Description
Technical field
The present invention relates to reactor pressure vessel supporting technology field, be specifically related to a kind of reactor pressure vessel band pre-
The skirt-type supporting arrangement of embedded part.
Background technology
Along with the growing tension of the energy, nuclear power cleans as one, the reliable energy, comes into a stage of quickly sending out,
The construction of nuclear power station also gets more and more.
Reactor pressure vessel is one of key equipment of whole nuclear power plant reactor and primary Ioops system, is pressure boundary
Important component part, in nuclear power station, in-pile component is fixed and supported to reactor pressure vessel, core internals, control rod drive
Motivation structure, heap roof construction etc..In containment, for effective fixing reactor pressure vessel, it is ensured that the peace of whole reactor
Row for the national games, it is necessary to supporting structure is set.The weight of whole nuclear power plant reactor is relatively big, in the work of whole reactor and shutdown state
Between, the pressure of whole coolant system, temperature to change, and simultaneously it is also contemplated that the impact of seismic (seismal, therefore, support
Structure, on the premise of guaranteeing to bear pressure vessel static load, also should bear reactor dynamic loading under all kinds of operating modes.
Reactor supporting is the important component of nuclear plant pressure vessels reactor system, at common power station reactor supporting knot
In structure, saddle modularity supporting structure being usually taken, its supporting is positioned at the axial medium position of pressure vessel, i.e. pressure vessel turnover
Adapter position at mouth pipeline, surrounding is supported by concrete base station.This existing supporting structure has blocked reactor pressure vessel
Important weld seam, is not easy to inservice inspection.Especially for high throughput test heap, carry out sample radiation test for a long time and produce coordination
The needs of element, it is desirable in the whole life span of test reactor, be required to whole pressure container cylinder weld seam is carried out inservice inspection,
And inservice inspection requires all important weld seams of cylinder as can not be supported by pressure vessel, the peripheral location of concrete base station etc. a time
Other equipment of road can not have shelter.High throughput test heap reactor pressure vessel device its periphery in actual motion is screen
Covering water, periphery lacks supporting base station, and existing supporting arrangement starts supporting from the middle part of pressure vessel, not only can stop weld seam position
Put, and cannot realize, it is known that on power station, tradition supporting form can not meet support needs.
Based on this, study and develop the skirt-type supporting arrangement devising a kind of reactor pressure vessel band built-in fitting.
Summary of the invention
The technical problem to be solved is that existing pressure vessel supporting structure has blocked reactor pressure vessel
The important weld seam of cylinder, is unfavorable for the inservice inspection of test reactor pressure tight seam, and the surrounding of pressure vessel lacks supporting base station,
Support needs can not be met, present invention aim at providing the skirt-type of a kind of reactor pressure vessel band built-in fitting to prop up and take up
Putting, use skirt support, the upper end of skirt support is welded with reactor pressure vessel, and foundation bolt is passed through in the lower end of skirt support
It is fixed on built-in fitting at the bottom of reactor, above-mentioned skirt support is set, solve existing reactor pressure vessel supporting structure and block
Container welding is not easy to inservice inspection, and whole skirt support can solve the problem that and pressure vessel is carried out effectively supporting problem.
The present invention is achieved through the following technical solutions:
The skirt-type supporting arrangement of a kind of reactor pressure vessel band built-in fitting, including skirt support, built-in fitting, stop block, skirt
The upper end of formula bearing is connected with reactor pressure vessel, and the lower end of skirt support is fixed on built-in fitting, and stop block is through pre-buried
Part is embedded in concrete foundation.
In technical solution of the present invention, skirt support is connected with the lower end of reactor pressure vessel, and concrete connected mode is preferred
Skirt support welds with the lower end of reactor pressure vessel, and the lower end of skirt support is fixed on embedded part structure, props up at skirt-type
Before seat is installed, built-in fitting is pre-installed in concrete foundation, is completed pressure vessel is determined by through built-in fitting stop block
Position, the overall structure of formation implements the supporting to reactor pressure vessel.This supporting arrangement makes the important weld seam of pressure container cylinder
The most exposed outside, facilitate the inservice inspection of test reactor pressure vessel.And existing nuclear power plant reactor pressure vessel props up and takes up
Putting, its bearing position is mainly disposed to pressure vessel position of centre of gravity, and surrounding is supported by concrete base station, has blocked important weldering
Seam, and the inspection of shell weld seam is around implemented without the useful space.And in technical solution of the present invention, by supporting arrangement in reaction
Core pressure vessel lower end, supporting arrangement welds mutually with pressure vessel, then is fixed on built-in fitting, and built-in fitting is fixed on concrete
In basis, built-in fitting bottom welding has T-shaped gusset, and top has and is available for the duct that reinforcing bar passes, and can reactor operating loading be had
Effect dispersion is to concrete base station, and such constructional device only need to arrange concrete foundation, shell bottom reactor pit
Part, without concrete base station, solves original structure form and blocks receptacle and want weld seam, be unfavorable for in-service monitoring inspection problem.With
Time, skirt-type supporting arrangement passes through skirt support, built-in fitting, the setting of stop block, it is achieved supporting and the location to pressure vessel, anti-
Only it moves horizontally, and has good stability, beneficially normal reactor operation.The technical program can solve existing
Bearing apparatus blocks the technical problem of weld seam, and the overall structure that used of technical solution of the present invention and connected mode thereof are in existing skill
Art, common knowledge the most do not disclose, the combination enlightenment of this technical problem that also do not achieves a solution from other supporting structures.Mesh
Front not for supporting structure during high flux experiment reaction pressure vessel operation, existing nuclear power plant reactor supporting arrangement is also
Can not meet surrounding be shield water, cylinder weld seam can operational monitoring pressure vessel supporting.
In the technical program, the effect of skirt-type supporting arrangement is that supporting includes reactor pressure vessel, in-pile component, fuel
The equipment such as assembly, C&P systems and the weight load of accommodated fluid, and reactor pressure vessel is positioned.Wherein,
Skirt support is to support reactor pressure vessel and be secured to the supporting parts of certain position, bears pressure vessel
Vibration during work and seismic (seismal.The version of bearing is mainly determined by the shape of pressure vessel self pattern and bearing,
Being divided into vertical support, horizontal support and supports of spherical vessel three class, skirt support is the one of spherical bearing, its structure and principle
Common knowledge for art.Built-in fitting is the component being imbedded in advance in concrete foundation, for skirt support and reaction
Core pressure vessel links, and beneficially reactor pressure vessel is fixing.Built-in fitting is bearing and the intermediate carrier of concrete base station, one
