Abstract

SE PROPORCIONAN UN APARATO Y METODO PARA PONER EN SERVICIO UNA VARILLA DE MANDO (18) NUCLEAR IRRADIADA BAJO EL AGUA, EN UN ESTANQUE (24) DE SERVICIO DEL EDIFICIO DEL REACTOR. UNA MESA GIRATORIA (68A), CONTENIENDO UNA PLURALIDAD DE HERRAMIENTAS (70) SEPARADAS SE POSICIONA ADYACENTE A LA VARILLA DE CONTROL (18). UNA PRIMERA HERRAMIENTA (70A) ALINEA LA MESA GIRATORIA (68A) RESPECTO AL RODILLO RADIOACTIVO (32) INSTALADO EN LA VARILLA DE CONTROL (18) MEDIANTE UNA ESPIGA RADIOACTIVA (42 A SU TRAVES. LA MESA GIRATORIA (68A) ES GRADUABLE PARA POSICIONAR UNA SEGUNDA HERRAMIENTA (70B) ADYACENTE AL RODILLO RADIOACTIVO (32) Y ESPIGA (42), CON LA SEGUNDA HERRAMIENTA (70B) SIENDO EFECTIVA PARA LIBERAR A LA ESPIGA RADIOACTIVA (42) DE LA VARILLA DE MANDO (18). LA MESA GIRATORIA (68A) ES GRADUABLE PARA POSICIONAR UNA TERCERA HERRAMIENTA (70C) ADYACENTE AL RODILLO RADIOACTIVO (32) Y ESPIGA (42), PARA EXTRAER LA ESPIGA RADIOACTIVA (42) Y EL RODILLO (32) DE LA VARILLA DE MANDO (18). EN POSTERIORES VERSIONES DELA INVENCION, LA MESA GIRATORIA (68A) ES ADEMAS GRADUABLE PARA POSICIONAR UNA CUARTA HERRAMIENTA (70D) ADYACENTE A LA VARILLA DE MANDO (18), PARA MANDRILAR LA APERTURA DE LA ESPIGA (40A, 40B), A CUYO TRAVES SE INSTALO LA ESPIGA RADIOACTIVA (42). LA MESA GRADUABLE (68A) INCLUYE ADEMAS UNA QUINTA HERRAMIENTA (70E) QUE ES GRADUABLE EN POSICION ADYACENTE A LA VARILLA DE MANDO (18) PARA INTRODUCIR UN RODILLO DE REPOSICION Y ESPIGA DE SUSTITUCION AHI DENTRO. LA ESPIGA DE SUSTITUCION SE SUJETA A LA VARILLA DE MANDO (18) POR MEDIO DE UNA SEXTA HERRAMIENTA (70F), SUSTENTADA SOBRE LA MESA GIRATORIA (68A), QUE ES TAMBIEN GRADUABLE EN POSICION.
