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 paper considers an experimental device with a neutron converter [1], which provides a change in the neutron spectrum of the IGR reactor from thermal to fast. Successful testing requires a number of thermophysical calculations that sufficiently accurately simulate the thermal state of the experimental device and make it possible to justify the safe conditions of the experiment. The paper presents the results of non-stationary calculations of the thermal state of an experimental device with a neutron converter with energy release both in fuel and in structural materials that simulate nuclear fission energy in fuel elements and the effect of instantaneous and delayed gamma radiation on structural materials.
