Abstract
Weight fractions of plutonium isotopes in samples of lava-like fuel-contain ing masses (LLFCMs) are determined, The experimental values exceed the calc ulated data in statistically significant measure. The abnormal content of p lutonium isotopes in LLFCMs is explained by formation of uranium-zirconium- oxygen phases by the reaction between the plutonium-enriched periphery of t he fuel pellets with the interior of the zirconium cladding of the fuel rod in an inert or reducing medium.
