Abstract
The invention concerns a method of producing a cladding tube for nuclear fuel for a nuclear boiling water reactor. According to the method, a tube is formed which comprises an outer cylindrical component () mainly containing zirconium and an inner cylindrical component () metallurgically bonded to the outer component (), wherein also the inner component () at least mainly contains zirconium. The inner component () has a lower recrystallization temperature than the outer component (). The cladding tube is final annealed at a temperature and during a time such that the inner component () substantially completely recrystallizes and such that the outer component () partly recrystallizes but to a lower extent than the inner component (). The invention also concerns a cladding tube, a fuel assembly for a boiling water reactor as well as the use of a cladding tube.
