Among the events that can lead to core damage in Sodium-cooled Fast Reactors (SFRs), the Unprotected Loss of Flow (ULOF) is considered a critical postulated event due to the limited time margin before core damage occurs. This study explores the potential for a core design that demonstrates high robustness in terms of safety and security, specifically addressing the positive void reactivity inherent in the design.
