Spallation target visual auxiliary system and method based on GPU hardware acceleration

Abstract

The invention discloses a spallation target visual auxiliary system and a spallation target visual auxiliary method based on GPU hardware acceleration. The spallation target visual auxiliary system is characterized in that: firstly, a geometrical modeling module establishes a module by virtue of a visual method, so that direct conversion of a common CAD module to an MCNP module is completed; secondly, a grain flow simulative transportation module, based on a molecular dynamics algorithm, realizes blending GPU hardware acceleration to visually stimulate movement, in various containers, of grains, and to output associated physical quantity; thirdly, a high-energy Monte Carlo computing module develops a simulation program of intermediate-high-energy atomic nucleus spallation reaction in a GPU edition, so that nuclear reaction processes of particles such as neutrons, protons and the like in an ADS (accelerator driven sub-critical system) spallation target and atoms in a target material can be efficiently stimulated. The modeling module has the advantages of visually generating a three-dimensional model and quickly converting the three-dimensional model into an input file which can be identified by MCNP. The grain flow module and the high-energy Monte Carlo computing module adopt the concurrent thought, so that the computing can be accelerated by GPU. Very critical effect on the design and the stimulation process of the spallation target is achieved.

Description

technical field [0001] The present invention is under the special project of "future advanced nuclear fission energy"-ADS transmutation system, using GPU hardware acceleration to perform geometric modeling, particle flow simulation transportation, high-energy Monte Carlo calculation and visual processing of related calculation results for spallation target simulation. Background technique [0002] In the current society, fossil fuels can no longer meet the energy needs of the existing society. Through people's continuous innovation, many new energy sources have emerged that can relieve the pressure of petrochemical energy. Nuclear energy has become an outstanding representative of new energy sources. However, nuclear energy also leads to new problems: the worldwide problem of disposal of large amounts of nuclear waste. Taking my country as an example, when the installed capacity of nuclear power reaches 80-100 million kilowatts in 2030, the cumulative accumulation of spent f...

However, nuclear energy also leads to new problems: the worldwide problem of large amounts of nuclear waste disposal

The disadvantage is that although it is relatively general, it cannot be applied to large-scale particle target modeling. China Academy of Engineering Physics and Southwest University of Science and Technology mainly conduct secondary development based on UG commercial software to realize the conversion from CAD to MCNP model, which is still in the research stage
