摘　　要：为验证DRAGON程序加载WLUP数据库处理钍基燃料问题的可靠性,本文使用DRAGON程序加载WLUP提供的14种WIMSLIB格式核数据库,计算钍基燃料基准问题的k_(eff)并与实验值进行比对,选择IAEA提供的WIMSD程序计算结果作为比对组。结果表明:DRAGON程序计算结果与WIMSD程序计算结果表现出较好的吻合性,处理轻水慢化钍基燃料时,推荐使用endf68gx数据库,其平均相对偏差为0.18%;处理重水慢化钍基燃料时,推荐使用endf71与jendl3gx数据库,其平均相对偏差为0.81%。因此,使用DRAGON程序加载合适的WLUP数据库计算钍基燃料问题具有一定的可行性。In order to validate the reliability of DRAGON code using WLUP library to calculate the thorium fuel benchmark,DRAGON code with 14 WIMSLIB libraries from WLUP was used to calculate the k_（eff）of thorium fuel benchmark and then the calculation result was compared with the experimental results.Meanwhile,the calculation result of WIMSD code provided by IAEA was selected as the comparison.The results show that the calculation result of DRAGON code has good agreement with that of WIMSD code.The endf68 gx library was more excellent with the average relative error of 0.18% when light water moderated thorium benchmark is validated,and endf71 and jendl3gx libraries have the best result with the average relative error of 0.81% when heavy water moderated thorium benchmark is validated.The result indicates that calculating thorium fuelproblems by DRAGON code using appropriate WLUP library is reliable.
