Definitions
- the present invention relates to a transport and / or storage container for radioactive materials, in particular for irradiated fuel elements from nuclear reactors, consisting of a container body with a gamma-ray shielding function, neutron shielding and axially or radially extending cooling fins on the surface of the container body for heat dissipation to the environment .
- Transport and / or storage containers for radioactive materials must also withstand serious accidents in accordance with traffic regulations, whereby the accidents when testing the model include are simulated by falling from a height of 9 m onto an unyielding surface. After such a load, the container must remain tight and there must be no significant weakening.
- DE-A-2221 610 describes a container for radioactive substances which consists of an inner container with a gamma-ray shielding function and an outer container which has axial and radial ribs to increase the mechanical strength. These fins do not contribute to heat radiation and therefore cannot prevent the cooling fins of the inner container from breaking off and damage to the container body in the event of an accident.
- the object was achieved according to the invention in that webs are arranged on the surface of the container body transversely to the direction of extension of the cooling fins, the height of which is a maximum of 2/3 of the height of the cooling fins and that the webs are arranged at a distance from one another which is a maximum of 10 times the web height is.
- cooling fins have notches in the region of the transverse webs, the maximum depth of the notches forming the upper limit of the webs. Furthermore, it is advantageous if cooling fins and webs are cast together on the container body and the space formed by cooling fins and webs is filled with neutron shielding material.
- a transport and storage container consisting of a container body (1) and other parts and equipment known per se, has cooling fins (2) on its surface.
- Crosspieces (3) are attached transversely to the direction of extension of the cooling fins (2), which run all around in the axial direction of extension of the cooling fins, but run axially in the case of all-round cooling fins.
- the joint casting of the cooling fins (2) and webs (3) onto the container body (1) has proven to be particularly favorable.
- the result of the transverse webs (3) is that the unavoidable breakage of the cooling fins (2) does not occur on the fin base (6) on impact, where there is a risk of crack expansion in the container body (1), but at a certain distance from the fin base.
- the safe distance of the crack from the container body (1) is guaranteed by the selection of the appropriate web heights and the corresponding web spacing.
- the webs (3) should be dimensioned so that the web height is a maximum of 2/3 of the height of the cooling fins (2) and the web spacing is a maximum of 10 times the web height.
- a particularly advantageous embodiment consists in providing notches (4) in the cooling fins (2) in the region of the webs (3), which ensure the targeted formation of cracks even more reliably without penetration into the container body (1) by the formation of cracks on the webs (3) the predetermined distance from each other is limited.
- the maximum depth of the notches (4) is reached at the upper limit (5) of the webs (3). Shallow depths of the notches (4) are also very effective depending on the design and material.
- the notches can be molded on or, if necessary, worked in later.
- a cast container for irradiated fuel assemblies from pressurized water reactors with cast-on surrounding webs, spacing from each other approx. 440 mm, web height approx. 70 mm, has cooling fins which are arranged in the axial direction on the surface of the container body.
- the cooling fins were approximately 240 mm high. In the area of the transverse webs are in the Cooling fins notches with a notch depth of approx. 95 mm.
