HFETR^6LiD转换器热工安全分析研究

The Thermal Security Analysis and Research of the ~6LiD Converter in the HFETR

6LiD转换器在堆内辐照时,样品与转换器包壳会产生热量,因此对转换器的热工安全进行了分析研究,结果表明:将转换器布置在HFETR辐照孔道,转换靶芯体最高温度为83. 55oC,包壳温度在80oC左右,样品中心温度在59oC左右,都在安全限值以下,低于其熔化温度,满足热工安全要求。安全性能分析表明,转换器可以在HFETR内安全运行。

When the^6LiD converter was put into the core of the reactor,the sample and the convert would generate energy,so the thermal security of the converter should be analysed.The results showed:when the converter was put into the core of the reactor,the highest temperature of converter’s core part was83.55℃,and the highest temperature of cladding was about80℃,and the highest temperature of the sample was about59℃.All the above temperature was under the melt temperature.The security analysis showed the converter could run safely in the HFETR.
