A first wall/blanket/shield design and optimization system (BSDOS) has been developed to provide a state-of-the-art design tool for fast, accurate analysis. In addition, it has been designed to perform several other functions: (a) allowing comparison and evaluation studies for different concepts using the same data bases and ground rules, (b) permitting the use of any figure of merit in the evaluation studies, (c) optimizing the first wall/blanket/shield design parameters for any figure of merit under several design constraints, (d) permitting the use of different reactor parameters in the evaluation and optimization analyses, (e) allowing the use of improved engineering data bases to study the impact on the design performance for planning future research and development, and (f) evaluating the effect of the data base uncertainties on the design performance. BSDOS is the first design and optimization system to couple the highly interacting neutronics, heat transfer, thermal hydraulics, stress analysis, radioactivity and decay-heat analyses, tritium balance, and capital cost. A brief description of the main features of BSDOS is given in this paper. Also, results for using BSDOS to perform design analysis for several reactor components are presented.
