Description
Technical field
The utility model belongs to Radioactive waste management field, the in particular to low middle Intermediate Level Radioactive in one of the field
Spent resin transhipment loads and uninstalling system.
Background technique
Ion-exchange processing radioactive wastewater is a kind of common and mature treatment process, and application is very extensive.For example,
Reactor operation process, the uranium mill of nuclear fuel cycle leading portion and refinery, back segment spent fuel element water purifying, after
The purifying for the treatment of plant's uranium and plutonium, the production of isotope and application and Nuclear research centre, ion exchange are all used very much.Sometimes,
Ion-exchange is also applied in retired and accident/event handling, is handled in U.S.'s three mile island nuclear station accident with ion-exchange
A large amount of waste liquids.Therefore, a large amount of radioactive spent resin can be all generated every year.Spent resin water content generally 50%~60%, is enriched with
Radionuclide, radiation level is high, belongs to the low wet waste of middle Intermediate Level Radioactive.These spent resins are stored in stainless steel storage tank
It is interior, it is to be processed as radioactive waste etc..
As the construction and safety standard in domestic nuclear facilities base constantly improve raising, Radwastes treatment structure
At independently operated disposal centre, the spent resin that original is stored in different workshops need to be transported to disposal centre and be collected
Middle processing.The transhipment of spent resin need to be completed using radioactive spent resin movement system, complete radioactive spent resin transhipment system
System is made of Load System, transhipment tank car and uninstalling system three parts.The conveying of spent resin uses Hydraulic transportation, water when conveying

The process flow such as Fig. 1 institute for the spent resin handling system that spent resin transhipment tank car is furnished with is put in now low disclosed in the country
Show, which is that the vacuum system being furnished with using transhipment tank car makes the transhipment tank of tank car be in vacuum state, when its vacuum values reaches
When meeting spent resin transport condition to predetermined value, Open valve, spent resin is transferred in tank car transhipment tank from transfer tank.It has shifted
Cheng Hou closes resin supplying channel valve, opens transhipment water conveyance conduit valve, and transhipment water is delivered to tank car from transhipment water pot
Tank is transported, so that the ratio of spent resin and water in tank car transhipment tank reaches the optimum state of transport.It transports after the completion of water conveying,
It opens cleaning aqueduct valve to clean resin supplying channel, spent resin is transported to by spent resin transhipment tank car after the completion of cleaning
Radioactive spent resin receives workshop and is unloaded, and the mixture of spent resin and water is unloaded to the spent resin that spent resin receives workshop
In transfer tank, and resin supplying channel is cleaned, the water of cleaning water tank is sucked tank car using negative pressure, to reach cleaning
The purpose of hose is finally completed unloading.
By utilization in practical projects, it is found that the existing handling system design of spent resin transhipment tank car is excessively complicated,
And there are the following problem needs to improve:
1) spent resin transfer tank is intended only as the container temporarily stored, can not be measured, so that carrying out transport proportion
When, it may cause tank car overload overflow；
2) it after the completion of spent resin conveying, needs to be matched by transhipment water pot to tank car conveying transport water, and if energy
It is matched in loading process using the water of cleaning water tank, transports water pot and cleaning waterpipe and their matched vacuum systems
System and emptying system are exactly extra equipment, these extra equipment not only increase manufacturing cost but also reduce the safety of system can
By property.
