Abstract
EL APARATO DE REPARACION DE MUELLE DE REJA ESTA DESTINADO A SER UTILIZADO PARA REPARAR UN MUELLE FORMADO EN UNA TIRA EXTERNA DE UNA REJA DE CONJUNTO DE COMBUSTIBLE NUCLEAR Y QUE TIENE UNA PARTE QUE SOBRESALE ANORMALMENTE HACIA EL EXTERIOR A PARTIR DE LA TIRA. EL APARATO DE REPARACION DE MUELLE DE REJA INCLUYE: UN BASTIDOR DE SOPORTE (46) QUE INCLUYE UN MEDIO (70) PARA SUJETAR EL BASTIDOR A LA TIRA DE REJA EXTERNA DE MODO QUE SE EXTIENDA A TRAVES DEL MUELLE DE REJA QUE HA DE SER REPARADO; UNA CORREDERA EXTERNA (50) MONTADA EN EL BASTIDOR DE MODO QUE PUEDA DESPLAZARSE EN EL A LO LARGO DE UN PRIMER EJE; UNA CORREDERA INTERNA (52) MONTADA EN LA CORREDERA EXTERNA DE MODO QUE PUEDA DESPLAZARSE A LO LARGO DE UN SEGUNDO EJE PERPENDICULAR AL PRIMERO; Y UN MECANISMO DE REPOSICION DE MUELLE (54) SOPORTADO POR LA CORREDERA INTERNA Y QUE PUEDE SER REPARADO, UNA FUERZA CONSTANTE QUE LO HACE VOLVER A SU POSICION NORMAL.
