Examples
- So it is very important for safety evaluation of in - pile fuel elements that we explore the thermal stability of fuel plates
因此，研究燃料元件的热稳定性，对掌握燃料元件的堆内行为和安全评价具有很重要的意义。 - The paper describes the heat treatment at the temperature of 160 , 250 , 350 , 400 , 450 and 500 , the dimension change and microstructural evolution of miniature fuel element plates after heat treatment . the result reveals that : the fuel plates did not deform after 60 days at 160 and 250 , slightly curved after 60 days at 350 and 400 , and heavily curved after 20 days at 450 and so did after 1 day at 500
本论文介绍了微型燃料元件板(芯体u _ 3si _ 2 - al ，包壳为6061铝)的热稳定性实验研究，在160 、 250 、 350 、 400 、 450 、 500温度下经过一定的热循环，测定燃料板的变形，进行微观组织分析，结果表明：在160 400范围四个温度循环热处理60天后，燃料板厚度变化均小于0 . 03mm ，在前两个温度下，基本没有变形；在后两个温度下，燃料板稍有卷曲。 - Above 450 , the formation of low density u ( al , si ) 3 phase , together with the release of the impurity gas and fragmentation of u3si2 particles , will cause fuel meat to swell , al matrix to crack and u3si2 particles to invade to clad . as a result , the thickness of the meat increased , the thickness of clad decreased and the deformation of fuel plates increased , and the leakage probability of the radioactive mass increased reasonably
同时，由于芯体膨胀及铀硅颗粒碎裂的综合作用，使u _ 3si _ 2颗粒向包壳侵入，最终使燃料板芯体厚度增加较大，芯体及燃料的体积也显著增加，包壳厚度减薄；高温将加速芯体u _ 3si _ 2颗粒碎裂、芯体开裂、包壳以及燃料板变形，从而使燃料芯体与包壳脱开，最终可能导致放射性物质泄漏。
