CARR铱源试验靶件设计和试验验证
Design and Test Verification for 192Ir Test Target in CARR
-
摘要: 为配合中国先进研究堆（CARR）铱源辐照生产项目，设计制造了铱源试验靶件，对试验靶件的设计参数、结构尺寸进行了介绍。在堆外使用专门的传热装置模拟铱源靶件的外部和内部传热工况，测量了用于模拟辐照罐壁面温度和样品温度的传热装置的壁面温度和内部温度，结果验证了热工分析方法是合适的。入堆试验靶件由含有铱片样品的辐照罐和等量发热的模拟罐组成。堆内试验获得的数据综合验证了试验靶件物理热工的分析结果，这个结果可对CARR铱源辐照生产安全评审提供依据且偏于安全。Abstract: The 192Ir test target was designed and manufactured in order to support the project of 192Ir irradiation production in China Advanced Research Reactor (CARR). Design parameters and structural dimensions of test target were described. The special heat transfer device was used to simulate outer and inner heat transfer conditions of the test target. The wall temperature and inner temperature of the heat transfer device were measured, which simulated the wall temperature of capsule and the temperature of specimens in capsule. The results prove that the thermal analysis method is suitable. The in-pile test target contains the capsule with specimens and the simulating capsules with equivalent heat transfer conditions. Data obtained from in-pile tests verify the results of physical and thermal analysis comprehensively, which can provide a basis for safety evaluation of 192Ir irradiation production in CARR and are conservative.
