Keywords:Containment Vent, STAMP/STPA, Fuzzy Inference

We identified the hazard causal factors using the qualitative risk analysis focusing on the interactions among organizations [1]. An integrated quantitative approach is proposed to analyze the judgement of the primary containment venting applying fuzzy inference.
