Definitions

  • the invention consists of a method according to claim 1 and an apparatus for performing this method.
  • the solids which are primarily intended to mean ion exchange resins, can only have a granular structure, because they are to be transported by pumps and, if necessary, stirred to mix with the binder.
  • the solids are to be poured into landfill containers in the nuclear power plant, into which the binder is then poured through a lost cover.
  • the invention is based on the task of simplifying the final storage for filter cartridges or filter cartridge inserts, which are known to have to be handled with special grippers.
  • filter cartridges or filter cartridge inserts are prepared for final storage in such a way that they are dried in the waste container provided for this purpose, for example a so-called standard barrel, and then poured with hot bitumen. The pouring process takes 30 minutes or more. In this way, cavities are avoided, which could otherwise arise due to the shrinking of the bitumen. The loading of the waste container is left open.
  • a special transport process is spared because the contaminated filter cartridges are brought into the waste container with the transport means that are necessary for their operation.
  • the final storage capacity is then produced by adding the binder.
  • This is preferably concrete or cement milk, which can be transported and filled without special equipment. All that is required is a transport vessel, optionally provided with mixing devices, for example in the manner of a cement mixer, as used on construction sites, with a downstream thick matter pump. This allows the binder to be filled through the lid. After filling, which results in a shield, the lid is removed and replaced for the waste container by a closure that can be disposed of. The shielding container remains open until it is used again, in which it again receives a waste container.
  • the waste container is preferably connected to an exhaust system during the filling process via a coupling point provided on the cover. This can prevent radioactivity from spreading with the gas that is produced and escapes during filling.
  • the filling level can be checked during the filling process with the aid of an opening through the lid. This can be done by observation so that one window is sufficient. But you can also use probes or dipsticks to determine the filling distance.
  • a shielding container known per se has a lid that fits onto its loading opening, that has a seal on the inside of the container for a waste container enclosed by the shielding container, and that at least on the outside of the cover a coupling point is provided for connecting an outer to a line leading through the cover.
  • the line can advantageously lead obliquely through the cover so as not to interrupt the shielding in the area of the cover. It can be angled for the same purpose.
  • Inclined is also understood to mean a shape in which the line is led helically through the cover. At the ends of the helix there can be bends that lower one towards the cover surface right exit. It is also possible for the line to comprise an exchangeable lining. This can prevent it from becoming blocked by binders during use.
  • the exemplary embodiment is filter candles 2, which are obtained, for example, in the wastewater or coolant cleaning system of a nuclear power plant, in particular a pressurized water reactor. These filter candles 2 are removed from their filter housings with grippers (not shown) as a means of transport by remote control.
  • the shielding container 1 is loaded with a waste container 3 in the form of a standardized 200 1 steel drum and moved to the operating location so that it can be loaded with the said gripper.
  • the filter candles 2 keep a certain distance from the inner wall of the waste container 3 because this is provided with a support grid 4.
  • the shielding container 1 After loading the waste container 3, the shielding container 1 is closed with a lid 6.
  • This lid also forms a seal for the waste container 3, because a soft material seal 7 lies on a container flange 8 of the waste container. It is also an essential component of a binding device for the filter candles 2.
  • the cover 6, which, like the shielding container, consists of shielding material, comprises an actually helical line 10 drawn obliquely in the figure, which has a coupling point 12 in the form of a flange connection on the top 11 of the cover 6 for the connection of a binding agent line 13.
  • a quick-action coupling with a radial seal can advantageously also be provided.
  • the line 10 leading through the cover can have an exchangeable insert 14, which is designed as a flexible plastic hose and can be cleaned well after casting or is replaced by a new one.
  • a second line 16 leads through the cover 6 in the angled shape shown in the figure. It is equipped on the top 11 of the cover with a coupling point 17, also in the form of a quick-action coupling, so that an exhaust air line 18 can be connected, which leads to an exhaust gas or exhaust air system.
  • a third line (not shown in the figure) leads through the cover 6, which is equipped with a further coupling point 20.
  • a level meter 21 can be attached there, for example a float body protruding into the waste container 3, or a dipstick or the pneumatic measuring lance subsequently described.
  • a carriage 24 is provided, which is indicated in the figure by the dashed line and which can actually be in the form of a hand truck or hand truck.
  • the carriage 24 comprises the facilities required for loading the binder in an easily transportable form.
  • the concrete slurry used as a binder with particular advantage is introduced into a feed hopper 25 which is equipped with a mixer 26.
  • the mixer is operated by a pneumatic motor 27. This is fed via a valve 28 from a pneumatic manifold 29 which can be connected via a quick coupling 30 to the compressed air network usually present in power plants.
  • the discharge opening 32 of the funnel 25 leads to a thick matter pump 33 which is driven by a second pneumatic motor 34. This is also connected to the manifold 29 via a valve 35.
  • the thick matter pump 33 conveys into a binder line 13 leading to the quick coupling 12 via a diaphragm valve 36, the diaphragm 37 of which can be actuated pneumatically.
  • a control line 38 is provided with a valve 39, the drive device 40 of which is actuated by a fluidic component 41.
  • the fluidic component 41 belongs to the fill level measuring device, which was designated as a whole as 21 above. It comprises a nozzle, not shown in the figure, which is acted upon by an air flow at reduced pressure.
  • the fluidic component 41 is connected to the manifold 29 via a pressure reducing valve 42.
  • the desired pressure of, for example, 0.1 bar can be monitored with a pressure measuring device 43.
  • the level of the binder fed into the waste container 3 is detected by the dynamic pressure which rises with the level of binder increasing. Therefore, when the desired binder height has been reached, a command can be given to the valve 39 via the fluidic component 41, so that the further supply of binder is stopped by closing the membrane valve 36.
  • the feed device for the binding agent which is designed to be transportable with the carriage 24, is easily movable, so that it, like the shielding container 1, can be brought directly to the operating site, where the filter candles 2 to be removed are produced.
  • the figure further shows that only a single energy source is required for the operation of the new binding device, namely the compressed air fed in via the quick coupling 30.
  • the actuation of the motors 27 and 34 fed therewith for the mixer 26 and the thick matter pump 33 can also be made dependent on the fill level as well as the closure of the valve 36 if this is desired. It is also conceivable to operate the level measurement and the motor and valve actuation with another energy source, for example electrically, with the control being carried out electronically. But here, too, it would be advantageous to keep the number of connecting lines small by using a single energy source.
  • the solid to be treated for final storage is only moved with the means of transport that are necessary for its operation before it is conditioned for final storage.
  • this means of transport it is brought into the waste container 3, which is located in the shielding container 1.
  • the cover 6 used as a binding device the conditioning required for final storage is carried out by filling in cement milk or concrete. After covering it and, if necessary, after the cement has hardened, the cover 6 is lifted off. Then the waste container 3 can be closed by a lid, so that the waste container is prepared for final storage.
  • Removing the cover 6 and putting on the closure, not shown, for the waste container 3 can also be carried out elsewhere. After loosening the coupling points for the lines 13 and 18 and, if necessary, dismantling the fill level measurement 21, the shielding cover 6 can be brought to the place where the closure for the waste container takes place.
