LFR safety features through intrinsic negative reactivity feedbacks

  • 1. ENEA, UTFISSM - Technical Unit for Reactor Safety and Fuel Cycle Methods (Italy)

Description

The safety of Lead-cooled Fast Reactors can rely on intrinsic features such as: • the impossibility of Lead boiling, hence the unreliability of core (only) voiding; • the buoyancy of Control Rods in Lead, allowing their safe positioning also below the active region. For heightening the safety features of LFRs in safety analyses it could be required to approach the evaluation of the reactivity coefficients from a more physical point of view, including more elementary mechanisms, each one related to the proper driving temperature
