ABSTRACT:
A nuclear fuel assembly suitable for use in fast breeders. The fuel assembly has a wrapper tube and a plurality of fuel elements contained in the wrapper tube, each fuel element having a clad tube. The wrapper tube is made of a material which exhibits a larger rate of swelling by neutron irradiation than the material of the clad tube. For instance, the wrapper tube is made of an austenitic stainless steel, and the clad tube is made of an austenitic Ni alloy having a high Ni content. According to this arrangement, it is possible to avoid undesirable contact between the clad tube and the wrapper tube in the last period of the life time of the nuclear fuel.
