Abstract

Liquid lead and lead-bismuth eutectic (LBE) alloys are considered as coolants and spallation targets for advanced nuclear systems. These heavy metals are highly corrosive towards the structural steels due to high solubility of alloying constituents of steels. However, this corrosion can be minimized by controlling the dissolved oxygen concentration in the liquid metals to form a protective oxide layer on the steel surface. This requires an understanding of thermochemical behavior of oxygen in the coolant-steel system. The paper describes data of laboratory studies on Pb-O, Pb-Cr-O and Pb-Fe-O systems.
