A graph-theory based software has been prototyped to decompose a large-scale plant design problem represented as a bipartite graph of design conditions to be met and design specifications, and to derive inter-dependencies of the decomposed sub-problems. This software has been validated by application to a simplified model of the prototype fast breeder reactor (FBR)"Monju". The main purpose of this research is to take over engineering knowledge obtained in design, construction, operation and maintenance of "Monju", in order for future constructions of FBRs. The function of this software is focused on inter-relations of each specific engineering judgment whether the target condition is satisfied by relevant specifications.
