文摘

Leaching tests of Th0.87Pu0.13O2 were performed for 9 years in several nitric acid solutions. The high chemical durability of thorium-plutonium oxide solid solutions was confirmed. The solubility of plutonium(IV) was not controlled by the precipitation of plutonium tetrahydroxide in these experiments.
