2400 MW先进高温堆的临界与燃耗计算

Criticality and Burnup Analysis of 2 400 MW AHTR

摘要: 本工作对2 400 MW 棱柱先进高温堆的临界及燃耗进行了研究。所采用的计算工具为SCALE5.1中的TRITON模块。计算中选用了3种燃料石墨比分别为27∶65.4、30∶62.4及33∶59.4的模型。经计算，得到了这3种模型的堆芯寿期分别为1 260、1 350及1 320有效满功率天（EFPDs），对应的燃耗深度为139、134和125 GW·d/MtU。

Abstract: The criticality and burnup analysis was performed for the 2 400 MW AHTR, using the computer codes TRITON in SCALE 5.1. Three different models, whose fuel-to-graphite ratio are 27∶65.4, 30∶62.4 and 33∶59.4, were selected for the analysis. The core life for these three models was predicted to be 1260, 1350 and 1320 effective full power days (EFPDs), and the corresponding burnups are 139, 134 and 125 GW·d/MtU, respectively.
