Corrosion issues in high temperature gas cooled reactor (HTR) systems

Description

The corrosion issues in high temperature reactors (HTRs) are probably less critical compared to such issues in other nuclear reactors. Nevertheless it is important to take them into account adequately. In this chapter we consider the following items: structural metallic material corrosion in high temperature conditions; graphite corrosion (mainly oxidation) behaviour in high temperature environments; the corrosion of the PBMR spent fuel tank in severely corrosive environments; the interaction between UO2 and C layer into the CP. The chapter ends with a short description of future trends related to the corrosion aspects specific to the HTR.
