For the interim storage of spent nuclear fuel (SNF), a dry storage-transportation technology in cast iron and metal-concrete casks is implemented at the Ignalina NPP. At the moment, 80 GNB (Germany) casks are stored at an open type facility. A new project of a storage facility for the remaining SNF has been started recently. Higher capacity metal concrete containers (about 200 units) of the same company will be stored in a closed type (special building) facility. In 2003, The Programme of Assessment of Possibilities of the Disposal of Spent Nuclear Fuel and Long-lived Radioactive Waste for the years 2003-2007 was prepared and approved. Geological and hydrogeological investigations performed in the frame of this program revealed that crystalline rocks and clayey geological formations are most promising for the geological disposal of SNF in Lithuania. The preliminary concept of the repository was developed, and preliminary investigations on nuclide migration, heat removal, criticality and radiation fields have been performed.
