PROGRESSING IN THE DEVELOPMENT OF INDUSTRIAL CODES AND METHODS DEDICATED TO VVERS
IMPROVING PHYSICAL PHENOMENA TREATMENT VIA BEST ESTIMATE CALCULATIONS AND UNCERTAINTIES QUANTIFICATION
DEFINING THE FIRST GUIDANCE SUITABLE FOR WESTERN PWRS AS WELL AS VVERS
IMPROVING PHENOMENA COMPREHENSION VIA EXTENSIVE USE OF 3D-MODELLING AND MULTIPHYSICS CALCULATIONS
Current codes and methods used for VVER safety assessment are subjected to growing international export controls from outside EU, threatening the EU sovereignty and security in terms of energy supply. A new generation of innovative codes and methods are under development within Europe. They are improving 3D-multiphysics modelling and uncertainty quantification capabilities and are worth being transferred from lab to industry as they will substantially improve the physics comprehension of PWR and VVER. European codes and methods development for VVER safety assessment will open the VVER market to the European nuclear industry. CAMIVVER will perform developments required for the new generation codes and will generalize 3D-multiphysics coupling, performing benchmark against current industrial codes used for PWR and VVER safety assessment. CAMIVVER will demonstrate CFD assets and compatibility with uncertainty propagation in the frame of a safety assessment.
