Available in PDF, EPUB and Kindle. Book excerpt: An analysis was performed of the three existing measurements of the thermal conductivity and thermal diffusivity of molten uranium dioxide. A transient heat transfer code (THTB) was used for this analysis. A much smaller range of values for thermal conductivity than originally reported was found: the original values ranged from 2.4 to 11 W . m−1 . K−1, with a mean of 7.3 W . m−1 . K−1, whereas the recalculated values ranged from 4.5 to 6.75 W . m−1 . K−1, with a mean of 5.6 W . m−1 . K−1.

Available in PDF, EPUB and Kindle. Book excerpt: Data on thermophysical properties of solid and liquid UO2 have been reviewed and critically assessed to obtain consistent thermophysical property recommendations for inclusion in the International Nuclear Safety Center Database on the World Wide Web (http://www.insc.anl.gov.). Thermodynamic properties that have been assessed are enthalpy, heat capacity, melting point, enthalpy of fusion, thermal expansion, density, surface tension, and vapor pressure. Transport properties that have been assessed are thermal conductivity, thermal diffusivity, viscosity, and emissivity. Summaries of the recommendations with uncertainties and detailed assessments for each property are included in this report and in the International Nuclear Safety Center Database for peer review. The assessments includes a review of the experiments and data, an examination of previous recommendations, the basis for selecting recommendations, a determination of uncertainties, and a comparison of recommendations with data and with previous recommendations. New data and research that have led to new recommendations include thermal expansion and density measurements of solid and liquid UO2, derivation of physically-based equations for the thermal conductivity of solid UO2, measurements of the heat capacity of liquid UO2, and measurements and analysis of the thermal conductivity of liquid UO2.

This book was released on 2012 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The Fuel Cycle Research and Development program's Advanced Fuels campaign is currently pursuing use of ion beam assisted deposition to produce uranium dioxide thick films containing xenon in various morphologies. To date, this technique has provided materials of interest for validation of predictive fuel performance codes and to provide insight into the behavior of xenon and other fission gasses under extreme conditions. In addition to the structural data provided by such thick films, it may be possible to couple these materials with multilayer laser flash analysis in order to measure the impact of xenon on thermal transport in uranium dioxide. A number of substrate materials (single crystal silicon carbide, molybdenum, and quartz) containing uranium dioxide films ranging from one to eight microns in thickness were evaluated using multilayer laser flash analysis in order to provide recommendations on the most promising substrates and geometries for further investigation. In general, the uranium dioxide films grown to date using ion beam assisted deposition were all found too thin for accurate measurement. Of the substrates tested, molybdenum performed the best and looks to be the best candidate for further development. Results obtained within this study suggest that the technique does possess the necessary resolution for measurement of uranium dioxide thick films, provided the films are grown in excess of fifty microns. This requirement is congruent with the material needs when viewed from a fundamental standpoint, as this length scale of material is required to adequately sample grain boundaries and possible second phases present in ceramic nuclear fuel.

Available in PDF, EPUB and Kindle. Book excerpt: The theories of heal transfer in insulators are viewed and discussed relevant to UO/sub 2/. As the rate of heat transfer from a reactor core is determined largely by the thermal conductivity of the fuuel, this coefficient is of paramount importance in improving the efficiency of an installation. There is no theoretical basis to expect small or moderate chemical additions to increase the thermal conductivity of UO/sub 2 when the oxide is classed as an insulator. Large additions of a phase having a high thermal conductivity have been found to increase the net conductivity. Such systems were two phase and had poor sintering cjaracterostocs/ cpmsoderomg UO/sub 2 as a potential oxidic semiconducotor, there is possibility of increasing the themnal conductivity by proper doping. Thermal conduction by intrinsic carriers was treated experimentally and theoretically, and the conductiivity values of the two cases do not presently agree, ie., the Wiedemann-Franz law is not obeyed. The extrinsic case such as a doped urements indicate that doping UO/sub 2/ with Y/sup +3/ and Nb/sup +5/ increases the thermal conductivity. These data are sparce; the magnitude of the increase and its dependence upon impurity concentration and temperature have not been determined. (auth).
