| Popis: |
The austenitic Alloy-800 steel is a structural material candidate for the steam generators of nuclear power plants, including the sodium cooled breeder reactors (1). In this case the Alloy-800 is exposed to the sodium environment of the secondary heat transfer system coupled to the AISI type 316 or 304 stainless steels generally employed for the intermediate heat exchanger components. For this all-austenitic bimetallic system the corrosion of the materials and the consequent mass transfer are not of relevant importance in the normal service conditions (good technological purity of the sodium and temperatures below 550 °C). However a certain carbon (or nitrogen) interstitial transfer may occur because of the thermal gradients and the different nature of the alloys of the loop; a general carburization could also arise because of the presence of possible carbon sources during the plant running (2). |
