Description
Technical field
The present invention relates to a kind of fuel rod storage, the particularly combustion for fuel rod, the fuel rod for being preferred for damage
Charge bar storage.
Background technology
In principle it is known that by the fuel element of after-flame in order to deposit and/or transport and height can mechanically be born by loading
In the container of load.Such shipping container and/or storing containers are with brand nameOr
Know.During nuclear power station is run, it may occur however that the situation that fuel element is damaged.Particularly damaged because can not possibly clearly assess
Fuel element mechanical property, it is important that the fuel element of damage, which is fitted into shipping container and/or storing containers,.Damage
Fuel element in reactor remove after be stored in decay pond in, wherein, during storage, water possibly into fuel member
In part or in the sleeve pipe of entrance encirclement nuclear fuel.Because depositing this in actual known storing containers and/or shipping container
During sample, damage fuel element, water may flow out from the fuel element of damage, so existing following dangerous, i.e. transport appearance
The material that device/storing containers are formed by the water that is flowed out from fuel element and/or in the range of residual radioactivity is due to corrosion
Damage.A kind of fuel rod storage for example as known to the A1 of DE 10 2,005 043 857, the fuel rod storage has multiple use
In the receiving pipe of the fuel rod of damage.It is known that for ensuing storage, by the way that each of fuel rod storage is accommodated
Pipe vacuumizes to dry the fuel rod of damage.After drying, it is necessary to close fuel rod storage, metal sealing is provided with for this
Part, the metal seal is arranged between the sealing surface of the sealing surface of storage side and lid side.In order to ensure by actual known
The sealing of fuel rod storage, cover plate must be compressed with predetermined, uniform pressure to seal.However, it is known that
During prolonged storage, relaxation effect may occur in the bolt of pretension, so as to cannot ensure the envelope to fuel rod storage
The sealing closed.In addition, in the fuel rod storage known to actual, the fixation to the receiving pipe of the fuel rod for damage
It is important, because the receiving pipe is regularly welded on the end plug of its bottom side with the bottom plate of fuel rod storage.In fuel rod
Storage is by during high mechanical load or when accommodating pipe due to hot length change, and weld seam is consumingly loaded, thus welds
Seam may be damaged.
The content of the invention
Therefore, technical problem of the invention is, provides a kind of fuel rod storage, the protrusion of the fuel rod storage it
It is in, high mechanical stability, reliable sealing, simple structure, high fail safe and to a large amount of different damages
The flexible adaptability of bad fuel rod.
In order to solve the technical problem, present invention illustrates a kind of fuel rod storage, particularly for fuel rod, preferably
For the fuel rod storage of the fuel rod of damage, wherein, the fuel rod storage is configured to the fuel rod storage of preferred one
Device is hidden, the fuel rod storage has the inner chamber that storage bottom, storage shell and receptacle lid are surrounded, wherein, the storage
Device lid has the receptacle lid opening (cover gab) that can be closed using closure elements, wherein, it is provided with least in the inner chamber
One is used for the receiving pipe of fuel rod, and end upper fluid of the receiving pipe in storage bottom side is sealed shut, and the envelope
Closing element can be fitted into, suitably be screwed into cover gab.
The fuel rod taken out from fuel element can be fitted into the receiving pipe for fuel rod in principle.It is preferred that
It is that accommodating pipe to one only arranges a fuel rod.The preferred specific fuel rod of fuel rod.Specific fuel rod
(Sonderbrennstab) it is, for example, nuclear fuel that is having radiated or not radiating, the form of the nuclear fuel is to be preferred from pressure
Undamaged or damage fuel rod, fuel rod section or the loose fuel of power water reactor or boiling water reactor.It is special
Different fuel rod can be surrounded or can be placed in operation sleeve pipe by envelope.It is made up of shell and/or operation sleeve pipe
Enclosure body preferably by stainless steel and/or zirconium alloy into.According to a kind of form of implementation, the specific fuel rod is the fuel damaged
Rod, the fuel rod be, for example, deformation or fracture.Within the scope of the invention, the specific fuel rod is prior damages
