摘　　要：ＵＦ６是核燃料生产过程中一种重要的中间产品，生成于铀同位素分离过程中，因此，ＵＦ６大量向环境释放是核燃料生产厂运行期间可能发生的一种潜在事故。为了评价ＵＦ６释放的事故后果，本文对ＵＦ６释放的特点作了讨论，并以某厂的环境和气象条件为例，估算了事故性ＵＦ６释放可能导致的辐射环境影响，以说明估算程序和应考虑的问题。UF 6, as a interim product of nuclear fuel manufacture, arises from uranium isotope isolation process. A substantial amount of UF 6 releasing to the environment would lead to potential accidents during operation of nuclear fuel plant. To evaluate accidental consequences of UF 6 releases and with view of explaining estimation procedures and resolving some problems,discussions are made on the characteristics of the releases and estimates carried out for environmental impact of accidental releases on the basis of the environmental and meteorological conditions on a plant site.
