Abstract
UN METODO PARA MITIGAR LA CORROSION GENERAL Y LA INICIACION Y EL CRECIMIENTO DE FISURAS SOBRE LA SUPERFICIE DE COMPONENTES METALICOS EN UN REACTOR NUCLEAR ENFRIADO CON AGUA. UN COMPUESTO FORMADO POR UN METAL NO NOBLE, COMO EL ZIRCONIO O EL TITANIO, SE INYECTA EN EL AGUA DEL REACTOR EN FORMA DE SOLUCION O DE SUSPENSION. ESTE COMPUESTO SE DESCOMPONE EN LAS CONDICIONES TERMICAS DEL REACTOR PARA LIBERAR IONES O ATOMOS DEL METAL NO NOBLE, QUE SE INCORPORAN A LAS SUPERFICIES DE LOS COMPONENTES, INCLUSO EN LAS SUPERFICIES INTERNAS DE LAS FISURAS QUE SE HAN FORMADO. LOS PREFERIDOS SON LOS COMPUESTOS DE ZIRCONIO COMO EL ACETILACETONATO DE ZIRCONIO, NITRATO DE ZIRCONIO Y NITRATO DE ZIRCONILO. EL ZIRCONIO INCORPORADO A LA SUPERFICIE OXIDADA DE UN COMPONENTE METALICO REDUCIRA EL POTENCIAL DE CORROSION ELECTROQUIMICA EN LA SUPERFICIE A UN NIVEL INFERIOR AL POTENCIAL CRITICO PARA PROTEGER FRENTE A LA RUPTURA POR CORROSION INTERGRANULAR SIN LA ADICION DE HIDROGENO.
