摘　　要：为解决铅铋堆中^(210)Po的产生及迁移计算问题,基于国际上同类型反应堆该问题的计算方法,开发了可用于铅铋堆^(210)Po的产生及迁移计算的源项程序(LBE-SOURCE)。利用LBE-SOURCE对ATW和CLEAR反应堆冷却剂中^(210)Po的活度、工艺间内Po的活度、人员吸入量进行了计算,LBE-SOURCE计算结果与ATW和CLEAR的计算偏差在0.03%~3.57%,程序计算结果与相应设计报告符合较好。此外,LBE-SOURCE程序已用于铅铋堆中^(210)Po活度及迁移计算,计算结果与国际上同类型、同功率水平反应堆数值接近,解决了铅铋堆设计中的^(210)Po的活度计算问题。In order to solve the calculation of ^(210)Po generation and migration in the lead-bismuth reactor, this paper developed a source term program(LBE-SOURCE) that can be used for the calculation of ^(210)Po generation and migration in the lead-bismuth reactor based on the calculation method of the same type of reactors in the world. The LBE-SOURCE was used to calculate the activity of ^(210)Po in the coolant of ATW and CLEAR reactor, the activity of ^(210)Po in the process room and the intake of personnel. The deviation of the calculation result of LBE-SOURCE and the calculation of ATW and CLEAR is 0.03% to 3.57% in between, the calculation results of the program are in good agreement with the corresponding design reports.In addition, the LBE-SOURCE program has been used to calculate the activity and migration of ^(210)Po in lead-bismuth reactor. The calculation results are close to the values of the reactor of the same type and the power level in the world, which solves thePo activity calculation in the design of the lead-bismuth reactor.
