Title:
NUCLEAR FUEL CLADDING TUBE AND METHOD FOR MANUFACTURING THE SAME
Document Type and Number:
Japanese Patent JP2005114513
Kind Code:
A
Abstract:
To provide a nuclear fuel cladding tube which is superior in high-temperature strength, creep-resistance properties and resistance to irradiation and to corrosion.
The nuclear fuel cladding tube 12, inside which nuclear fuel pellets 11 are loaded, has an inner layer 13 made of a nickel-base alloy and an outer layer 14, located outside the inner layer 13 and made of a metal whose primary ingredient is titanium. After the tubular inner layer 13 is manufactured first, the outer layer 14 is formed, by spraying the miniscule powder of a metal outside the inner layer 13 at a high speed, to have the powder crimp onto the outer surface of the inner layer 13. The outer layer may be made of ceramics.
