Description
Technical field
The invention belongs to nuclear power plant reactor service technique fields, and in particular to a kind of reactor protection tube assembly bourdon tube
Replace simulation training platform.
Background technology
Field gulf nuclear power station uses Russia VVER-1000 type presurized water reactor units, and type of reactor is B-428 types.Reactor
Tube assembly bourdon tube is protected to be mounted on protection tube assembly convex shoulder, is coordinated with concave station in upper element, in upper element and protection
Elastic connection is established between tube assembly.When implementing to seal to reactor primary sealing area using kingbolt, bourdon tube flexible deformation
The reaction force of generation makes the sealing of primary sealing area relatively reliable.When main pump is run, bourdon tube is additionally operable to prevent core barrel
Floating and vibrations.Therefore, correct, the reliable installation of bourdon tube plays to pass normal reactor operation, power station normal power generation
Important role.
As shown in Figure 1, protection tube assembly bourdon tube shares three, each bourdon tube is the cylinder with certain radian
Shape, three bourdon tubes are evenly distributed on the convex shoulder of protection tube assembly, are spliced into a circle, the structure of three bourdon tubes and tight
Gu mode is consistent.The replacement of protection tube assembly bourdon tube is operated in protection tube assembly time and installs into rear progress, is as follows：
(1) lock washer is moved toward straightening with screwdriver and fitter's hammer can be pounded；
(2) bolt is backed out, bolt and lock washer, gasket are put into fastener pallet；
(3) old bourdon tube is removed, is hung out with crane, be put into designated position；
(4) the new effective crane of compressed spring is hung near protection tube assembly；
(5) bourdon tube is installed on the convex shoulder of protection tube assembly, by the bolt hole of bourdon tube and protection tube assembly convex shoulder
Upper screwed hole is to good；
(6) four gaskets and four check washers are installed, pad hole is aligned with the threaded hole on protection tube assembly convex shoulder；
(7) screw thread of four bolts is coated into molybdenum disulfide 232, bolt is inserted into threaded hole and with torque Mkp=80+
5N.M is tightened；
(8) lock washer dovetail shaped lock point is bent on the adjacent stupefied side of bolt two, while will lock vertically upward with screwdriver
The tight gasket other end is bent on gasket vertically downward, prevents bolt looseness；
(9) more changing jobs for other two bourdon tubes is completed according to above-mentioned steps.
Protection tube assembly bourdon tube in more changing jobs step more difficult, that the used time is longer be：Lock pad in step (1)
Piece is not easy to move toward straightening, and time-consuming；New bourdon tube is being installed to protection tube assembly convex shoulder due to accuracy of manufacture error in step (5)
Installation site takes longer, there is a situation where to need bourdon tube hole " reaming "；Step (7) and step (8) are in practical operation
When need operating personnel have rich experience, while torque adjust lock washer position, with ensure after complete torque
Lock washer dovetail shaped lock point is located on the adjacent stupefied side of bolt two, and the lock washer other end is located at any one stupefied side of gasket
On.
Since protection tube assembly bourdon tube is replaced, operation difficulty is big, it is long to expend the time, collective dose is high, and there is an urgent need for exploitations
A kind of reactor protection tube assembly bourdon tube replaces simulation training platform in overhaul early period to service personnel's intense session.
Invention content
The technical problem to be solved in the invention is：In view of protection tube assembly bourdon tube is replaced, operation difficulty is big, consumes
Time-consuming length, collective dose are high, propose that a kind of reactor protection tube assembly bourdon tube replaces simulation training platform, in overhaul early period
To service personnel's intense session, the level of skill of service personnel is improved, reduces the time used in this work, reduction personnel are shone
Dosage.
It is described that technical scheme is as follows：
A kind of reactor protection tube assembly bourdon tube replaces simulation training platform, is fastened including a bourdon tube, bourdon tube
Part, backing plate and support element, bourdon tube are fixed on by bourdon tube fastener above backing plate, and support element is connected to below backing plate.
The bourdon tube is equipped with several penetrating bolts hole.
The backing structure is the tablet with certain radian, and radian protection tube assembly corresponding with single clarinet is convex
Shoulder radian is identical；Backing plate is equipped with several threaded holes, and position is corresponding with the bolt hole position of the bourdon tube above backing plate；
Threaded hole internal thread is identical with protection tube assembly convex shoulder screw thread.
The bourdon tube fastener includes gasket I, gasket II and bolt, when being installed to bourdon tube, makes bourdon tube
The screw thread hole site of bolt hole and backing plate corresponds, and for each bolt hole, places successively be put into gasket II inside it
With gasket I, the pad hole of gasket II and the pad hole of gasket I are corresponding with backing plate screw thread hole site, and bolt is passed through bourdon tube
It is placed with the bolt hole of gasket II and gasket I and backing plate threaded hole and tightens.
Preferably：Bourdon tube is set there are four penetrating equally distributed bolt hole：Bourdon tube initial and end end respectively sets one
A bolt hole respectively sets a bolt hole at 1/3 radian of bourdon tube and at 2/3 radian.
Preferably：For the supports support below backing plate, height makes protection tube assembly bourdon tube more change the mold
It is identical with device height during field operation to intend training platform height.
Beneficial effects of the present invention are：
(1) reactor protection tube assembly bourdon tube of the invention replaces simulation training platform, according to actual size 1:1
Ratio makes, and simulation works well：Service personnel is giveed training with the simulation training platform of the present invention before overhaul, hence it is evident that carry
The high level of skill of personnel, significantly reduces the activity duration, so as to significantly reduce personnel's radioactive dose.
(2) protection tube assembly bourdon tube of the invention replace simulation training platform in field gulf nuclear power station T108, T208 and
It is applied successfully in the work of T109 overhauls ex-period training, is mainly used for carrying out bourdon tube dismounting, bullet to participating in reactor service personnel
The trainings such as reed pipe installation, fastener adjustment and bourdon tube position measurement.The result of training of the simulation training platform of the present invention is
Through being embodied in overhaul three times.According to statistics, it is 0.27-0.47mSv/h that bourdon tube, which replaces working environment dosage rate, during overhaul, average
Dosage rate 0.37mSv/h.The above-mentioned bourdon tube of overhaul three times replaces average used time 1.5h, and than before, more unused training platform is to overhauling people
The 0.5h when overhaul of member's training is economized on.By theoretical calculation：More being changed jobs by bourdon tube needs in terms of 3 service personnel, shortens working hour
0.5h can reduce collective dose：0.37mSv/h × 3 people × 0.5h=0.555man.mSv.Actual effect：Above-mentioned overhaul three times
Protection tube assembly bourdon tube more change jobs generate collective dose be respectively 1.751man.mSv, 1.673man.mSv,
1.617man.mSv, and this work averagely generates collective dose in the overhaul that unused training platform trains service personnel before
2.25man.mSv.Therefore, service personnel being giveed training with training platform can at least make bourdon tube replace team's agent
Amount reduces 0.5man.mSv.
