The BSK 3 container concept is intended for the direct borehole disposal of SNF in salt rock. The container can accommodate the fuel rods from three PWR or nine BWR fuel assemblies. The container is unshielded and has a maximum diameter of approximately 440 mm. The diameter of the BSK 3 container was selected so that the SNF could be disposed of in the same type of borehole that is planned for the disposal of HLW casks. A variation BSK 3 concept referred to as the ‘Triple-Pack’ was developed by DBE Technology GmbH to contain three HLW casks with a diameter of 430 mm. Using the Triple-Pack and BSK 3 concepts for borehole disposal would optimize the use of handling and emplacement equipment requirements.
