  • Implementing Geological Disposal of Radioactive Waste Technology Platform


Cebama is a research and innovation action granted by the European Atomic Energy Community in support of the implementation of the first-of-the-kind geological repositories. The 4-year project Cebama started 1st of June 2015 and is carried out by a consortium of 27 partners consisting of large Research Institutions, Universities, one TSO (Technical and Scientific Support Organizations), and one SME (small medium enterprise) from 9 EURATOM Signatory States, Switzerland and Japan. National Waste Management Organizations support Cebama by co-developing the work plan, participating in the End-User Group, granting co-funding to some beneficiaries, and providing for knowledge and information transfer.

The kick-off meeting of Cebama was held on Thursday, 2nd of July, 2015 in Brussels with selected representatives from all project beneficiaries joining. Cebama addresses key issues of relevance for long-term safety and key scientific questions related to the use of cement-based materials in nuclear waste disposal applications. The overall strategic objective of Cebama is to support the implementation of geological disposal by significantly improving the knowledge base for the Safety Case for European repository concepts. The scientific/technical research of Cebama is largely independent of specific disposal concepts and addresses different types of host rocks, as well as bentonite. Cebama is not focusing on one specific cementitious material, but aims at studying a variety of important cement-based materials in order to provide insight on general processes and phenomena which can then be easily transferred to different applications and projects. Specific objectives of Cebama are summarized are:

  • Perform experimental studies to understand the interface processes between cement-based materials and the host rocks (crystalline rock, Boom Clay, Opalinus Clay (OPA), Callovo-Oxfordian (COX)) or bentonite backfill and assess the impact on physical (transport) properties. (WP1).
  • Study radionuclide retention processes in high pH concrete environments. Radionuclides which have high priority from the scientific and applied perspective are selected. (WP2).
  • Improve validity of numerical models to predict changes in transport processes as a result of chemical degradation. Support advanced data interpretation and process modelling, covering mainly issues responsible for the changes in transport properties. (WP3)

A key activity of Cebama, open to all interested to participate, are the Annual Project Workshops which serve as an important forum for dissemination of the research performed within the project. The First Annual Project Workshop will be organized by Amphos21, over at least 2 days in the week from May 8th 2016, in Barcelona, Spain. Exact dates and registration will be available in 2016 at Cebama website. Cebama is offering the opportunity of external groups to join the project within the status of Associated Groups (AG). AGs can participate in Cebama at their own costs with specific scientific/technical contributions or particular information exchange functions. The AGs will be invited to the Annual Project Workshops and receive access to the public deliverables and scientific technical information obtained in the project (contact: This email address is being protected from spambots.
