TL;DR: In this article, a cross-sectional examination of NiZr bilayers annealed at 300°C has shown the formation of amorphous NiZrs and the development of large voids in the nickel neighboring the Ni/NiZr interface.
Abstract: The interdiffusion of nickel and zirconium by a solid‐state reaction to form an amorphous NiZr alloy has been followed by transmission electron microscopy. Cross‐sectional examination of NiZr bilayers annealed at 300 °C has shown the formation of amorphous NiZr and the development of large voids in the nickel neighboring the Ni/NiZr interface. Our results indicate that nickel is the dominant diffusing species in the amorphous alloy and that the diffusion requires a defect mechanism. Prolonged annealing at 300 °C results in the formation of a crystalline NiZr phase, which co‐exists with the amorphous alloy.

TL;DR: In this paper, the neutronic performance of accident tolerant fuels (ATF) was analyzed in both pressurized and boiling water reactors, and two concepts were evaluated: (1) coating the exterior of zirconium-alloy cladding with thin ceramics to limit the zirconsium available for reaction with higher temperature steam; (2) replacing ZIRconium alloys with alternative materials possessing slower oxidation kinetics and reduced hydrogen production.
