Abstract

Fijación lateral para la placa del núcleo de un reactor de agua en ebullición. Un aparato para estabilizar una placa del núcleo contra la deflexión lateral. Una pluralidad de ensamblajes de cuña de la placa del núcleo (por ejemplo, cuatro) se instalan en la separación circunferencias entre el borde periférico circular externo de la placa del núcleo y la pared cilíndrica circular de la sección media de la cubierta en sus posiciones acimutales respectivas estando acuñados en su lugar con precargas para mantener la separación entre la placa del núcleo y la cubierta, manteniendo la alineación de los ensamblajes de combustible, sirviendo adicionalmente para transmitir las cargas desde el núcleo del combustible nuclear a la cubierta del núcleo en las posiciones acimutales en donde las fijaciones laterales de la cubierta en el exterior de la cubierta entran en contacto con el recipiente a presión del reactor.
