Abstract

The invention discloses a modeling system which is used in reactor design and used for reactor core component design. According to the modeling system, the geometric specificity of a fission reactor core is analyzed, a great amount of repeatedly constructed geometries are adopted, a CAD engineering model and a Monte Carlo calculation model of the fission reactor core are automatically established by establishing parameters, the Monte Carlo calculation model is used for radiating and transporting input of a Monte Carlo calculation program, and the significant physical quantity of the reactor core can be calculated after the Monte Carlo calculation model is obtained. By constantly evaluating the physical parameters of the calculation result, the modeling system can be used for performing repeated iteration correction on a design scheme of the fission reactor core till a reactor core scheme which makes a user satisfactory is made. The modeling system has the benefits that the tediousness that Monte Carlo calculation programs are written and files are input manually is avoided, the whole modeling process is very visible, the probability of mistakes is greatly reduced, and the design time of the reactor core is shortened.

Description

technical field [0001] The invention relates to a reactor core iterative design system based on Monte Carlo calculation, which is applied in the fission reactor core design based on Monte Carlo calculation, and the goal is to quickly and automatically build a fission reactor core CAD engineering model and Monte Carlo calculation Model. Background technique [0002] With the advancement of reactor design and construction technology, various new reactor designs have come out frequently. The Monte Carlo calculation program has been widely used in the conceptual design and engineering design of the core due to its ability to adapt to any complex geometry and accurate calculation results. , and completing the modeling of complex geometry is the core part of writing the input file of the calculation program. At present, the following methods are mainly used: first, manual modeling is time-consuming and labor-intensive, and is prone to errors; second, automatic modeling by script ...
