Abstract

Procedimiento para la limpieza de elementos de instalaciones de centrales nucleares, rociados durante el servicio con H20 y D20, respectivamente, en especial para la descontaminación de zonas radioactivamente contaminadas, caracterizado porque, según el principio, de la técnica de chorreado de arena, se chorrean partículas de anhídrido bórico, con ayuda de una corriente de gas comprimido, para el decapado mecánico de las superficies a limpiar hasta la capa de pasivación del material base, disolviendo y eliminando los restos del medio de chorreado por agua de enjuague.
