TBC, 2009, Committee on Radioactive Waste Management: REPORT TO GOVERNMENT, INTERIM STORAGE OF HIGHER ACTIVITY WASTES AND THE MANAGEMENT OF SPENT FUELS, PLUTONIUM AND URANIUM, UK, CoRWM Document 2500

This is one of three CoRWM reports to Government in 2009. The reports are about: interim storage of higher activity wastes (including waste conditioning, packaging and transport, and the management of materials that may be declared to be wastes) (this report) the implementation of geological disposal of higher activity wastes research and development for interim storage and geological disposal.The reports cover the three strands of the Government’s Managing Radioactive Waste Safely programme. They contain the results of CoRWM’s scrutiny, during 2008 and the first part of 2009, of the work of the Government, the Nuclear Decommissioning Authority, other nuclear industry organisations, the regulators, local authorities and various organisations that carry out research. The recommendations in the reports are to Government but also affect others.

Pontikes Y, Rathossi C, Nikolopoulos P, Angelopoulos GN, Javaseelan DD, Lee WEet al., 2009, Effect of firing temperature and atmosphere on sintering of ceramics made from Bayer process bauxite residue, Ceramics International, Vol: 35, Pages: 401-407, ISSN: 0272-8842

Bauxite residue, the principal waste from the Bayer process, was dried, pressed and studied for its thermal and sintering behaviour under different atmospheres, up to 1100 degrees C. For sintering in air and N-2, shrinkage begins at 800 degrees C and ranges from 2.6% to 13.9%, after firing at 1000-1100 degrees C. Bulk density varies from 1.7 to 2.3 g/cm(3) whereas water absorption from 31.5% to 17.7%. The main crystalline phases identified on firing in air were hematite (Fe2O3), gehlenite (Ca2Al2SiO7) and perovskite (CaTiO3) whereas magnetite (Fe3O4) was also found on firing in N-2. Microstructures are characterised by irregularly shaped, <20 mu m Feret diameter, pores in a ceramic matrix with interconnected porosity. The average pore size is greater in samples fired in N-2. On sintering in 4%H-2/Ar, shrinkage begins at 710 degrees C. After firing at 1100 degrees C, shrinkage is 20.1% and water absorption 1%. The main crystalline phases are magnetite, wustite (FeO), gehlenite and perovskite. Mcrostructures are characterised by a compact heterogeneous matrix, with isolated <15 mu m. Feret diameter, closed pores. The grains have reacted with the adjacent phase and their shape is rounded with no sharp facets. Increased sintering temperature results in improved physical properties for all atmospheres tested and in higher average pore size when sintering takes place in air and N-2. The use of magnetite-reducing sintering conditions can potentially assist in the production of a variety of ceramic compositions containing bauxite residue. (C) 2008 Elsevier Ltd and Techna Group.

Tarvornpanich T, Souza GP, Lee WE, 2008, Microstructural evolution in clay-based ceramics II: Ternary and quaternary mixtures of clay, flux, and quartz filler, Journal of the American Ceramic Society, Vol: 91, Pages: 2272-2280, ISSN: 0002-7820

The complex microstructural evolution in mixtures of kaolinite clay, quartz, nepheline syenite, and soda-lime-silica (SLS) glass has been revisited. Detailed descriptions of reactions leading to dense whiteware bodies backed by semi-quantitative X-ray diffraction analysis reveal that ternary mixtures containing nepheline syenite differ from those containing SLS glass, as new crystalline phases develop inside and at the interfaces among SLS glass particles and decomposed clay and quartz. In SLS glass-fluxed mixtures, tridymite formation was hindered and cristobalite formed at ≥ 750°C followed by wollastonite at ≥ 8001C. Albite and plagioclase formed from interaction between clay and molten SLS glass above 800°C. Wollastonite was not present ≥ 1100°C, leaving only cristobalite in the surrounding regions. Quartz partially dissolves at temperatures ≥ 10001C after interacting with molten SLS glass. In quaternary mixtures containing 6.25 wt% SLS glass and 17.25 wt% nepheline syenite fluxes, formation of types II and III secondary mullite was more pronounced than in the fully SLS glass-fluxed mixture. The more fluid liquid from nepheline syenite enhances the growth kinetics of mullite. The body fired at the optimum firing temperature (1100°C) has a microstructure containing primary type I and secondary types II and III mullites, remnant cristobalite, plagioclase, and partially dissolved quartz embedded in the glassy phase. Providing a roadmap for microstructural design in clay-based systems may have significant commercial impact in the emerging technology of use of waste materials in clay-based ceramics. © 2008 The American Ceramic Society.

Glass composite materials (GCM) are versatile wasteforms for immobilising various typesof both radioactive and hazardous wastes. We review current research on the utilisation of GCMsfor hazardous and radioactive waste immobilisation. Compared to homogeneous glassy materialsGCMs can incorporate larger amounts of waste elements and, in the case of glass matrixcomposites, they can be produced using lower processing temperatures (by viscous flowsintering) than those of conventional melting.
