为开展中子核数据评价工作,“十一五”期间中国原子能科学研究院研制了一套中子核数据基准检验实验系统,并利用中子飞行时间技术测量了中子穿过板状238U样品的泄漏中子时间到达谱,为CENDL3.1评价数据库中238U数据的改进提供了宝贵意见。由于该实验没有专门设计布局前级
In order to carry out the evaluation of neutron nuclear data, China Institute of Atomic Energy developed a set of neutron nuclear data benchmarking test system during the 11th Five-year Plan period and used neutron time-of-flight techniques to measure the neutron penetration through the plate The leakage neutron time-of-arrival spectra for the 238U sample provided valuable input for the improvement of the 238U data in the CENDL 3.1 evaluation database. Because the experiment did not specifically design the layout of the previous stage
