核数据是核装置积分参数计算的不确定度的主要来源之一,研究核数据的不确定度在核装置积分参数计算中的传递、评估积分参数的不确定性,对评估核装置设计的不确定性、改进设计程序和核数据具有重要意义。聚变谱屏蔽基准装置是一类重要的核装置,主要用于测试和检验聚变核数据 Nuclear data is one of the main sources of uncertainty in the calculation of integral parameters of nuclear devices. It studies the transfer of uncertainty of nuclear data in the calculation of integral parameters of nuclear devices, evaluates the uncertainty of integral parameters, Certainty, improvement of design procedures and nuclear data are of great importance. Fusion spectral shielding reference device is an important class of nuclear devices, mainly for testing and verification of fusion nuclear data
