摘　　要：为保证反应堆的安全,并对燃料元件的制造加工提出合理可行的要求,从元件制造加工和反应堆运行测量两方面对多层套管燃料元件工程热点因子的敏感性进行了分析。结果表明:流道间隙偏差直接影响元件热源的导出,由此引起的工程热点因子造成的温升较大。For ensuring reactor safety and putting forward reasonable requirements of fuel element manufacture,the sensitivity analysis of engineering hot spot factor for multi-layer tube fuel element was completed from both aspects of fuel manufacture and reactor operation measurement.The result shows that the flow channel deviation is of direct effect on fuel element heat transfer,yielding a higher temperature rise caused by the relevant engineering hot spot factor.
