Embodiment Construction

[0030] In order to save the installation cost, those skilled in the art think after conducting research that before installing the steam generator to be installed, three-dimensional measurement of the steam generator to be installed can be carried out first, and the required time for installing the steam generator to be installed can be calculated according to the measurement results. The thickness of the backing plate, make the backing plate, and hoist the steam generator to be installed after the backing plate is made, and before the steam generator to be installed is installed in place, the backing plate is already on the supporting legs, and the steam generator to be installed After the installation is in place, the backing plate is located between the support leg and the body support of the steam generator, that is, after the steam generator to be installed is installed in place, the backing plate is located on the support leg, and the body support of the steam generator is...

Abstract

The invention relates to a nuclear island installation method in a nuclear power plant, and aims to solve the problems of long hoisting time and high installation cost when a steam generator in a nuclear island of the nuclear power plant is installed. The invention discloses a method for installing the steam generator in the nuclear island of the nuclear power plant. The method comprises the following steps of: placing the steam generator to be installed on a support device; detaching a protecting device on the support of the body of the steam generator to be installed; setting a measurement point on the body of the steam generator to be installed; setting a surveying station point at the bottom close to the steam generator to be installed for placing a measurement device; placing a reference scale below the bottom of the steam generator to be installed; measuring the reference scale, the measurement point and the surveying station point by using the measurement device and recording data; processing the measured data by using an industrial measurement system and calculating the thickness of a liner plate; and manufacturing the liner plate and hoisting the steam generator to be installed. Therefore, the installation of the steam generator can be finished by one-time hoisting; and the installation cost is reduced.

Description

technical field [0001] The invention relates to a method for installing nuclear island equipment in a nuclear power plant, in particular to a method for installing a steam generator in the nuclear island of a nuclear power plant. Background technique [0002] When installing the steam generator in the nuclear island of a nuclear power plant, the steam generator needs to be installed to a predetermined height so that the heat pipe opening near the bottom of the steam generator can cooperate with other equipment in the nuclear island. [0003] In the prior art, usually the supporting legs for installing the steam generator are installed first. Then the steam generator is hoisted above the supporting legs by the hoisting device, and the body support on the steam generator body corresponds to the position of the supporting legs, and the hoisting height of the steam generator is adjusted so that it is located at a predetermined height. Measure the vertical distance between the t...
