Description
Technical field
The present invention relates to a kind of tent components used in processing nuclear material field.The invention particularly relates to a kind of nuclear radiation protection and disposable tent components, such as glove box (glovebox), this assembly is for intervening (intervention) to radiocontamination thing, so that described intervention is to carry out under the environment sealed.Described tent components includes at least one and seals shell and outer support part.This intervention includes such as to the dismounting of nuclear device and overhaul.
Background technology
Nuclear device typically requires intervening-and certain time point-open described nuclear device at this time point in their service life has release radioactive material and exposes the risk of α, β and/or gamma-rays and/or neutron.
Nuclear device is mixed oxide fuel (' MOX such as,) or other are containing plutonium fuel production device factory harbour, such as pollute glove box, fuel will be consumed β/gamma-electric cell and α/β/gamma-electric cell are reprocessed, for producing the fresh fuel comprising a small amount of actinides.
One of which intervention refers to scrapping of nuclear device.Scrap and may be for whole device, for instance nuclear device close after, scrap can also be part, for instance the part of described nuclear device need reequip time, or during the service life of described device for prolonging in.
Overhaul is another kind of the intervention, opens nuclear device and has the risk of release pollutant.Such as, when changing large-scale or heavy process components or window, sometimes with the destruction abandoning the core technique shell reducing with size and polluting of process components.
During intervening, for instance scrap and overhaul, take the risk that multiple preventive measure is illuminated to the release and human body reducing radiocontamination granule.Operator personnel not only need the internal radiation to taking in and suck these radiocontamination granules and cause to protect, when also wanting, the external radiation from radiation is protected, for instance radiation exceedes control dose limit and/or reaches according to the ALARA (" amount that the floor level ") principle that can rationally accomplish is determined.Thus as a result, before described intervention, nuclear fission material is usually collected and is removed from nuclear device.Thus, the exposure of fission neutron is insignificant in general.Nuclear pollution can be removed subsequently in maximum reasonable degree.Another kind of prevention is to provide intervention shell, for instance Alpha's containment member, glove box or disposable protective tent components, and described protective tent components is positioned to be needed to remove or around the nuclear device of service.
When Alpha's containment member or glove box are used as intervening shell, described nuclear device (such as described glove box) is firstly the need of transporting to the closing space being positioned at factory somewhere.However, it is contemplated that the exposure of radioactive particulate, this transport is expensive and has risk.
Described nuclear device enters shell by using " pack " technology of a kind of routine to realize.Technology below can keep the sealing of described casing when introducing equipment or other materials.For above-mentioned purpose, described equipment or material are arranged in sack, and wherein open side is provided with O.The latter is fixed in the circumferential groove of the entrance in described closing space, so that this sack is overlapping with another sack of Already in porch and closes the latter.In order to enter described equipment or described material, the latter is drawn in closing space together with described sack.Once described equipment or material are located therein, described entrance is closed by described sack, stored with equipment or material in sack.
Described away carries out intervening required equipment, and under the state being in opposite outer environmental sealing.Stand in the inside of Alpha's containment member or operate electric power or Aeroassisted instrument the operator outside cutting box, for instance removal tool.The entrance and exit of described operator is by adaptive gas lock perception in advance, and the discarded part that cutting operation causes is by using waste storage drum or cutting box against described Alpha's containment member to remove.
When working in Alpha's containment member, operator is equipped with seal coat and breathing apparatus.Lead apron can be worn when being exposed under gamma-rays.
In order to avoid described nuclear device being transported out of bounds areas and the risk of produced expense and exposure, record a kind of protective tent equipment of use, such as at the patent application that publication number is DE4040115t6 and paper " dismounting polluting glove box for plutonium puies forward art: from the experience of stopping production First Year ", R.BAUMANN, P.FABER, the six radiate and scrap refuse international symposium, kontec2004, Berlin, Germany, in March, 2004.
How glove box described in document below transports the protective tent components being positioned at operative employee factory, and described protective tent components is erected at around described glove box at the scene.Described protective tent components includes the shell of flexibility and sealing, and the form factor that described shell is customized into the described glove box to remove adapts, it is possible to equipped with glove and window, and keep vacuum by the ventilating system of oneself.Described tent components could be included for the cutting equipment performing to remove, and described cutting equipment runs when isolating with external environment condition.Stand in the operator outside described protective tent components and operate described removal tool.Instrument that these operators are similar when can equip with operation sequence glove box and monitoring device.The refuse that described cutting operation produces can be discharged by the waste storage drum being connected with protective tent components in a sealing fashion.
The shortcoming of described known protective tent components is that it is not enough to the radiation protection of operator.It is true that failed by plutonium 241, the uranium/plutonium and the β of americium 241 that produce and gamma-rays expose, and the risk that the neutron that particularly in major part nuclear device, nuclear reaction produces exposes and produces can not be underestimated.
Therefore, needing to remove or process equipment and its shell of service are highly contaminated when described, operator is currently by wearing what suitable clothes prevented from exposing, including lead apron of the prior art.But lead apron has this lower shortcoming: the operator wearing it can not be reduced the dose rate of neutron by them, is only capable of preventing gamma-rays.Additionally, these lead aprons are heavy, the motility of restriction operator, and bring added burden when performing physical demands and dangerous cutting work in known protective tent components to operator.
Summary of the invention
It is an object of the invention to provide a kind of protective tent components, the operator being exposed in neutron and α and gamma-rays can be provided protection by this assembly, and provides a kind of protective tent components, and nuclear device can be carried out safety operation by this assembly.
