摘要： A nuclear reactor fuel assembly including: an upper tie plate having apertures to receive and support fuel rods of a fuel bundle; the fuel bundle includes an array of the fuel rods mounted and housed in the walls of a channel, and a load bearing or non-load bearing debris shield may be mounted in the upper tie plate, wherein the debris shield is porous to prevent the passage of debris. The debris shield is mounted in the frame of the upper tie plate. The debris shield can be either a removable unit, or it can be attached as a permanent integrated structure within the upper tie plate. The upper tie plate frame is also porous, e.g., has small vertical openings to allow fluid to pass through the frame and block passage of debris. The openings in the frame increase the effective flow area of passages through the upper tie plate and thereby compensate or offset any flow restrictions due to the debris shield. Preventing debris falling into the fuel bundle is expected to assure the operational life of the fuel assembly by reducing the risk of fuel rod failure and premature discharge from the reactor core.

摘要： Bei einem Druckwasserreaktor-Brennelement ist durch eine Haltebohrung (30) der Deckplatte eine Hülse (20) mit einem die Deckplatten-Oberseite (B) übergreifenden Flansch vorgesehen, die an einem über die Deckplatten-Unterseite (A) hinausragenden Kragen (23) ein Außengewinde (24) trägt. Eine Buchse (10) am oberen Ende des Führungsrohres (GR) weist ein Innengewinde (13) auf und schlägt mit ihrer Stirnfläche (11) an der Deckplatten-Unterseite (A) an. Ein Profil (12) am Umfang der Buchse greift in ein entsprechendes Gegenprofil (33) der Deckplatten- Unterseite ein. Diese auch für Kühlmittelrohre von Siedewasser-Brennelementen geeignete lösbare Verschraubung erfordert wenig der für Kühlmittelbohrungen (31, 32) erfoderlichen Querschnittsfläche und keinen individuellen Toleranzausgleich der Verschraubungen einer einzelnen Platte.
