Numerical Investigation of LIFUS5/Mod3 Series E Experiment Test 5.1 Towards Thermal-Hydraulic System Code "SIMMER-III" Validation

EasyChair Preprint 9711

Abstract

Under this study, the LIFUS5/Mod3 Series E experiment Test 5.1 is being numerically investigated and compared with the experimental parameters to validate the thermal-hydraulic safety analysis system code "SIMMER III" for the interaction of lead-lithium and water under circumstances similar to those anticipated for the Water-Cooled Lead Lithium Breeding Blanket (WCLL-BB) under accident situations so that the code can accurately predict these transients and accidents. Experimental studies continue to be conducted to investigate the dynamics and reactions that occur during a hypothesized in-box LOCA in the WCLL-BB and throughout the system's protective response by the University of Pisa and ENEA Brasimone Research Center. Additionally, several initiatives are being undertaken to enhance the predictability of computational tools and validate the safety analysis system codes, modeling techniques, and successful implementation. In particular, the experimental Test E5.1, conducted in the distinct effect test facility LIFUS5/Mod3, has been numerically reproduced for the present study (installed at ENEA Brasimone Research Center). The University of Pisa updated a version of the SIMMER-III numerical algorithm utilized for the mathematical model to accommodate the chemical interaction between the two fluids.
