Definitions

  • the invention relates to a method for handling radioactive waste that occurs in control areas of nuclear facilities.
  • radioactive waste When operating nuclear facilities, radioactive waste is generated in a wide variety, e.g. B. paper, wood, textiles, plastic, foils, rubber, glass and rock wool, rubble, glass, workpieces, tools, components, metallic scrap, cables, filters, filter frames, sludges, concentrates, resins, activated carbon, waste oil, scintillator solutions, organic solvents, radioactive sources, measurement standards, medical preparations, etc. These wastes can be recycled on a case-by-case basis; in other cases, they must be disposed of as radioactive wastes.
  • the current state of the art of handling radioactive waste is set out below using the example of nuclear power plants.
  • the waste is collected at the place of origin in appropriately approved control areas or protection zones. Open containers or stands with an inserted plastic bag of approx. 80 l volume are often used for this. In a nuclear power plant, type 1300 MWe DWR block, there can be about 80 such collection points, in a reactor block, type 1300 MWe SWR, about 140 collection points are required. Depending on the amount of waste, the containers have to be emptied several times a day. In some plants, the waste is collected separately for combustible and non-combustible parts. They are transported from the collection points to an internal waste store or the associated storage space. Removal is often made difficult by the fact that the transport z. B. takes place over several floors and multiple contamination protection zones and locks are passed.
  • the transport routes can be several hundred meters.
  • the waste is then pressed into 200-1 standard roller tire barrels using power plant presses (e.g. 16 t pressing force).
  • power plant presses e.g. 16 t pressing force
  • lumpy waste is broken down to barrel size beforehand and, if possible, also pre-compressed.
  • Some of the combustible waste is specially packaged for incineration in external incinerators and placed in 200-1 drums.
  • the waste in the 200-liter drums is then temporarily stored in internal waste storage facilities, which are also located in control areas, decontaminated if necessary and transferred from the control areas to a transport staging area.
  • Non-combustible wastes which are in sheet metal containers, are pre-pressed, pressed together with the sheet metal containers into tablet-like compacts by means of a high-pressure press and in turn placed in 200-liter barrels, which are temporarily or temporarily stored.
  • the disadvantage of the known methods is that the collection, transport, treatment and storage of the waste is very cumbersome, technically and in terms of personnel, hinders other processes, entails contamination spreading, the risk of accidents and fire and complies with the acceptance specifications of external treatment facilities , which can also result in economic disadvantages.
  • the invention was therefore based on the object of providing a method for handling radioactive waste which accumulates in control areas of nuclear facilities, which eliminates the disadvantages described, unifies handling in nuclear and downstream facilities, is safer, clearer and more economical, and is more environmentally friendly .
  • the object was achieved according to the invention in that the radioactive wastes occurring in the numerous control areas with relatively high radiocative radiation and a considerable risk of radioactive contamination are initially collected there in small containers of different geometry that are not particularly shielded, the small containers then, depending on the inventory, manually or remotely contained in several small containers , shielded, leakproof, suitably tested, dockable to nuclear facilities and suitable for intermediate storage in storage spaces, stackable, mobile reusable containers of uniform geometry, the reusable containers are temporarily parked in a few control areas with low radioactive radiation and a low risk of contamination until they are finally filled , the reusable containers after the intended final filling in due time to not particularly shielded, cont Ainer-like large containers are transported to locations free of control areas within the nuclear site and a large number of reusable containers are stacked tightly in the container-like reusable large containers, and depending on the inventory, the reusable large containers are transported to waste conditioning or incineration plants or to external interim storage facilities.
  • nuclear facility is also intended to include those facilities in which radioactive waste is generated, such as occasionally in hospitals, in external collection points and in industrial plants in which radioactive work is carried out.
  • uniform radioactive waste is filled into corresponding small containers and separately into reusable containers.
  • radioactive waste is generated in the numerous radioactive control areas (A) with corresponding radioactive radiation and a high risk of contamination.
  • These control areas (laboratories, workshops, decontamination operations, application technology center, personnel locks etc.) may be located in different buildings and here again in several building floors.
  • the radioactive waste is collected in small containers in the numerous control areas (A), some of which can be considerably spaced apart.
  • the small containers can be plastic sacks, sheet metal drums, roller hoop drums, crumple drums or other suitable smaller containers.
  • control areas (A) at favorable locations other control areas (B) with low radioactive radiation and a low risk of radioactive contamination are set up in storage spaces in which reusable containers are stationed.
  • the reusable containers are shielded, either by their own material, e.g. B. steel, or as required by additional shielding materials. They are provided with closable openings directly, can be docked to nuclear facilities such as locks, are mobile and comply with the normal test requirements for intermediate storage in a storage space and transport.
  • the reusable containers are designed in a uniform geometry, for example cubic, and constructed to be stackable. Each reusable container can hold several small containers.
  • a z. B. cube-shaped reusable container made of steel or aluminum sheet with an edge length of 1 m and decontamination-friendly stiffened surface, equipped u. a. with filler openings, emptying flap and front door, holds up to 1500 kg of radioactive waste.
  • the reusable containers are brought from the few control areas (B) to the numerous control areas (A) or to the assigned groups of control areas (A). This can be done manually or remotely. Roller conveyors, elevators or crane systems have proven their worth. In many cases, the use of uniformly designed means of transport is particularly advantageous because of type acceptance, rational production, control and maintenance. Carriers or carriages have proven particularly useful because they u. a. can be easily coupled together.
  • the control areas (A) the reusable container is filled with waste-filled small containers. In some cases, the reusable container can be docked for filling at nuclear facilities such as cells, locks or boxes, in which small containers with collected waste are located. This ensures safe, environmentally friendly filling of the reusable container without the risk of contamination or incorporation.
  • the current filling frequency as well as the transport route of the reusable container can be coordinated with the activities in the numerous control areas (A) such as production, decommissioning, laboratory tests etc. in such a way that none of these activities are hindered.
  • A control areas
  • the reusable containers are transported back to the few control areas (B) and remain there until they are filled as intended.
  • the filled reusable containers which are clean on the outside, are transported to large, non-shielded container-like reusable containers at locations (C) within the nuclear site that are free of control areas and are only monitored.
  • a large number of reusable containers are stacked tightly in the reusable large containers.
  • a reusable large container such. B. so-called EURO standard containers, capacity approx. 15-60 m 3 , can be used, which, depending on the size, can accommodate up to 48 cube-shaped reusable containers, edge length 1 m and loading of the reusable large container optimally coordinated.
  • the reusable large containers After loading, the reusable large containers are ready for transport to waste conditioning plants, incineration plants or to external interim storage facilities.
  • the orderly unloading of the reusable large containers and the allocation of the reusable containers are carried out according to the further treatment. Again, the corresponding process advantages according to the invention can be used if the infrastructure in the waste treatment plants is adapted according to the invention.
  • Uniform radioactive waste e.g. B. intended for incineration waste or metallic scrap for final storage, separately filled in reusable containers. This reduces the need for sorting and safety, and the considerable acceptance specifications for external treatment systems are met more economically.
  • the method according to the invention surprisingly simplifies the handling and organization of radioactive waste quantities, it is easy to use, safety and maintenance-friendly, therefore reduces the high costs to date, makes the radioactive waste quantity flow manageable in all respects and standardizes the movement of waste quantities between the waste producers, the waste handlers, the interim storage facilities and, if applicable, the final storage facilities according to the modular system zip, also according to common rules and instructions.
