Preliminary Hazard Analysis of Uranium Hexafluoride Accident

Abstract

Uranium hexafluoride (UF6) accident is a typical accident in the nuclear fuel cycle. It combine radioactive and chemical hazards, so it is necessary to attach great importance to the UF6 accident. This paper analyzed and summarized the possible accident scenarios, causes and consequences, and classified the UF6 accident risk factors, and put forward corresponding preventive and emergency measures. Preliminary hazard analysis of the accident can help us better understand the accident process, so we can takes steps for corresponding risk factors in advance, and prevent it will not be developed into an accident, so than we can obtain the effect of nip in the bud.
