An experimental technique has been developed which overcomes the two major problems common to liquid metal solubility measurements,namely,maintaining the integrity of the samples during transfer of the liquid sodium from container to whatever device is used for analysis and detecting solute at very low concentration in liquid sodium.The solubility of uranium in liquid sodium has been measured over the temperature range 150～400℃,by equilibration and sampling technique,the solubility of uranium is approximately 0.00001%.
