Abstract

Dispositivo de mantenimiento transversal de las barras combustibles de un conjunto para reactor nuclear, cuyas barras, paralelas entre sí, forman un haz, en cuyo interior son mantenidas según un dispositivo regular por distanciadores transversales, realizados bajo la forma de dispositivos de mantenimiento, que permiten ejercer fuerzas sobre las barras en direcciones transversales para limitar las vibraciones, permitiendo simultáneamente el alargamiento axial de las barras.
