摘要
由在辐照孔道内实验装置的实测数据,得到了辐照罐的γ释热率。根据分析计算,得出了确定辐照中气隙宽度的计算式。采用了增强周向导热能力及用电加热调节温差的设计思想。所设计的辐照罐即使在要求三种不同的辐照温度的情况下,成功地满足了辐照温度及温差的要求。设计温度的相对误差小于10％。
The rate of γ-heat generated from an irradiation capsule can is obtained by measuring an experimental device Placed in the irradiation channel. According to the analysis calculation the formula for determining the width of the gap which is the main thermal resistance of an irradiation capsule can is obtained. The ideas of increasing the peripheral conductivity and using electrical heaters to adjust the temperature differences are adopted. The irradiation capsule can design successfully meets the requirements of irradiation temperatures and temperature differences even in the case where three different temperatures are required. The relative error of the designed temperature is less than 10%.
