Abstract

The Mo₂Zr phase has been identified as a major interaction product at the interface of U-10Mo and Zr. Transmission electron microscopy in-situ irradiation with Kr ions at 200 °C with doses up to 2.0E+16 ions/cm² was carried out to investigate the radiation stability of the Mo₂Zr. The Mo₂Zr undergoes a radiation-induced structural change, from a large cubic (cF24) to a small cubic (cI2), along with an estimated 11.2% volume contraction without changing its composition. The structural change begins at irradiation dose below 1.0E+14 ions/cm². Furthermore, the transformed Mo₂Zr phase demonstrates exceptional radiation tolerance with the development of dislocations without bubble formation.

Stability Study of the RERTR Fuel Microstructure

Conference Gan, Jian ; Keiser, Dennis ; Miller, Brandon ; ...

The irradiation stability of the interaction phases at the interface of fuel and Al alloy matrix as well as the stability of the fission gas bubble superlattice is believed to be very important to the U-Mo fuel performance. In this paper the recent result from TEM characterization of Kr ion irradiated U-10Mo-5Zr alloy will be discussed. The focus will be on the phase stability of Mo2-Zr, a dominated second phase developed at the interface of U-10Mo and the Zr barrier in a monolithic fuel plate from fuel fabrication. The Kr ion irradiations were conducted at a temperature of 200 degreesmore »« less

Ion-beam-induced phase transformations in {delta}-Sc{sub 4}Zr{sub 3}O{sub 12}

Journal Article Ishimaru, Manabu ; Hirotsu, Yoshihiko ; Tang, Ming ; ... - Journal of Applied Physics

Structural changes in ion-beam-irradiated rhombohedral Sc{sub 4}Zr{sub 3}O{sub 12} ({delta}-Sc{sub 4}Zr{sub 3}O{sub 12}) have been examined using transmission electron microscopy (TEM). Polycrystalline {delta}-Sc{sub 4}Zr{sub 3}O{sub 12} samples were irradiated at cryogenic temperature with 300 keV Kr{sup 2+} ions to a fluence of 3x10{sup 16} Kr/cm{sup 2} (equivalent to a peak dose of {approx}70 displacements per target atom). High-resolution TEM and nanobeam electron diffraction experiments revealed a phase transformation to another ordered crystalline phase in the near-surface region of the irradiated sample. We propose an atomistic model for this crystalline phase, based on the bixbyite structure, and discuss its formation process.more »« less

Investigation of Interdiffusion Behavior in the Mo-Zr Binary System via Diffusion Couple Studies

Journal Article A. Paz y Puente ; Dickson, J. ; D.D. Keiser, Jr. ; ... - International Journal of Refractory Metals and Hard Materials

Zirconium has recently garnered attention for use as a diffusion barrier between U–Mo metallic nuclear fuels and Al alloy cladding. In order to gain a fundamental understanding of the diffusional interactions, the interdiffusion behavior in the binary Mo–Zr system was investigated via solid-to-solid diffusion couples annealed in the temperature range of 750 to 1050 degrees C. A combination of scanning electron microscopy, X-ray energy dispersive spectroscopy, and electron probe microanalysis were used to examine the microstructure and concentration profiles across the interdiffusion zone. A large __-Zr (cI2) solid solution layer and a thin (approximately 1–2 um) layer of Mo2Zr (cF24)more »« less

Chemical and radiation stability of a proprietary cesium ion exchange material manufactured from WWL membrane and SuperLig{reg_sign} 644

Technical Report Brown, G N ; Carson, K J ; DesChane, J R ; ...

Pretreatment of nuclear process wastes for ion exchange removal of Cs and other radionuclides is one way to minimize amount of high-level radioactive waste at Hanford. This study evaluated Cs-selective SuperLig{reg_sign}644 (IBC Advanced Technologies, American Fork UT) entrapped in a proprietary WWL web membrane (3M) for chemical/radiation stability in simulated caustic neutralized current acid waste (NCAW), 0.5M HNO{sub 3}, water, and air. After exposure up to 2.0E+09 rad, the material was evaluated for Cs uptake in 5M sodium NCAW simulants with varying Cs contents. Radiolytic stability appears to be sufficient for ion exchange pretreatment of radioactive Cs: essentially no decreasemore »« less

Near-Edge X-ray Absorption Fine-Structure Study of Ion-Beam-Induced Phase Transformation in Gd{sub 2}(Tl{sub 1-y}Zr{sub y}){sub 2}O{sub 7}

Journal Article Nachimuthu, Ponnusamy ; Thevuthasan, Suntharampillai ; Shutthanandan, V ; ... - Journal of Applied Physics

The structural and electronic properties of Gd{sub 2}(Tl{sub 1-y}Zr{sub y}){sub 2}O{sub 7} (y = 0-1) pyrochlores following 2.0 MeV Au{sup 2+} ion-beam irradiation ({approx}5.0 x 10{sup 14} Au{sup 2+}/cm{sup 2}) have been investigated by Ti 2p and O 1s near-edge x-ray absorption fine structure (NEXAFS). The irradiation of Gd{sub 2}(Tl{sub 1-y}Zr{sub y}){sub 2}O{sub 7} leads to the phase transformation from the ordered pyrochlore structure (Fd3m) to the defect fluorite structure (Fm3m) regardless of Zr concentration. Irradiated Gd{sub 2}(Tl{sub 1-y}Zr{sub y}){sub 2}O{sub 7} with y {le} 0.5 are amorphous although significant short-range order is present. Contrasting to this behavior, compositions withmore »« less
