Abstract

Perfeccionamientos en dispositivos de tratamiento térmico para alarga la duración de una vasija de presión, especialmente de una vasija de presión de reactor, cuyo material resistente al calor está sometido por fluencia de neutrones a alteraciones de estructura dependientes del tiempo, del tipo que presenta un dispositivo calentador que puede ponerse en posición, contiguo a las partes de pared a tratar de la vasija de presión, en el espacio interior de la misma, además con una sujeción para el dispositivo calentador que presenta un cuerpo sustentador esencialmente cilíndrico hueco que está alojado en un dispositivo portante mediante el cual puede introducirse por la boca de la vasija a la misma y extraerse de nuevo, estando inundados el espacio interior de la vasija de presión y el espacio del reactor para la introducción y extracción del dispositivo, y estando vaciado de agua de inundación el espacio interior del reactor, exento de estructuras internas, para el tratamiento térmico, caracterizados porque el cuerpo sustentador está desarrollado como cilindro aislante y puede ponerse en contacto hermético mediante superficies de apoyo de su contorno exterior, con el contorno interior de la vasija de presión, de tal manera que delimita un espacio de calentamiento en forma de anillo colindante a las partes de pared a tratar de la vasija de presión, y porque el tratamiento térmico se efectúa estando el espacio del reactor vacío y apantallado hacia fuera mediante arriostramientos de tapa.
