Abstract

The microstructure modifications of a high-energy Xe implanted U₃Si₂, a promising accident tolerant fuel candidate, were characterized and are reported upon. The U₃Si₂ pellet was irradiated at Argonne Tandem Linac Accelerator System (ATLAS) by an 84 MeV Xe ion beam at 300 °C. The irradiated specimen was then investigated using a series of transmission electron microscopy (TEM) techniques. A dense distribution of bubbles were observed near the range of the 84 MeV Xe ions. Xe gas was also found to accumulate at multiple types of sinks, such as dislocations and grain boundaries. Bubbles aggregated at those sinks are slightly larger than intragranular bubbles in lattice. At 300 °C, the gaseous swelling strain is limited as all the bubbles are below 10 nm, implying the promising fission gas behavior of U₃Si₂ under normal operating conditions in light water reactors (LWRs).

Phase decomposition and bubble evolution in Xe implanted U₃Si₂ at 450°C

Journal Article Miao, Yinbin ; Harp, Jason ; Mo, Kun ; ... - Journal of Nuclear Materials

We report on the microstructure investigations of a U₃Si₂ specimen implanted by 84 MeV Xe ions at 450°C. In the region that corresponds to the highest irradiation dose, U₃Si₂ was found to decompose into a Si-enriched nanocrystalline USi matrix phase and a U-enriched amorphous inclusion phase. Density functional theory (DFT) calculations were used to help understand the decomposition mechanism. Xe bubbles of different morphologies were observed in USi nano-grains, on USi grain boundaries, and phase boundaries. Original U₃Si₂ micro-grains were preserved on both sides of the irradiation damage peak region within the sample, implying a radiation dose threshold for decompositionmore »« less

Radiation-induced grain subdivision and bubble formation in U₃Si₂ at LWR temperature

Journal Article Yao, Tiankai ; Gong, Bowen ; He, Lingfeng ; ... - Journal of Nuclear Materials

Here, U₃Si₂, an advanced fuel form proposed for light water reactors (LWR), has excellent thermal conductivity and a higher fissile element density. However, limited understanding of the radiation performance and fission gas behavior of U₃Si₂ is available at LWR conditions. This study explores the irradiation behavior of U₃Si₂ by 300 KeV Xe⁺ ion beam bombardment combining with in-situ transmission electron microscopy (TEM) observation. The crystal structure of U₃Si₂ is stable against radiation-induced amorphization at 350 °C even up to a very high dose of 64 displacements per atom (dpa). Grain subdivision of U₃Si₂ occurs at a relatively low dose ofmore »« less

Microstructure investigations of U 3 Si 2 implanted by high-energy Xe ions at 600 °C

Journal Article Miao, Yinbin ; Harp, Jason ; Mo, Kun ; ... - Journal of Nuclear Materials

The microstructure investigations on a high-energy Xe-implanted U3Si2 pellet were performed. The promising accident tolerant fuel (ATF) candidate, U3Si2, was irradiated by 84 MeV Xe ions at 600 degrees C at Argonne Tandem Linac Accelerator System (ATLAS). The characterizations of the Xe implanted sample were conducted using advanced transmission electron microscopy (TEM) techniques. An oxidation layer was observed on the sample surface after irradiation under the similar to 10(-5) Pa vacuum. The study on the oxidation layer not only unveils the readily oxidation behavior of U3Si2 under high-temperature irradiation conditions, but also develops an understanding of its oxidation mechanism.

TEM Characterization of U-Mo Irradiated with High-Energy Xe Ions

Journal Article Ye, Bei ; Jamison, Laura ; Yacout, Abdellatif ; ... - Transactions of the American Nuclear Society

U-Mo alloys (with 7-10 wt.% Mo) with a low U-235 enrichment (< 20%) have been developed to be used in high-performance research and test reactors, replacing the current highly enriched uranium (HEU) fuels. A number of in-pile irradiation tests of U-Mo fuels show that drastic microstructural changes occurred during reactor irradiation, including the formation of U-Mo-Al interaction products and large gas-filled pores. These microstructural changes might lead to breakaway swelling and deterioration of plate mechanical integrity. Hence, it is critical to understand the underlying mechanisms of these microstructural changes in order to improve the irradiation behavior of UMo fuels. Heavymore »« less
Microstructure Investigations of U{sub 3}Si{sub 2} Irradiated by Heavy Ions at LWR Temperatures

Journal Article Miao, Yinbin ; Mo, Kun ; Yacout, Abdellatif M. ; ... - Transactions of the American Nuclear Society

Searching for a nuclear fuel material with enhanced accident tolerance compared to the conventional UO{sub 2} fuel is one of the key objectives of the accident tolerant fuel (ATF) campaign. Having both high thermal conductivity and high uranium load, U{sub 3}Si{sub 2} is expected to provide lower operating temperature/stored energy and advantageous neutron economy as a light water reactor (LWR) fuel material. Therefore, U{sub 3}Si{sub 2} has been regarded as a promising candidate fuel material by the ATF community. To evaluate the qualification of U{sub 3}Si{sub 2} as an ATF fuel in LWRs, its fuel performance during both steady-state operationmore »« less
