Radiation Embrittlement of Tantalum Coating of the Neutron Source Targets
Abstract
The works in the field of radiation materials science of targets for neutron sources based on subcritical assemblies driven with linear accelerators of electrons or protons, the so-called ADS systems, are presented. Currently, electronuclear ADS systems are prototypes of safe 5th-generation nuclear reactors. In connection with the physical start-up of the neutron source installation of the NSC KIPT the target of which is made of tungsten coated with tantalum, the effect of radiation on mechanical properties is considered, and the resource of the tantalum coating of the target is estimated.
