| 摘 要： | 采用ORIGEN-2分析了间断运行条件下船用堆放射性核素的累积过程。根据放射性核素累积的影响因素,将核应急早期剂量贡献较大的13种放射性核素分为4类,并得出了4类核素间断运行条件下累积过程的表达式,总结出了相应的累积规律;计算了各核素的衰减时间,并根据其衰减时间,将上述核素分为4组,给出了每组核素的影响持续时间。

| Abstract: | ORIGEN-2 was used to analyze the accumulation of radionuclide in the marine reactor under discontinuous operation.According to the factors affecting the radionuclide accumulation,13 kinds of nuclides with chief contribution to the early dose were divided into 4 categories.Their expressions ware obtained with the corresponding accumulation characters summarized.The time that each radionuclide attenuates from dynamic equilibrium to zero,namely attenuation time,was calculated based on which the 13 radionuclides were classified into 4 groups.Each group was provided with the influence duration. |
