Beschreibung
Zusammenfassung:	The invention concerns a control rod configured for a nuclear power light water reactor of the BWR or PWR kind. The control rod contains absorber material. At least 50%, with respect to weight, of the absorber material that is in the control rod is in the form of hafnium hydride. The invention also concerns the use of such a control rod during operation in a nuclear power light water reactor of the BWR or PWR kind. L'invention concerne une barre de commande configurée pour un réacteur nucléaire à eau légère du type à eau bouillante (Boiling Water Reactor, BWR) ou à eau sous pression (Pressurised Water Reactor, PWR). La barre de commande contient un matériau absorbant. Au moins 50% en masse du matériau absorbant présent dans la barre de commande se trouve sous forme d'hydrure de hafnium. L'invention concerne également l'utilisation d'une telle barre de commande pendant l'exploitation d'un réacteur nucléaire à eau légère du type BWR ou PWR.
