Spacer for a transportable nuclear fuel rod bundle

The spacer for a nuclear fuel bundle includes unit cells having upper and lower, generally octagonally shaped walls (20,22) connected one to the other by spring leg portions (24,26) along sides thereof 90 DEG apart. The walls (20,22) also carry stops (32,34) in opposition to the sides of the walls (...

Zusammenfassung:	The spacer for a nuclear fuel bundle includes unit cells having upper and lower, generally octagonally shaped walls (20,22) connected one to the other by spring leg portions (24,26) along sides thereof 90 DEG apart. The walls (20,22) also carry stops (32,34) in opposition to the sides of the walls (20,22) to which the spring leg portions (24,26) are connected. By orienting the cells in the spacer such that the majority of the cells have their stops (32,34) lying toward one side of the spacer, the fuel bundle can be disposed in a horizontal position on the one side of the spacers. In that manner, the dead load of the fuel rods and spacers is borne by the stops (32,34) along the underside of each spacer without substantially loading the springs of the spacer cells.
