Section: claims

1. A method for assembling a core of a reactor, the method which comprises:providing irradiated fuel elements for a reactor core of a pressurized water reactor, the fuel elements not having a channel box on their outer circumference;reusing the irradiated fuel elements in accordance with a given loading plan;inserting bent ones of the irradiated fuel elements at an edge of the reactor core; andorienting the bent ones of the irradiated fuel elements inserted at the edge of the reactor core such that a bent side of the fuel elements is oriented toward an outer side of the reactor core. 2. The method according to claim 1, which comprises providing, in accordance with the loading plan, fuel elements having a reactivity below a mean reactivity of the reactor core in positions at the edge of the reactor core. 3. The method according to claim 1, which comprises using bent fuel elements in fuel element positions adjacent to fuel element positions at the edge of the reactor core and orienting the bent fuel elements such that a bending of the bent fuel elements faces the edge of the reactor core. 4. A reactor core configuration for a pressurized water reactor freshly reloaded using the method of claim 1, comprising:a reactor core including fuel elements, said reactor core having an outer side and having an edge, said reactor core having fuel element positions at said edge; andirradiated and bent ones of said fuel elements being disposed at said fuel element positions at said edge of said reactor core, said irradiated and bent ones of said fuel elements disposed at said edge of said reactor core having a bent side, and said irradiated and bent ones of said fuel elements disposed at said edge of said reactor core being oriented such that said bent side is at said outer side of said reactor core. 5. The reactor core according to claim 4, wherein:said reactor core has fuel element positions adjacent to said fuel element positions at said edge; andeach of said fuel element positions at said edge and said fuel element positions adjacent to said fuel element positions at said edge is assigned a fuel element selected from the group consisting of a fuel element having substantially no bending and a fuel element having a bending facing away from said reactor core. 6. The reactor core according to claim 4, wherein each of said fuel elements disposed at said edge of said reactor core has a respective fissible mass below a mean value of fissible mass of all of said fuel elements of said reactor core.
