Licensing on exploration of nuclear ore in Indonesia

Exploration of Nuclear Ore in Indonesia is the beginning project from the nuclear ore cycle activity and it has been taken a priority to find uranium sources. Categorization of a district for looking uranium as well as inventarization nuclear ore is divided into three categorizations i.e. the Potential sources district (PSD), Indicated Speculative Source District (ISSD) and Speculative Source District (SSD). The licensing process has been done by BATAN (National Nuclear Energy Agency) both to Ministry of Energy and Mineral Resources and also to Nuclear Regulator Energy Agency (BAPETEN). According to geographical position and the purpose condition, the west of Indonesian Archipelago is known as contents amount uranium. Kalan district in West Kalimantan is one of the districts in Indonesia that has potential uranium sources. This area is facility assessed by Center for Development Nuclear Ore. (P2BGGN). The Kalan district covers 20 square meter and it is divided into two (2) sections, section I and section II. Both of them is included in the Pinoh Formation and characterized by the mineralization system dominated with Muscovite - quartz schist (rock), halite, slate, hornfels, some metatuff and quartzite. Andalusite, cordierite and biotite take in their own places; sillimanite and garnet are rarely found. The detailed examination has been done by making exploration tunnel that cut mineral's liner. This tunnel is also used to technical assessment of mining and ground floor drilling patterned based on differential mineralization spreading with point of view thickness geometrical and intensity (geological control and selected mining). There are two types of exploration tunnel, perforate tunnel and cross tunnel, that reach out for totally 760 meters long. (author)
