| 摘 要： | CENDL-3是中国评价库CENDL的最新版本,通过采用群常数制作程序系统NJOY及反应堆栅元计算程序WIMSD5A和蒙特卡罗程序MCNP对CENDL-3库进行了包括热堆和快堆的基准装置的检验计算,并将检验结果与实验结果和其它库的计算结果进行了比较和分析。表明CENDL-3库中铀同位素的检验结果是相当不错的;由于裂变谱的改进,钚同位素的检验结果也有了相当好的改进;尽管9Be的检验结果有了明显改进,但计算的keff与其它库相比仍有点偏低。

| Abstract: | CENDL-3, the newest version of China Evaluated Nuclear Data Library has been finished, and distributed for some benchmarks analysis recently. The processing was carried out using the NJOY nuclear data processing code system. The calculations and analysis of benchmarks were done with Monte Carlo code MCNP and reactor lattice code WIMSD5A. The calculated results were compared with the experimental results based on ENDF/B6. In most thermal and fast uranium criticality benchmarks, the calculated keff values with CENDL-3 were in good agreements with experimental results. In the plutonium fast cores, the keff values were improved significantly with CENDL-3. This is duo to reevaluation of the fission spectrum and elastic angular distributions of 239Pu and 240Pu. CENDL-3 underestimated the keff values compared with other evaluated data libraries for most spherical or cylindrical assemblies of plutonium or uranium with beryllium. |
