ESI SYSTUS allows nuclear engineers to pre-qualify new component designs in accordance with nuclear industry regulations. SYSTUS offers a complete resolution to analysis challenges in mechanics, heat transfer, and electrotechnics, and aims to help you verify the behavior of energy components – such as nozzles, primary circuit pumps, the reactor, and the steam generator, also in addition to other industrial componentssuch as valves – during the design phase and accelerate decision-making during maintenance operations.

Highlights of SYSTUS 2022

FRACTURE MECHANICS

• Additional results for Gthêta computation (Temperature T, Young’s Modulus E and Equivalent Stress Intensity Factor Keq).
• Crack Insertion application in Visual-Mesh, to mesh crack in a 3D model.
• Improvement of the fracture mechanics post-processor manager in Visual-Environment. It enables users to compute easily Stress Intensity Factor and Energy release rate and now to display results of G along crack front and along time.

REGULATORY ANALYSES

• NEWREG is the SYSTUS new module for regulatory analyses in accordance with ASME and RCC-M codes. For this release new options are available, and scalability has been improved.
• Development of new options and functionalities:

o    Ke user
o    Labels Combination, NOTH, new tables, etc

PYTHON LANGUAGE

• the PYTHON language has been integrated into SYSTUS since its 2016 version.
