Abstract: Background

The high-fidelity particle transport numerical simulation for nuclear facility requires accurate and efficient source particles distribution.


This study focuses on reviewing and analyzing the distribution feature of source particles intuitively in nuclear facility and presents a visual analysis method for source particles.


Based on self-adaptive segmented tree and pre-build geometry library, the features of geometry and rendering attributes were extracted to dynamically create the segmented trees. Then, over million source particles were shown in the form of two-dimensional and three-dimensional visualization. Finally, this method was verified on neutron source modeling and neutron collimation device design for shielding analysis of VENUS-3 reactor.


The results show that the proposed method is helpful for users to complete high fidelity modeling and the design and optimization of nuclear facilities.


To a certain extent, it can improve the efficiency and correctness of modeling during the procedure of calculation.

Key words: Nuclear devices, Transport simulation, Source particles visualization, Self-adaptive segmented tree
