Abstract
1,248,932. Fuelling reactors. UNITED KINGDOMATOMIC ENERGY AUTHORITY. 16 April, 1969 [3 May, 1968; 23 May, 1968], Nos. 21175/68 and 24738/68. Heading G6C. A pressurized water reactor 1 contained within shielding 10 has coolant tubes 3 receiving fuel element assemblies 2. The tubes 3 have extensions 11, each including a spherical plug valve 15 and a flap valve 14, the valves 14 being situated at the bottom of a pond 6 surmounting the reactor. A fuelling machine 4 movable on a trolley 20 mounted on a carriage 22 has a casing 16 provided with a telescopic nose 17. The casing 16 is filled with water through the nose 17 by immersion of the casing in the pond 6 and to perform a fuelling operation the casing is moved so that the nose 17 is sealed either to the selected tube extension 11 or to a selected fuel storage tube 24 extending from the pond into the shielding 10. A winch 19 enables a fuel element assembly 2 to be lifted into a rotatable magazine 18 having two compartments. In a fuelling operation one of the magazine compartments is initially filled with a new fuel element assembly 2 obtained from a tube 24. The nose 17 is sealed to an extension 11 after opening the valve 14, the valve 15 is opened and the irradiated fuel element assembly in the tube 3 is raised into the empty magazine compartment. The magazine 18 is rotated and the new fuel element assembly is lowered into the tube. Finally, the irradiated fuel element assembly is deposited in a tube 24. The individual bundles 7 of an assembly 2 may be shuffled in a machine 25 centrally pivoted about a horizontal axis. A hoist 29 enables fuel element assemblies to be transferred between the machine 25 and tubes 24 and between the machine 25 and storage racks 26 for irradiated bundles 7 situated in a pond extension 27. In a modification (not shown), the valves 14 are replaced by plugs and the nose 17 has a closure valve. The plugs are retained by latches in the extensions 11 and a plug is released, after sealing the nose 17 to the extension, by increasing the pressure in the casing 16 so that it exceeds the pressure in the reactor.
