Abstract

Visualization studies and temperature measurements were made in a granular bed of nickel or copper particles as a contribution to the understanding of local dryout leading to corrosion of tubes in steam generators of pressurized water nuclear reactors. The granular beds filled an annular space between two concentric glass tubes or the space between a square array of nine tubes. Water filled the voids and the space above the bed and was brought to boiling by a heat flux through the wall of the tubes. It was established that counter flow between the liquid and the vapor escaping through the voids of the bed can be established over a certain height of a ″wetted region″ only. Corrosion is expected in the dryout region or at its border to the wetted regions by concentration of aggressive chemical species dissolved in the water.
