基于B&W临界实验基准题的先进中子学组件程序KYLIN V2.0的验证与确认

KYLIN V2.0 is an advanced neutronics component program independently developed by the Nuclear Power Institute of China. The program uses subgroup resonance method, characteristic line method and Chebyshev rational approximation method to calculate resonance, transport and burnup, so as to provide multi-group cross-section library. This paper uses B&W critical experiment benchmark task to verify and validate the KYLIN V2.0 program, including 21 examples of B&W1484 critical benchmark task and 23 examples of B&W1810 critical benchmark task. The calculation results show that the calculation results of KYLIN V2.0 program are in good agreement with the measured data, which verifies that KYLIN V2.0 program has good calculation accuracy and non-uniform calculation ability.
