本文介绍γ射线加热式高温水堆内辐照装置的原理,设计方法和结构特点。该装置主要用于材料在高温水中的辐照实验。堆内实验表明,使用这种辐照装置,在200℃—300℃的范围内,辐照样品温度能达到要求值并长期保持稳定。
This article introduces the principle, design method and structural characteristics of the irradiation device in γ-ray heating type high temperature water reactor. The device is mainly used for irradiation experiments of materials in high temperature water. In-reactor experiments show that with this type of irradiation device, the temperature of the irradiated sample can reach the desired value and remain stable over a long period of time in the range of 200 ° C to 300 ° C.
