Abstract
The utility model relates to a special storage-transport vessel for nuclear waste, which is provided with a steel casing, a polyethylene inner liner and a primary shielding layer between the inner liner and the casing, wherein the primary shielding layer comprises a lead shielding layer and a borax shielding layer. The utility model adopts a compound shielding layer of steel, lead, polyethylene and borax, wherein the lead shielding layer mainly shields the gamma and beta-ray in the nuclear waste, while the borax and polyethylene shielding layers shield the neutron. Each shielding layer exerts own shielding advantage so as to decrease the gross thickness of the vessel shielding layer. On the condition that the dimension of the existing storage-transport vessel for nuclear waste is not changed, the storage capacity can be increased by five times, which reduces the carrying cost of the nuclear waste.
Description
Technical field
The utility model relates to a kind of storage-transport vessel, particularly a kind of storage-transport vessel that is exclusively used in nuke rubbish.
Background technology
How the development of nuclear industry particularly in the nuclear power station fast development, has also brought the worldwide technological puzzle of process nuclear waste material.General in the world processing mode is to be sent to special storage vault after the packing to store at present, promptly nuke rubbish will be contained in the storage-transport vessel of a special use, is sent to national ad hoc nuke rubbish storehouse permanent storage then.At present, existing nuclear waste material storing and transporting container is the very thick concrete of filling between the inside and outside shell of steel, and the thickness of concrete shielding is the diameter of liner no better than, that is, the efficient loading diameter of storage-transport vessel only accounts for about 1/3rd of container actual diameter.This use concrete is made the nuclear waste material storing and transporting container of screen layer, and not only useful capacity is little, and the storage space that takies is big, and also there are many problems in its safety with keeping.For example concrete shielding has the possibility of cracking, in case concrete shielding cracking or shell of tank corrosion cause karyomerite to pollute the life security that jeopardizes people around will giving.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned weak point of the prior art, provides a kind of useful capacity big, and safe and reliable nuclear waste material storing and transporting container.
The technical solution that realizes above-mentioned purpose is: the nuclear waste material storing and transporting container that is provided has a steel casing, liner and the primary shield between liner and shell; Improvements of the present utility model are that said primary shield comprises one deck lead shield layer and one deck borax screen layer at least.
Above-mentioned said liner is polyethylene liner preferably, and shell preferably adopts stainless steel casing.
Compare with existing nuclear waste material storing and transporting container, the utility model has adopted steel, plumbous, borax and tygon composite shielding layer, wherein the lead shield layer mainly shields γ in the nuke rubbish and β ray, borax, the tygon screen layer mainly shields neutron, the advantage of each screen layer performance self, compound action reaches optimum shield effectiveness, thereby can reduce the gross thickness of container shield layer, under the prerequisite that does not change existing nuclear waste material storing and transporting container physical dimension, memory capacity can increase by 500, and the increase of memory capacity has also reduced the carrying cost of nuke rubbish.In addition, compare with available coagulation soil screen layer, the security of composite shielding layer of the present utility model also improves significantly.
