Cement-Based Materials for Nuclear Waste Storage [Paperback]

As the re-emergence of nuclear power as an acceptable energy source on an international basis continues, the need for safe and reliable ways to dispose of radioactive waste becomes ever more critical. The ultimate goal for designing a predisposal waste-management system depends on producing waste containers suitable for storage, transportation and permanent disposal. Cement-Based Materials for Nuclear-Waste Storage provides a roadmap for the use of cementation as an applied technique for the treatment of low- and intermediate-level radioactive wastes. Coverage includes, but is not limited to, a comparison of cementation with other solidification techniques, advantages of calcium-silicate cements over other materials and a discussion of the long-term suitability and safety of waste packages as well as cement barriers.This book analyzes cementation for treating low- and intermediate-level radioactive wastes, comparing it with other solidification methods, reviewing benefits of calcium-silicate cements, and assessing long-term safety of waste packages and cement barriers.Part I: Methods of Production of Cement-Waste Forms.- A Summary of IAEA-Coordinated Research Project on Cementitious Materials for Radioactive Waste Management.- R&D on Cementation of Pulp with Complex Physical and Chemical Composition Stored in Tanksat the Mining Chemical Combine.-?Cementation in High Energy Mixer of ILW Surrogate Slurry: Demonstration of the Process at Semi-Industrial Scale.- Part II: Physico-Chemical Processes Occurring in Cement-Waste Forms at Early Age.- Hydration of Blended Cements.- Application of a Sub-Lattice Model to Predictions of Cement Hydrate Chemistry.-Characterization and Solubility Determination of the Solid-Solution Between AFm-I2 and AFm-SO4.- Part III:Influence of External and Internal Factors on Long-Term Properties of Cement-Waste Package and Cement Barriers.- Coupling Between Leaching and Mechanical Behavior of Concrete.- Coupled MechanlCk
