Abstract

Barra de veneno combustible destinada a ser utilizada en un conjunto de combustible de reactor nuclear, que incluye un par de tubos dispuestos concéntricamente (12, 14) que presentan un espacio anular (22) entre ellos con unas pastillas de material de absorción de neutrones (24) dispuestas en dicho espacio anular (22), y unos obturadores (16, 18) montados en las extremidades opuestas de la barra (10) y que cierran herméticamente el espacio (22) que contiene dichas pastillas (24) y un dispositivo de retención de la pila de pastillas (26) en dicho espacio (22) en una extremidad de la barra (10) para mantener dichas pastillas (24) en su posición en el espacio cuando la barra está sometida a fuerzas aplicadas externamente, estando situado dicho dispositivo de retención de modo que se apoye contra la pastilla de extremidad en dicha pila, caracterizada porque dicho dispositivo de retención está constituido por elementos de muelle en forma de C que tienen unos salientes radiales separados circunferencialmente que aplican unas fuerzas radiales contra la superficie de uno de dichos tubos (12, 14).
