Abstract
699,855. Nuclear reactors. MINISTER OF SUPPLY. Oct. 27, 1949 [Nov. 27, 1948], No. 27626/49. Class 39(iv) Pellets to be subjected to neutron irradiation are placed in receptacles in a plug longitudinally movable in a bore extending to the core of an atomic pile. The pellets are fed to and removed from the receptacles by gravity through inclined passageways in the outer concrete layer. A mechanical and electrical interlock system prevents both the treatment of pellets until a pellet receiving flask has been attached to the outer passage and the presence of two pellets in the inlet passage at the same time. As shown, the plug 14, having pellet receptacles 15, is movable by handwheel 20 along the bore 13 extending from wall X to core Y. A pellet to be irradiated is inserted in the outer end of the inlet passageway 10 down which it rolls to the receptacle 15. After treatment, the receptacle containing the pellet is positioned opposite the inner end of the outlet passageway 12, the plug 14 is turned 180 degrees by handwheel 35 and the pellet falls into 12 and rolls to the pile outer surface. When the pellet receiving flask is in position at the outer end of 12, the plug 14 may be mechanically freed of longitudinal movement in or out of a pile. A locating key is manually disengaged from 14 which is then moved longitudinally by handwheel 20 until the required receptacle registers with the inner end of 10. The key is then engaged with 14 and the electrical interlock system simultaneously energized. Rotation of handwheel 35 through 180 degrees inverts receptacle 15, the pellet therein rolls into 12 towards the receiving flask at the pile outer surface X and simultaneously an electrically operated gate at the inlet of 10 is operated to receive a pellet. Further rotation of 35 at this stage will not effect repeated operation of the gate to direct several pellets into the passageway simultaneously. A manually adjusted handle 45 is now operated to free the pellet from the gate and to release a second gate in 10, thereby permitting the pellet to roll into 15. The locking relay of the locating key of 14 is released, the locking system is de-energized and 14 may be set to a fresh position.
