Definitions
- the container body is therefore made of steel or cast iron to ensure the mechanical stability of the container.
- GGG 40 spheroidal graphite cast iron
- the invention has for its object to provide a container of the type described above, which has an outer corrosion protection layer, which can be manufactured with less technical effort and lower costs.
- the object is achieved by the features mentioned in claim 1.
- the thick-walled container body made of spherulitic cast iron is cast in a casting mold with the melt of the high-alloyed austenitic nodular cast iron.
- the surface of the container body is melted and this creates a good connection between the two layers of the container.
- the good connection between the two layers of the container is also promoted in that the structure of the outer layer is similar to the structure of the container body made of spherulitic cast iron.
- the outer layer of high-alloy austenitic nodular cast iron is characterized by good heat and corrosion resistance with good processing and casting properties.
- the main advantage of this material is its weldability.
- a cold-weldable material is understood to mean a material that can be welded without subsequent heat treatment. With such materials, no significant stresses or structural changes occur during welding, which have to be compensated for by an additional subsequent heat treatment.
- the container can be cold-welded via a closure lid which is similar in structure to the material of the outer layer. Subsequent heat treatment of the container body is not necessary.
- the outer cast layer of the container can have a much greater thickness than the Zircaloy cover plated on a container base body. Due to the possible thickness and the good connection between the layers, it is possible to use the container not only for storage but also for transporting the irradiated fuel elements between the nuclear power plant and the long-term storage facility.
- the invention has the further advantage of achieving a corrosion protection layer that is resistant to external influences. It is resistant to mechanical influences such as impact, friction, shear forces and fire. Furthermore, the invention enables good reproducibility of the container structure.
- Such a material is GGG NiCr 20.2 (trade name: Ni-Resist).
- the container receiving the fuel elements not shown here has a thick-walled container body 1 made of spherulitic cast iron.
- This container base body 1 is cylindrical and open at one end. This forms a receiving opening 2 for loading with the fuel elements, not shown here.
- the container base body 1 is provided on the outside with a cast layer 3 made of high-alloy austenitic nodular cast iron.
- the open end of the container is closed by a cover 4, which consists of the same material as the outer layer 3 of the container body 1 and is tightly welded to this outer layer 3.
- a second closure cap 5 is arranged in the container and is connected to the container base body 1 consisting of spheroidal cast iron.
- the container body 1 has been used in the manufacturing process for the outer layer 3 as a molded part in the mold. After the high-alloy austenitic nodular cast iron has been poured in, the surface joins surface of the container body 1 by melting its surface with the outer layer 3. The two layers 1 and 3 of the container are thus firmly connected. Since the sealing cap 4 is made of the same material as the outer layer 3 and can therefore also be cold-welded, subsequent heat treatment of the container after welding is not necessary.
