Abstract

Pieza de extremidad de ensamblaje combustible de reactor nuclear, del tipo que comprende una placa perforada (14), un bastidor rígido (16) y paredes laterales (18) que unen el bastidor rígido (16) y paredes laterales (18) que unen el bastidor rígido (16) con la placa perforada (14), estando colocada la citada pieza de extremidad con relación a las estructuras del núcleo del reactor, caracterizada porque las paredes laterales, (18) son elásticamente deformables bajo el efecto de un esfuerzo de compresión del ensamblaje ejercido sobre la pieza de extremidad según el eje longitud del ensamblaje.
