Abstract

Barra de veneno consumible para uso en un reactor nuclear refrigerado por agua, incluyendo dicha barra una vaina externa tubular de forma alargada, una vaina interna tubular de forma alargada dispuesta concéntricamente en el interior de dicha vaina externa definiendo un espacio anular entre ellas, unos obturadores de extremidad superior e inferior conectados con dichas vainas, y unas pastillas anulares de veneno consumible situadas en dicho espacio anular, caracterizada porque dichos obturadores de extremidad superior e inferior tiene conductos axiales (46, 28), que permiten la comunicación con el interior de dicha vaina interna (30) de modo que el agua refrigerante del reactor pueda circular a través de dicha vaina interna (30) lo que aumenta el contenido de moderador de dicha vaina de veneno consumible.
