Description
Technical field
The invention belongs to nuclear power plant reactor pressure vessel main pipeline safe end welding line ultrasonic and check technical field, be specifically related to a kind of reactor pressure vessel and take over ultrasonic examination instrument lifting method of operating.
Background technology
Reactor pressure vessel (reactor pressure vessel) is the closed container of settling nuclear reactor and bearing its huge operating pressure, also claim reactor vessel, it is the key equipment in pressurized-water reactor nuclear power plant, the feature such as have that manufacturing technology standard is high, difficulty is large and the cycle is long, and be non-exchange equipment, must guarantee that it is perfectly safe in lifetime reliably at nuclear power station for 40 years.After nuclear power station operation, the heat eliminating medium (water) in core one loop has had high radioactivity, high pollution, and implementing these inspections all needs aid to implement, and checks and needs long-range, robotization.
It is nuclear reactor one loop important component part that reactor pressure vessel is taken over, and takes over and is divided into water inlet and two kinds of adapters of water delivering orifice, takes over and pressure vessel welding, takes over and adopt safe end transition welding between main pipeline.Take over attachment weld and take over safe end weld seam according to checking enforcement of regulations inspection, guaranteeing nuclear safety.
Reactor pressure vessel check according between related specifications at regular intervals, examination scope has comprised reactor pressure vessel main pipeline, the main pipeline scope of examination has main pipeline safe end weld seam, main pipeline and pressure vessel attachment weld.Check main pipeline ultrasonic scan instrument, realize the ultrasonic examination of nuclear reactor pressure container main pipe welding seam.Reactor pressure vessel inspection is implemented during nuclear power station cold-refueling, supervision time window belongs to critical path at outage, the shortening of therefore trying one's best for the reactor pressure vessel supervision time considers that reactor pressure vessel main pipeline ultrasonic examination meeting implements separately simultaneously.Therefore need to develop reactor pressure vessel main pipeline ultrasonic examination instrument.
Above-mentioned nozzle inspection mainly contains two kinds of modes from internal implementation: one, adopts large-scale pressure vessel checking machine system to carry ultrasonic scan device and realizes inspection, as: the French IC MIS of company machine, the SUPREEM of US Westinghouse company, Spain TIME check system etc.; Such large component, can not independently implement, and consumes resource, takies critical path.Two, use the scanning instrument of independently taking over, install or Remote robotization is installed diving and entered to take over to realize and check by personnel's operation aid, take over ultrasonic scan instrument TENIS, the GOLD FISH of ABB AB as the SQUID of Westinghouse Electric diving scanning instrument, Spain's main pipeline and take over scanning instrument etc.Such equipment fitting operation inconvenience, especially power plant's operant level lifting, implementation process complexity.
Therefore, need a kind of small-sized reactor pressure vessel main pipeline ultrasonic examination instrument of development badly, meanwhile, by the design to its lifting method of operating, avoid level lifting in operating process, and then simplify implementation process, improve operating efficiency.
Summary of the invention
The technical problem to be solved in the present invention is: provide a kind of reactor pressure vessel to take over ultrasonic examination instrument lifting method of operating.
In order to realize this purpose, the technical scheme that the present invention takes is:
A kind of reactor pressure vessel is taken over ultrasonic examination instrument lifting method of operating: comprise the following steps:
(1) the instrument preparatory stage: by the front end bondage of checking tool, hang and mount successively chain block, stock and checking tool by nuclear island ring by rope tool;
(2) in the checking tool air inversion stage: nuclear island ring is sling, entering before reactor pressure vessel pond, checking tool turning vertical under Action of Gravity Field is downward;
(3) air stable state handling: maintenance checking tool in stable state, hangs its handling to top, reactor pressure vessel pond by nuclear island ring in air;
(4) leveling of overturning in water: nuclear island ring hangs puts into reactor pressure vessel pond by checking tool, the checking tool balance of upwards overturning under the effect of buoyancy;
(5) place checking tool: use chain block to transfer checking tool to taking over center, the rope tool free end of bondage checking tool is strapped in to anchor point on the bank;
(6) checking tool enters pipe: hung checking tool is sent into adapter inside along taking over axis by mobile suspension bridge and nuclear island ring, the centering rod to checking tool contacts with pressure vessel barrel;
(7) positioning stage is installed: checking tool is location in taking over, is determined and check benchmark;
(8) depart from checking tool: long rod tool and checking tool depart from.
Technical solution of the present invention is used in the Qinshan second phase, 3, No. 4 unit reactor pressure vessels checked, and has passed through technical identification.During the refueling outage of power station, can implement separately, not need to employ main equipment, realize the ultrasonic examination of Nuclear Power Station reactor pressure vessel main pipe welding seam and independently implement, check that response in time; And can be used in conjunction with and can reduce pressure vessel inspection and account for the heap time with large pressurized vessel inspection machine, shorten the pressure vessel supervision time.The application of the invention technical scheme has solved the field test operation implementation of taking over ultrasonic examination instrument, has guaranteed the security of checkout facility, avoids tested equipment to bring infringement simultaneously.
