An external event identification for Nuclear Power Plant (NPP) siting project at West Kalimantan, Indonesia

The research aims to determine the existing external event for Nuclear Power Plant (NPP) Siting project at West Kalimantan. The identification of external hazard potential studies is carried out based on the IAEA safety guide and BAPETEN regulations regarding external potential hazards which include seismic aspects, surface faults, extreme meteorology, geotechnics, volcanoes which must be carried out in determining the NPP’s site. The method used in this research is field ground check and desk work analysis with references related to identified external hazards. The results showed that the potential site of the NPP’s in West Kalimantan Province is safe from potential external natural hazards. The NPP’s site has also been determined to be safe from the dangers of flooding due to tsunamis and flood overflows, no capable faults are found, and far from potential volcanic hazards. Extreme meteorological potential is rare at site sites. To evaluate the oceanography aspect, the existence of physical oceanographic conditions must be carried out in-depth studies in the future, especially related to the sedimentation process that has occurred around the nuclear power plant site.
