Abstract

In order to prevent plutonium diffusing through the outer magnesium alloy sheath of a uranium alloy fuel rod, an inner sheath is provided made of an alloy of magnesium containing 0-1 to 5% by weight of aluminium. The inner sheath may be one-tenth to a half the total thickness of the two sheaths. The outer sheath may be made of a Mg alloy containing a small amount of Zr or Zr and Mn. Other components of the inner sheath alloy may be Be, Si and Ce. The fuel can comprising the two sheaths may be made by co-lamination, co-spinning, or co-extrusion.
