Data confidence 70 medium
How this score is calculated

It is built from checkable properties of the record itself: whether the article has a DOI, how many independent sources confirmed its data, whether the required fields are filled in, and how recent the latest confirmation is. Disagreement between sources and a missing identifier lower it. A value of 80 or above means the record was published without further checking; 60 to 79 means it is published at reduced confidence, with a manual check advisable. A record verified by an editor by hand is never pushed below 90 by a recalculation. This scores our data about the article, not the article itself.

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.
