Description of the Related Art A container for transporting and storing radioactive materials generally has a base body and a sealed cover, and further includes a connection part, and after loading, a desired container is placed in the inner chamber of the container through the connection part. It is possible to adjust the conditions, in particular the type of filling gas and the pressure of the gas. For example, the loading container is filled with helium and the pressure is adjusted absolutely to 0.5 bar. This is done in order to avoid corrosion and to cause a certain pressure drop for radiation protection reasons, and also to make the helium available for leak testing of the cover seal. However, this connection may in some cases create weak points in the container and, at least in its manufacture, be very expensive.

いる。In the transport and storage container for radioactive substances known from West German Utility Model Registration No. 7930459, a cover is fixed by screws via a sealing ring on its base body. Furthermore, an operating connection and a guide channel are arranged in this cover, which guide channel is either partially embedded in the container or connected to the chamber in the container below the cover. A sealing member is required in the cover to seal this guide path to the chamber in the container, and the blocking member is, for example, a valve, and the mechanical stability of the cover is increased due to the space requirement. Will be weakened. The guideway embedded in the container wall is within the transition range between the cover and the container wall,
It is sealed by an annular seal surrounding a cylindrical hole.

It is also possible to allow the gas load in the container inner chamber without requiring a shielding member that takes up space.

されていることによつて解決された。The means according to the invention for solving the above-mentioned problems is based on the one in which the guideway through said cover reaches the annular area between both seal rings and is located on the inside. Has a smaller diameter than the outer sealing ring, and the cross-sectional difference between the two sealing rings is properly selected according to the elastic properties of the sealing material, so that This is solved by the fact that when the cover is mounted, only the outer sealing ring is first compressed tightly and the inner sealing ring is formed so that it is not yet contacted by the cover or the base body.

ている。Example The illustrated container comprises a base body 1 and a cover 2. By these both parts, the container inner chamber 6 containing the radioactive substance is surrounded. The cover 2 is fixed to the base body 1 by screws 7. Two concentric seal rings 3 and 4 are provided for sealing the cover 2 with respect to the base body 1. At this time, the seal rings 4 located inside are arranged.
Has a smaller cross-section than the outer seal ring 3. Within the range of both seal rings 3 and 4, the respective support surfaces of the base body 1 and the cover 2 are formed parallel to each other.
両方のシールリング３，４の間のスペースに案内路５が

装置への接続が形成されている。A guideway 5 is connected to the space between both seal rings 3, 4. Via this guideway 5, connections are made to different devices such as a vacuum pump, an inert gas supply mechanism or a leak tester.

ことも可能である。After the container has been loaded, for example in a shielded cell, both concentric sealing rings 3, 4 are attached and the cover 2 is placed. It is also possible to dispose the seal rings 3 and 4 in front of the cover 2 and mount them together with the cover on the base body 1.

ー内にねじ入れることも適切に可能である。When the cover 2 is installed, care must be taken that the outer sealing ring 3 already seals, whereas the inner sealing ring 4 is initially not yet loaded and releases the gear for gas flow. There are two possibilities for this, depending on the elastic properties of the cover 2 and the outer seal ring 3 to be mounted. In the case of the light cover 2, after the cover is attached, the cover screw 7 is tightened until a predetermined distance is formed between the cover 2 and the base body 1 in advance. This distance is adjusted, for example, by a gauge.
On the contrary, in the case of a heavy cover, care must be taken not to compress both sealing rings 3, 4 at the same time due to their own weight. It is also possible to arrange several pull-up screws in the cover 2 in a known manner and screw them into the cover before mounting the cover.

The container inner chamber 6 is evacuated by means of, for example, a vacuum pump. The desired gas, which may be pure helium or another inert gas mixed with helium for performing a leak test, is then introduced. Then, in the next stage, the inner seal ring 4 is also compressed, for which purpose the respective screws 7 are finally tightened until the base body 1 and the cover 2 come into contact.

中に各シールリング３，４の間の中間室内に残されたヘ
リウム混合ガスが最初に吸出されなければならない。Thereby, the container interior 6 is sealed against the surroundings so that the container can be transported and stored with its contents.
Furthermore, there remains the problem of inspecting the sealability of the inner seal ring 4. For this purpose, the gas is drawn off in a known manner via the guide line 5 and the helium from the chamber inside is analyzed. Of course, at this time, the helium gas mixture left in the intermediate chamber between the seal rings 3, 4 during the supply flow into the container must first be sucked out.
各シールリングの材料としては金属又はプラスチック又
は両素材の混合体が用いられ得る。長期間の中間貯蔵の
ための容器の場合は有利には金属製シールが用いられ
る。The material of each seal ring may be metal, plastic, or a mixture of both materials. In the case of containers for long-term intermediate storage, metal seals are preferably used.

囲内に保つために、有利には外側のシールリング３のた
めに比較的に軟質の材料を選び、即ち内側のシールリン
グ４よりも小さめの弾性係数を有するシール体を用いる
とよい。In order to keep the required crimping force for both sealing rings 3, 4 within limits, it is advantageous to choose a relatively soft material for the outer sealing ring 3, i.e. over the inner sealing ring 4. It is preferable to use a seal body having a small elastic coefficient.
容器の積載解除時には容器内室６から試料ガスが抜出さ
れ、容器内室６と周囲との間で制御された圧力補償が行
なわれる。When the container is unloaded, the sample gas is extracted from the container inner chamber 6, and the pressure compensation between the container inner chamber 6 and the surroundings is controlled.
このために案内路５がガス捕集器又は分析器と排気装置

容器内室６への接続が形成される。For this purpose, the guideway 5 is connected to a gas collector or analyzer and an exhaust system. Subsequently, the cover 2 is lifted until the engagement with the inner seal ring 4 is released. This forms a connection to the chamber 6 inside the container.
