Abstract
Heavy liquid metals (HLM), such as mercury (Hg), lead (Pb), bismuth (Bi) and lead-bismuth eutectic (Pb-Bi), have being studied in several countries as potential materials for intensive spallation neutron sources, due to a high neutron yield per incident proton and heat removal capacity. However, experimental data on their thermal properties in the temperature range of interest are rare. It makes difficult the design calculations and the prognosis of the normal and abnormal behaviour of the spallation targets. In this case, physically based correlations and an equation of state (EOS), developed on the basis of the fundamental thermodynamics and limited experimental data, can play a very important role. Recently a compilation with the recommendations for HLM properties was prepared by the WPFC (OECD) Expert Group on Lead-Bismuth Eutectic Technology. A brief review of this compilation is proposed in the present article. A set of correlations for temperature dependence of main thermodynamic properties of Hg, Bi, Pb and Pb-Bi(e) and EOS based on a modified Redlich-Kwong equation are presented.
