Civil & Structural Engineering

Our civil and structural engineering team performs analyses and design services for nuclear power plant structures, including support of plant systems and components. Seismic analyses of plant structures, systems, and components (SSCs) are conducted to meet each station’s licensing and design basis requirements.

These engineers are engaged in most plant design modification projects. Analyses and design include the qualification of piping and piping support systems to the requirements of the ASME Boiler & Pressure Vessel Code, B31 Power Piping Code, AISC and other codes and standards following each station’s licensing and design basis. Piping and pipe support qualifications are performed utilizing software approved by each station’s license documents.

We evaluate and analyze simple structures (such as component supports) and more complex structures (such as nuclear plant auxiliary buildings) utilizing GT STRUDL^® and other software tools. We support station personnel with implementation activities with heavy load path and rigging evaluations. In cooperation with Fire Protection engineering, fire and flood seals are evaluated and designed.

In addition to GT STRUDL® software, we are experienced in the use of other proprietary software utilized to analyze and modify SSCs at the individual stations, including STAADTM, ME101TM, ME035TM, ME150TM, STARDYNETM, MFRAMES, STRUDLTM, MathCAD®, MatLAB®, FAPPSTM, and MAPPSTM.

Areas of service and expertise include:

• Design and analysis of plant structures
• Seismic analysis of systems, structures and components
• Heavy load path evaluations
• Structural design basis and licensing basis reconstitution and reviews
• Rigging evaluations
• Pipe support and pipe stress design and analysis
• Design/analysis of suspended systems
