Atomenergoproject implemented Abaqus Unified FEA from SIMULIA to replace outdated analysis methods for evaluating dynamic forces such as earthquakes and plane crashes on nuclear structures. The software enabled comprehensive modeling of structure-foundation interaction, material nonlinearities, and contact behavior for concrete, soil, and metals. Training and phased rollout allowed engineers to apply realistic simulation across multiple design projects, improving accuracy and supporting regulatory safety requirements.

Key takeaways

Abaqus supports linear and nonlinear dynamic analysis of nuclear structures including foundation interaction.

Realistic simulation replaced legacy methods for evaluating earthquake, impact, and contact loads.

Material models cover concrete, soil, metals, and elastomers with geometric and contact nonlinearities.

Phased implementation with vendor training enabled rapid adoption and custom feature requests.

Improved design accuracy and plant safety validated through use on VVER-1200 and other reactor projects.
