The interaction of caesium hydroxide vapour with 304 stainless steel and Inconel-600

Technical Report:

Abstract

Experiments have been conducted to characterise the oxidation of 304 stainless steel and Inconel-600 and their interaction with caesium hydroxide vapour under the conditions expected to occur in the primary circuit region of the Phebus-FP experiments. Oxide deposits formed on 304stainless steel at 700{sup o}C in a steam atmosphere were shown to be adherent, with no evidence of spallation. The reaction of caesium hydroxide vapour with Inconel-600 in steam at 700{sup o}C was a factor of two to three less than the equivalent reaction with stainless steel. The degree of reaction appears to be related to the extent of oxide formation, with a thinner, more compact, surface oxide formed on Inconel-600 than 304 stainless steel. These results indicate that retention in Inconel pipework in Phebus-FP would be less than with an equivalent stainless steel system, thus ensuring more neutral conditions and greater transport of material to the containment vessel.
