高通量工程试验堆80盒元件堆芯研究

The Study on 80 Fuel Assemblies Core for HFETR

通过理论分析和运行结果比较了高通量工程试验堆８０盒、６０盒工件堆芯性能。结果表明，ＨＴＦＴＲ８０盒元件堆芯在允许功率、材料辐照和单晶硅掺杂、钼锝同位素生产等方面与６０盒元件堆芯性能相同。８０盒元件堆芯更有利于５００ｋＷ回路入堆后堆的运行，有利于大幅度提高高比度＾６０Ｃｏ医疗源产量和元件利用率。

The core performance of 80 and 60 fuel assemblies of high flux engineering test reactor (HFETR) have been compared by theoretical analysis and operating results. These results show that the core performances of 80 fuel assemblies are the same as that of 60 fuel assemblies in the following aspects; the permission power of core, the irradiation test of materials, the transmutation doping of single crystalling silicon, the production of Mo-Tc isotopes, etc. The core of 80 fuel assemblies is more convenient in operation after 500k W test loop installed, in greatly raising the production of 80Co source with high specific radioactivity intensity and the usagt of fuel. Compared to the production of 50Co source of 60 fuel assembles, 80 fuel assemblies can increase more than 3. 8 millions yuan par year.
