General experimental method of research of anisotropy of conductive materials
2019, Barzov, A. A., Kondrateva, A. S., Baryshev, G. K., Biryukov, A. P., Tutnov, I. A., Барышев, Геннадий Константинович, Бирюков, Александр Павлович, Тутнов, Игорь Александрович
© 2019 Trans Tech Publications Ltd, Switzerland.The paper devotes a new general experimental method for studying the anisotropy of conducting materials of various functional purposes. The difference between the presented method and the previously known one is in the high rate of anisotropy assessment, ensuring the possibility of anisotropy assessment of the properties of materials by the volume of the sample or product under investigation during their manufacture or operation. The procedure for measuring the anisotropy of electrophysical properties and the results of the study of some samples are presented.
Determination of Effective Temperature at in-pile Study of Nuclear Fuel
2020, Belendryasova, E. G., Panasenko, R. A., Tutnov, I. A., Anufriev, B. F., Maksimkin, A. I., Тутнов, Игорь Александрович, Ануфриев, Борис Федорович, Максимкин, Александр Игоревич
© Published under licence by IOP Publishing Ltd.In this work we describe the method to calculate the creep rate of uranium-gadolinium oxide fuel through the effective temperature of fuel samples. Effective temperature characterizes the creep rate with uneven temperature distribution during operation of fuel. Modern modeling technologies presented in ANSYS software were used to calculate the effective temperature. The calculations are compared with measures from in-pile experiments. The results of this work are extremely important for the licensing of new type of nuclear fuel.
