Abstract

1,010,901. Fuel elements. UNITED KING- DOM ATOMIC ENERGY AUTHORITY. Feb. 20, 1962 [March 3, 1961], No. 7937/61. Heading G6C. A nuclear fuel element comprises a sheathing encasing the fuel and containing a heat transfer medium which is liquid at the operating temperature of the element, a gettering material having an affinity for extraneous substances in the heat transfer medium, such as oxygen and hydrogen which are potentially deleterious to the sheathing, being included in a non-structural role to contact this medium. By way of example, a fast reactor fuel element comprises annular fuel segments 11 and a breeder segment 14 housed between an inner vanadium sheath 12 and an outer niobium sheath 13, the outer sheath 13 being welded to a niobium plug 16 with a free space 17 between the breeder segment 14 and the plug 16. Screwed into the top of the plug 16 is a stainless steel end fitting 18 pierced by holes 20 giving entry for liquid sodium coolant to the inner flow channel through the element. Holes 23 permit the liquid sodium to pass from the outside of the fuel element to the free space 17 which contains the gettering material in the form of a tube 21 of zirconium or titanium. When the element is in use in a reactor, the sodium filling in space 17 remains virtually unchanged, sodium being expelled and returned through the holes 23 only to the extent induced by expansion and contraction. The invention further comprises a method of sheathed fuel element manufacture in which a liquid heat transfer medium for thermally bonding the sheathing with the fuel is brought. during introduction into the sheathing, into contact with a gettering material which has an infinity for unwanted impurities in the heat transfer medium and is incorporated in non- structural role internally of the fuel element, the fuel element being heated to a temperature favourable to the gettering of such impurities. Specification 778,881 is referred to.
