AbstractThe oxygen potentials at 1273 K of mixed oxide (MOX) fuels with Am and 26 kinds of fission product elements (FPs), simulating low-decontaminated MOX fuel and high burn-up of up to 250 GWd/t, have been measured by using thermogravimetric analysis (TGA). The oxygen potentials for simulated low-decontaminated MOX fuels were higher than the fuels without FPs and increased with increasing simulated burn-up.

SummaryUranium, plutonium and fission products are separated by means of a simple multistage extraction of 20% TBP-carbontetrachloride vs. nitric acid series. In order to enhance the mutual separation, the acidity of the aqueous portions is lowered stepwise. All fission products, plutonium and uranium are obtained in aqueous solutions in the sequence mentioned, leaving no active material in the organic solutions of the extractor. The plutonium fractions contain some fission products and a small amount of uranium. However, uranium is obtained with a fairly high purity. The same organic solutions can be used several times giving more or less the same separated products.
