| 中文摘要 | 球床式高温气冷堆(HTR)球流运动存在混流的现象,它会对功率峰值等堆芯参数发生影响。该文开发了专门的混流模拟方法,在原球床高温气冷堆分析程序VSOP的基础上开发了新的程序系统MFVSOP。新程序通过设定不同的混流比例可模拟球床式高温气冷堆堆芯每个流道与相邻流道的混流,实现其与堆芯物理、热工、燃耗等计算耦合并有能力分析球流混流运动对堆芯燃耗分布、功率分布等参数的影响。对于研究球床式高温气冷堆的运行特性及不确定性分析提供了有力的计算工具。; The pebbles flowing in a pebble bed high temperature gas cooled reactor(HTR)mix between channels as they flow through the reactor,which may affect the reactor parameters such as the power peak factor.This paper describes a method to model the pebble mixing.This mixing model is added to the VSOP code to model the pebble mixing in the pebble bed.This new code package can simulate the pebble mixing between flow channels with a specified mixing coefficient in a coupled model of the pebble flow,physics,thermal hydraulics and burnup.Therefore,the model can be used to investigate the effect of pebble mixing on the core burnup distribution,power distribution and other characteristics.This code is a powerful tool for analyzing HTR operating characteristics and uncertainty. |
