A sheathed fuel element, preferably containing uranium carbide as the fuel, comprises a filling between the fuel and the sheath of sodium or other low-melting metal in which powdered Zr or Zr alloy is embedded. The purpose of the Zr or Zr alloy is to prevent the carburation of the sheath, e.g. of steel or a Zr alloy, which would otherwise occur due to the transfer by the low-melting metal of carbon from the fuel to the sheath.</p> |
