Abstract
The utility model relates to a storage device for storing radioactive waste in the nuclear industry and the nuclear power industry, which is particularly capable of safely, effectively storing barreled radioactive waste, and the accessing is convenient. The bottom portion and the upper portion of the storage device are respectively equipped with locating steel plates, the locating steel plates are connected with steel tube members to form a well way, the upper ends of the steel tube members are equipped with a connecting sleeve, the upper portion of the connecting sleeve is equipped with a cast guiding sleeve, and the guiding sleeve is closed through a cone which is cast by cast iron and a shielding hole plug which is equipped with blocking ray steps. The friction coefficient of the well way which comprises the steel tube members is small, and the putting and removalling of a radioactive waste barrel are convenient. The guide sleeve and the hole plug are cast by the cast iron, the combined tolerance precision of the hole plug and the guide sleeve is guaranteed by the casting technique, the opening and the closing thereof are convenient through the corn structure of the well hole, thereby increasing the shielding property of the storage device, and avoiding the damage of radioactive leak and the radioactivity for operating staff.
Description
Technical field
The utility model relates to a kind of nuclear industry and nuclear power industry is used to store the radioactive waste storage device, especially can safe and effective storage barreled radioactive waste, and make things convenient for access.
Background technology
At present, storing radioactive waste bucket storage facility structure during known nuclear waste is handled and kept in is made up of cement support column, cement hoistway, cement hole plug and cement screen layer.During deposit operation, the radioactive waste bucket is hung in the cement well multilayer pile up, during transfer operation, need be with the radioactive waste bucket by hanging out in the storage well, each operation all needs to open and the sealing hole plug.But because the restriction of cement structures construction technology, the tunnel dimension error is big, and can not smooth connection between each cement components, and radioactive waste bucket card bucket easily when depositing in and take out falls barrel accident easily.Cement hole plug precision and interchangeability are poor, need contraposition during sealing, to angle with to mark, open and close difficulty, and off-period is long, and radioactive leak is big, and is unfavorable to operating personnel.
The utility model content
In order to overcome the deficiency of existing radioactive waste bucket storage well, goal of the invention of the present utility model provides a kind of radioactive waste bucket storage unit device, the radioactive ray waste storage storehouse of forming by this cell arrangement, not only hole plug opens and closes conveniently, hoistway does not block bucket, safe and reliable, each unit hole plug is interchangeable, handled easily, and be convenient to realize robotization.
The technical scheme that its technical matters that solves the utility model adopts is: storage facility bottom and top are separately installed with fixing steel plate, fixing steel plate is connected with steel tube component and forms hoistway, the steel tube component upper end is equipped with adapter sleeve, the adapter sleeve top is the orienting sleeve of shielding iron casting, and the sealing of orienting sleeve is adopted the taper of iron casting and the shielding hole plug of blocking-up ray step is arranged.The hoistway friction factor that steel tube component is formed is little, can easily putting into or taking out the radioactive waste bucket.Orienting sleeve and hole plug adopt iron casting, and its casting technique guarantees the tolerance grade that combines of hole plug and orienting sleeve, and the pyramidal structure design of hole plug opens and closes conveniently it, and has improved the shielding of storage facility.
The beneficial effects of the utility model are, the radioactive waste bucket deposit in or during withdrawing device hoistway do not block bucket, avoid the generation of barrel accident.The consistance of casting technique assurance device hole plug physical dimension.The radioactive waste temporary library that this device is formed, each storage unit hole plug can exchange, and is short to bit time, and opening and closing operations is convenient.This device shielding is good, and can realize that power-driven robot operates automatically, avoids the harm to operating personnel of radioactive leak and radioactivity.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is shielding hole plug and orienting sleeve structural representation;
Fig. 3 is put shielding hole plug and orienting sleeve structural representation in being.
Embodiment
Referring to Fig. 1, the storage facility of this radioactive waste bucket is made up of basic location-plate 1, guidepost 2, last location-plate 3, adapter sleeve 4, orienting sleeve 5 and hole plug 6.Basis location 1 is fixed on the concrete pedestal face by the civil engineering pre-embedded bolt, and basic location-plate 1 is used to support ambition post 2.Guidepost 2 connects basic location-plate 1 and last location-plate 3 component units hoistways, and the effect of guidepost 2 is immobilization of radioactive pails for used dressings 7.Several radioactive waste buckets 7 can be stored in each unit, and the unit is stored radioactive waste bucket 7 quantity and can be changed according to storage capacity.Adapter sleeve 4 is fixed between location-plate 3 tops and the orienting sleeve 5, is used for isolated location hoistway and cement screen layer.Orienting sleeve 5 is embedded in advance and forms the unit targeting port in the cement screen layer above adapter sleeve 4.Hole plug 6 is placed in the orienting sleeve, is used for the shielding of radioactive waste.When the accessing operation of radioactive waste bucket 7, hole plug needs to open and close.
Referring to Fig. 2, orienting sleeve shown in the figure and hole plug structure are used for storing, the radioactive waste of low-activity.The cast iron orienting sleeve is big circular conical surface 8 to wall top, and the bottom is the roundlet conical surface, and the middle part is shielding table top 9.The cast iron hole plug has circular conical surface identical with orienting sleeve and ground plane, and hole plug upper surface 10 is a casting plane, and there are lifting bolt hole and Electromagnetic slings for lifting loads lifting workplace 11 in the centre.
Referring to Fig. 3, a kind of orienting sleeve and hole plug structure with better shielding properties is used to store the higher radioactive waste of activity shown in the figure.The inside surface of cast iron orienting sleeve 12 is a double shield step surface 13, and hole plug is cast with outer conical surface 14, upper surface 15 and hole for hoist 16.
Claims (2)
1. radioactive waste storage device, comprise that storage facility bottom and top are separately installed with fixing steel plate, fixing steel plate is connected with steel tube component and forms hoistway, and the steel tube component upper end is equipped with adapter sleeve, and the adapter sleeve top is the orienting sleeve of iron casting and the shielding hole plug that adopts iron casting.
2. according to claim 1 described radioactive waste storage device, it is characterized in that orienting sleeve, hole plug have the circular conical surface structure that shields step.
