Description

Based on the ENDF/B-VII. 0 nuclear evaluation data library, an improved multi-group cross section data library NECL2.0 was produced for Bamboo-Lattice code by using the nuclear data processing code NJOY and LATTICE-PRE. The results based on benchmark and numerical analysis show that the calculation results of infinite multiplication factor kinf, fission rate distribution and few-group homogenized cross section by using NECL2.0 library agree well with the corresponding reference values. Considering the resonance of Ag-In-Cd can increase accuracy of kinf by 1000 pcm. Compared with reference values, the maximum relative deviation of fission rate reduces from-0.97% to-0.53%. Considering the resonance of zirconium in cladding can improve the accuracy of kinf by about 60 pcm. (authors)
