摘要：

Fast-reactor fuel alloys produce lanthanide fission products which migrate to the fuel/cladding interface causing fuel-cladding chemical interaction. To test viability of pinning these lanthanides, neodymium was selected as an iron interacting lanthanide and palladium was chosen as the dopant. An arc-melt produced 1:1 neodymium-palladium compound and pure neodymium were tested against iron in diffusion couples at temperatures above and below the Nd-Fe eutectic melting point.
