Atomic Energy Aims and scope

Abstract

Methods for developing protection for the jackets of thermionic transducers in nuclear reactors from overloading are proposed and validated. Some properties of the thermal barriers, produced by microplasma spark methods, on the surface of zirconium and tantalum jackets of thermionic transducers are investigated. The microstructural state and phase composition are analyzed. The results of preliminary thermal-cycling tests performed on the alloys, indicated above, with heat-resistant barriers are presented.
