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

This article discusses the results of mechanical testing of highly enriched uranium (HEU) and low enriched uranium (LEU) fuel materials of the IGR reactor after thermal cycling at different temperatures and the quantity of “heating-cooling” cycles. The strength changes in characteristics of LEU and HEU fuel were determined depending on the thermal cyclic test modes.
