Conceptual Studies of Design Scheme for Steam Generator in FBR

Steam generator (SG) is one of the most important equipment in the heat transport system of China experimental fast reactor (CEFR). As per design requirements for improving economics and enhancing safety, it is necessary to make optimization analysis on various key aspects of SG. Many basic parameters were discussed in this paper, such as the design input of SG, tube-length, tube specification and the number of tubes, etc. The optimization analysis provides valuable suggestions about the number of tubes, tube-length, the heat transfer area of the margin and tube specification for the SG in its design life.
