FIELD: process engineering.
SUBSTANCE: invention relates to nuclear power stations and may be used in machine building, electronic and chemical industries for cleaning working surfaces by dispersion, impregnation and other processes. Device case is composed of polyhedral framework composed by rigidly interconnected vertical props and horizontal buckles. N transducers are located at facets of said framework and connected to their assigned ultrasound generators for amplitude-frequency modulation of control rack. Said case is furnished with seat for article to be processed. Sealed transducers with radiators are made of titanium and located at horizontal buckles along housing every facet, nearby each other, to create continuous dense ultrasound field. Transducers arranged at every pair of adjacent facets are connected to ultrasound generators with phase separation.
EFFECT: longer life of working holders and fuel assemblies.
