Development of a method for determining corrosion damage of fuel element claddings of a nuclear power unit by using acoustic resonance method in a hot chamber environment

Abstract

As part of the strategic research program of state corporation Rosatom, carried out by the Technological Platform “Closed Nuclear Fuel Cycle with Fast Neutron Reactors”, a research to equip protective cells with original equipment, including ultrasonic flaw detectors for primary post-reactor non-destructive research of the properties of critical materials of fast neutron reactors, is being performed. In this paper, we present a method developed for determining corrosion damage of fuel claddings by the acoustic resonance method in hot chamber conditions, and a description of the experimental installation.
