Title: (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
(KO) 핵연료 원소/재료용 페라이트/마르텐사이트 또는오스테나이트 강으로 제조된 피복관 및 피복관 위에 고온에적합한 FeCrAl 보호층을 처리하는 방법
Abstract: front page image
(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. ©KIPO&WIPO 2008
(KO) 핵 연료 원소/재료를 위한 페라이트/마르텐사이트 또는 오스테나이트 강으로 제조된 피복관에는 냉각제 면 위에 LPPS-FeCrAl 층이 제공되고, 이 층은 펄스된 전자 빔에 의해 피복관 위에 재용융된다. 그러므로, 이것은 800℃ 이하의 온도에서 액체 납 또는 액체 납 합금과의 접촉으로도 아무 문제를 유발하지 않는다.
