An innovative design for low and intermediate radwaste near surface repository in Lithuania - 59382

Document available in abstract form only. Full text of publication follows: In 2009, in response to an open tender, funded by the European Bank for Reconstruction and Development, a consortium comprising Lithuanian and French partners led by Areva was selected by Ignalina nuclear power plant (INPP) to design a dedicated 100.000 m3 LILW-SL Near Surface Repository (NSR) planned to be constructed nearby the power plant. After preliminary siting studies, the site of Stabatiske was selected by the Lithuanian government in 2007. Following this decision, the projects technical and commercial requirements for the NSR design was prepared by experts from INPP with the support of the Lithuanian radwaste management agency (RATA). This NSR is to be developed and engineered for the disposal of INPP radwaste produced by its operation, and arising from its dismantling. The result of the project is to develop, following IAEA guidelines, an innovative multi-barrier repository design which is engineered for the Stabatiske site, with the presence of groundwater, for the sites characteristics, comprising clay layers, moraine deposits and aquifers, and for the volume and type of radwaste, the disposal containers and the engineered barriers. This design is on schedule for completion in 2013, and will provide the basis for the construction of the repository
