| titleOfInvention | Production process of spacers for nuclear reactor |
| abstract | A process for the production of spacers to retain at least a number of elongated rods (5) of fuel in a fuel unit (20) for placement in a reactor (1), in which each spacer (30) surrounds a number of cells (31), each of which has a longitudinal axis (x) and is arranged to receive a fuel rod (5), such that the fuel rod extends parallel to the longitudinal axis (x), in which each of the cells (31) comprises a number of contact surfaces (35) that extend essentially parallel to the longitudinal axis (x) for a contact against the fuel rod (5) to be received in the cell (31) , and wherein the method comprises the step of providing at least two spacers (30), the method comprising the steps of providing a set of mandrels (40) comprising a number of mandrels (42) with associated longitudinal axes (43), mandrels that (42) are arranged on a common base (41) and mandrels (42) are arranged mutually with their essentially parallel longitudinal axes (43), arrange at least two spacers (30) one above the other on the set of mandrels (40), so that the mandrels (42) are arranged through all the cells (31) in all the spacers (30) with the longitudinal axes (43) of the mandrels (42) essentially parallel to the longitudinal axes (x) of the cells (31 ), so that the cells (31) that are arranged on top of each other are interconnected by a common mandrel (42), and heat treat the spacers (30) when arranged on the mandrel assembly (40), deforms that the cells (31) in the spacers (30) fit the mandrels (42), in which the mandrels (42) in the mandrel assembly (40) are placed in a first position before the spacers (30) are arranged on the mandrel set (42), first position in which it is possible to arrange a spacer (30) on the mandrel assembly (40) without the mandrels (42) making contact with the spacer (30), and in which the mandrels (42) in The mandrel assembly (40) is placed in a second position by rotating the mandrels (42) around the longitudinal axes (43) of the mandrels before the heat treatment begins, second position in which the mandrels (42) they make contact with the contact surfaces (35) of the cells (31). |
