Abstract

Neutron radiography shows important application potential in the visualization and measurement of multi-phase flow morphologies in new working medium reactors. This article elaborates on the basic principles of neutron radiography measurement methods, provides a comprehensive review of the research progress of neutron radiography technology in traditional light water reactors, lead-bismuth cooled fast reactors, heat pipe cooled reactors, supercritical water reactors, and sodium-cooled fast reactors. It also outlines the future development directions of neutron radiography technology applied to new working medium reactors and provides the basic methodologies for obtaining high-fidelity neutron images and measuring flow patterns.
