Description
Technical field
This utility model is related to irradiated fuel store technical field in nuclear industry, and in particular to a kind of with the weary of screen work component
Fuel dry type reservoir.
Background technology
Spentnuclear fuel, also known as rradiated nuclear fuel, is to live through radiation exposure, used nuclear fuel, typically by nuclear power station
Nuclear reactor is produced.Include substantial amounts of radioelement in spentnuclear fuel, therefore there is radioactivity, if properly do not located
Reason, the health of human body that environment can be had a strong impact on the mankind or other biological for contacting them.
According to statistics, the spentnuclear fuel of the accumulative spentnuclear fuel only 1/3 for drawing off in the whole world is post-treated, and being left 2/3 all can only be temporary transient
Storage, that is, usually said store and AFR storage in heap.At present, major part nuclear power generating sets in the whole world have all run more than
20 years, the spentnuclear fuel quantity drawn off from reactor core all near or above the storage pond useful load in nuclear power plant, be badly in need of by spentnuclear fuel
Transport outward and deal carefully with, will otherwise threaten the safe operation of nuclear power plant.Due to also not building up the radiation that can be run in the world
Property waste geological disposal storehouse, while spentnuclear fuel reprocessing rate is not enough.Therefore, weary combustion has all been built in many nuclear power countries
Expect from heap intermediate storage facilities.Two kinds of wet method storage and dry storage are broadly divided into from heap intermediate storage.The former is generally in Factory Building
Interior construction Spent Fuel Pool, spentnuclear fuel is placed in underwater storage screen work, by boron water circulating cooling spentnuclear fuel and is controlled
Make its reactivity.Wet method storage development is relatively early, and technology relative maturity with high cooling capacity, intensive storage, is easy to fuel handling
The features such as.But wet method storage needs the continuous operation and maintenance of pond cooling system, is also easy to produce secondary waste, and operating cost is very
Height, once and pond breakage be difficult to keep in repair pond in the case where there is water state, therefore nuclear safety, Jing can not have been met gradually
Ji and the requirement of environmental protection.The U.S. was once estimated to the safety of Spent Fuel Pool, as a result showed its anti-natural disaster and terror
Attack ability is simultaneously pessimistic.In Fukushima, Japan nuclear accident, spentnuclear fuel pond loses cooling, and temperature is raised causes the reaction of zirconium water to produce hydrogen
The fried worry for making spentnuclear fuel be directly exposed in air, further having confirmed that people store safety to spentnuclear fuel wet method of air blasting.
Another of spentnuclear fuel is dry storage from heap intermediate storage mode.Hold-up vessel is generally steel sealing to be held
Device, outside provide radioactive shield by metal or concrete, internal cold by air, carbon dioxide or noble gases etc.
But spentnuclear fuel.Dry storage has very big motility, autgmentability and multiformity.Storage sites both can could also in on-site
In off-site, can both be outdoor or indoor, can also be ground or underground storage, can both be to concentrate to put to disperse to deposit
Put, can both be single storage function can also be storage/transportation dual-purpose form, can both be canister can also be mixed
Solidifying soil container.Dry storage container generally adopts passive natural circulation cooling, and operation and maintenance cost are relatively low with respect to wet method.
Dry storage is present due to no liquid, will not produce the self-holding fission reaction of degraded neutron, will not more produce hydrogen and cause blast,
Ensure that its vessel strength can be withstood natural calamities and the attack of terrorism by designing calculating and checking simultaneously.
In prior art, the irradiated fuel assembly of nuclear power station is stored in spent fuel storage rack, the core for generally running now
The heap shape of reactor is different, and irradiated fuel assembly size is not quite similar, and existing spent fuel dry-type storage device storage screen work can only pin
A kind of irradiated fuel assembly of model is stored, spent fuel dry-type storage device does not have versatility.
