REMOTE Structural/Mechanical Analysis Engineer

EGS is hiring a Structural/Mechanical Analysis Engineer to support structural and mechanical evaluations of elevated-temperature nuclear components under ASME BPVC Section III, Division 5. The role performs code-compliance analyses and prepares independently reviewable calculation packages supporting component integrity and safety.

Responsibilities:

• Support structural/mechanical analysis in accordance with ASME BPVC Section III, Division 5 code requirements
• Perform load-controlled stress evaluations, stress classification, and stress linearization for elevated-temperature nuclear components
• Develop finite element analysis (FEA) models, including 3D model development, mesh convergence studies, and boundary condition documentation, using tools such as ANSYS, Abaqus, or equivalent
• Produce code-compliant, independently reviewable calculation packages and supporting reports
• Perform creep-fatigue damage evaluation, including time-dependent creep and fatigue interaction, usage factors, and hold-time effects, per Subsection HBB / Mandatory Appendix HBB-I
• Conduct strain limits, ratcheting, and incremental collapse assessments
• Evaluate elevated-temperature buckling, including thermal and creep buckling
• Collaborate with technical leads and senior engineers to review analysis results and ensure technical accuracy
• Support evaluation of weld strength reduction factors, dissimilar metal weld assessments, or bolted joint fatigue/relaxation analysis under Division 5, as needed
• Apply working knowledge of Section III, Division 5 or demonstrate transferable experience from Section III Division 1 or Section VIII with elevated-temperature exposure
• Reference Section II, Part D material allowables as applicable to analysis tasks
• Participate in periodic technical coordination calls to align on scope, progress, and findings
• Other duties as assigned by the technical lead or engineering manager

Requirements:

• MUST BE US CITIZEN
• Working knowledge of ASME BPVC Section III, Division 5 nuclear component design requirements
• FEA experience, including 3D model development, mesh convergence, and boundary condition documentation
• Ability to apply general code rules to specific analysis problems to produce technically sound, defensible results
• Ability to combine analytical results to form conclusions supporting code-compliance determinations
• Ability to listen to and understand technical information and ideas presented through discussion with technical leads and stakeholders
• Ability to communicate analysis results and technical findings clearly, in writing and verbally
• Candidates must possess a Bachelor of Science degree in mechanical engineering or a directly related field, with a minimum of 8 years of relevant experience; or a Master of Science degree in mechanical engineering or a directly related field, with a minimum of 6 years of relevant experience. The qualifying degree must be from an ABET-accredited program
• 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
• Familiarity with Section II, Part D material allowables
• Prior DOE national laboratory or nuclear component supplier experience
