Framework
• A detailed and highly flexible numerical tool to study criticality accidents has been developed
• The tool implements a Multi-Physics coupling using neutronics, thermal-hydraulics and thermal-mechanics models based on Open FOAM and SERPENT codes
• Two neutronics models: Quasi-Static Monte Carlo and SPN
Objective:
In this work a system composed by a 2D square liquid fuel cavity filled with a fuel molten salt has been used to:
• Investigate the performance of the tool’s thermal-hydraulics and neutronics solvers coupling numerical scheme
• Evaluate possible strategies for the implementation of the Quasi-Static (QS) method with the Monte Carlo (MC) neutronics code
• Compare the QS-MC approach precision and computational cost against the Simplified P3 (SP3) method
