Abstract

913,920. Nuclear fuel elements. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. Sept. 12, 1961 [Oct. 21, 1960], No. 36292/60. Drawings to Specification. Class 39 (4). A fuel member enclosed in a protective sheath has a region of preferential initial oxidation on its surface and an element is positioned within the sheath in such a way that an increase in volume on oxidation at this region due to ingress of coolant through a leakage in the sheath causes the element to breach the sheath. The element may be in the form of a plug, of stainless steel for example, a disc of fissile material being disposed above the tip so that a strong signal is received on the fission products detection apparatus immediately the tip protrudes through the sheath. Alternatively, the surface of the element may be roughened to allow fission products to escape freely round it. The sheath may be weakened where it covers the element to make penetration easier. The region of preferential initial oxidation may be produced by a hollow on the outer surface of the fuel member, which hollow may contain an insert of a material more readily oxidizable than the fuel member, e.g. a uranium/platinum alloy containing 1% by weight of platinum. With a tubular fuel member, an element having a bore may extend from a region on the hotter, inner surface across the hollow interior and through the opposite wall, any ingressed fluid present passing through the bore to oxidizing the above region which expands and causes the element to breach the sheath.
