JMCT的高浓铀模型验证计算北大核心CSCD

为了对JMCT程序的准确性和适用性进行验证,从国际临界基准库中选取了56个模型,通过使用JLAMT程序进行建模,然后利用JMCT程序计算了模型的有效增殖因子,并与基准值、MCNP程序计算结果进行对比。计算结果表明,JMCT计算值基本都在基准值的3倍标准差以内,且JMCT计算结果和基准值的相对偏差基本都在2%以下。在一定程度上验证了JMCT程序的准确性和适用性,为后续JMCT程序的使用验证提供借鉴。

The validation and calculation of highly enriched uranium models in JMCT

To verify the accuracy and applicability of JMCT program, 56 models are selected from the International Handbook of Evaluated Criticality Safety Benchmark Experiments. Models are established in JLAMT, and the effective multiplication factors are calculated by JMCT and compared with the reference values and MCNP calculation results. The results show that the calculated values of JMCT are generally within three standard deviations of the reference values and the relative deviations between the JMCT calculation results and the reference values are generally less than 2%. The study has verified the accuracy and applicability of JMCT program to a certain extent, and it provides a reference for the subsequent application and verification of JMCT.
