Small amounts of plutonium were determined radiochemically after separating plutonium from uranium and fission products by the ion exchange methods. A 7 N nitric acid solution of irradiated uranium was passed through the anion exchange resin, Dowex 1. Uranium and fission prodcomplex of plutonium (IV) was adsorped on the resin bed. Plutonium was eluted with 5% hydroxylamine hydrochloride solution. The solution containing both plutonium and hydroxylamine was passed through the cation exchange resin, Dowex 50, in order to remove the hydroxylamine. After washing the resin with 0.3 N nitric acid, plutonium was cluted with 7 N nitric acid. The synthetic samples containing 2 approximately - 200 mg of uranium and 0 approximately - 4500 dpm of Pu²³⁹ were treated by the above method in order to determine the interferrence of uranium content on the recovery of plutonium. The recovery of plutonium, approximately 92%, is not affected practically with less than 200 mg of uranium. Amounts of plutonium in uranium samples irradiated 66.5 hr in experimental hole No. 2N of JRR-1 and 194 hr in experimental hole No. 13 were 79 dpm Pu/mg U²³⁸, respectively. 4890 dpm Pu/mg U²³⁸ was found in uranium irradiated for 50000 kwh in JRR-1.
