Abstract
Tubesheet structures utilized in heat exchangers have complex perforated portions. For design analysis of these structures, axi-symmetric models with equivalent materials of perforated plate are conventionally adopted to simplify perforated portions. Double-wall-tube steam generators expected for commercial FBRs require new type of tubesheets, where conventional design methods are not applicable. Therefore, JAEA started R & Ds to develop a design by analysis method for these structures. This paper reports on the mechanism of thermal stress developments in new tubesheets with an associated paper.
