Abstract

SE DESCRIBE UN METODO PARA MITIGAR EL CRECIMIENTO DE FISURAS SOBRE LA SUPERFICIE DE ACERO INOXIDABLE U OTROS COMPONENTES METALICOS DE UN REACTOR NUCLEAR REFRIGERADO POR AGUA. UN COMPUESTO QUE CONTIENE UN METAL NOBLE, EJ. PALADIO, SE INYECTA EN EL AGUA DEL REACTOR EN FORMA DE DISOLUCION O SUSPENSION. ESTE COMPUESTO TIENE LA PROPIEDAD DE QUE SE DESCOMPONE BAJO CONDICIONES TERMICAS DEL REACTOR PARA LIBERAR IONES/ATOMOS DEL METAL NOBLE, LOS CUALES SE INCORPORAN O DEPOSITAN EN LA SUPERFICIE INTERIOR DE LA FISURA. EL COMPUESTO PUEDE SER ORGANICO, ORGANOMETALICO (EJ. ACETILACETONATO DE PALADIO) O INORGANICO POR NATURALEZA. EL PALADIO DEPOSITADO EN EL INTERIOR DE UNA FISURA MOSTRARA UN COMPORTAMIENTO CATALITICO INCLUSO SI LA SUPERFICIE BRUTA DEL PALADIO ESTA EMPOBRECIDA BAJO CONDICIONES DE ALTO FLUJO DE FLUIDO. COMO RESULTADO, EL POTENCIAL ELECTROQUIMICO DENTRO DE LA FISURA DESCIENDE A UN NIVEL INFERIOR AL POTENCIAL CRITICO PARA LA PROTECCION CONTRA FISURACION POR CORROSION BAJO TENSION INTERGRANULAR.
