Definitions
- the object of the invention is to improve the retention capacity of the barriers thus formed for radioactive emitters (radionuclides).
- a container according to the invention in which a capsule which contains a radioactive substance is embedded in a bed of zeolite and / or activated carbon.
- zeolite and activated carbon absorb or adsorb non-volatile or highly volatile radionuclides and thus offer the possibility of drastically reducing the radioactivity released in the event of a leak in the cap. This applies in particular to radioactive iodine, cesium and strontium. Zeoiith and activated carbon thus relieve the barrier function of the container for radioactive emitters (radionuclides).
- the bed of Zeoiith and / or activated carbon in the container also leaves enough empty space to hold free NEN noble gases, so that no high internal pressure can develop in the container.Nevertheless, the fill of zeolite and / or activated carbon has sufficient thermal conductivity to dissipate decay heat from the capsule. In addition, the filling represents an additional heat capacity in the container
- the debris especially if it contains activated carbon, also has a good moderating effect on neutrons and therefore reduces the hardness of neutron radiation that can emanate from the radioactive substance in the capsule. It can also be used to shield gamma radiation emanating from the capsule Contribute to the bulk material
- the bulk material also represents a mechanical puff for the capsule stored in the container. The bulk material is additionally protected by the bulk material from damage during transport or when handling the container. Radionuclides absorbed by the bulk material are in equilibrium due to chemical laws and thereby lose their tendency to migrate, so that the rubble reliably ensures long-term storage of the capsule.
- FIG. 1 schematically shows a cross section through a transport and / or storage container with an irradiated nuclear reactor fuel element
- FIG. 2 shows a schematic cross section of the storage container according to FIG. 1 in a repository
- This nuclear reactor fuel element 3 has capsules, especially fuel rod 4, and guide tubes 5.
- the fuel rods 4 are filled with spent nuclear fuel, for example U0 2 and / or U / Pu0 2 , which contains radionuclides.
- This nuclear fuel is located in a cladding tube of the fuel rods 4, for example made of a zirconium alloy, each of which has a stopper at the two tube ends Zirconium alloy is closed. These zirconium alloy plugs are welded gas-tight to the cladding tube.
- the guide tubes 5 were used to guide control rods and are open on at least one tube end. They contain no radionuclides.
- the storage container 2 is filled with a bed 6 of granules of a zeolite. This bed 6 need not be compressed, and the fuel rods 4 and inevitably the guide tubes 5 of the nuclear reactor fuel element 3 are also backfilled with it.
- the container 2 is made of steel and is gas-tightly welded to a steel plate at both ends.
- the container 2 which contains the nuclear reactor fuel element 3 with the spent fuel rods, is inserted into a bore which is located, for example, in a salt dome of a repository.
- a bore which is located, for example, in a salt dome of a repository.
- another fill 7 on the outside of the container 2 which is also granulate of a zeolite.
- the container 2 is completely embedded in this fill 7.
- Activated carbon can also be added to the beds 6 and 7 made of Zeoiith in FIGS. 1 and 2.
- Zeo ⁇ iith of type A preferably at least one of the substances MgA, CaA and SrA, is particularly suitable for the fillings 6 and 7.
- Such a type A zeolite can also be doped with silver, so that it contains radioactive iodine particularly well holds back, which possibly emerges from a leak in the cladding tube of a fuel rod 4, but is then already retained in front of the wall of the container 2, the retention effect of which is thus reinforced by the zeolite of the bed 6 in the container 2.
- Chabazite and mordenite are also well suited for zeolite fillings.
- Zeolites with the trade name "Zeolon Molecular Sieves" of the 400 Series, 500 Series, 700 Series and 900 Series, which bind Cs and Sr via ion exchange, are particularly well suited.
