Abstract
The invention relates to a simulation test device for metering flow of a fuel assembly. The contour of the simulation test device is identical to that of the fuel assemble, the inner side of which is provided with a closed flow-path in which is provided with a positioning comb and a simulation fuel plate. The positioning com is a com-shape positioning plate with several side-by-side grooves and the simulation fuel plate is fitted in the grooves of the positioning com. The length of the simulation fuel plate is less than that of the practical fuel plate. At rear end of the simulation fuel plate and in the space of the closed flow path is provided in turn with a vortex flow meter and a resistance regulation plate which is a plate with through holes. The device avoids the error resulted by adopting pressure-guiding pipe to do metering. Advantage: raised precision and reduced cost.
Description
Technical field
The invention belongs to simulation test device, be specifically related to a kind of simulated assembly that is used for the fuel assembly flow measurement.
Background technology
When reactor core assignment of traffic simulation test, the accuracy of flow measurement is very important, is related to the safety of reactor.In order fully to understand the flow characteristics of water in nuclear reactor, the basic test data are provided for the design of reactor thermal-hydraulic and in-pile component, need carry out the whole hydraulic simulation test of nuclear reactor.When hydraulic simulation, must adopt the simulated fuel assembly of simplification to replace the prototype fuel assembly to carry out the research that assignment of traffic is tested, so that reach economic, practical purpose.
At home in the plate shape fuel assembly reactor core assignment of traffic experimental study of adopting first, the profile of simulated assembly and internal structure are similar substantially with fuel assembly, to satisfy Testing requirement, but because the inner space of plate shape fuel assembly is little, so the simulated assembly inner space is also little, the routine measurement instrument is difficult in its positioned inside, can only adopt this moment in the sheet separation and carry out flow measurement with the mode of many group pressure guiding pipes, its corresponding differential pressure measurement instrument can only be located at the outside of reactor core, but the differential pressure measurement of pressure guiding pipe and channel size with and the roughness on surface etc. relevant, when pressure reduction is converted into flow, be subjected to channel size with and the influence of these aspects of roughness on surface, cause the flow measurement precision lower, in addition, the flow measurement of an assembly needs the stack conversion of many group differential pressure measurements to obtain, this brings the error of stack can for the flow measurement of assembly, cause the precision of assembly flow measurement lower, and adopt many group measurement instruments to measure a flow parameter, increased experimentation cost.
Summary of the invention
The object of the present invention is to provide the high simulated assembly that is used for the fuel assembly flow measurement of a kind of measuring accuracy.
The present invention is achieved in that a kind of simulated assembly that is used for the fuel assembly flow measurement, its profile is consistent with fuel assembly, its inboard is made as the enclosed runner, in the enclosed runner, be provided with location comb and analog fuel plate, the location comb is for having the pectination location-plate of some grooves side by side, the analog fuel plate is located in the groove of location comb, the length of analog fuel plate is less than the length of natural fuel plate, also be provided with turbo flow meter and resistance adjustable plate successively in the rear end of analog fuel plate, enclosed flow channel space, the resistance adjustable plate is the plate that has through hole.
The length of analog fuel plate of the present invention is less than the length of natural fuel plate, therefore the inner space of simulated assembly increases, turbo flow meter can be put into simulated assembly and measure, the flow measurement distortion that brings is then regulated correction by the resistance adjustable plate because simulated assembly shortens.The present invention has avoided the error that adopts pressure guiding pipe to measure, and has therefore improved the precision of flow measurement.In addition, owing to do not need many group measurement instruments to measure, reduced experimentation cost.
