为进行材料在高γ释热区的辐照考验,研制了模块式套管型随堆辐照考验装置(MTIR)。该随堆辐照考验装置具有辐照温度测量和调节功能,在高γ释热率条件下能够对试验段进行强化冷却。堆内验证试验表明,该装置能够实现材料样品的辐照考验指标,可使高通量工程试验堆(HFETR)内层辐照孔道得到有效利用,缩短材料堆内辐照试验周期,提高HFETR辐照能力。 In order to test the irradiation of materials in the high γ-heating zone, a modular casing-type reactor with irradiation test (MTIR) was developed. The on-stack irradiance test device has the function of measuring and adjusting the irradiation temperature, and can perform intensive cooling on the test section under the condition of high γ heat release rate. The in-pile verification test shows that the device can achieve the irradiation test index of the material sample, which can effectively utilize the irradiation tunnel in the inner layer of the high-throughput engineering test reactor (HFETR), shorten the radiation test period in the material reactor and improve the HFETR radiation According to ability.
