Nuclear Pipe Stress Analysis Engineer

• Perform and review piping stress, flexibility, fatigue, and support-load analyses in accordance with ASME Section III, Division 1, including Subsections NB, NC, ND, and NF, and applicable ASME B31.1 Power Piping and ASME B31.3 Process Piping requirements. 
• Develop and evaluate load cases and combinations for pressure, deadweight, thermal expansion, seismic, vibration, water hammer, relief-valve thrust, and other static and dynamic loads in nuclear, fossil, and industrial applications. 
• Build, modify, troubleshoot, and independently check piping models using commercial and legacy analysis software, including AutoPIPE, CAESAR II, PIPESTRESS, ME101, ANSYS, or comparable tools. 
• Evaluate piping flexibility, equipment-nozzle loads, pipe supports and restraints, thermal transients, thermal stratification, vibration, and fatigue life. 
• Develop calculation packages, design reports, engineering justifications, and technical recommendations supporting new designs, plant modifications, operability, or continued operation. 
• Support failure evaluations, wall-thinning assessments, flaw evaluations, and fitness-for-service analyses for degraded piping and components. 
• Collaborate with multidisciplinary teams, including materials, metallurgy, chemistry, finite element analysis, vibration, fracture mechanics, and plant engineering, to develop integrated solutions. 
• Prepare technical documentation, present results in client meetings, support field activities as needed, and contribute to proposals and scope development for new work. 
• Contribute to internal tools, automation scripts, calculation templates, process improvements, and best-practice guidance for piping analysis and integrity evaluations. 

• B.S. in Mechanical or Civil Engineering; M.S. preferred. 
• 3 to 10 years of experience performing piping stress, flexibility, fatigue, or dynamic analysis in power generation, nuclear, process, or industrial facilities. 
• Working knowledge of ASME Section III, Division 1 piping design and analysis rules, particularly Class 1, 2, and 3 requirements under Subsections NB, NC, and ND, or demonstrated experience with ASME B31.1 and/or ASME B31.3. 
• Proficiency with one or more commercial piping analysis programs, such as AutoPIPE, CAESAR II, PIPESTRESS, or ANSYS, and the ability to interpret, verify, and clearly communicate complex analysis results. 
• Understanding of piping layout and flexibility, support and restraint behavior, equipment interface loads, thermal transients, vibration, and dynamic response. 
• Strong engineering judgment, problem-solving ability, communication skills, and technical writing capability. 
• Ability to work independently, review the work of others, and collaborate effectively within cross-disciplinary project teams. 
• U.S. citizenship or permanent residency required for certain nuclear projects. 

• Experience supporting nuclear plant design, operating plant modifications, license renewal or subsequent license renewal, power uprates, or advanced reactor programs. 
• Experience analyzing high-temperature piping systems, including service temperatures above 800 degrees F. 
• Experience with legacy piping models, software, and plant design bases, including the ability to interpret or convert models developed in programs such as ME101 or earlier versions of PIPESTRESS. 
• Familiarity with fracture mechanics, fatigue monitoring, environmentally assisted fatigue, thermal stratification, or fatigue evaluation methods. 
• Exposure to vibration field testing, flow-induced vibration diagnostics, operating deflection shape analysis, or troubleshooting of dynamic piping response. 
• Understanding of fitness-for-service methodologies, including API 579-1/ASME FFS-1, and familiarity with nuclear QA programs and industry guidance such as 10 CFR 50 Appendix B, EPRI, ASME, and WRC publications. 
• Experience with, or demonstrated interest and ability in, performing detailed finite element analysis and local stress evaluations of piping and piping components.
• Licensed Professional Engineer (P.E.) in one or more U.S. states
