Definitions
- the present invention relates to a container for the transport and final storage of nuclear fuel rods.
- Repository containers made of titanium, tungsten, nickel or similar metals are known, but these metals are not sufficiently available and are very expensive to manufacture.
- the aim of the invention is therefore to create a container for the transport and final storage of nuclear reactor fuel rods which is inexpensive to manufacture and which has an excellent shielding effect against radioactive radiation, an extremely long life and good mechanical strength.
- This goal is achieved with a container which is characterized by at least one shielding jacket made of cast bronze, preferably CuPb15Sn, for covering the fuel rods and at least one further shielding jacket made of sintered magnesite bricks.
- Cast bronze is a much cheaper starting material compared to the metals mentioned. Excavations have shown that this metal has survived for around 4000 years without any damage and without material fatigue. It provides excellent shielding against the residual radiation emerging from the fuel rods.
- the sintered magnesite stones have excellent mechanical strength over a long period of time and are resistant to high temperatures, so that a possible temperature development inside the container can be kept under control. In addition, the sintered magnesite stones also contribute to a good shielding of the radioactive radiation. It should be noted that any type of concrete coating has been deliberately avoided, because over the course of decades, concrete becomes brittle and therefore porous, so that shielding can no longer be guaranteed. In contrast, the shielding effect is retained over a long time in the solution according to the invention.
- the container is provided with an outer casing made of stainless steel. This increases the long-term corrosion resistance of the container.
- the container comprises an outer casing 1, seen from the outside inwards Stainless steel, an outer bronze cast jacket 2, a jacket 3 made of sintered magnesite stones and an inner bronze cast jacket 4.
- CuPb15Sn in particular, has proven to be a suitable bronze casting alloy.
- Atomic fuel rods 5 are stored inside the container.
- Fig. 2 shows a further embodiment of the container according to the invention with a sequence - seen from the outside inwards - of the outer bronze cast jacket 2, the outer magnesite brick jacket 3, the inner bronze cast jacket 4 and the inner magnesite brick jacket 3 '.
- Atomic fuel rods 5 are stored inside the container.
- the container has a cylindrical shape and is equipped with a closure lid 10, which can also have several layers of cast bronze and / or shaped magnesite stones. Magnets 11 are embedded in the bottom 12 and in the lid 10 of the container.
- the shape of the container and the number and sequence of the shielding jackets can be modified as desired within the scope of the invention.
