Abstract: Uranium hexafluoride (UF6) leakage accidents represent one of the most serious classes of accidents in the gasification process in nuclear fuel manufacturing facilities. Common UF6 leakage accidents include various fault conditions, such as pipeline and valve breakages or ruptures and pipeline blockages. By establishing goal-oriented (GO) operators that can represent multi-fault states, this study estimates the probabilities of various fault states corresponding to UF6 leakage accidents in the gasification process using the GO methodology, and analyzes the system reliability. This article expands the scope of the GO methodology, and provides technical support for reliability analysis using the GO methodology in multi-fault systems.
