Abstract

Los aparatos móviles se mueven dentro del fluido contaminado para crear flujos de fluido contra estructuras que remueven y evitan la deposición de contaminantes en las superficies de la estructura sumergidas en el fluido; los flujos perturbadores en agua pueden exceder aproximadamente 2 m/s para partículas de radionúclidos y solutos encontrados en plantas nucleares; los aparatos móviles incluyen líquido presurizado de una bomba o fuente presurizada que se pueden tratar química o térmicamente para aumentar al máximo la remoción por deposición; cuando se rocía el líquido presurizado para crear el flujo de deposición-remoción, los aparatos móviles se pueden autopropulsar dentro del fluido alrededor de toda la superficie que se va a limpiar; los aparatos móviles incluyen filtros codificados para remover los contaminantes que se mueven en el refrigerante por medio del flujo, y al tomarlos en el fluido ambiental, permiten dicha filtración del fluido ambiental junto con un volumen más grande de flujo y propulsión; la propulsión y el líquido presurizado a su vez mejoran la toma de fluido ambiental.
