Abstract

We report synchrotron scattering analysis results on U-7wt%Mo fuel samples irradiated in the Advanced Test Reactor to three different burnup levels. Mature fission gas bubble superlattice was observed to form at intermediate burnup. The superlattice constant was determined to be 11.7 nm and 12.1 nm by wide-angle and small-angle scattering respectively. Grain sub-division takes place throughout the irradiation and causes the collapse of the superlattice at high burnup. The bubble superlattice expands the lattice constant and acts as strong sinks of radiation induced defects. The evolution of dislocation loops was therefore suppressed until the bubble superlattice collapses.

High-energy synchrotron study of in-pile-irradiated U–Mo fuels

Journal Article Miao, Yinbin ; Mo, Kun ; Ye, Bei ; ... - Scripta Materialia

Here synchrotron scattering analysis results on U–7wt.%Mo fuel specimens irradiated in the Advanced Test Reactor to three burnup levels (3.0, 5.2, and 6.3 × 1021 fission/cm3) are reported. Mature fission gas bubble superlattice was observed to form at intermediate burnup. The superlattice constant was determined to be 11.7 and 12.0 nm by wide-angle and small-angle scattering respectively. Grain sub-division takes place throughout the irradiation and causes the collapse of the superlattice at high burnup. The bubble superlattice expands the U–Mo lattice and acts as strong sink for radiation-induced defects. The evolution of dislocation loops was, therefore, suppressed until the bubblemore » superlattice collapsed.« less

Transmission electron microscopy characterization of the fission gas bubble superlattice in irradiated U-7wt% Mo dispersion fuels

Journal Article Miller, B. D. ; Gan, J. ; Keiser, D. D. ; ... - Journal of Nuclear Materials

Transmission electron microscopy characterization of irradiated U-7wt% Mo dispersion fuel was performed on various samples to understand the effect of irradiation parameters (fission density, fission rate, and temperature) on the self-organized fission-gas-bubble superlattice that forms in the irradiated U-Mo fuel. The bubble superlattice was seen to form a face-centered cubic structure coherent with the host U-7wt% Mo body centered cubic structure. At a fission density between 3.0 and 4.5 x 10²¹ fiss/cm³, the superlattice bubbles appear to have reached a saturation size with additional fission gas associated with increasing burnup predominately accumulating along grain boundaries. At a fission density ofmore »« less

Contributions to the mechanistic understanding of the microstructural evolution in irradiated U-Mo dispersion fuel

Journal Article Salvato, Daniele ; Smith, Charlyne A. ; Pavlov, Tsvetoslav R. ; ... - Journal of Nuclear Materials

Here, advanced microstructural characterization techniques, such as scanning electron microscopy (SEM) and scanning transmission electron microscopy - energy dispersive x-ray spectroscopy (STEM-EDS), were used to interpret the fuel microstructure evolution and fission products behavior in U-Mo dispersion fuel irradiated in the Advanced Test Reactor (ATR) as part of the European Mini-Plate Irradiation Experiment (EMPIrE) test. The larger as-fabricated fuel grain size achieved by heat-treating the U-Mo powder resulted in slower high burnup structure (HBS) development and reduced fission gas porosity. Slower HBS kinetics was observed at the fuel kernels’ periphery, which contained smaller and less fission gas bubbles at allmore »« less

Transmission electron microscopy investigation of irradiated U-7 wt% Mo dispersion fuel

Conference Berghe, S van den ; Renterghem, W van ; Leenaers, A

The microstructural evolution of atomised U-7wt%Mo alloy fuel under irradiation was investigated with transmission electron microscopy on material from the experimental fuel plates used in the FUTURE irradiation. The unsatisfactory irradiation behaviour of this atomised U(Mo) alloy dispersion fuel during this experiment was derived to be related to the properties of the interaction layer formed between the U(Mo) particles and the Al matrix. It is assumed to become amorphous under irradiation and as such cannot retain the fission gas in stable bubbles. As a consequence, gas filled voids are generated between the interaction layer and the matrix, causing the fuelmore »« less
Formation of tetragonal gas bubble superlattice in bulk molybdenum under helium ion implantation

Journal Article Sun, Cheng ; Sprouster, David J. ; Hattar, K. ; ... - Scripta Materialia

In this paper, we report the formation of tetragonal gas bubble superlattice in bulk molybdenum under helium ion implantation at 573 K. The transmission electron microscopy study shows that the helium bubble lattice constant measured from the in-plane d-spacing is ~4.5 nm, while it is ~3.9 nm from the out-of-plane measurement. The results of synchrotron-based small-angle x-ray scattering agree well with the transmission electron microscopy results in terms of the measurement of bubble lattice constant and bubble size. The coupling of transmission electron microscopy and synchrotron high-energy X-ray scattering provides an effective approach to study defect superlattices in irradiated materials.
