多种危险并存于核燃料元件制造厂，因此有必要对核燃料元件厂进行风险分析。目前有多种风险评估方法适用于核燃料元件制造厂风险评估，本文选取HAZOP和LOPA方法，对核燃料元件制造厂风险评估中的最重要工艺UF6气化工序进行了分析。 HAZOP分析得到了可能产生严重后果的工艺偏离。LOPA分析得到了针对工艺偏离所采取的独立保护层措施所降低的风险和 UF6气化工序的残余风险。

A variety of hazards coexist in nuclear fuel fabrication facilities , so risk assessment is necessary .There are a variety of risk assessment methodologies for risk assessment of nuclear fuel fabrication facilities .HAZOP and LOPA method were select‐ed for UF6 vaporization process which is the most important in risk assessment of nucle‐ar fuel fabrication facilities . The process deviations which have serious consequences were obtained by HAZOP .The risk reduced by independent protection layers and the residual risk of UF6 vaporization process were obtained by LOPA .
