Principal Engineer, SeismicCSA Integration & Oversight

TITLE: Principal Engineer Seismic/CSA Integration & Oversight

LOCATION: Reston VA USA

TerraPower is a nuclear energy technology company based in Bellevue Washington. At our core we are working to raise living standards globally. The essential factor 2006 the company originated with Bill Gates and a group of like-minded visionaries who evaluated the fundamental challenges to raising living standards around the world. They recognized energy access was crucial to the health and economic well-being of communities and decided that the private sector needed to take action and create energy sources that would advance global energy is to be a world leader in new nuclear technologies while developing innovators and future leaders in the nuclear committed to bringing sustainable affordable and safe energy to address global a result the companysactivities in the fields of nuclear energy and related sciences are yielding significant innovations in the safety and economics of nuclear power hybrid energy and medical applications.

Principal Engineer Seismic Integration & Oversight

TerraPower LLC. Is seeking a highly motivated Principal Engineer to support Seismic and CSA Integration for TerraPowers advanced nuclear reactor this role you will support the development of plant level requirements and strategies relevant to complex seismic design and licensing activities perform technical review of work products and facilitate the integration and implementation of strategies and work products across project disciplines. Candidates must have extensive experience in seismic design and analysis soil-structure interaction (SSI) analysis civil/structural design and analysis safety and probabilistic analysis seismic fragility evaluations peer review with a focus on seismic vulnerabilities (seismic interactions) and requirements/criteria development for nuclear power projects.

The Seismic/CSA Integration Engineer will provide regular in-person oversight and support for the Natrium project design work carried out by Bechtel at their Reston VA headquarters. The successful candidate will coordinate with engineers working on structures systems components and engineering analyses for successful integration of input and requirements for nuclear plant seismic design and analysis.

The ideal candidate will be located in Bechtels Reston VA office to allow continuous in-person support collaboration and oversight between Bechtels CSA and GSH&E organizations and TerraPowers EPC Oversight team. Candidate would travel periodically to TerraPowers Bellevue office to meet with Natrium managers and stakeholders. The Engineer will coordinate scope schedule and technical integration for system design 3D model and drawing development and also support cross functional collaboration with licensing safety analysis and PRA.

Responsibilities

• Provide continuous oversight of Bechtels CSA and seismic design scope covering building and structural systems foundations equipment supports and integrated plant analyses such as soilstructure 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 Bechtels 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 Bechtels CSA products and aligned with TerraPowers 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 Bechtel and 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.

Key Qualifications & Skills

• Education: M.S. degree in Civil engineering or equivalent or higher
• 12 years of civil/structural design and analysis and/or probabilistic risk assessment experience
• Excellent writing and communication skills
• Ability to work independently and with minimum direction to solve challenging problems
• Candidate must have strong analytical/problem solving skills
• Candidate must be a self-starter and possess ability to coordinate with internal and external engineering and design teams with minimal direction
• Experience with new nuclear power plant design projects
• Experience with risk-Informed performance based and probabilistic methodologies for application to seismic design and analyses
• Experience in a broad range of design and integration topics throughout a product lifecycle including conceptual design final design and construction
• Experience with structural design for complex external hazard loading such as seismic and aircraft impact
• Experience with commercial codes and standards such as UBC ACI 318 AISC 360 and ASCE 7
• Experience with nuclear codes and standards such as ACI 349 ACI 359 AISC N690 ASCE 4 and ASCE 43
• Experience working projects with NRC or DOE regulations
• Ability to deliver projects that include many competing objectives and design constraints with ability to resolve conflicts between objectives.
