Zusammenfassung:	FIELD: technological processes. ^ SUBSTANCE: method includes provision of technological centering blind hole on armored end of fuel cartridge. Then adhesive migration-resistant sublayer is applied on fuel cartridge, which is installed and aligned in die mold. Die-mold contains chamber and gate cover equipped with centering projection that contacts with centering hole. Then armoring material is injected under melt pressure into clearance between die mold and fuel cartridge. At that after charge armoring in casting machine is completed, plug made of thermoplastic armoring material used for charge armoring is pasted into cartridge centering hole. ^ EFFECT: development of method for armoring of charges with centering hole on armored end of fuel cartridge that provides satisfactory quality of charges armoring and reduction of smoke flap in the end of charge operation. ^ 3 cl, 7 dwg
