Preliminary spatial analysis for NPP site selection on West Kalimantan

The need for electrical energy in Indonesia is still high, especially in areas directly adjacent to other countries such as West Kalimantan Province. To fulfill the demand, some electricity should be imported from neighboring countries each year. In addition, the projected growth of industries that require electrical energy such as aluminum, oil palm, rubber and the development of the Kijing port will largely increase electricity demand. Thus the Government took the initiative to increase the number of power plant in the framework of the fulfillment of electricity demand in West Kalimantan Province . The purpose of this study was to identify areas that have the potential to become safe and suitable sites for nuclear power plants in the province of West Kalimantan. The method used was raster analysis using ArcGIS software from spatial data on external events that can affect site safety. Input aspects are spatial data from geological structure, lithology, special forest, peat land, and land use. The results shows that the province of West Kalimantan has medium to high potential to be used as potential sites for nuclear power plants. They are located in Bengkayang regency, Ketapang regency and Singkawang city. (author)
