加速器驱动次临界系统的MCNP多群数据库制作及参数敏感性研究
Study on the Processing Methods of Monte Carlo Multi-Group Library and Parameter Sensitivity for ADS
摘要
Abstract
In view of the characteristics of fast neutron share,multiple nuclides resonance and neutron multiplication of liquid lead-bismuth alloy coolant in accelerator driven subcriti-cal system(ADS),a set of MCNP multi-group library processing program for ADS fuel con-sumption analysis was developed. Based on the latest ENDF/B-VII.1 and JENDL40 evaluation database,30 groups P3 multi-group library for ADS was processed.Parameter sensitivity of three parameters including the energy group structure,distribution of neutron scattering angles,(n,2n) and (n,3n) cross section, which had an influence on the calculation accuracy,were studied and tested by the fast neutron spectrum criticality bench-marks and ADS core model.The results showed that the same results with continuous-ener-gy MCNP code were obtained and the speed-up was 1 to 3 times that with the MCNP.关键词
