From national topical meeting on mathematical models and computational techniques for analysis of nuclear systems: Ann Arbor. Michigan, USA (8 Apr 1973). In mathematical models and computational techniques for analysis of nuclear systems. The discussion of multidimensional reactor calculations is restricted to static problems. It is attemptod to place the current mathematical and computational methods development efforts into an appropriate perspective by giving a short review about the accuracy requirements and prescnt capabilities of predicting physical parameters for fast and thermal reactors. The mathematical properties of the transport and diffusion equations and of their exact solutions are considered and their relevance to the development of numerical methods is sketched. The theoretical foundation of numerical solution methods is discussed. Typical computational difficulties based on characteristic physics properties of various reactor types are presented and the benefits, difficulties, and the reliability of several computational methods are reviewed. In addition, new methods and possible future trends are discussed. Finally some of the outstanding mathematical and computational problems for fast and thermal power reactor calculations are mentioned. 131 references. (auth)
