The development of new concrete mixtures as part of the ICONDE project aims to offer new solutions for radioactive waste management. The long-term lack of hazardous waste storage solutions and technologies is a problem for the entire Baltic region. An example of a source of large-scale radioactive waste of all stages is the decommissioning of the Ignalina Nuclear Power Plant (NPP). It will propose a new pathway for the utilization of existing industrial waste - the oil shale ash. This supports the UN's sustainable development goals for circular material flow. Advancement of the mechanical properties is expected to be achieved by the addition of fibers. Specific interest from the viewpoint of spent nuclear fuel storage solutions is the use of basalt-boron fibers in the concrete mixture to improve shielding against neutrons.
