“…different prediction reliability durations are needed, ranging from a few decades for civil engineering structures to a thousand years for the nuclear waste package containers foreseen for repositories in several countries (France, Belgium, Japan, Switzerland,…). 16 Analogues can thus be used in several ways. They may, for example, serve to validate if the corrosion kinetics deduced from short-term experiments and extrapolated to the long term are consistent with the corrosion thicknesses found on archaeological objects.…”

Abstract-One of the major worldwide environmental issue is the long-term storage or disposal of nuclear waste. Research in solidification materials for long-term storage of high-level nuclear wastes in nuclear industry has started as an imperative need. During the last decade, new solidification materials have been developed for immobilization of actinides and fission products for geological disposal. The materials used for immobilization generally have relatively complex compositions. The structure of these materials investigates using diffraction and spectroscopic methods. Most of the interest has focused on their chemical durabilities and capacity of waste loading. Their physical and chemical properties should not be degraded by -decay event irradiation from the incorporated actinides. The development of new materials either for storage or for disposal for a long time is still required. In this article, recent developments in the use of solidification materials for the immobilization of high level of nuclear wastes have been reviewed. The comparison of properties of solidification materials is summarized with several applications in connection with experience and technological needs in literature.

Microstructure and Mechanical Properties of Zr‐4 Alloy and 316 Stainless Steel Diffusion Bonding Joint Using Nb/Ni Composite Interlayer

et al. 2023

Diffusion bonding of Zr‐4 alloy and 316 stainless steel (SS) without and with the Nb/Ni composite interlayer has been performed. The maximum shear strength of the joint without interlayer is 131 MPa at 900 °C for 30 min under 10 MPa. The results show that the fracture occurs at the diffusion layer as a result of the limited mutual solubility between Zr and Fe and detrimental residual stress. Sound diffusion bonding joints without defects are obtained at lower bonding temperatures due to the addition of Nb/Ni interlayer, and the maximum shear strength is 380 MPa at 820 °C. The typical microstructure of the Zr‐4/Nb/Ni/316SS joint is Zr‐4/Zr(Nb)/Zr(Fe, Nb)2 /Zr(Nb)/Nb/Ni3Nb/Ni/(Fe, Cr, Ni)/316SS. The highest hardness value of the joint is 422 HV at the Ni3Nb phase, and cracks appear at the interface between Ni3Nb and the remaining Ni foil. The shear strength first increases and then drops as the Ni3Nb layer thickened. The peak residual stress of the joint reduces from 698 to 466 MPa due to the addition of the Nb/Ni composite interlayer. Finally, the growth kinetic model of the Ni3Nb layer is calculated, which provides a pathway for the regulation of joint properties.
