Definitions
- the present invention relates to a container for the transport and final storage of atomic 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 atomic 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 CuPbl5Sn, for covering the fuel rods and at least one additional shielding jacket made of sintered magnetic stones.
- Cast bronze is a much cheaper starting material compared to the metals mentioned. Excavations have shown that this metal has survived for about 4000 years without any damage and without material fatigue. It offers 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 also be kept under control. In addition, the sintered magnesite stones also contribute to good shielding of the radioactive radiation. It should be noted that any type of concrete sheathing has been deliberately dispensed with, because concrete has become brittle and therefore porous over the course of decades, so that shielding is no longer guaranteed. In contrast to this, 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.
- Fig. 1 shows a cross section through a first embodiment
- FIG. 2 shows a longitudinal section through a second embodiment.
- the container comprises an outer casing 1, seen from the outside inwards _ _
- CuPbl5Sn has proven to be a particularly suitable bronze casting alloy. Inside the container, atomic fuel rods 5 are kept on.
- Fig. 2 shows a further embodiment of the container according to the Invention with a sequence - seen from the outside inwards - from the outer bronze cast shell 2, the outer magnesite mold stone shell 3, the inner bronze cast shell 4 and the inner magnesite shaped stone shell 3 '.
- Atomic fuel rods 5 are stored inside the container.
- the container has a cylindrical shape and is equipped with a closing cover 10, which may also have several layers of bronze and / or magnesite stones. Magnets 11 are embedded in the bottom 1 and in the lid 10 of the container.
- the shape of the container and the number and sequence of the shielding sheaths can be arbitrarily changed within the scope of the invention.
