Evaluation of Computational Fluid Dynamics Methods for Reactor Safety Analysis

Project ID: FIKS-CT-2001-00154
Funded under: FP5-EAECTP C

Abstract

The objective of the ECORA project is to evaluate the capabilities of Computational Fluid Dynamics (CFD) software packages for simulating flows in the primary system and containment of nuclear reactors. The interest in the application of CFD methods arises from the importance of three-dimensional flow effects in these reactor components, which one-dimensional system codes cannot predict. Therefore, the ECORA project will identify application areas for detailed three-dimensional CFD calculations and make recommendations for software improvements.
The software assessment includes the establishment of Best Practice Guidelines (BPG) and standards regarding the use of CFD software and the evaluation of CFD results for safety analysis. Quality criteria for the application of CFD software are standardised. CFD results are only accepted after these quality criteria are satisfied. Thus, a general basis for assessing merits and weaknesses of particular models and codes is formed on a European basis. CFD simulations having an accepted quality level will increase confidence in the application of CFD-tools.
