Nitrogen Transfer in Austenitic Sodium Heat Transport Systems

  • Stuart A. Shiels

Transfer of the interstitial elements, carbon and nitrogen, in high-temperature sodium heat transport systems is a well-recognized phenomenon which has been studied extensively over the years. There are many recorded examples of carbon and nitrogen loss from, and pick-up by stainless steels exposed to high temperature sodium under a variety of conditions. Carbon transfer has, however, received the major share of attention. In-depth studies, sponsored by the Department of Energy at the Westinghouse Advanced Reactors Division and at the Argonne National Laboratories, have expanded the knowledge of this phenomenon to a stage where predictive equations are now routinely used for the prediction of end-of-life carbon levels in structural components.
