The paper presents review of studies for sodium-water reaction phenomena, water leak propagation process, evaluation of SG safety, and development of SG tube material for an LMFBR. The paper also presents Alloy 800 wastage characteristics studied with the SWAT-2 small leak sodium-water reaction test loop (OEC, PNC, Japan) and their comparion with those of 9Cr-ferritic steel. In regard to the latter wastage characteristics, this is the first time to show the data of Alloy 800 and 9Cr-ferritic steel wastage obtained from SWAT-2. The results revealed that Alloy 800 has the highest resistance against sodium-water reaction wastage.
