Position Title: Principal Engineer Seismic/CSA Integration & Oversight
Position Description: Protingent Staffing has an exciting contract Principal Engineer Seismic/CSA Integration & Oversight opportunity.
Job Responsibilities: - Provide continuous oversight of seismic design scope, covering building and structural systems, foundations, equipment supports, and integrated plant analyses such as soil–structure interaction (SSI), seismic fragility development, and PRA inputs.
- Coordinate and direct complex multi-system analyses, including SSI studies, seismic model development, external hazard characterization, and building seismic qualification, ensuring consistency with plant-level methodologies and licensing strategy.
- Perform and guide SSI analyses using in-house SASSI tools; establish repeatable frameworks, workflows, and benchmarks that improve analysis efficiency and traceability across multiple structures.
- Develop, document, and implement seismic design bases and strategies, supporting both deterministic and probabilistic methods; apply risk-informed, performance-based methodologies (e.g., LMP, RIPB) to define design acceptance criteria for SSCs.
- Author, review, and refine plant- and system-level requirements and specifications, integrating seismic and structural criteria into design deliverables and ensuring seamless alignment with plant-level engineering.
- Interface across design disciplines (mechanical, I&C, nuclear safety, systems) to ensure seismic requirements, structural criteria, and performance expectations are clearly defined, properly allocated, and implemented across interfacing designs.
- Ensure adherence to licensing and code requirements (ASCE, ACI, AISC, ASCE 4/7/43, NUREG guidance), verifying they are correctly integrated into CSA products and aligned with Company's licensing strategy.
- Support cost studies and trade-off evaluations as the CSA/seismic SME, ensuring technical rigor while balancing constructability, schedule, and economic considerations.
- Surveil subcontractor performance, monitoring design deliverables, verifying compliance with technical requirements, and ensuring design processes and quality programs are properly implemented.
- Lead and support design and integration reviews, chairing cross-functional resolution sessions for CSA/seismic challenges, and facilitating targeted technical forums (e.g., working groups, decision boards, digital/in-person reviews).
- Integrate seismic and CSA design information into licensing products, including regulatory submittals under the Licensing Modernization Project (LMP), ensuring design-basis alignment with licensing commitments.
- Report emerging technical risks to project and engineering management, providing timely recommendations for mitigation and escalation when needed.
- Drive continuous improvement, applying nuclear industry best practices to seismic modeling, fragility methods, and structural qualification, while identifying opportunities for improved efficiency, quality, and integration.
