Abstract

The invention provides a fast reactor isomorphic component full-reactor core rod bundle-sub-channel mapping construction method and system. The method, into which concepts as a meta-structure, alignment sum, opposite edge sum and co-alignment sum are introduced, comprises the steps: firstly constructing a component-level rod bundle-sub-channel mapping relation, and then constructing a reactor core-level component-component mapping relation. The method can be used for automatically constructing fast reactor whole-reactor core rod bundle-regular sub-channel mapping or whole-reactor core rod bundle-irregular sub-channel mapping which at least comprises a rod bundle and is provided with an assembly. The method is mainly applied to a, inquiring rod bundles and surrounding sub-channels around aknown rod bundle; and b, inquiring sub-channels and surrounding rod bundles around the known sub-channels. The problems that a mapping model constructed by an existing rod bundle-sub-channel mapping construction method only aims at a single fast reactor hexagonal assembly and the existing rod bundle-sub-channel mapping construction method is not suitable for fast reactor whole-reactor core rod bundle-sub-channel mapping construction can be solved.

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...
