Abstract The U-Pu-Zr metallic fuels contain multiple phases whose properties and
distributions evolve due to factors such as fission, nuclear transmutation, and elemental …

Abstract A uranium-22.5 atomic% zirconium (U-22.5 at.% Zr) alloy was characterized using
transmission electron microscopy (TEM) following hot/cold-rolling, and again following a …

Ternary alloys consisting primarily of uranium, plutonium, and zirconium (U-Pu-Zr) are
among the leading candidate fuel systems considered for fast spectrum nuclear reactors …

Palladium is being investigated as a potential additive to metallic fuel to bind fission product
lanthanides, with the goal of reducing or preventing fuel-cladding chemical interactions …

This article reports the results of the microstructural examination of the irradiated U–19Pu–
10Zr fuel. New insights gained using selective area electron diffraction analysis in a …

lanthanides, with the goal of reducing or preventing fuel-cladding chemical interactions …

Minor actinide transmutation fuels, of which U-Pu-Zr is one of the most promising, have been
the subject of renewed interest for fast reactor applications. Unfortunately, we lack the …

Exposure to high temperatures and irradiation results in interaction and interdiffusion
between fuel and cladding constituents that can lead to formation of undesirable brittle or …

Phase diagrams constructed for the Pu-Zr binary system report the existence of θ-(Pu, Zr), δ-
(Pu, Zr), γ-Pu, α-Pu, β-Pu, and ζ-Pu 28 Zr phases in Pu-enriched region, when Pu …

U-Pu-Zr alloys are considered ideal metallic fuels for experimental breeder reactors
