Abstract

PARA PROTEGER LAS BARRAS DE COMBUSTIBLE EN UN ELEMENTO DE COMBUSTIBLE DEL DAÑO POR MEDIO DE CUERPOS EXTRAÑOS EN LA CORRIENTE DE REFRIGERACION, LA INVENCION PROPONE QUE SE COLOQUE UN FILTRO DE PARTICULAS EN EL PIE DEL ELEMENTO COMBUSTIBLE NUCLEAR. ESTE FILTRO CONSISTE EN UNA PLACA (14) DE UNA PIEZA EN DONDE SE HAN FORMADOS AGUJEROS (15) MEDIANTE ELIMINACION ELECTROQUIMICA DEL MATERIAL DE LA PLACA. ESTO HACE POSIBLE LA ELABORACION DE AGUJEROS DE PERFILES GEOMETRICOS Y DIMENSIONES QUE SON DIFICILES DE PRODUCIR MEDIANTE TECNICAS DE FUNDICION O TRABAJOS MECANICOS.
