Join us at the forefront of nuclear engineering innovation

We are pleased to announce that Cervenka Consulting will participate in the upcoming SMiRT 28 conference (Structural Mechanics in Reactor Technology), taking place in Toronto, Canada, August 10-15th, 2025.

Our cutting-edge nonlinear finite element analysis software ATENA will be showcased both through technical presentations and at our exhibition booth #20.

Visit our exhibition stand
Come meet our team in the exhibition area (booth no. 20) to see live demonstrations of the new ATENA 2025 simulation system and learn how it supports advanced analysis and the structural assessment of nuclear facilities. We will be available throughout the conference to discuss your challenges and share practical examples from recent projects.

Technical Presentations by CEO Jan Červenka
Both talks are part of TS44-D3: Computational Simulation and Visualization and will take place on Thursday, August 14, in Pier 3:

- P. Bocan, Modelling Uncertainty in Nonlinear Analysis for Digital Twins in the Assessment of NPP

10:45 - 11:00, Thursday Aug. 14, Room Pier 3 

(Paper ID 580) Explore how ATENA contributes to digital twin development through robust nonlinear modeling and uncertainty quantification for nuclear power plants.

- J. Cervenka, Neutron Radiation Effect on Concrete Mesoscale Samples and Concrete Structures 

11:00 - 11:15, Thursday Aug. 14, Room Pier 3

(Paper ID 584) This presentation investigates the impact of neutron radiation on concrete at the meso- and macro-scale level and its implications for structural safety, analyzed using ATENA.

We look forward to connecting with researchers, engineers, and industry professionals during the conference. Whether at our booth or in the technical sessions, we invite you to discover how ATENA can support your work in nuclear structural engineering. And don’t forget — the latest version of ATENA is now available as a free trial with full capabilities. Download it here: https://www.cervenka.cz/products/atena/trial
