Title: NUCLEAR REACTOR FUEL SYSTEMS

Abstract

Homogeneous reactor fuel solutions are reported which provide automatic recombination of radiolytic gases and exhibit large thermal expansion characteristics, thereby providing stability at high temperatures and enabling reactor operation without the necessity of apparatus to recombine gases formed by the radiolytic dissociation of water in the fuel and without the necessity of liquid fuel handling outside the reactor vessel except for recovery processes. The fuels consist of phosphoric acid and water solutions of enriched uranium, wherein the uranium is in either the hexavalent or tetravalent state.

  • A system is described for discharging fuel elements from vertically oriented nuclear reactors by access from the top of the reactor. The upper face of the reactor core assembly is separated from the top shield structure by a space in which the fuel channels terminate. A fuel element discharge channel extends from the same space to a discharge point below the shield structure. A portion of the top shield structure consists of a rotatable wheel upon which a fuel element manipulating machine is mounted eccentrically in such a manner' that it can move between the terminal ends of the fuelmore » channels and the fuel element discharge channel. Fuel elements can thus be removed from the reactor without penetrating the shielding above the reactor. (A.G.W.)« less
  • A fuel element cooling fin design is offered. A transverse circular or close-pitched helical fin on a tubular or rod-shaped element is cut into an oven number of segments per convolution. These segments are bent alternately up and down with respect to the rod axis so that segments registering longitudinally are all bent in one direction and adjacent segments are bent in the other. (T.R.H.)
  • A system for improving heat transfer conditions in gasswept reactor coolant channels containing longitudinally finned fuel elements. Deffectors are provided near the outer ends of the fins for mixing the gas and deffecting it into the spaces between. The deflectors are rings of oblique aerofoil cross section extending around the fins. (T.R.H.)
