Status, Features, and Future Development of the LIFUS5/Mod4 Experimental Facility Design

The Water-Cooled Lithium–Lead (WCLL) is one of the most promising technologies for power conversion and tritium production in future fusion-powered reactors; it will be implemented Test Breeding Modules (TBM) inside ITER reactor DEMO EU reactor. However, simultaneous presence system high-temperature PbLi high-pressure water poses significant safety issues event an in-box LOCA (Loss Of Coolant Accident). For this reason, a complete understanding response crucial to avoid extensive damage such scenario. This paper describes status design features LIFUS5/Mod4 facility, experimental plant that currently being designed constructed at ENEA CR Brasimone framework FP9 EUROfusion Horizon Europe address these issues. facility aims representative geometry operational conditions System (TBS) allow precise reproduction its behavior under simulated incidental scenarios. peculiar choices have been made, which extensively discussed throughout work generation high-quality data useful TBS development. Moreover, expected become test stand implementation different functions, identify best accident-mitigation strategy. Possible upgrade plans are described as well, with chance fully functional any component their operative conditions.
