Experimental Investigation of a Helium-Cooled Breeding Blanket First Wall under LOFA Conditions and Pre-Test and Post-Test Numerical Analysis

The experimental investigation of a prototypical set-up simulating loss flow accident in helium-cooled breeding blanket first wall mock-up under typical heat load conditions is presented. campaign reproduces the expected DEMO thermal-hydraulics during normal and off-normal situations aims at providing some insight into fast transients associated with wall. definition matrix are discussed, including pre-test analysis performed support these activities. major results procedure using acquired data for validating calibrating RELAP-3D model introduced. All activities contributed to creation relevant theoretical practical experience that can be used further studies concerning incidental real-plant scenarios framework plant fusion safety
