Definitions
- the present invention relates to a transport and / or storage container for radioactive substances, in particular for irradiated fuel elements from nuclear reactors, consisting essentially of a container body with a shielding function for gamma radiation, neutron shielding and cooling fins on the surface of the container body for heat dissipation to the environment .
- Transport / storage containers for radioactive materials must also withstand severe 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.
- cooling fins When falling on the surface provided with cooling fins, it must be accepted that the cooling fins in the area of the point of impact will be damaged. In previously known containers with welded or cast-on cooling fins, there is the disadvantage that the cooling fins may break off a crack propagation into the container body representing the tight enclosure of the radioactive substance takes place.
- the object was achieved in that webs are attached to the surface of the container body transversely to the direction of extension of the cooling fins.
- 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 are in the axial direction of extension of the cooling fins run around, but run axially with all-round cooling fins. Casting the cooling fins (2) and webs (3) onto the container body (1) has proven to be particularly advantageous.
- the transverse webs (3) have the result that the inevitable breakage of the cooling fins (2) does not occur on impact at the fin base (6), 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. As theoretical calculations and experiments have shown, it is particularly advantageous to dimension the webs (3) such 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 dependent on Aus Laying and material also very effective.
- 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 on the surface of the container body in the axial direction.
- the cooling fins have a height of approx. 240 mm.
