Definitions
- the invention relates to a container for transport and / or storage of radioactive materials, the ⁇ - and n-emit radiation, and generate significant residual heat, consisting of a container body with shielding function ⁇ - and n-radiation and an inner liner.
- Containers that are used for the transport and / or storage of spent fuel elements must safely contain the radioactivity of the goods brought in and demonstrate in rigorous tests that this is guaranteed even in extreme accident situations. At the same time, however, they must also shield the gamma and neutron beams released during the radioactive decay reactions and dissipate the heat of decay to the outside. The shielding function must remain largely intact even after an accident, its integrity must be easily verifiable.
- Known shielding containers usually consist of a metallic base container with the required mechanical strength and the wall thickness required to shield the gamma rays, usually made of steel, and an outer shell made of neutron shielding material, mostly with organic substances high hydrogen content or in the form of a water jacket.
- a disadvantage of these constructions is that even slight collisions of the container, as can also occur during routine operation, can damage the neutron shielding and afterwards require extensive repair of the entire container. In the event of a serious accident, characterized by high impact forces and exposure to fire, this neutron shielding can fail completely and the dose rate in the vicinity of the container can increase.
- DE-B2-2 040 348 also describes a container in which the neutron shield is arranged in the base body under the outer skin.
- a container is also known from DE-A-2 019 446, in which neutron shielding material is arranged in the y absorption layer. Both container designs have the disadvantage that the neutron shielding layer is not freely accessible and cannot be inspected and, if necessary, repaired after an accident. Even in the event of a fire, this neutron shielding material is endangered and can easily be destroyed or ineffective.
- a container for the transport and / or storage of radioactive substances, in particular for irradiated nuclear fuel elements and highly active waste consisting of a base body with a shielding function for ⁇ and n radiation and an inner lining made of corrosion-resistant Material which has a further n-shield that is resistant to the effects of external accidents, in order to maintain sufficient shielding effect in the event of loss or damage to the outer n-shield.
- this additional shielding should not hinder the dissipation of the decay heat from the interior of the container.
- the n-shield should be easily accessible and easy to repair.
- n-shield in the form of a graphite-based material is additionally arranged between the inner lining and the base body.
- the inventive position of the additional n-shield within the solid base body ensures the best possible protection against mechanical and thermal damage, the shield is easily accessible, inspectable and repairable.
- the use of graphite according to the invention provides additional n-shielding and at the same time fulfills the requirement of good thermal conductivity. Furthermore, there is excellent resistance to elevated temperatures, such as those which occur during normal operation of the container and in particular when exposed to an accident fire.
- the moderating properties of graphite have the additional advantage that neutron activation of the container body is largely prevented.
- the n-shielding layers on the outside of the base body and the inner n-shielding according to the invention can be dimensioned such that, depending on the requirements, the inner or outer shielding layer makes the predominant contribution to shielding against neutron beams under normal operating conditions.
- I and 111 illustrate the invention in more detail schematically and by way of example.
- the transport and / or storage container consists of a base body 1, for example made of steel, on which cooling fins 2 and an outer n-shield 3 are arranged in a manner known per se.
- the interior 4 of the container for receiving the radioactive material is formed by the inner lining 5 made of corrosion-resistant material, for example stainless steel, and a shielding cover 6, which also carries n-shielding material 3 on its outside.
- the cover zone is protected against mechanical and thermal influences by a protective hood 7.
- n-shielding layer 8 made of a graphite-based material as a further neutron shield orderly.
- This graphite-based shielding layer 8 preferably consists of a mixture of graphite powder and a hardening binder, such as, for example, water glass or, above all, a casting resin.
- This mixture can either be introduced as such into the annular gap between the base body 1 and the inner lining 5 and hardened, or it can advantageously be prefabricated graphite moldings 9, z. B. in the manner of composite plasters that are adapted to the gap dimensions can be used. These shaped pieces can also be covered with a metallic jacket 10, preferably made of neutron-absorbing material. It is also possible to press a stampable graphite mass into the annular gap.
- the function of the inner lining 5 can be taken over in a particularly advantageous manner by the metallic shells 10 which surround the graphite shaped pieces 9.
- the separate inner lining 5 can then be omitted partially or completely.
- the GraphicsGro t formstük- ke 9 are particularly low attached to the inside of the base body 1, for example by guide rails 12.
- the shielding layer 8 can be easily adapted to the respective requirements by changing graphite moldings 9 of different thicknesses.
