摘要
基于确定论的中子学分析程序在计算氟盐冷却球床高温堆(PB-FHR)时需解决双重非均匀性的燃料球均匀化、燃料球均匀化时出现的泄漏效应及燃料球在堆芯内连续移动与多次通过堆芯的燃料循环模式问题。本文基于DRAGON5与DONJON5程序开发了PB-FHR的燃料管理程序PBMSR,并进行了验证。使用PBMSR对PB-FHR在不同燃料循环模式下进行计算与初步分析,结果显示在多次通过的燃料管理模式下,燃料球的通过次数对最深卸料燃耗影响较小,但对轴向功率分布影响较大。
There are three challenges needed to be solved in pebble bed-fluoride salt-cooled high temperature reactor(PB-FHR)by using the deterministic neutron analysis codes,which are homogenization of double heterogeneity fuel pebble,leakage effect during homogenization and the continuous movement of fuel pebble in the core and multi-pass fuel management mode.Based on DRAGON5 and DONJON5 codes,a PB-FHR fuel management code PBMSR was developed and verified.PBMSR was used to calculate the PB-FHR with different fuel cycle modes.The results show that the number of a fuel pebble passing the core has little impact on the optimal discharged burnup in the multi-pass fuel cycle mode,but has great impact on the axial power distribution.
