As an extensible platformfor reactor conceptual design, it is very important to study modeling technology and develop somekind of tools to speed up preparation of all classical computing models. This paper introducesthe background of the project and basic conception of digital reactor. MCAM is taken as anexample for modeling and its related technologies used are given. It is an interface program forMCNP geometry model developed by FDS team (ASIPP & HUT), and designed to run on windowssystem. MCAM aims at utilizing CAD technology to facilitate creation of MCNP geometry model.There have been two ways for MCAM to utilize CAD technology: (1) Making use of user interfacetechnology in aid of generation of MCNP geometry model; (2) Making use of existing 3D CADmodel to accelerate creation of MCNP geometry model. This paper gives an overview of MCAM'smajor function. At last, several examples are given to demonstrate MCAM's various capabilities.展开更多

Because of the symmetry and sparsity of thelinear system of equations, a new method of improved Gauss elimination is presented for the solutionof large scale sparse matrices. Comparison of the new method with the classical Gauss eliminationmethod, the Gauss-Seidel iterative method are given. The results show that the algorithm provided isbetter than the others and is suitable for auto-modelling of fluid networks of power plants.展开更多
