Abstract:
The invention relates to nuclear power and can be used in manufacturing of fuel elements for nuclear reactors. A method of sealing nuclear reactor fuel elements is proposed comprising welding one end of a casing with a plug, both of high-chromium steel, loading the fuel element with fuel, and welding a second plug to another end of the casing. The casing is of a high-chromium ferrite-martensite steel and the plug is of a high-chromium ferrite steel. Argon arc welding is carried out at a volume ratio of the materials of the casing and the plug contributing to formation of the metal of the weld seam which allows formation of a ferrite phase in said metal, wherein the ratio is: V 1 /V 2 >18, where V 1  is the volume of ferrite material and V 2  is the volume of ferrite-martensite material. Argon arc welding is carried out at a current of 14-20 A, a speed of 12-15 m/h, an arc voltage of 9-10 W and an argon flow rate of 7-8 1/min. This method provides for the desired quality of the welded joins and simplifies the fuel element manufacturing process.

Claim (Index 2):
The method of  claim 1 , characterized in that the argon arc welding is carried out at a current of 14-20 A, a speed of 12-15 m/h, an arc voltage of 9-10 W and an argon flow rate of 7-8 l/min.
