Spacers for nuclear fuels
Description
Purpose: To obtain fuel spacers capable of surely supporting fuel rods under the conditions used in the reactor and easily inserting the fuel rods upon assembling, by forming elastic support members provided to the spacer for supporting fuel rods with bimetal type composite materials. Constitution: In a nuclear fuel spacer in which elastic support members are disposed to a support lattice made of a plurality of band-lile members assembled into a frame, elastic support points on said elastic support members are formed with composite materials of two metal plates overlapped to each other and having different thermal expansion coefficient (bimetal). The composite material preferably comprises in combination, zircalloy material disposed on the side in contact with the fuel rod and Inconel alloy material (or stainless steel) disposed on the other side.
