Behaviour of Cementitious Materials in Long Term Storage and Disposal of Radioactive Waste (T21025)
The objective of the IAEA CRP was to investigate cementitious materials used in radioactive waste management systems. These included waste packages, wasteforms and backfills as well as investigation of interactions and interdependencies of these individual elements during long term storage and disposal
The CRP has involved 24 research organizations from 21 Member States that have shared research and practices on the use of cementitious materials. Research coordination meetings were held in the Russian Federation (Moscow, September 2007), Romania (Bucharest and Cheile Gradishtei, November 2008) and India (Kalpakam, October 2010).
The CRP results can be most effectively used as a screening tool to identify cementitious systems and technologies to meet specific waste management objectives in terms of the waste streams complexity, the available economic resources, the environmental impact considerations, and the desired end product (waste form) properties.
The execution of the CRP promoted the exchange of advanced information on the on-going research and development activities and facilitated access to the practical results of their application for conditioning of specific types of wastes. As a result of the CRP implementation a new knowledge and practical experience is established to improve their radioactive waste management practices.
