Aircraft Impact Analysis (AIA)
The U.S. Nuclear Regulatory Commission (NRC) mandates that all new nuclear power reactor designs undergo a rigorous, design-specific assessment of potential large commercial aircraft crash impacts. This requirement, detailed in
10 CFR 50.150, ensures reactors incorporate robust features to maintain:
- Core cooling,
- Containment integrity,
- Spent fuel cooling
—all with minimal operator intervention during such an event.
At Trio Structures, we specialize in performing AIA for next-generation Small Modular Reactor (SMR) buildings, leveraging advanced explicit Finite Element Modeling (FEM) software. Our simulations validate structural resilience against aircraft collisions, ensuring compliance with NRC standards while optimizing safety and operational continuity.
Vehicle Barrier Impact Analysis
Highway barriers must now comply with the updated AASHTO Manual for Assessing Safety Hardware (MASH) requirements to ensure enhanced safety and performance. These standards mandate rigorous crash testing for both permanent and temporary safety features, including barriers, to better protect motorists.
Trio Structures has in-house capabilities to model AASHTO MASH Test Levels, enabling us to qualify new barrier designs without physical testing. Our advanced simulations ensure compliance with safety standards while saving time and resources.
Fluid Structure Interaction Modeling
Modeling Fluid-Structure Interaction (FSI) is crucial in nuclear applications due to its ability to simulate the complex interactions between coolant fluids and reactor structures. Accurate FSI models help ensure the structural integrity and safety of nuclear reactors under various operating conditions, including thermal and pressure loads.
This capability is vital for predicting and mitigating potential failure modes, optimizing reactor design, and enhancing the overall efficiency and reliability of nuclear power plants. By providing detailed insights into the dynamic behavior of reactor components, FSI modeling supports the development of safer and more resilient nuclear energy systems.
Advance Connection Design
Advanced connection design and the prediction of elastic and inelastic buckling are critical components in structural engineering. These processes involve the use of sophisticated modeling techniques and materials science to ensure that connections within a structure can withstand various loads and stresses.
By accurately predicting how materials will behave under both elastic (reversible) and inelastic (permanent) deformation, engineers can design connections that maintain structural integrity during extreme events, such as earthquakes or heavy winds. At Trio Structures, we have supported the development of innovative connections that facilitate ease of construction by introducing unique solutions backed by advanced modeling technologies.
Design of Structures For Fire and Elevated Temperatures
Analyzing structures for fire and elevated temperature loads involves assessing how materials and structural elements respond to high heat and potential fire exposure. This process includes evaluating the thermal properties of materials and how material strength degrades as temperatures increase.
Advanced simulations and fire testing are employed to model the effects of fire on structural components, helping to identify potential weaknesses and improve fire safety designs. This analysis is crucial for developing buildings and infrastructure that can withstand extreme fire conditions, ultimately protecting lives and property.
At Trio Structures, we possess state-of-the-art capabilities to simulate system responses at elevated temperatures. Our approach is validated by a comprehensive suite of experimental fire testing data, ensuring accurate and reliable results for fire-resistant designs.
