FUEL CHARGING AND DISCHARGING DEVICE FOR A NUCLEAR REACTOR
A fuel charging and discharging apparatus for a bidirectional horizontally fueled gas cooled reactor has two charge-discharge machines and two centrally interrupted horizontal static track systems, one opposite each fueling face of the reactor within the pressure vessel. These charge-discharge machines run on the track systems. Two centrally intersecting vertical static track systems extending upward from the pressure vessel in two vertical elevator shafls are equipped with isolating valves and shielding gates. Two elevator dollies running on the vertical static tracks carry two horizontal tracks which can be interlocked within the central interruption of any corresponding pair of the horizontal static tracks. Two guide sheave dollies rest on the tops of the elevator dollies but are stopped at the junctions of the elevator shafts and reactor vessel so that they do not enter into the latter. Two enlargements on the tops of the elevator shafts enclose the machinery for raising, lowering, and locking the elevator dollies in the horizontal tracks, the machinery for reeling in and paying out hoses and cables from static bulkhead connections to the charge- discharge machines, gas locks and shielding gates through which new fuel elements are inserted, spent fuel element tippers, and the inlet ends of spent fuel element discharge pipes. The two spent fuel element discharge pipes are arranged to be emptied through a two valve fluid lock and liquid expansion tank into a fluid-filled spent fuel element flask. (NPO)
