Title: Thermophysical properties of U₃Si₅ to 1773 K

Abstract

Possible use of U₃Si₅ as a nuclear reactor fuel requires knowledge of its thermophysical properties as a function of temperature. While limited data is available for U–Si compounds containing higher uranium densities, no investigations of U₃Si₅ have been presented in the literature to date. Here, high purity U₃Si₅ was fabricated to facilitate a set of experiments to determine the coefficient of thermal expansion, heat capacity, thermal diffusivity, and thermal conductivity from room temperature to 1773 K. Each measurement on nearly stoichiometric U₃Si₅ showed the existence of a phase transformation at 723 K, which is not consistent with the most recently published phase diagram.

Corrigendum to “Thermophysical properties of U₃Si₂ to 1773 K”

Journal Article White, Joshua Taylor ; Nelson, Andrew Thomas ; Dunwoody, John Tyler ; ... - Journal of Nuclear Materials

An error was discovered by the authors in the calculation of thermal diffusivity in “Thermophysical properties of U₃Si₂ to 1773 K”. The error was caused by operator error in entry of parameters used to fit the temperature rise versus time model necessary to calculate the thermal diffusivity. Lastly, this error propagated to the calculation of thermal conductivity, leading to values that were 18%–28% larger along with the corresponding calculated Lorenz values.

Thermophysical properties of U 3 Si 2 to 1773K

Journal Article White, Joshua Taylor ; Nelson, Andrew Thomas ; Dunwoody, John Tyler ; ... - Journal of Nuclear Materials

Use of U₃Si₂ in nuclear reactors requires accurate thermophysical property data to capture heat transfer within the core. Compilation of the limited previous research efforts focused on the most critical property, thermal conductivity, reveals extensive disagreement. Assessment of this data is challenged by the fact that the critical structural and chemical details of the material used to provide historic data is either absent or confirms the presence of significant impurity phases. This study was initiated to fabricate high purity U₃Si₂ to quantify the coefficient of thermal expansion, heat capacity, thermal diffusivity, and thermal conductivity from room temperature to 1773 K.more »« less

Phase Equilibria in the TiO{sub 2}-Rich Part of the TiO{sub 2}-CaO-SiO{sub 2}-10 Wt Pct Al{sub 2}O{sub 3}-5 Wt Pct MgO System at 1773 K

Journal Article Wang, Zhen ; Zhu, Qingshan ; Sun, Haoyan - Metallurgical and Materials Transactions. B, Process Metallurgy and Materials Processing Science

The phase equilibria of the TiO{sub 2}-CaO-SiO{sub 2}-10 wt pct Al{sub 2}O{sub 3}-5 wt pct MgO system in the TiO{sub 2}-rich part were investigated experimentally at 1773 K using the high-temperature equilibration–quenching method and the electron probe microanalyses. Through this study, the isothermal section of the above system was obtained containing one liquidus region and five solid–liquid coexistence regions. The primary phase region of anosovite was not only found, but it is the optimal composition region that is most beneficial to the anosovite selective crystallization and separation.

Enthalpies of formation and phase stability relations of USi, U₃Si₅ and U₃Si₂

Journal Article Chung, Cheng -Kai ; Guo, Xiaofeng ; Wang, Gaoxue ; ... - Journal of Nuclear Materials

U–Si intermetallic compounds have drawn great attention due to their potential application as nuclear fuels. However, the thermodynamic properties and phase equilibria of this binary system from ambient to high temperature conditions are not fully understood. Via high temperature oxidative drop calorimetry and detailed characterization of the initial and final phases, we have experimentally determined the standard enthalpies of formation of USi and U₃Si_5.07 at 298 K to be –43.2 ± 6.2 and –43.8 ± 9.0 kJ/mol·atom, respectively. The energetics of the tetragonal USi (t-USi, space group I4/mmm) phase has also been calculated with Density Functional Theory (DFT) for themore »« less

State of knowledge and challenges of U-Si compounds for use in light water reactor accident tolerant fuel designs

Conference White, J. T. ; Wood, E. S. ; Dunwoody, J. T. ; ...

Characterization of the properties of U-Si compounds first required synthesis of high purity material for each of the compositions. The four compounds targeted for investigation in this work were U{sub 3}Si, U{sub 3}Si{sub 2}, USi, and U{sub 3}Si{sub 5}. Specimens of U{sub 3}Si{sub 2}, U{sub 3}Si{sub 5}, and USi with specific geometries for individual testing procedures were prepared using a powder metallurgical method. Thermophysical properties of the U-Si compounds were determined within 100 K of their respective melt point or decomposition temperature. Thermal expansion was determined with a dilatometer, specific heat capacity by the ratio method in a differential scanningmore »« less
