Abstrakt: The results obtained in radiation tests of ß-heat-treated uranium rods at temperatures of 200–300; 450–470; 480G C are given. Dependences of the radiation-growth coefficients Gi on the growth index GI characterizing the grain orientation of the tested specimens were plotted. The elongation component resulting from the radiation growth due to grain orientation was determined. The dependence of the radiation-growth coefficient on the test temperature for weakly-pronounced grain orientations is given. It is shown that the mean values of the linear thermabexpansion coefficient a measured in one direction only, do not provide information on the character and degree of the grain orientation if the latter is not uniaxial.
