1. A low capacity, gas cooled nuclear reactor installation comprising: a pile of spherical operating elements stationary within a reactor vessel arranged in a cavity;  a cover over said cavity with an access opening disposed in said cover;  a building constructed over at least said cover;  an operating element manipulation device including a transport container positioned on said cover wherein a transport container bottom overlaps said access opening;  a vertically displaceable pebble conveyor line extending from an upper surface of said pile into said transport container;  a blower located between said reactor vessel and said transport container wherein a suction side of said blower is connected to an interior area of said transport container and a pressure side is connected to said reactor vessel.  a bore traversing said transport container bottom extending concentrically with the guide tube;  a ball valve arranged to close said bore.  a bore arranged in said transport container bottom wherein said suction line passes through said bore; and  a ball valve arranged to close said bore.  an intermediate bottom adjacent to said transport container bottom, wherein said intermediate bottom is a filter and configured to support the operating elemetns, and wherein said suction line terminates under said intermediate bottom.  a movable frame exhibiting a hydraulic lifting device adapted to move said transport container between an operational position above the access opening and a transport vehicle located outside the building.  a rotating and advance unit associated with said pebble conveyor line located between said transport container and said reactor vessel.  a bore traversing said transport container bottom extending concentrically with the guide tube;  a ball valve arranged to close said bore.  a rotating and advance unit associated with said pebble conveyor line located between said transport container and said reactor vessel. 2. A reactor installation according to claim 1, wherein a frontal side of said pebble conveyor line facing said pile exhibits a non-horizontal outline and is arranged to be rotated. 3. A reactor installation according to claim 2, wherein said pebble conveyor line is a corrugated tube exhibiting longitudinal inner ribs. 4. A reactor according to claim 1, further comprising a guide tube resembling a walking stick extends approximately vertically from said transport container bottom into an inner area of said transport container and wherein said pebble conveyor line is guided in said guide tube in a vertically displaceable manner. 5. A reactor installation according to claim 4 further comprising: 6. A reactor installation according to claim 1, further comprising: 7. A reactor installation according to claim 6, further comprising a shielding stopper extending into said bore and carried on a closure cover mounted under said transport container bottom. 8. A reactor installation according to claim 6, further comprising releasable inserts in said transport container bottom arranged to allow access to said ball valve. 9. A reactor installation according to claim 1, wherein said transport container further comprises: 10. A reactor installation according to claim 1, further comprising: 11. A reactor installation according to claim 1 further comprising: 12. A reactor installation according to claim 11, wherein said rotating and advance unit is mounted on a housing of a closure slide associated with the reactor vessel. 13. A reactor installation according to claim 11 further comprising a covering sleeve concentrically surrounding said pebble conveyor line extending between said rotating and advance unit and said transport container bottom wherein said covering sleeve defines a clearance space around said pebble conveyor line. 14. A reactor installation according to claim 11, wherein said rotating and advance unit concentrically surrounds pebble conveyor line and comprises a pneumatically controlled stepping piston axially movable independently of said pebble conveyor line, a holder device adjacent to said pebble conveyor line and a drive rotatable with said pebble conveyor line. 15. A reactor installation according to claim 14, wherein said stepping piston and said holding device comprise a plurality of clamping jaws with pneumatically actuated setting elements positioned on surface areas of said holding device and stepping piston facing said pebble conveyor line. 16. A reactor installation according to claim 1, wherein said pebble conveyor line is a corrugated tube exhibiting longitudinal inner ribs. 17. A reactor installation according to claim 1 further comprising: 18. A reactor installation according to claim 5, further comprising a shielding stopper extending into said bore and carried on a closure cover mounted under said transport container bottom. 19. A reactor installation according to claim 5, further comprising releasable inserts in said transport container bottom arranged to allow access to said ball valve. 20. A reactor installation according to claim 16, further comprising:
