| An Exploratory Study on Decision to Main Control Room Abandonment due to Fire-Induced Loss of Habitability: Using a VR Nuclear Power Plant Main Control Room Simulator |
|---|
| In Fire PRA/HRA on nuclear power plant, the criteria related to concentration of smoke or room temperature for main control room (MCR) abandonment due to loss of habitability (LOH) are given by NUREG-6850. However, the criteria are so severe for human body that it is unclear at what point operators will decide to abandon the MCR if a fire actually breaks out. Also, because MCR fire events are very rare and impossible to be simulated in real MCR, it would be difficult for operators themself to answer clearly about their own timing to decide to abandon during MCR fires. Using virtual reality (VR) technology to allow operators to experience MCR fires may make it easier to collect data about their timing of MCR abandonment. Therefore, this study aims to develop a virtual environment of an MCR fire using a VR nuclear power plant MCR simulator and collect data on decision-makings on MCR abandonment to improve fire HRA. Based on NUREG-1934, content with event of an electrical cabinet fire in MCR was developed by using the VR nuclear power plant MCR simulator. To make the content more realistic, an interview about responses to fire events in MCR, with checking the content, was conducted with the sift managers of an electric power company, and malfunctions to be simulated were determined. An experiment with operators as subjects will be conducted using the contents revised with reference to the interview. |
