Abstract

Mejoras introducidas en el objeto de la patente principal nº 399.840, presentada el 16 de Febrero de 1.972, sobre: Procedimiento y aparato para la limpieza de elementos de instalaciones de centrales nucleares, humedecidas con H2O o bien D2O durante el servicio, en especial para la descontaminación de regiones con contaminación radioactiva, empleándose según el principio de la técnica del chorro de arena, partículas de anhídrico bórico, con ayuda de una corriente de gas a presión para rebajar mecánicamente las caras a limpiar hasta la capa de pasivación del material base, y desprendiéndose y retirándose mediante agua de lavado los restos del producto del chorro, caracterizadas porque para la aspiración de la cantidad principal del medio del chorro y de las partículas chorreadas de la zona de tratamiento, y como filtro, se emplean despolvoreadores de corriente rotativa.
