Job description

NOTE: FOR THOSE LIVING WITHIN A 30-MILE RADIUS OF A CURRENT NUSCALE OFFICE LOCATION, AN ONSITE PRESENCE OF 4 DAYS PER WEEK WILL BE REQUIRED. OTHERWISE, IF GREATER THAN A 30-MILE RADIUS, BUT WITHIN THE CONTIGUOUS UNITES STATES, THIS POSITION MAY BE AVAILABLE FOR REMOTE WORK WITH TRAVEL AS REQUIRED FOR BUSINESS NEEDS.

POSITION SUMMARY: Reporting to the Manager, NSSS Piping and Integration, this position performs design and analysis of the Nuclear Steam Supply System (NSSS) pipe systems in accordance with ASME BPVC Section III and applicable regulatory requirements. This position 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. Utilizing proven state-of-the-art methodologies NSSS components are engineered to nuclear industry standards. All work within the NSSS design organization is completed under ASME NQA-1 quality assurance requirements and respective U.S. Nuclear Regulatory Commission guidelines.

ESSENTIAL DUTIES AND RESPONSIBILITIES

• 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 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.
• Provides oversight and mentoring to early career engineers in the area of piping stress analysis and/or pipe support analysis.
• 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.
• 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.
