Beschreibung
Zusammenfassung:	The invention relates to a soluble burnable absorber rod for use in a nuclear fuel assembly. … The rod comprises a tubular member (34) which is sealed at both ends thereof and contains a neutron absorbing material (42), the latter being in the form of a liquid, preferably boric acid with an enhanced concentration of boron isotope B-10. … In communication with the interior space (40) containing the neutron absorbing liquid are a hydrogen getter material (44) disposed adjacent the end plug (50) sealing one end of the tubular member, and a hydride sink (46) formed as an end plug (52) sealing the other end of the tubular member.
