Definitions
- the invention relates to the field of disposal, transport and manipulation of disposal casks with spent nuclear fuel in an underground system of a deep geological repository equipped with robotic technologies.
- the closest solution to the proposed project is a disposal concept of Swiss society Nagra which also proposes a disposal system of disposal casks with spent nuclear fuel into the horizontal tunnels where in one half of the space profile of the tunnel there is a disposal cask transported in a protective casing from which it is pushed by a hydraulic cylinder onto the shaped bed in front of the casing from which it is then, still in the horizontal position, transported by a gripper manipulator into the area of the second half of the tunnel profile onto the shaped bentonite bed which is already placed in the filling robot.
- the filling robot then returns to the base area, where it must be transformed to another track and interchanged for an injection robot which then freely, by the bulk bentonite, backfills the space between the profile of the disposal tunnel and the outer shell of the disposal cask with spent nuclear fuel.
- the proposed concept according to the invention solves the disposal process unto the disposal borehole though a fully robotized multifunctional system - super-robot, which without the intervention of a human agent solves the complex end manipulation transport, disposal and backfilling process, which diametrically different parameters and functions are accumulated in one robotic system which creates a unique world novel technology, oriented on the project program Industry 4.0, in a partial manner.
- the proposed solution has not only unrivaled technological and utility added value but also an extremely high economic added value compared to other current methods and technologies.
- US 2011/0094815 A1 describes a stack axle assembly as used in a cask transporter or a horizontal storage module (HSM) gantry transporter.
- the stack axle assemblies include a slew gear; an upper bearing; a lower bearing; a vertical cylinder retained by the slew gear, upper bearing and lower bearing; an independent driver wheel and idler wheel revolving on a common shaft/trunnion assembly attached to the bottom of the vertical cylinder; a frame assembly formed on top of the vertical cylinder, the frame assembly including one or more drive motors connecting an upper drive assembly downwardly to a driven assembly mounted between the idler wheel and driver wheel; and a slew driver motor to drive the slew gear.
- EP 3 154 063 A1 describes a technology and logistics system of robotic deep geological disposal of spent nuclear fuel consists of a surface complex, underground complex, and connecting shaft and elevator complex, where the surface complex includes a robotic system of preparation of disposal casks ended by storage of deposit casks, and it is an entrance building for deep geological disposal of disposal casks.
- a storage of bentonite fillings builds on the storage of deposit casks, while the surface complex under the surface of the underground complex is followed by the directed connecting shaft and elevator complex formed by a vertical shaft and an elevator with an elevator cabin with built-in follow-up rails ended by a lower station from which a network of access horizontal corridors is bulit as approaches in geological repositories followed by a system of circular boreholes for storage of disposal casks, where the corridors are equipped with a grid of rails with contact wires.
- the grid of rails with contact wiresis in the underground complex and surface complex is followed by short sections of rails with contact wires in the elevator cabin.
- a part of the surface complex are in addition to storage of disposal casks and storage of bentonite fillings other surface robotic workstations, while in the storage there are stored circular bentonite plugs, bentonite beds and circular bentonite segments, and there is stored also a manipulator of bentonite fillings for loading of the bentonite elements on transport vehicles, and further in the storage of disposal casks there is stored a manipulator of disposal casks for their storage in bentonite bed loaded on transport vehicle with a superstructure.
- a storage robotic vehicle is designated for loading of disposal cask or bentonite filling of different type and their displacement from the connecting horizontal corridor to the storage location in the borehole.

- Preferred embodiments are defined in dependent claims 2-9.
- the advantage of the proposed solution is that the designed robotic technology of disposal of disposal cask into the horizontal boreholes eliminates completely all sliding movements of the disposal cask on the ground.
- the disposal cask with spent nuclear fuel is not pushed into the disposal place in the borehole but it is transferred and laid down gently. This method is very careful to the surface of the disposal cask and less energy consuming.
- Another advantage of the proposed solution is the minimized manipulation with disposal casks in vertical direction which is very energy-efficient.
- Another unquestionable advantage is the simplicity of the entire robotic process, resulting in minimizing the number of special single-purpose machines and devices which are needed for realization of storage of disposal casks with spent nuclear fuel and bentonite prefabricated parts.
- Robotic system 1 of disposal of disposal casks in the deep geological repository includes underground system of corridors and boreholes with railway network 2 with trolley wires for an environmentally acceptable way of disposal of nuclear waste.

- the disposal robot 36 moves on the superstructures 19 of the conveyance vehicles 6 and rotatable superstructure of the vehicle 30 with turntable for conveying the disposal robot 36 which have the same diameter as the construction 9 of disposal borehole, as well as disposal robot 36 moves in the construction 9 of disposal borehole.
- Disposal of disposal casks 3 occurs as follows: First, the circular bentonite fillings 10 are transported individually into the ending part of the construction 9 of empty disposal borehole. This is how the construction 9 of disposal borehole of deep geological repository 5 is prepared, and further it is possible to continue in disposal of disposal casks 3 cyclically.
- the rotatable superstructure 34 of the vehicle 30 with turntable for conveying the disposal robot 36 turns by 90° and there occurs the vertical and horizontal alignment with rotatable superstructure 34 and the borehole offset 61; the rotatable superstructure 34 returns to its original position; superstructures 19 of other vehicles of the set adjust their height vertically to the same level as the rotatable superstructure 34; and the cycle of disposal can be started.
- Disposal robot 36 picks up through the effector 46 for manipulation with bentonite fillings a bentonite bed 11 from the second conveyance vehicle 6, returns to the rotatable superstructure 34 and after rotation by 90° rides to the end of construction 9 of disposal borehole and lays the bentonite bed 11 at full to the last circular bentonite filling 10.
- the disposal robot 36 returns, uses the rotatable superstructure 34, picks up a disposal cask 3 via gripping of the effector 47 for manipulation with disposal casks from the first conveyance vehicle 6, and again it rides in the same way to the construction 9 of disposal borehole, and lays the disposal cask 3 on the bentonite bed 11 at full to the last circular bentonite filling 10.
- this small disposal cycle takes place similarly with that, that the disposal robot 36 start to pick up circular bentonite blocks 12 which are on the opposite side of the vehicle 30 with turntable for conveying the disposal robot 36 with that, that the surrounding volume of disposal cask 3 is being backfilled gradually, always by one piece of bentonite filling 4, and it is finished by circular bentonite fillings 10 prepared on the last conveyance vehicle 6.
