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; en donde para rebajar mecánicamente las caras a limpiar hasta la cara de pasivación del material base, se emplean partículas de anhídrico bórico por el principio de la técnica del chorro de arena, con ayuda de una corriente de gas a presión, y los restos del producto del chorro se desprenden y retiran mediante agua de lavado, caracterizadas porque las partículas radioactivas chorreadas, contenidas en el agua de lavado, se recolectan con ayuda de la técnica de filtración, se concentran y se hacen inocuas.
