SORA原型装置临界实验的基准化分析
Benchmarking Critical Experiment of SORA Mockup
摘要
Abstract
Benchmarking the critical experiments of nuclear assembly is a prerequisite for enriching the International Handbook of Evaluated Criticality Safety Benchmark Experiments.Firstly,the core configurations and critical experiments of the SORA (Sorgente Rapida Reactor) mockup were introduced.Then the uncertainties of experimental keff for fifteen typical critical experiments were evaluated,resulting in the range of 0.002 3-0.002 7,and the biases with their uncertainties for modelization of the experiments were analyzed.Lastly the benchmarking results of keff with uncertainties were achieved.The results of numerical calculation of the SORA model are a little less than the benchmarking results of experiments in which the most relative deviation is less than 1%.The results meet the requirements for the inclusion of the International Handbook of Evaluated Criticality Safety Benchmark Experiments.关键词
