~(233)U中子诱发裂变产额、产额能量关系和瞬发中子谱在Th/U燃料循环的核能开发中具有重要的意义。本工作收集评价了n+~(233)U产额的实验数据,并在多模式无规颈断裂模型的基础上,通过简化位能曲面的表示方式,加入温度相关的壳效应能,建立了n+~(233)U的唯象模型。利用该模型和评价得到的实验数据,研究了0~20 MeV n+~(233)U裂变产物的质量分布和产额能量关系,计算得 The ~ (233) U neutron-induced fission yield, the yield-energy relationship and the instantaneous neutron spectrum are of great importance in the nuclear energy development of the Th / U fuel cycle. In this work, experimental data of n + ~ (233) U yield were collected and based on the multi-mode random neck fracture model, the temperature-dependent shell effect energy was added by simplifying the expression of potential energy surface to establish n + The phenomenological model of ~ (233) U. Using the model and the experimental data obtained from the evaluation, the relationship between the mass distribution and the yield energy of 0 ~ 20 MeV n + ~ (233) U fission products was studied and calculated
