An instrument for the determination of the thermal conductivity of highly radioactive materials
Basic data on candidate fuels are needed in the preparation of irradiation experiments on transmutation. Thermal conductivity is an essential parameter in estimating the pin central temperature during irradiation. These data are, therefore, important in the choice of fuel and for the safety study requested by the licensing authorities. The fuels to be investigated in conjunction with transmutation studies usually contain a certain percentage of the highly radioactive minor actinides Am, Np and Cm. This paper describes an instrument which has been developed and installed in a glove box to measure thermal conductivity. The specificity of the instrument originated in the high level of radioactivity of the material to be investigated, which in turn limited the sample size and placed constraints on handling. The equipment used and testing considerations are described and results of the study are provided.
