| Dependency Analysis of Human Failures in Multi-Unit Scenarios: Types and Evaluation Method |
|---|
| Abstract: Dependency between human failure events (HFEs) is often analyzed as a part of the conventional human reliability analysis (HRA) process for nuclear power plants (NPPs). Many regulators suggested that the probabilistic risk assessment (PRA) should be included in the dependency between HFEs. In this study, we aim to investigate characteristics based on the results, performing dependencies on about 800 combinations in a multi-unit cutset. From 2017 to 2021, we participated in a project to develop a multi-unit PSA model for regulatory use. It was developed for nine nuclear power plants at the Kori site in Korea. We performed HEP quantification and dependency required in the PSA model and provided the results. This was analyzed using the multi-unit HFE dependency evaluation method. We developed a set of multi-units HFE dependency evaluation elements and their evaluation criteria based on the framework of the single-unit evaluation elements that have been utilized in the HRA practice for NPPs. The result of this work will be used to modify the recently developed multi-unit HFE dependency analysis method for qualitative analysis. |
