摘　　要：由于模块式高温气冷堆 (MHTGR)是燃烧 Pu的一种选择 ;Th燃料循环可以限制 Pu的产生和减少高放废物 ,因此研究了在 Th 燃料循环模块式高温气冷堆(PBMHTGR)中燃烧 Pu的物理特性。PBMHTGR初装燃料元件中 Pu的同位素的含量与现行的生产能量堆模块式高温气冷堆 (EPMHTGR)相同 ,考虑反应性的要求 ,加入了2 3 3 U。利用 VSOP程序分析这两个堆的物理特性。结果表明 ,PBMHTGR能够燃烧掉同等功率 6个以上 EPMHTGR产生的 Pu。这表明 ,在 Th燃料循环 MHTGR中 。The modular high temperature gas cooled reactor (MHTGR) can be used to burn plutonium in a thorium-based fuel cycle to reduce high-level radioactive wastes. This paper studies the physics of a thorium-based plutonium-burning modular high temperature gas cooled reactor (PBMHTGR). The initial composition of the plutonium isotopes in the fresh fuel element was the same as that in the spent fuel from the energy-producing modular high temperature gas cooled reactor (EPMHTGR) with 233U used as fuel to supply reactivity. The physics of the two reactors was analyzed using the VSOP code. The results show that one PBMHTGR can burn the plutonium produced by more than 6 EPMHTGRs and suggest plutonium can be burned in the MHTGR using a thorium-based fuel cycle
