Abstract

1,174,253. Fuelling reactors. CANADIAN GENERAL ELECTRIC CO. Ltd. 16 Nov., 1966 [20 Nov., 1965 (2)], No. 51402/66. Heading G6C. A fuelling arrangement for a pressurized water-cooled reactor (not shown) includes a fuelling machine 20, Fig. 1, which may be coupled by a snout 22 at its upper end either to the lower end of a selected calandria tube 100, Fig. 5, extending downwardly from the reactor or to the lower end of a fuel receiving tube 221 extending downwardly from a fuel sorting machine 219, Fig. 7, the lower ends of the tubes 100, 221 being normally closed by ball valves 120, 224, respectively. The valve 120 when in the closed and partly open position, supports the fuel in the tube 100. Fuelling machine 20.-This comprises a flask 21 resiliently mounted on a carriage 29 in which it may be raised by hydraulic jacks 26 to couple the snout 22 either to a selected tube 100 or to the tube 221. The valves 120, 224 are operated by a motor 90 and shaft 91 on the flask and interlocks are provided (Fig. 6, not shown) to prevent opening of a valve until the flask is filled with heavy water at reactor pressure and to prevent uncoupling of the snout 22 whilst the flask is pressurized. The flask, described in detail with reference to Figs. 3, 4 (not shown), includes a magazine and a ram, this ram penetrating the ball valve 120 or 224 when open or partly open and enabling fuel to be lowered from a tube 100 or 221 into the magazine. The heavy water is circulated through pipes 53, 54 through a heat dissipator. The fuel sorting machine 219 comprises a shielded chamber 220, the fuel receiving tube 221, a fuel dispensing tube 261 and a fuel discharge tube 217. The tubes 221, 261, 217 are displaced at 120 degrees when viewed in plan so that they may be aligned with three similarly displaced chambers 231 of a magazine 230. Fuel element retaining latches 240, 241 provided respectively on the tube 221 and on one of the chambers 231 are operable by a push rod 249 having a handle 253 through a crank 248 and rods 246 pivoted to slidable actuating collars 243, 245. The magazine 230 is rotated by a handle 259 through gearing 255, 256 and when it is rotated the collar 245 is disengaged from its rod 246. The fuel discharge station 265 also includes a push-pull rod 268 for operating the latches 241 when they are at that station. A heavy water coolant supply system 295 comprises a header pipe 296, supplying a spray nozzle 297, together with a circulating pump and heat exchanger (not shown). A weight 286 coupled by a string 287 to a shaft 289 driving an indicator 292 is moved by fuel inserted into the tube 221 and thus the quantity of fuel in the tube is indicated.
