| 摘 要： | 本文主要介绍了核临界事故的有关概念、临界事故的释能过程及释能大小、以及临界事故的破坏力等事故特征，并分三方面：瞬发辐射、工作场所的污染和裂变产物向环境的释放，详细介绍了临界事故的辐射后果。文中指出，核燃料加工或处理工厂发生的核临界事故的放射性释放对环境和公众的影响较小，核临界事故的主要危险来自瞬发射线的外照射。本文可以使我们对核临界事故有一个正确的认识，有助于对可能发生的核临界事故作出恰当的应急响应。

| Abstract: | This paper describes some concepts, the process and magnitude of energy release and the destruction of the nuclear criticality accident and also describes the radiation consequence of criticality accidents from three aspects: prompt radiation, contamination in working place and release of fission products to the environment It shows that the effects of radioactivity release from criticality accidents in the nuclear fuel processing plants on the environment and the public is minor, the main danger is from the external exposure of prompt rays The paper make as have a correct understanding of the nuclear criticality accident and it would be helpful to take appropriate emergency response to potential criticality accident.
