Description

In the risk assessment of multi-unit nuclear power plants (NPPs) in a single site, the realistic dose distribution calculation is a significant issue. So far, probabilistic safety assessment (PSA) analysts have been using the single location method that integrates all NPPs into one virtual NPP and the dose distribution calculation is once performed for the virtual NPP. This may result in quite different dose distribution from the reality. They are center-of-mass (COM) dose calculation method and multiple-location (ML) dose calculation method. In order to investigate the uncertainty of dose calculation methods for multi-unit NPPs in a site, the two dose distribution calculation methods of COM and ML methods are compared in this study. This study is summarized as ML method is recommended for equivalent dose calculation for general population distribution cases. COM method drastically overestimated or underestimated for general population distribution cases. COM method may result in quite different dose distribution from the reality.
