Spectrometry analysis of fumes of (U0.80Pu0.20)O2 hybrid nuclear fuel samples heated to a temperature of 2000°C

Abstract

The results of the spectrometry analysis of a gaseous cloud that forms over (U 0.80 Pu 0.20 )O 2 hybrid uranium-plutonium fuel samples for reactors, which were heated to a temperature of >2000°C, are described. Samples were heated using a laser facility designed for conducting out of pile experiments with the nuclear fuel. The obtained results will make it possible to empirically forecast the isotopic composition of volley emissions from the reactor core during accidents on the 1000 MW power reactor with the (U 0.80 Pu 0.20 )O 2 hybrid fuel.
