Abstract

The present invention provides a fast reactor isomorphic component whole core rod bundle-subchannel mapping construction method and system, the method introduces "metastructure", "parallel sum", "opposite side sum" and "co-position sum" and other concepts, the component-level bundle-subchannel mapping relationship is constructed first, and then the core-level component-component mapping relationship is constructed. It can automatically construct fast reactor core rod bundle-regular sub-channel mapping or full-reactor core rod bundle-irregular sub-channel mapping that contains at least one rod bundle and has one component. The main applications are: a. Query around the known rod bundle Bundles and surrounding sub-channels; b. Query known sub-channels surrounding sub-channels and surrounding rod bundles. It can solve the problem that the mapping model constructed by the existing rod bundle-subchannel mapping construction method is only for a single fast reactor hexagonal component, and the existing rod bundle-subchannel mapping construction method is not suitable for the fast reactor core rod bundle- Issue with subchannel map construction.

Description

technical field [0001] The invention relates to the field of nuclear science and technology, in particular to a construction method and system for fast reactor core rod bundle-subchannel mapping construction of isomorphic components of a fast reactor. Background technique [0002] The subchannel model analysis method is one of the important methods for thermal-hydraulic simulation of fast reactors. Its core problem is the subchannel modeling of a single hexagonal component of a fast reactor or the entire fast reactor core (depending on the simulation scale). In the model, the whole assembly or core is divided into several sub-channels, such as Figure 2-Figure 5 shown; axially, the sub-channel is divided into several control volumes, such as Image 6 shown. The fluid flows in such a flow channel, on the one hand exchanges energy and momentum with the surrounding fuel rods, and on the other hand exchanges mass, energy and momentum with the adjacent channel through the imagi...
