摘要：

During LEU refueling steps the power peaking factors is continuously rising towards the upper safety limits. The next refueling step with three fresh LEU fuel clusters will overtake those safety limits. That for it is necessary to find some methods in order to decrease power peaking; factors. This paper will present such a method based on removal of the central pin from each of fuel cluster in order to rise the specific power on the inner pins and to save less burned-up pins. These pins will be used to complete another two or three fuel clusters.
