Abstract: 1,250,316. Controlling reactors. ATOMIC POWER CONSTRUCTIONS Ltd. 6 Aug., 1969 [30 Aug., 1968], No. 41685/68. Heading G6C. In a method of delatching a nuclear reactor control rod from its actuating mechanism, the delatching action also functions to couple the actuating mechanism to an associated control rod guide tube prior to withdrawal of the guide tube from the vicinity of the reactor core. As shown, the top of the control rod 1 has attached to it a tube 2 with an outwardly flared end 2a and also tine couplings 3 formed as flexible fingers cut in the wall of a sleeve 3b attached to the control rod 1. A control rod guide tube 7 is preferably the lowermost portion of a telescopic control rod guide tube. The lowermost end of guide tube 7 seats during normal reactor operation on a seating 8 in the top shield 5 of the reactor core adjacent a cam surface 8a. The lower end of the guide tube 7 accommodates two pivoted hooks 9, and has an internal annular cam surface 10. The control rod 1 is positioned by means of a hoist rope or tape 13 which is connected to the control rod via hook-shaped extensions 11 of the couplings 3, and a coacting hook 12 on a hoist latch unit 14. In order that unimpeded handling of replacement fuel may be carried out, it is necessary to clear the space between the top face of the reactor core and the reactor pressure vessel of all apparatus, with the control rod 1 fully inserted. Upward movement of the guide tube 7 is initiated by means of an auxiliary electric motor and drive unit (not shown) which results in contact between the cam surface 10 and cam surfaces 3d on the couplings 3. The latter are urged radially inwards until the hook-shaped extensions 11 disengage the hook 12. Continuing upward movement of the guide tube 7 causes the top surfaces of the pivoted hooks 9 to engage a cam surface 6 on a core shield extension 4. As further movement takes place, the hooks 9 are urged inwards until they are in a position to be engaged by an upwardly facing channel 15 in the latch unit 14. Upward movement of guide tube 7 is now stopped and the control rod hoist mechanism actuated in an upwards direction, hook 12 moving freely past extensions 11 and channel 15 engaging the hooks 9. Both the latch unit 14 and the guide tube 7 are then withdrawn.
