DENKMAL, Phase 1

Optimization of direct disposal through canister emplacement in boreholes, feasibility study, and design and concept planning

The overall objective of the project is to develop and test a technically feasible concept for the disposal of spent fuel rods from intact fuel assemblies in vertical boreholes.

During Phase 1, a feasibility analysis will be conducted to determine the conditions under which the complete cycle of emplacing canisters loaded with intact fuel rods can take place. This includes examining transport above ground, shaft transportation, underground transport, and finally, emplacement in a vertical borehole. Based on this analysis, requirements for the emplacement components will be developed, necessary areas of investigation will be identified, and a technical concept will be derived. Phase 1 will conclude with a design plan for the selected concept.

The project is co-funded by the EU and is part of the Integrated Project IP ESDRED (Engineering Studies and Demonstration of Repository Designs) under the 6th EU Framework Programme (2002-2006). In Phase 2, the test components will be planned, manufactured, and prepared for the demonstration test along with existing components such as plateau wagons and emplacement locomotives. Specifically, the technical feasibility will be demonstrated, operational safety will be verified through a sufficient number of demonstration tests, and conclusions will be drawn for safety during the post-operational phase.
