Liquid metals such as Bi and Pb and Pb≠Bi eutectic alloy are serious contenders for use as coolant in LMFBRs in
lieu of sodium due to a number of attractive characteristics (high density, low moderation, low neutron absorption and
activation, high boiling point and poor interaction with water and air, etc.). Analysis of hypothetical accidents is of
relevance to predict the catastrophe involving loss of coolant accident (LOCA) in LMFBRs. One key parameter to take
into account is the critical temperature data of the liquid metals for reactor safety analysis. This communication reports
the application of a theoretical model called internal pressure approach to predict the critical temperature (Tc) of the
LBE alloy for the first time.

1. Introduction
Analysis of hypothetical yet highly improbable and
undesirable accidents in the water-cooled thermal
nuclear reactors as well as the liquid metal-cooled fast
breeder nuclear reactors (LMFBRs) is of paramount
importance. Such analysis is relevant to predict the
catastrophe and ensure the desired safety throughout
