Abstract

In the literature the corrosion of stainless steel in liquid sodium is extensively reported. Less is known about the deposition behaviour of the elements from stainless steel, that is Fe, Cr, Ni and Mn. It is conceivable that the deposition behaviour of these elements as a function of the relevant parameters provide information with respect to the corrosion and mass transport mechanism of the steel. This was the main reason to study the deposition behaviour of the above mentioned elements. In addition the deposition behaviour of Co was studied, which together with Mn are the main radionuclides released by the canning materials. The parameters taken into account were the temperature, the oxygen level and the downstream position. As only isothermal loop systems were at our disposal, a driving force different from a thermal force had to be created. To that end various metals as Co, Ni and Fe (in two runs Mn as well) were taken as specimens to getter the steel elements. Thus, the elements to be gettered are released by the loop system, except for Co, and by the specimens, except for Cr and in most runs for Mn.
