclear or Mechanical Engineering, from a four year ABET accredited college or university
• Minimum of 6 years of full-time, relevant professional experience
• Experience with design and stress analysis of ASME BPVC Section III piping systems in accordance with the requirements of NB, NC, or ND-3600
• Eligible to work under Department of Energy 10 CFR Part 810
• A professional engineer (P.E.) certification is preferred
• Experience with the Bentley AutoPIPE computer code is desirable (similar code is acceptable)
• Experience with design and stress analysis of ASME BPVC Section III piping components using ANSYS computer program in accordance with the requirements of NB-3200 (preferred)
• Experience with ASME Section III NF (preferred)
