An integrated multi-functional neutronics calculation and analysis code system:VisualBUS

Abstract

Neutronics calculation and analysis are the bases of reactor physics design,radiation protection,fuel management optimization,nuclear safety analysis,etc.After surveying and evaluating the status and trend of development of neutronics calculation and analysis codes,a network-based integrated multi-functional neutronics calculation and analysis code system has been designed and developed for applications in fusion,fission and various hybrid systems based on the adoption of advanced neutronics calculating approaches and modern computer software technologies.A series of benchmark tests and applications have shown the maturity and effectiveness of the system.This paper gives a brief overview about main technical features of the system,thebenchmark tests and applications.
