PEMILIHAN TAPAK POTENSIAL UNTUK DISPOSAL LIMBAH RADIOAKTIF OPERASI PLTN DI BANGKA SELATAN

POTENTIAL SITE SELECTION OF DISPOSAL FOR RADIOACTIVE WASTE GENERATED FROM NPP OPERATION IN SOUTH BANGKA. As mentioned on Act No. 10/1997 and Government Regulation No. 61/2013 that radioactive waste must be managed until the disposal as well as to avoid the hazard to the public and environment. In the National Research Agenda Year 2010-2014 especially on the sub theme of Nuclear Energy was mentioned that determination of disposal sites should be inisiated. The statement about radioactive waste disposal program also mentioned clearly on BATAN Strategic Plan and PTLR Strategic Plan Year 2010-2014. Based on the basic laws mentioned above, in supporting the acceleration of nuclear power plants (NPP) development and operation in the Bangka Islands, the study of disposal site candidate for radioactive waste arising from operation of NPP in Bangka have been done. In the year 2013, selection of potential sites have been conducted. IAEA Safety Series No. 111-G-3.1 have been adopted as a study approach, which recommends the steps of radioactive waste disposal site selection to 4 steps: 1) Conceptual and Planning Stage, 2) Survey Area Stage, 3) Site Characterization Stage, and 4) Site Confirmation Stage. Aspects of the study were considered in the selection of potential sites include topography, hydrology, geology, mineral resources, and land use / spatial planning. The method used in the selection of potential sites is buffering, scoring and overlay techniques. For disposal concepts that can be applied (near surface disposal and deep geological disposal) in igneous rocks such as granite, granodiorite and adamelite, the potential sites for disposal can be selected on a land relatively close to the nuclear power plant site candidates in South Bangka.
