Seeking an experienced Structural/Mechanical Analysis Engineer to provide support to our client in Idaho Falls, ID. The role involves performing structural and mechanical analysis support for elevated-temperature nuclear component design evaluations in accordance with ASME BPVC Section III, Division 5.

What You Will Do

Performing load-controlled stress evaluations, stress classification, and linearization for elevated-temperature nuclear components, developing finite element analysis (FEA) models, and producing code-compliant, independently reviewable calculation packages.

Why It Might Be a Fit

The ideal candidate will have a strong working knowledge of ASME BPVC Section III, Division 5, experience with FEA tools, and the ability to produce code-compliant calculation packages.

Requirements

• Bachelor of Science degree in mechanical engineering or a directly related field, with a minimum of 8 years of relevant experience; or Master of Science degree in mechanical engineering or a directly related field, with a minimum of 6 years of relevant experience.
• Working knowledge of ASME BPVC Section III, Division 5 (or demonstrated transferable experience in Section III Division 1 or Section VIII with elevated-temperature exposure).
• FEA experience (ANSYS, Abaqus, or equivalent), including 3D model development, mesh convergence, and boundary condition documentation.
• Hands-on experience with creep-fatigue damage evaluation, including time-dependent creep and fatigue interaction, usage factors, and hold-time effects, per Subsection HBB / Mandatory Appendix HBB-I.
• Experience with strain limits, ratcheting, and incremental collapse assessment.
• Experience with elevated-temperature buckling, including thermal and creep buckling.
• Demonstrated ability to produce code-compliant, independently reviewable calculation packages.
• Experience with weld strength reduction factors, dissimilar metal weld assessment, or bolted joint fatigue/relaxation analysis under Division 5.
