Based on the recently released ENDF/B-VII.1 library,high temperature neutron cross-section files are generated through SIGACE code using low temperature ACE format files.To verify the processed ACE file of SIGACE,benchmark calculations are performed in this paper.The calculated results of selected ICT,standard CANDU assembly,LWR Doppler coefficient and SEFOR benchmarks are well conformed with reference value,which indicates that high temperature ACE files process...
