[en] This report describes the manufacturing method for the copper capsule, which is proposed by KBS for final disposal of spent nuclear fuel. The design and the dimensioning with respect to stress calculation is shortly explained. Alternative casting and forging methods are discussed and compared. The preferred method is conventional static casting and upsetting and strech forging of the block in order to obtain a fine granular structure. Available equipment in the steel industry are considered useful for those operations. The machining of the capsule consists of turning and long hole drilling, which can be performed by available equipment in Swedish workshop industry. Non-destructive tests can be made with ultrasonic technics as the capsule has a fine granular structure. Inserting of fuel and filling with melted lead into the capsule are non-conventional processes, which are based on the experience from fuel handling in nuclear plants and on lead pouring in other industrial applications. Special lead pouring tests have also been made for this particular purpose. The welding of lids is made by electron beam welding. Welding tests has been made with good result. The weld depth is on the limit of what is possible with the present Swedish equipment, but this field is being developed very quickly and welding equipment with higher capacity is already available which will simplify this operation. The ultrasonic test of the welds has been experimentally checked and does not involve any particular problems. (author)
