Nuclear Fatigue Engineering Sr Consultant
Structural Integrity Associates, San Jose, California, United States, 95199
Base Pay Range
$129,960.00/yr - $237,000.00/yr
Job Description Structural Integrity Associates, Inc. (SIA) is seeking a Senior Consultant / Associate with deep expertise in ASME Section III fatigue analysis (NB-3200), environmental fatigue, and finite element analysis (FEA) to support our Nuclear Business Unit. The ideal candidate brings experience developing and reviewing fatigue evaluations for nuclear plant components, executing high‑fidelity ANSYS models, and contributing to and overseeing fatigue monitoring systems, including software‑enabled workflows and data analytics. The role includes technical execution, project leadership, client interfacing, and contributions to proposals and R&D/industry initiatives (e.g., license renewal, life extension).
The work environment is highly collaborative. SIA leverages expertise in Materials, Chemistry, Vibration, and Advanced Reactors to deliver solutions that enhance component reliability, extend service life, and improve safety.
Primary Responsibilities
ASME Code Fatigue & Environmental Fatigue
Lead and perform fatigue analyses per ASME Section III NB-3200 (simplified elastic‑plastic and non‑linear elastic‑plastic methods)
Execute and review environmental fatigue evaluations aligned with NUREG/CR‑5704/6583/6909 and related guidance
Develop transfer functions/system logic; interpret transients, usage factors, CUF/CUFen, and margin assessments
Finite Element Analysis (FEA)
Build and validate detailed ANSYS models (thermal, structural, vibration, non‑linear); perform model reduction and sensitivity studies
Perform stress classification, fatigue hotspot assessment, thermal‑mechanical transient analysis, and validation against test/plant data
Fatigue Monitoring Systems & Tooling
Support and evolve FatiguePro‑based workflows (inputs/methods/QA), including data pipelines and dashboards for monitoring
Author and review software requirements/use cases; partner with internal software teams on testing and verification of analytical routines
Technical Leadership & Delivery
Provide technical oversight and rigorous technical review
Prepare high‑quality technical reports, calculation packages, test plans, and client deliverables
Client Engagement & Business Development
Serve as a subject‑matter expert to troubleshoot plant issues and support license renewal and subsequent license renewal programs
Contribute to proposals, scopes, estimates; identify growth opportunities in fatigue monitoring and code‑based analysis services
Collaboration & R&D
Collaborate across disciplines; contribute to internal R&D roadmap and industry activities (e.g., EPRI participation, method improvements)
Required Skills / Qualifications
MS in Civil/Structural/Mechanical Engineering (or related). Relevant nuclear/industry experience may substitute for advanced degree
5+ years (Consultant) to 10+ years (Senior Consultant) of relevant experience in nuclear fatigue and FEA for safety‑related components
Demonstrated expertise with ASME Section III NB-3200 fatigue methods (simplified elastic‑plastic and non‑linear elastic‑plastic)
Working knowledge of environmental fatigue methods consistent with NUREG/CR‑6909
Strong proficiency with ANSYS for thermal/structural/vibration/non‑linear analyses
Proven ability to author calculations, interpret results, and present clear technical recommendations to clients
Excellent communication and technical writing; ability to lead reviews and mentor junior engineers
Ability to travel (~5‑10%) for client meetings, plant/site support, and testing
Eligibility to obtain Nuclear Unescorted Access Authorization (UAA) as required
Desired Skills / Qualifications
10+ years in the nuclear industry, preferably including license renewal (LR/SLR) and operating fleet experience
Experience with fatigue monitoring systems (e.g., FatiguePro): configuration, logic development, verification/validation, and data QA
Familiarity with software development workflows (requirements, test plans); C/C++/C# exposure is a plus for analytical toolchains
Experience leading multi‑disciplinary teams performing high‑level technical oversight and client engagement
Knowledge of nuclear plant systems, thermal‑hydraulic transients, and integration of plant data into fatigue and FEA models
Pay Range The expected salary range for this role is $153,900 – $237,000 in San Jose, CA; $129,960 – $201,960 in Denver, CO; and $121,500 – $191,280 in Charlotte, NC. Exact pay will be commensurate with experience.
