Abstract

PURPOSE: To prevent from friction scratches on sheath tube outer circumference surface by making a part in contact with nuclear fuel rod of spacer as a revolving body.
CONSTITUTION: Spacer 2 arranges wire 22 with spring and straight wire 21 in a lattice shape within spacer band 6 which fixed the outer circumference of a plurality of nuclear fuel rods 3. Revolving body 23 in contact with the outer circumference surface of sheath tube 14 of respective nuclear fuel rod 3 is inserted into wire 22 with spring and straight wire 21 to form the contact section. Both ends of mounting section of revolving body 23 of wire 21 with spring are somewhat bent in a bow shape to provide elasticity. Revolving body 23 is forming the cross section of V shape groove in the outer axial direction which rubs to the outer circumference axial direction of nuclear fuel rod 3. For mounting nuclear fuel rod, revolving body 23 is revolving even nuclear fuel rod 3 and revolving body 23 are in contacting, which can be mounted without scratching nuclear fuel rod 3 owing to having elastic wire.
