摘　　要：采用蒙特卡罗方法对高通量工程试验堆堆芯内的γ释热分布进行了详细的计算分析和研究,并对堆芯内φ63辐照孔道在不同状态下的γ释热分布进行了详细准确的研究。计算结果表明:堆芯内γ释热功率为3.29MW,燃料元件功率62.8MW,分别占堆芯总功率(70MW)的4.7%和89.7%;3个φ63辐照孔道内单位质量介质γ释热率分别为:G7孔道为3.016W/g,P12孔道为3.733W/g,P15孔道为3.627W/g。本研究为HFETR堆芯及各组件的热工安全分析提供了必要的数据,保证了反应堆的安全运行,节约了反应堆的运行成本,提高了反应堆的经济性。In this paper, γ-Heat distributions in the current High Flux Engineering Test Reactor core and in the φ63 material irradiation channel of HFETR were calculated with MCNP code. The results of the calculation and analysis showed that the γ-Heat power distribution in the current core is 3.29MW, the power of fuel element is 62.8MW, which is respectively 4.7% and 89.7% of the core total power （70MW）. The γ- Heat power distribution of the unit flux media in threeφ63 irradiation channel is as follows： 3.016W/g in G7, 3.733W/g in P12, and 3.627W/g in PIS.
