Progress towards the validation of SIMMER-III code model for lead-lithium water chemical interaction

•SIMMER-III code validation for WCLL in-box LOCA assessment•Lead-lithium eutectic and water chemical interaction•Numerical Analysis of Experimental Test E5.2•Execution of the Series E experimental campaign employing the facility, LIFUS5/Mod3Research activities are continuing between the University of Pisa and ENEA Brasimone Research Center to better understand the phenomena and processes that occur during a postulated in-box LOCA in the Water-Cooled lead-lithium Breeding Blanket (WCLL BB) and during the system's safety response. Various activities are also going on to strengthen the reliability of numerical tools and validate computer models, codes, and procedures for their implementations.
