"Working Group for System Design of Piping Bellows Expansion Joints" is an organization which was established for the purpose of developing piping bellows applicable to the primary cooling piping system of FBR by performing total evaluation on design, manufacture, inspection technology, material, reliability and safety. Research and investigation concerning the piping bellows in general have been carried out every year by this working group composed of PNC staff since the working group was organized under "FBR Piping Bellows Expansion Joints Section Meeting" in 1983. The outline of the works performed by the group in 1988 and 1989 is as follows. (1)Investigation for the design of FBR Demonstration Plant. (2)Concept on arrangement of components and piping of primary coolant system. (3)Investigation for arrangement of components and piping in containment vessel of diameter 45m. Design using arrangement of components and piping with bellows in containment vessel of diameter 45m was proposed on the basis of reserch and investigation concerning the piping bellows carried out in l988 and 1989. We are planning to make effort to reduce material weight and volume by farther investigating and analysing the proposed design.
