Abstract: A method of cleaning a vessel having deposits on an interior surface includes removably bonding an ultrasonic transducer to an external wall of the vessel and using the ultrasonic transducer to produce ultrasonic energy coupled into the vessel wall such that at least a portion of the ultrasonic energy is transmitted to the interior surface.

Abstract: Provided are a range of ultrasonic cleaning assemblies that include radiating surfaces activated by corresponding arrays of planar transducers configured to increase the power applied to a reduced volume of fluid associated with a fuel assembly, thereby increasing that applied power density for improved cleaning. The individual ultrasonic cleaning assemblies may be arranged in a variety of modules that, in turn, may be combined to increase the length of the cleaning zone and provide variations in the power density applied to improve the cleaning uniformity.

Abstract: A filter system and associated methods of filtering utilize a combination of ultrasonically enhanced backwashing and a modified filter media configurations for increasing the specific loading on a portion of the filter media, thereby tending to increase the total particulate holding capacity of the improved filter. Depending on factors such as the filter configuration, the particulate size distribution and the differential pressure that can be maintained across the filter, it is expected that the particulate holding capacity can be more than doubled relative to a conventional filter having similarly configured filter media.
