Abstract

UN METODO PARA MITIGAR EL CRECIMIENTO DE GRIETAS EN LA SUPERFICIE DE ACERO INOXIDABLE U OTROS COMPONENTES DE ALEACION EN UN REACTOR NUCLEAR REFRIGERADO POR AGUA, EN EL QUE UNA SOLUCION O SUSPENSION DE UN COMPUESTO QUE CONTIENE UN METAL NOBLE SE INYECTA EN EL AGUA REFRIGERANTE MIENTRAS EL REACTOR NO SE ENCUENTRA GENERANDO CALOR NUCLEAR, POR EJEMPLO, DURANTE EL CIERRE O RECALENTAMIENTO DE BOMBA DE RECIRCULACION. DURANTE EL CIERRE, EL AGUA REFRIGERANTE DEL REACTOR ALCANZA UNA TEMPERATURA TAN BAJO COMO 120 GRADOS F, EN CONTRASTE CON LA TEMPERATURA DEL AGUA DE 550 GRADOS F DURANTE EL FUNCIONAMIENTO NORMAL. DURANTE EL RECALENTAMIENTO DE LA BOMBA, LA TEMPERATURA DEL AGUA ALCANZA 400450 GRADOS F. A ESTAS TEMPERATURAS REDUCIDAS, EL INDICE DE DESCOMPOSICION TERMICO DEL COMPUESTO DE METAL NOBLE INYECTADO SE REDUCE. SIN EMBARGO, LA DESCOMPOSICION INDUCIDA POR RADIACION TAMBIEN SE PRODUCE DENTRO DEL REACTOR. EN PARTICULAR, EL COMPUESTO DE METAL NOBLE PUEDE DESCOMPONERSE MEDIANTE LA RADIACION GAMMA QUE EMANA DEL NUCLEO DE COMBUSTIBLE NUCLEAR DEL REACTOR. EL COMPUESTO DE METAL NOBLE SE DESCOMPONE BAJO CONDICIONES DE RADIACION Y TERMICAS DEL REACTOR PARA LIBERAR ATOMOS/IONES DEL METAL NOBLE QUE SE INCORPOREN O SE DEPOSITEN SOBRE LA PELICULA DE OXIDO FORMADA SOBRE EL ACERO INOXIDABLE Y OTROS COMPONENTES DE ALEACION. COMO RESULTADO, EL POTENCIAL ELECTROQUIMICO DE LA SUPERFICIE DE METAL SE MANTIENE A UN NIVEL POR DEBAJO DEL POTENCIAL CRITICO EN LA PRESENCIA DE NIVELES BAJOS DE HIDROGENO PARA LA PROTECCION CONTRA EL AGRIETAMIENTO DE CORROSION DE RESISTENCIA INTERGRANULAR.
