Specific embodiment
With reference to the attached drawing in the embodiment of the present invention, technical solution in the embodiment of the present invention carries out clear, complete
Ground description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.Based on this
The embodiment of invention, every other implementation obtained by those of ordinary skill in the art without making creative efforts
Example, belongs to protection scope of the present invention.
Basic conception according to the present invention, one of basic security function of reactor is to ensure that radioactivity contains, to guarantee
The operation of the function, the present invention provides a kind of radioactivity envelope disintegration method of research reactor sealing workshop, when generation core meltdown or combustion
When expecting the radioactivity releases major accidents such as element rupture, the containing of reliable radioactive substance is provided.
Fig. 1 is that the research reactor for having radial pattern containing of the embodiment of the present invention seals workshop.Shown in referring to Fig.1, the present invention
Embodiment provides a kind of radioactivity envelope disintegration method of research reactor sealing workshop, comprising:
Nuclear island paint is coated in sealing workshop inner wall surface, the cable of disengaging sealing workshop is passed through into running through with sealing function
Part；
There is the two pass air door of sealing function in the air hose setting of disengaging sealing workshop, it is empty in technique sewer pipe and compression
Electric remote control anti-leakage valve is set on gas general pipeline；
Setting buffering passage room takes seal approach for personnel's discrepancy, this passage room；
Seal approach is taken to equipment hoisting hole again；
Setting removes iodine filter in Emergency Venting System.
In above-mentioned steps, sealing workshop is located above research reactor, and the seal approach of the workshop is for radioactivity packet
Hold most important.A kind of measure is that (the nuclear island paint can be from market in the inner wall surface and/or ground coating nuclear island paint of sealing workshop
Upper acquisition, belongs to the prior art).
In addition, the workshop will necessarily have circuit etc. to be connected to outside, such as by cable mode, therefore, the present invention is implemented
By, by the penetration piece with sealing function, reducing radioactive substance in the cable that will pass in and out sealing workshop and passing through cable in example
Slot leakage between workshop is gone out.Shown in Fig. 1, cable is partially passing through penetration piece 4 into workshop, which sets
It sets and is configured referring to the existing mode of the prior art, it will not be described here.
In above-mentioned steps, the also air hose of workshop and extraneous intercommunication, for the risk of leakage for avoiding air hose, the embodiment of the present invention
In by disengaging sealing workshop air hose setting have sealing function two pass air door (zero-leakage valve 6), can be as far as possible
Reduce leakage；Moreover, further include technique sewer pipe 9 and pneumatic manifold 7 with extraneous intercommunication, respectively phase on these pipelines
That answers is equipped with electric remote control anti-leakage valve.The radioactivity releases major accident such as core meltdown or fuel element failure is occurring
When, it can control these air doors and valve closed, workshop is isolated from the outside world.
In above-mentioned steps, also by setting buffering passage room 11 for personnel's discrepancy, and this passage room takes seal approach；
It is substantially in negative pressure since sealing workshop is for the external world, directly opening door enters and leaves for personnel, will affect internal workshop gas
Atmosphere.By one buffering passage room 11 of setting, when personnel are externally entering, it is first turned on Yishanmen 12, into the buffering passage room
11, it buffers in passage room 11 remained turned-off for entering the another Yishanmen 13 inside workshop at this time, door waits inside workshops after shutting
Between buffering passage room 11 after stable gas pressure, then opens another Yishanmen 13 and enter inside workshop；When personnel go out out of workshop
When, operating procedure is similar.In addition, seal approach also is used to the passage room, it is including but not limited to close to being sticked around two fan doors
Strip of paper used for sealing.
In addition, also taking seal approach to equipment hoisting hole 8 in the embodiment of the present invention.Equipment hoisting hole 8 is for suspending factory in midair
The equipment of room lower part, therefore there is also leaking reflective substance from the hole for hoist 8, in the embodiment of the present invention by
Seal approach is taken around hole for hoist (including but not limited to patch sealing strip, coats nuclear island paint and screw is fixed).
In the embodiment of the present invention, it is additionally provided with emergency ventilation system, is provided with except iodine filter 3, emergency ventilation system
System setting acts on following introduction.
Above-mentioned measure is mainly precautionary measures, i.e., the corresponding means taken before non-generation accident, when occur core meltdown or
When the radioactivity releases major accident such as fuel element failure, the embodiment of the present invention is empty by control technique sewer pipe 9 and compression
The electric remote control anti-leakage valve 13 being arranged on gas general pipeline 7 is closed, and is controlled the two pass valve and is closed, controls normal ventilating system
It closes.These insulating measures make to completely cut off as far as possible inside closed workshop with the external world, almost No leakage.Above-mentioned measure may be implemented in sternly
For sealing workshop pressure not higher than under the conditions of 10kPa, slip is lower than 5% △ V/V/ days when weight accident.
In addition, pressure is excessive to cause danger to prevent in workshop, and the embodiment of the invention also includes: when pressure is higher than in workshop
When setting pressure, emergency ventilation system is opened.Here setting pressure can be set (for example, according to the actual situation
10kPa), after detecting that workshop internal pressure is higher than the setting pressure, the blower valve 2 for controlling Emergency Venting System is opened,
Partial pressure is discharged, after internal pressure is lower than some setting value (such as 9.5kPa), the blower valve 2 pass can also be controlled
It closes, continues that workshop inside seal bored.
Based on similar design, the embodiment of the present invention also provides a kind of research reactor sealing workshop 100 for having radioactivity containing,
Wherein, 100 inner wall surface of sealing workshop is coated with nuclear island paint；And the cable configurations of disengaging sealing workshop are by having sealing
The penetration piece 4 of function.
It further include the air hose of disengaging sealing workshop in some embodiments, the air hose is provided with the two pass wind of sealing function
Door.Optionally, the electric signal of these two pass air doors is connected to central control system, and the opening and closing of air door can be uniformly controlled by it.
In some embodiments, sealing workshop 100 further includes technique sewer pipe 9 and pneumatic manifold 7, technique sewer pipe 9 and pressure
Electric remote control valve is respectively provided on contracting air header 7.The setting of these pipelines and control mode are referring to described above.
In some embodiments, further include equipment hoisting hole 8 and for personnel enter and leave buffering passage room, the equipment hoisting hole and
Buffering passage room takes seal approach.Their set-up mode is also referred to described in above-described embodiment, and it will not be described here.
Further include emergency ventilation system in the embodiment of the present invention in some embodiments, is configured to work normally in reactor
When close, in the event of an accident and workshop internal pressure be greater than setting pressure when it is open-minded.In some embodiments, the emergency ventilation
It is additionally provided in system except iodine filter 3.For being adsorbed first by the way that iodine filter 3 should be removed after opening emergency ventilation system
Radioactive substance iodine, then pass through blowdown stack 1 to outside drain.
