Abstract
The utility model relates to a storage and transportation container for nuclear waste, which belongs to the technical field of packaging of radioactive waste. The storage and transportation container for the nuclear waste comprises a barrel body and a close cover which are made of concrete, an annular inner clamping groove and an annular outer clamping groove are made on an upper port of the barrel body, and a metal lining is arranged on an inner surface below the inner clamping groove. Compared with the existing storage and transportation containers for the nuclear waste, due to the face that the metal lining is not arranged in the inner clamping groove of the storage and transportation container for the nuclear waste, when the close cover is clamped in the annular inner clamping groove of the barrel body, a contact face of the close cover and the inner clamping groove is made of the same material (concrete), and micro-gaps are prevented from being caused during use so as prevent radial from leaking from the close cover position.
Description
Technical field
The utility model relates to a kind of device that is used for the accumulating nuclear waste, belongs to radioactive waste encapsulation technology field.
Background technology
For low, the middle horizontal radiation property nuclear waste that produces in the nuclear power station operational process, need these nuclear wastes to be stored and transport with interim packaging system.The packaging system of existing accumulating nuclear waste generally is the billy that material mainly adopts reinforced concrete to process.For example the applicant of the utility model the Chinese patent (application number 200720038080.5) of first to file disclose a kind of in, low-level level radioactive nuclear waste storage, comprise staving, be lined with metal inner lining at the inside surface of staving; But radiation leakage takes place in the top closure place of this container easily.For this reason; The applicant of the utility model again in first to file Chinese patent (application number 200920039600.3) disclose a kind of in, low-level level radioactive nuclear waste storage; The staving of this container is processed by high performance concrete, at the staving prefabricated inside and outside draw-in groove of ring-type that has suitable for reading; But the applicant of the utility model finds that in practice still there is the problem of leaking a small amount of ray in the top closure place of this container.Therefore, need this container is further improved.
Summary of the invention
The technical matters that the utility model will solve is to propose a kind of device that is used for the accumulating nuclear waste that can overcome a small amount of ray defective of above-mentioned existing nuke rubbish storage existence leakage.
The utility model is that the technical scheme that solves the problems of the technologies described above proposition is: a kind of nuclear waste storage-transport vessel; Comprise the staving and the capping of mainly processing by concrete; The inside surface that the inner card cage and the exterior bayonet slot that is shaped on ring-type suitable for reading of said staving, said staving are positioned at below the inner card cage is lined with metal inner lining.
Like the existing nuke rubbish storage of mentioning in the above-mentioned background technology, in actual use, capping is contact with metal inner lining when snapping in the inner card cage, because the thermal expansion factor of these two kinds of materials is different, so can produces micro chink and causes a small amount of radiation leakage.
The nuclear waste storage-transport vessel of the utility model is compared above-mentioned existing nuke rubbish storage; Owing to do not establish metal inner lining in the inner card cage; In the time of in capping is stuck in staving ring-type inner card cage; The surface of contact of capping and inner card cage is same material (concrete) entirely, produces micro chink in therefore can avoiding the use of, and leaks from capping thereby stop ray.
The perfect of technique scheme is: the cross section of said inner card cage is that hypotenuse is asymmetric trapezoidal.
Description of drawings
Be described further below in conjunction with the nuclear waste storage-transport vessel of accompanying drawing the utility model.
Fig. 1 is the nuclear waste storage-transport vessel structural representation of the utility model embodiment.
Embodiment
Embodiment
The nuclear waste storage-transport vessel of present embodiment is as shown in Figure 1, comprises the staving 1 and capping 2 mainly processed by concrete, and the inner card cage 3 and exterior bayonet slot 4 that is shaped on ring-type suitable for reading at staving is positioned at the inside surface of inner card cage below 3 at staving and is lined with metal inner lining 5.
The cross section of inner card cage 3 is that hypotenuse is asymmetric trapezoidal.
The nuclear waste storage-transport vessel of the utility model is not limited to above-mentioned each embodiment, and all employings are equal to the technical scheme that replacement forms, and all drop on the protection domain of the utility model requirement.
Claims (2)
1. a nuclear waste storage-transport vessel comprises the staving and the capping of mainly being processed by concrete, and the inner card cage and the exterior bayonet slot that is shaped on ring-type suitable for reading of said staving is characterized in that: the inside surface that said staving is positioned at below the inner card cage is lined with metal inner lining.
2. according to the said nuclear waste storage-transport vessel of claim 1, it is characterized in that: the cross section of said inner card cage is that hypotenuse is asymmetric trapezoidal.
