This is achieved by the addition of dopant like titania, niobia etc. However, these dopants are considered as impurities which may affect the thermophysical and thermomechanical properties of the fuel. Thermal Conductivity which is one of the important properties controlling the inpile performance of the fuel has been measured for pure UO2 and UO2 containing 0.05wt per cent and 0.1wt per cent TiO2 in the temperature range 900K to 1900K in vacuum. Thermal conductivity was obtained from thermal diffusivity data measured by laser flash method. The paper highlights the experimental results and discusses the effect of TiO2 on the thermal conductivity of UO2 fuel. 5 figures.","Bhabha Atomic Research Centre,Bombay, India","","","","India","1986-01-01","","English","Book","","","","Conference: National symposium on metallography and NDT: interactions in materials evaluation, Bombay, India, 19 Feb 1986","","Medium: X; Size: Pages: 8","","CONF-8602141-","","","https://doi.org/","","2010-05-13","6304729",""
