ABSTRACT

The alkali metal sodium is used as coolant fast breeder reactors. Accidental spillage of sodium at high temperature from pipes in inert equipment cells or inside reactor cavity can lead to various safety issues in fast breeder reactors due to sodium fire. To prevent the structural concrete from deterioration, a sacrificial layer of limestone aggregate concrete is provided over the conventional siliceous aggregate concrete (Chawla et al. 1985, Pramila et al. 2008, and Das et al. 2009).
