摘要： A refueling machine within a nuclear reactor facility includes an inner mast or gripper tube (12) to the bottom of which is secured a gripper assembly (16). An actuator tube (20) controls the gripper mechanisms of the gripper assembly (16), and in order to insure proper and accurate alignment of the gripper mechanisms with the fuel assembly nozzles, a television camera (26) is mounted within the actuator tube (20). A television monitor (34) is operatively connected to the television camera (26), the monitor (34) being disposed upon the refueling machine personnel trolley. The television camera (26) is removably mounted within the actuator tube (20) by a bayonet-type system which includes camera housing lugs (78) which are adapted to pass through slots (76), subsequent to which the camera housing (28) and the lugs (78) are rotated 90.degree. whereby the lugs (78) are seated within recesses (80). The mounting system further includes shock absorbing spring systems (52, 62) for isolating the camera (26 ) for vertically upwardly and vertically downwardly directed shock loads.

摘要： A refueling machine (100) is provided with a latching/unlatching rod (116) which is provided with a hexagonally configured head portion for mated engagement with a hexagonally configured socket (34) defined within a latching/unlatching screw (22) of a fuel assembly (10) whereby the fuel assembly (10) may be securely mechanically connected to the lower core support plate of the reactor internals. The latching/unlatching rod (116) is fixedly connected to a housing (118) which is co-axially disposed within a torque tube (140), the latter of which is fixedly secured to the lower end of a spur gear (130). The spur gear (130) is rotatably engaged with a drive spur gear (148) through means of an idler gear (128), whereby torque is transmitted to the torque tube (140). The torque tube (140) has a square-shaped configuration in cross-section, and the housing (118) has similarly configured flanged portion (144, 146) for cooperation therewith whereby rotary torque is transmitted to the housing (118) and the latching/unlatching rod ( 116). The housing (118), latching/unlatching rod (116), and torque tube (140) are all co-axially disposed within the refueling machine gripper tube (108) and outer stationary mast (102), and a dual winch drive system (112, 124) is provided for independently controlling the vertical movements of the gripper tube (108) and latching/unlatching rod (116), respectively.

摘要： A refueling machine (10, 100) within a nuclear reactor facility includes an outer stationary mast (12, 112) upon which are mounted a plurality of light sources (28, 128), inclined mirrors (36, 136), and television cameras (24, 124) for scanning a fuel assembly (32) for the existence of any defects or damage as the fuel assembly (32) is being withdrawn from the reactor core into the stationary mast (12, 112). In a first embodiment, the light sources (28), mirrors (36), and cameras (24) are mounted upon a sleeve (14) clamped about the lower end of the stationary mast (12), while in a second embodiment, the light sources (128), mirrors (136), and cameras (124) are mounted upon a basket-type framework (178) which is suspendingly supported upon the stationary mast (112) by support cables (158). A fixture (176) can support the framework (178) in an off-the-mast mode so as to permit remote-controlled maintenance or repair of the light sources ( 128), mirrors (136), or cameras (124). The mirrors (36, 136) may be eliminated and the light sources re-oriented so as to illuminate the reactor core and thereby facilitate the insertion of a fuel assembly (32) within the reactor core. Television monitors and tape recorder apparatus (168) are disposed upon the refueling machine trolley (150) for remote viewing of the scanned fuel assembly or viewing of the reactor core during an insertion mode of the refueling operation.
