Nuclear reactor fuel element

摘要

In a nuclear reactor fuel element having fuel rods (32, 33) which contain nuclear fuel, which are guided in penetrations (34) in a head plate (35) and of which at least a portion (32) is mounted in these penetrations (34), and having a fuel assembly channel (30) in which the fuel rods (32, 33) are arranged, which bears with a transverse web (31), which is situated inside in a corner at its upper end, against a corner bolt (37) situated on the top side of the head plate (35), and which is bolted down, together with an angle part (2) which is matched to the fuel assembly channel (30) and is provided outside on two sides of the fuel assembly channel with in each case a leaf spring (9) extending in the longitudinal direction of the channel, on said corner bolt (37) by means of a stud bolt (14) which has an expansion shank (23) of reduced diameter, said stud bolt (14) is assigned captively to the angle part (2) by means of a bolt head (15) on the top side and of a screwed-on compressible nut (16) on the underside of the angle part (2), which is pressed tightly laterally on the stud bolt (14) at a milled-off point (20). <IMAGE>
