中国先进研究堆(CARR)192Ir源辐照生产的关键要求是在反应堆稳态运行时所设计的辐照罐外表面不能发生欠热泡核沸腾,同时辐照罐内部部件的温度满足设计要求。堆内试验利用实际的辐照试验件,测量辐照靶罐的壁面温度。利用获得的数据校验192Ir源靶件物理和热工计算的结果,并为同位素靶件的辐照安全分析提供依据。同位素靶件设计在水冷同位素孔道内辐照,堆内靶件测温试验也在此孔道中进行。设计了1套用于堆内测量辐照靶罐壁面温度的试验件,在9个试验件上安装热电偶,把
China Advanced Research Reactor (CARR) 192Ir source irradiation production of the key requirement is that the steady operation of the reactor can not be designed on the outer surface of the canister underfire bubbling nuclei, while the internal temperature of the irradiated tank to meet the design requirements. In-reactor test The actual irradiation test piece is used to measure the wall temperature of the irradiated target tank. The acquired data were used to verify the results of physical and thermal calculations of 192Ir source targets and to provide a basis for radiation safety analysis of isotope targets. The isotope target is designed to irradiate in the water-cooled isotope pore tunnel, and the temperature measurement test of the target in the reactor is also carried out in this tunnel. A set of test pieces for measuring the wall temperature of the irradiated target tank in the reactor was designed. A thermocouple was installed on the nine test pieces.
