Title (DE) HÜLLROHR AUS FERRITISCH/MARTENSITISCHEM ODER AUSTENITISCHEM STAHL FÜR KERNBRENNELEMENTE/-STOFFE UND VERFAHREN ZUR NACHBEHANDLUNG EINER HOCHTEMPERATURGEEIGNETEN FeCrAl-SCHUTZSCHICHT DARAUF
(EN) CLADDING TUBES MADE OF FERRITIC/MARTENSITIC OR AUSTENITIC STEEL FOR NUCLEAR FUEL ELEMENTS/FUELS AND METHOD FOR SUBSEQUENTLY TREATING A FECRA PROTECTIVE LAYER THEREON THAT IS SUITED FOR HIGH TEMPERATURES
(FR) GAINE EN ACIER FERRITIQUE/MARTENSITIQUE OU AUSTENITIQUE POUR COMBUSTIBLES/ELEMENTS COMBUSTIBLES NUCLEAIRES ET PROCEDE DE TRAITEMENT POSTERIEUR D'UNE COUCHE DE PROTECTION A BASE DE FECRAL ADAPTEE A DES TEMPERATURES ELEVEES APPLIQUEE SUR CELLE-CI
Abstract:
(DE) Hüllrohre aus ferritisch/martensitischem oder austenitischem Stahl für Kernbrennelemente/-stoffe sind auf der Kühlmittelseite mit einer LPPS- FeCrAl-Schicht versehen, die mit gepulsten Elektronenstrahlen auf dem Hüllrohr umgeschmolzen und angeschmolzen wird. Damit kann flüssiges Blei oder können flüssige Bleilegierungen als metallisches Kühlmittel mit einer Temperatur bis zu 800°C problemlos kontaktieren.
(EN) Cladding tubes made of ferritic/martensitic or austenitic steel for nuclear fuel elements/fuels are provided with an LPPS- FeCrAl layer on the coolant side, this layer being remelted on and melted onto the cladding tube by means of pulsed electron beams. This enables molten lead or molten lead alloys serving as a metallic coolant having a temperature of up to 800 °C to be contacted in a problem-free manner.
(FR) L'invention concerne des gaines en acier ferritique/martensitique ou austénitique destinées à des combustibles/éléments combustibles nucléaires, ces gaines étant pourvues, du côté du fluide de refroidissement, d'une couche de FeCrAl LPPS qui est fondue autour de la gaine et sur celle-ci au moyen de faisceaux électroniques pulsés. Cette couche de protection peut être mise en contact sans problème avec du plomb liquide ou des alliages de plomb liquides servant de fluide de refroidissement métallique à une température pouvant atteindre 800°C.
