Definitions
- the invention relates to a method and a device for storing a plurality of containers which contain heat-generating contain in particular radioactive material.
- the invention is based, while Storage an optimized discharge of the permanently generated To enable heat with particularly simple means.
- the convective heat transfer to the ambient air takes place not only on the container walls, but in addition also on intermediate, heat absorbing Structures. This increases the heat dissipation without one additional support, such as forced ventilation, would be required. The heat dissipation is thus through convective removal of the radiant heat of the containers with the help additionally set up areas improved.
- the device mentioned at the outset according to the invention with at least one partition made of heat absorbing material provided so between adjacent containers is arranged that there is a convection flow on both sides of the partition builds.
- a partition made of heat absorbing Material prevents mutual transmission of heat radiation between adjacent containers. Instead of hitting an adjacent container, the Radiation absorbed by the partition, the latter has a lower temperature than the container walls. The partition heated in this way can then heat the ambient air give off, causing convective currents adjust on both sides of the partition.
- the lower area of the partition has enough free space to ensure an undisturbed inflow of air to ensure.
- the arrangement of the partition or the partitions can in can be taken in many different ways. Often it can be enough between two adjacent rows of containers one provide only one continuous partition. It is better in many cases, preferably a grid of right angles to create intersecting partitions into which the container be inserted. Each container is then against all neighboring containers are shielded from heat radiation.
- a further advantageous embodiment which is characterized in that at least some of the containers spaced from a separate partition are surrounded. So are two adjacent containers each provided with a spaced partition, so can these partitions give off heat on a total of four wall sides. This means that the total heat emission improves again can be.
- the partitions are advantageously at the bottom Provide the end with air passage openings that the afterflow of cooler medium in the lower partition area facilitate.
- the partition is preferred on both sides with essentially vertical ribs to provide. Ribs arranged in this way lead to an enlargement the thermally effective surface and improve the heat transfer again.
- the containers with essentially in the axial direction provided axial ribs. This is very special advantageous for elongated containers. So molded containers are usually used for reasons of space upright.
- the axial ribs then run vertically Direction, d. H. parallel to the flow direction of the air flowing convectively.
- the ribbing of the containers can therefore be considerable Contribution to effective heat dissipation during storage afford to.
- the ribs also enlarge the heat-emitting surface and improve the flow guidance the ambient air.
- the container can to provide them with axial ribs or radial ribs.
- Containers with axial ribs are more suitable for a standing one Storage.
- Containers with radial ribs which are used for standing storage are provided to assemble axial ribs from rib sections, which are ring-shaped in the spaces between the radial ribs to be ordered. It will, for example possible with radial ribs in the original container Store condition lying flat with radial flow if the standing direction is changed, then the rib orientation to the new flow direction of the flowing Adjust medium.
- Another development of the invention is characterized in that that the axial ribs as continuous elements are placed on the smooth container walls.
- the heat dissipation from the improves Containers by the preferably releasably attached ribs or rib segments.
- the continuous elements of the Axial ribs or the ring-shaped in the spaces between Radial ribs arranged rib sections from in the circumferential direction running clamping elements against the container walls be tense.
- Clamping elements are available in numerous forms Known in the art and allow those described above Rib sections or rib segments and the continuous rib elements particularly quick, easy and securely clamped against the container walls and if necessary to get rid of it again.
- tension can for example with tensioning straps, belts or tension wires work.
- the training also proves to be advantageous the continuous elements of the axial ribs or wreath-shaped in the spaces between the radial ribs arranged rib sections as open at both ends Hollow sections.
- the mass is massive executed ribs significantly lower, which u. a. make transportation easier.
- Figure 1 shows a bearing with several adjacent to each other arranged containers 1, which is a radioactive, heat-generating Material included. Between the containers 1 partition walls 2 are arranged such that adjacent containers 1 are shielded from each other. Each of the partitions 2 is provided with a plurality of ribs 3. The alignment the partitions 2 and the ribs 3 is normal to horizontal plane so that the surrounding heated air is on the partitions 3 can rise vertically upwards.
- FIG 2 shows several arranged adjacent to each other Storage container 1, each with one of the partitions 2 Ribs 3 are enclosed and shielded from each other by this become.
- each container 1 is of its own Partition 2 completely enclosed. This means that between two containers 1 arranged next to each other Embodiment are two partitions 3 each.
- the partitions 2 spatially from the containers 1st spaced. This means that an outgoing from the storage container 1 Heat radiation hits the partition 2. Doing so absorbs the heat radiation from the partition 2. The Partition 2 heats up and gives the heat to the flowing Exhale.
- FIG. 3 shows that the partition 2 provided with air passage openings 4 in the lower area is.
- the flow of ambient air in the annulus between the container 1 and the partition 2 by appropriate Arrows indicated.
- Figure 4 shows a partial radial section through a smooth storage container 1 with attached axial ribs 5, the are designed as continuous elements. It can be seen that the axial ribs 5 on the container facing Shaped side complementary to the container surface are. The three axial ribs 5 shown can be combined with others Axial ribs can be combined as required, so that the entire Perimeter of the container 1 or a portion thereof covered is. Instead of the previously existing smooth surface through the use of axial ribs the thermally effective Surface enlarged many times over. In particular the The embodiment of the axial ribs 5 shown in FIG. 4 as open hollow profiles with an effective outer surface and one effective inner surface has in addition to the advantage of very low mass still the advantage of bilaterally effective thermal surfaces.
- FIG. 5 shows a representation similar to that of FIG Figure 4 is a partial radial section through a ribbed Container 1 according to a further embodiment, and Figure 6 shows a corresponding axial partial section.
- the Container 1 is provided with radial ribs 6.
- the storage container 1 designed in this way can be stored vertically instead of horizontally, without the radial ribs hindering heat dissipation.
- the number of items the axial ribs, the rib sections and the rib shape in wide ranges can be varied.
- the rib elements Numerous others can be attached to the containers known fasteners can be selected. exemplary include screw connections, outer clamping rings, etc.
- the invention is applicable to the storage not only of radioactive, but generally of heat-generating materials.
