Abstract

Un método para descontaminar superficies metálicas en un sistema de enfriamiento de un reactor nuclear comprende llevar a cabo una pluralidad de ciclos de tratamiento, donde cada uno de los ciclos de tratamiento comprende: un paso de oxidación en el cual los óxidos metálicos que incluyen radioisótopos en las superficies metálicas se ponen en contacto con una solución acuosa de un oxidante de permanganato; un paso de descontaminación después del paso de oxidación en el cual los óxidos metálicos se ponen en contacto con una solución acuosa de un ácido orgánico seleccionado del grupo que está compuesto por ácido oxálico, ácido fórmico, ácido cítrico, ácido tártrico, ácido picolínico, ácido glucónico, ácido glioxílico y mezclas de los mismos de manera tal de disolver por lo menos parte de los óxidos metálicos y los radioisótopos; y un paso de limpieza en el cual por lo menos los radioisótopos son inmovilizados en una resina de intercambio de iones; en el cual el paso de oxidación comprende por lo menos un paso de oxidación ácida y por lo menos un paso de oxidación alcalina llevados a cabo uno después del otro en el mismo o distintos ciclos de tratamiento; y en el cual la pluralidad de ciclos de tratamiento comprende por lo menos un ciclo de tratamiento que incluye un paso de oxidación a alta temperatura, en el cual la solución de oxidante de permanganato se mantiene a una temperatura de por lo menos 100ºC y en el cual la por lo menos una bomba de líquido refrigerante del reactor se usa para hacer circular y calentar la solución de oxidación dentro del circuito primario, y el sistema de eliminación de calor residual se usa para controlar la temperatura de la solución de oxidante durante el paso de oxidación a alta temperatura.
