From strategy to plan - new revision of decommissioning and waste disposal programfor NPP Kr?ko

摘要

According to the requirements of the bilateral agreement between Republic of Slovenia andRepublic of Croatia on the legal and other obligations for Nuclear power plant (NPP) Kr?ko which is sharedbetween both republics the Program of NPP Kr?ko Decommissioning and SF and LILW Disposal (the Program)was prepared in 2004. The main purpose of the Program was to estimate the overall expenses of the futuredecommissioning, radioactive waste and spent fuel management of the NPP Kr?ko in order to establish separatefund in Croatia and to correct the rate per kWh collected in the existing decommissioning fund in Slovenia. Theprogram looked at all possible scenarios of dismantling, radioactive waste and spent fuel management andproposed the most plausible two scenarios which are technically possible and financially feasible. The Programincludes also the recommendations for the further work on the Program while the next revision of the Programshould be prepared in 5 years time,in 2009. To make good progress in the next revision serious preparationsincluding some strategic decisions have started immediately. While the Program from 2004 was prepared undertime pressure many important aspects of decommissioning and waste disposal were not sufficiently elaborated,some others were omitted from further investigation because of imposed boundary conditions. In 2005 ARAOand APO also joined the IAEA regional project on "Support to decommissioning of NPP's" under which IAEAexpert mission of the Program was performed. According to the IAEA expert mission recommendations firstPreliminary Decommissioning Plan (PDP) will have to be drawn up including a detailed cost estimation basedon pre-decommissioning characterization. In parallel other missing documents specifically on LILW and SFmanagement will be prepared according to the development of the projects. Finally the incorporation of thefindings of all different modules will be combined in the new revision of the Program. The paper will present thesolutions of the first 2004 revision and will describe the plans for preparation of the new revision of the Programin 2009.
