33、 uranium and plutonium in dissolved solutions of irradiated light water reactor fuels and in samples of high active liquid waste of spent fuel reprocessing plants, prior to their isotopic analysis by e.g. mass spectrometric method (see ISO 82991) or alpha spectrometry (see ISO 114832).This part of I

34、SO 15366, describes a technique for the separation of uranium and plutonium in spent fuel type samples based on chromatographic method. The procedure applies to samples containing 1 g to 150 g Pu (IV) and (VI) and 0,1 mg to 2 mg U (IV) and (VI) in up to 2 ml of 3 moll1nitric acid solution. It is app

35、licable to mixtures of uranium and plutonium in which the U/Pu-ratio can range from 0 up to 200.2 Principle of the methodThe chemical separation is based on a column extraction chromatography using tri-n-octylphosphine-oxide (TOPO) as extractant.34The necessary valency adjustment prior to the separa

36、tion is done with iron(II) sulfate and sodium nitrite. The extraction process is performed in disposable columns loaded with a silica gel powder coated with the TOPO.5Plutonium(IV) and uranium(VI) in 3 moll1nitric acid medium are selectively extracted into the TOPO while americium, the fission produ

37、cts and other interfering elements are not retained. Plutonium is eluted after reduction to the trivalent state with ascorbic acid6; uranium is eluted by an ammonium carbamate solution. Besides the measurement by mass spectrometry, the plutonium fractions are also measured by alpha spectrometry for

38、the determination of the isotopic abundance of 238Pu (mass spectrometry might be biased by residual amounts of uranium in the plutonium fraction) and for checking the recovery of plutonium.In order to ensure favourable kinetics of the chemical reactions, the (gravity) column flow rates should not ex

39、ceed 0,1 mlmin1.Parallel measurement of blank and/or control sample is recommended to verify the analysis.Blanks are run in parallel with the samples to verify the absence of significant external cross-contamination and cross-contamination between samples.Control samples prepared from certified or a

40、nalysed materials are also prepared and separated along with the sample to verify that suitable valency adjustment, isotopic equilibration and separation efficiency are achieved.3 Apparatus3.1 Biological shielding, e.g. shielded glove box or fume cupboard.
