Abstract

991,424. Stamping. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. March 11, 1963 [May 30, 1962], No. 20926/62. Drawings to Specification. Heading B3Q. [Also in Division G6] As a step in the manufacture of a nuclear reactor fuel element, the protective sheath of the element is deformed into intimate contact with the fuel member by external pressurization brought about by a high-energy shock-wave or waves. The shock-wave or waves may be generated by a rod of explosive placed parallel with the assembled fuel element in a water-filled vessel and fired electrically. Alternatively electromagnetic means may be used, the element together with a copper tube in which it is coaxially disposed being positioned within a coil through which a bank of high capacity condensers is repeatedly discharged, thus setting up an intense variable magnetic field. A current is thereby induced in the tube which generates a magnetic field opposed to that set up by the condenser discharges and thereby subjects the tube to a physical force, which force effects deformation of both the tube and the protective sheath of the element. A similar device uses a spark-gap in place of the coil, a tungsten or titanium wire being connected across the gap which is immersed in a cylinder of water close to the element. On discharging the bank of condensers the wire vaporizes to create a high-energy wave front. In the embodiments described, the fuel element comprises a stack of pellets of ceramic fissile material enclosed withing a stainless steel sheath, one or more non- fissile pellets which divide up the stack of fissile pellets being each formed with a circumferential groove into which the sheath is deformed in order to provide a degree of keying. Specification 958,697, and U.S.A. Specification 2,976,907 are referred to.
