Abstract

The invention provides a neutron transport acceleration method, electronic equipment and a computer readable storage medium, and the method comprises the steps: building a multi-group gCMFD equation equivalent to an initial neutron transport equation based on an initial parameter set of the neutron transport equation; performing iterative acceleration processing on the neutron transport equation through the multi-group gCMFD equation in a spatial dimension until iteration meets a first convergence condition, and establishing an equivalent single-group gCMFD mode equation; and performing iteration acceleration processing on the multi-group gCMFD equation through the single-group gCMFD equation in an energy dimension until iteration meets a second convergence condition. According to the technical scheme, the equivalence between the multi-group gCMFD equation and the neutron transport equation and the equivalence between the single-group gCMFD equation and the multi-group gCMFD equation and the stability of acceleration calculation are strictly guaranteed, neutron transport calculation can be accelerated more quickly, and the overall calculation efficiency is improved.

Description

【Technical field】 [0001] The present invention relates to the technical field of neutron transport, and in particular, to a neutron transport acceleration method, an electronic device and a computer-readable storage medium. 【Background technique】 [0002] With the rapid development of high-performance computing clusters, the use of refined models and high-fidelity numerical methods to directly solve the neutron transport equation has become a realistic and feasible computing solution. However, the whole-core refined neutron transport calculation is bound to face the challenge of huge computational scale, especially the computational time-consuming process. If the actual engineering design is considered again, it is faced with multiple layers and repeated iterations, which makes the calculation time increase geometrically. Taking the full-core neutron transport calculation of a typical pressurized water reactor as an example, its three-dimensional core model contains about 1...
