Hot-isostatically pressed wasteforms for Magnox sludge immobilisation
Autor: M. W. A. Stewart, Paul G. Heath, Neil C. Hyatt, S. Moricca
Publikováno v: Journal of Nuclear Materials. 499:233-241
Thermal treatment technologies offer many potential benefits for the treatment of radioactive wastes including the passivation of reactive species and significant waste volume reductions. This paper presents a study investigating the production of wa

Autor: S. Moricca, Eric R. Vance, M. W. A. Stewart, Daniel R.M. Brew, Catherine K.W. Cheung, Tina Eddowes, Walter Guillermo Bermudez
Publikováno v: Science and Technology of Nuclear Installations, Vol 2013 (2013)
A variety of intermediate- and low-level liquid and solid wastes are produced from reactor production of99Mo using UAl alloy or UO2targets and in principle can be collectively or individually converted into waste forms. At ANSTO, we have legacy acidi

Zirconolite-rich titanate ceramics for immobilisation of actinides – Waste form/HIP can interactions and chemical durability
Autor: S. Moricca, Eric R. Vance, Huijun Li, Yingjie Zhang, Melody L. Carter, M. W. A. Stewart
Publikováno v: Journal of Nuclear Materials. 395:69-74
Zirconolite-based titanate ceramics containing U plus Th or Pu have been prepared. The final consolidation to produce a dense monolithic waste form was carried out using hot isostatic pressing (HIPing) of the calcined materials within a stainless ste

Progress at ANSTO on a Synroc Plant for Intermediate-Level Waste from Reactor Production of 99Mo
Autor: Eric R. Vance, S. Moricca, M. W. A. Stewart
Publikováno v: Advances in Science and Technology.
Intermediate level waste from ANSTO’s expanded 99Mo production plant will consist of ~5000L/year of 6M NaOH + 1.4 NaAlO2 + fission products. Detailed engineering is being carried out on a synroc plant to immobilise this waste in a glass-ceramic, wi

Publikováno v: Volume 1: Low/Intermediate-Level Radioactive Waste Management; Spent Fuel, Fissile Material, Transuranic and High-Level Radioactive Waste Management.
NNL and ANSTO on behalf of Sellafield Ltd have developed a process for the immobilisation of a range of Pu containing wastes and residues. Following the inactive demonstration of the technology the project is now focusing on the design of an active p

Advanced Ceramics and Glass-Ceramics for Immobilisation of ILW and HLW
Autor: Eric R. Vance, M. W. A. Stewart, S. Moricca
Publikováno v: MRS Proceedings. 1475
Since the 1970s there has been a steady increase in research on candidate ceramic and glass-ceramics for immobilisation of HLW and ILW, both from the aspects of crystal-chemical design and processing technology. The variety of ceramics and glass-cera

Freudenbergite: A Possible Synroc Phase for Sodium-Bearing High-level Waste
Autor: M. W. A. Stewart, Mark G. Blackford, Eric R. Vance, Paul J. Angel, David J. Cassidy, Peter A. McGlinn
Publikováno v: Journal of the American Ceramic Society. 77:1576-1580
Earlier studies have shown that the presence of excess sodium in high-level nuclear waste can give rise to increased leachability when the waste is incorporated in Synroc-type titanate ceramics. Freudenbergite (Na2Al2Ti6O16) can incorporate sodium an
