OVERVIEW OF INTERNATIONAL EXPERIENCE AND TESTS FOCUSED ON CEMENT-BASED MATERIALS PROPOSED TO PROVIDE THE LONG TERM SAFETY OF RADIOACTIVE WASTE REPOSITORIES

In-depth analysis of proposed materials should always precede the construction of purpose designed facilities. These studies primarily demonstrating their feasibility, performance, service life, when applied in aggressive environments, are basically seeking to validate the timeframes of their safe operation. This article analyses the studies that have been implemented at the Canadian Nuclear Research Center (Chalk River Laboratories), at a radioactive waste storage facility at the Dukovany NPP site in the Czech Republic, at the El Cabril radioactive waste storage facility (E1 Carbil facility) in Spain, as well as the results obtained within the framework of the international CRP project.

Keywords: radioactive waste management, radioactive waste, near-surface radioactive waste disposal facilities, radioactive waste disposal, concrete, cement-containing materials, degradation of materials.
