Abstract
METODO PARA CERRAR HERMETICAMENTE UNA TOBERA DE RAMA FRIA DE UN RECIPIENTE DE PRESION. CONSISTE EN: A) SUJETAR UN TAPON DE CIERRE AL EXTREMO DE UNA HERRAMIENTA DE INSTALACION (16) DISPUESTA HORIZONTALMENTE, SITUADA POR ENCIMA Y EN ALINEACION CON EL RECIPIENTE DEL REACTOR; B) HACER DESCENDER LA HERRAMIENTA DE INSTALACION DENTRO DEL RECIPIENTE DEL REACTOR HASTA QUE LA HERRAMIENTA DE INSTALACION Y EL TAPON (20) SUJETO A ELLA ESTEN ALINEADOS CON UNA TOBERA (22) DE RAMA FRIA; C) INSERTAR EL TAPON DE CIERRE DENTRO DE LA TOBERA DE RAMA FRIA; Y D) EXPANDIR MECANICAMENTE EL TAPON DE CIERRE PARA EFECTUAR UN CIERRE HERMETICO DENTRO DE LA PORCION CILINDRICA DE LA TOBERA DE RAMA FRIA. TIENE APLICACIONES EN REACTORES NUCLEARES.
