摘要: 本文用数值计算法计算了聚变-裂变混合堆燃料元件包壳的热应力分布。计算结果表明由D-T周期性燃烧引起的交变热应力比裂变堆稳态运行的热应力问题严酷得多。热应力的变化规律与温度循环范围及包壳的壁厚成正比。保证安全可靠运行的关键是合理设计热循环的温度范围。

Abstract: In the fusion--fission hybrid reactor, the alternating thermal stresses of fuelelement cladding are much more serious than steady operating fission reactor,because of the D--T periodic burning. The thermal stresses are directly proportionalto the temperature cycling region and thickness of cladding. The key to the safeand reliable operation is reasonable design of temperature cycling region.
