容器本体にまで亀裂が拡がらない。 The cooling ribs of the container in the present invention have the function of discharging heat within the container and buffering impact in the event of an accident. Furthermore, the notches provided in the web serve to ensure that, in the event of an accidental load, the cooling ribs crack at the intended rupture point, so that the cracks do not propagate into the container body.
以下に実施例に基づき本発明を説明する。 The present invention will be explained below based on Examples.

１に鋳造されているととりわけ有利である。 A transport and storage container consisting of a container body 1, known further parts and fittings has cooling ribs 2 on its surface. A web 3 is attached perpendicularly to a cooling rib 2 extending along the container axis. It is particularly advantageous if the cooling ribs 2 and the webs 3 are cast together on the container body 1.

決められている。 By providing the web 3, the inevitable breakage of the cooling rib 2 in the event of a collision does not occur at the rib foot 6, where there is a risk of the crack spreading to the container body 1; They begin to appear at intervals. Selection of a suitable web height and suitable web spacing ensures that cracks occur at a safe distance from the container body. As shown by theoretical calculations and experiments, it is especially advantageous for the webs 3 to have a web height that is at most 2/3 of the height of the cooling rib 2 and a web spacing that is at most 10 times the web height. It is determined that

ら加工することもできる。 In a particularly advantageous embodiment, the cooling rib 2 is provided with a cutout 4 in the web 3, which cutout ensures the formation of a crack at the intended rupture point without penetrating into the container body 1. This acts in such a way that the crack does not extend beyond the distance provided by the web 3. The maximum depth of the cutout 4 reaches the upper limiting edge 5 of the web 3. The relatively small depth of the cutout 4 is likewise very advantageous in terms of design and materials. The recesses can be integrally formed at the same time as the cooling ribs are formed, or they can optionally be machined later.

によつて確実に避けられる。 A cast vessel for irradiated fuel elements from a pressurized water reactor is provided with cast annular webs with a mutual spacing of approximately 440 mm and a height of approximately 70 mm and arranged axially on the vessel body surface. It has cooling ribs. The cooling ribs have a height of approximately 240mm. The cooling rib is provided with a notch in the web extending at right angles, the maximum depth of the notch reaching the upper limiting edge of the web. Such design data ensures that cracks in the container body are avoided by causing damage to the cooling ribs.
