Embodiment Construction

[0011] Take the wave tube S002 as an example for illustration.

[0012] The measurement method of the surge tube in the coolant circuit of a nuclear power reactor is divided into two steps:

[0013] Preparation before measurement:

[0014] l. Install the laser transmitter on the tripod, use the coaxial cable to connect the laser transmitter to the control box, and use the network cable to connect the control box to the laptop. Turn on the machine and preheat for 15 to 20 minutes.

[0015] 2. Draw a grid of measuring points on the surface of the measured fluctuating pipe body. The selected points are required to reflect the real processed surface as much as possible, and the best description of the state of the pipe body has been achieved.

[0016] 1. Measurement process:

[0017] l. According to the shape and placement of the wave tube, select the measurement station of the laser tracker, the location of the subsequent transfer station and the number of transfer stations. ...

Abstract

The present invention provides a nuclear reactor coolant circuit fluctuation tube measuring method. Firstly, a straight tube section and a circular section are measured and then the data processing is carried out. According to the method, the AP1000 nuclear reactor coolant circuit fluctuation tube 3D space actual state can be reproduced in SA software, and the problem that the data generated by a conventional measurement data and the installation of a post fluctuation tube can not be effectively connected is solved. The method is suitable for the method application of nuclear reactor coolant circuit fluctuation tube measurement.

Description

technical field [0001] The invention relates to the technical field of measurement, and relates to a method for measuring fluctuation tubes in the coolant loop of an AP1000 nuclear power reactor. Background technique [0002] At present, the measurement work of the fluctuation tube of the coolant loop of AP1000 nuclear power reactor is in the stage of just contact, research and improvement in China. A set of wave tubes consists of 5 pieces, numbered S001, S002, S003, S00, and S005. Because the external dimensions involve design requirements such as elevation angle, depression angle, and helix angle, it is difficult to measure the above-mentioned space dimensions by conventional measurement methods such as scribing. Therefore, the three-dimensional space measurement method based on laser tracker and SA measurement software can well solve the above measurement problems. Contents of the invention [0003] In order to realize the measurement of the wave tube, the invention pr...
