Abstract

The conditions of operation of fuel elements in emergency situations with the depressurization of the primary circuit and air ingress the latter are discussed for the pebble bed module reactor. The analytical models of light and heavy corrosion of the fuel elements as well as the criterion conditions that determine the nature of corrosion are given. The local differentialities of surface corrosion of the fuel elements in the pebble bed with a natural convection of gas are evaluated.
