Embodiment Construction

[0030] Embodiments of the present invention will be specifically described below in conjunction with the accompanying drawings.

[0031] During the operation of the unit, when the secondary circuit water enters the steam generator for heat exchange, the impurities in the water will be deposited on the secondary side tube plate of the steam generator (Steam Generator, hereinafter referred to as SG), and will continue to expand, resulting in heat exchange Pipe wall depressions and circumferential cracks may occur at the pipe ends. The purpose of steam generator flushing is to remove these deposits on the tube sheet plane to avoid depressions and cracks on the tube wall.

[0032] During the flushing process of the evaporator generator, the flushing quality is controlled through the chemical supervision of the flushing water; through the chemical analysis of the residue, the technical level of the evaporator flushing, the corrosion of the secondary circuit pipeline and the water q...

Abstract

The invention discloses a nuclear power plant vapor generator washing and sediment reaction device which comprises three main parts, namely, a reaction component, an acid gas absorption and water discharge component and a liquid collection and metering component. The parts are delicately designed and connected, the number of the components of the experiment device is minimized on premise of ensuring experiment accuracy and precision, the volume of generated hydrogen is detected by using a drainage method, and thus precise, rapid and convenient tests on the content of Fe in sediment of a nuclear power plant vapor generator can be achieved.

Description

technical field [0001] The present invention relates to a nuclear power plant maintenance device, more specifically, relates to a nuclear power plant steam generator flushing sediment reaction device, which is mainly used for the analysis of Fe content in the steam generator flushing sediment during the major repair of the nuclear power plant, and provides for evaluating whether the steam generator flushing is excessive. in accordance with. Background technique [0002] Steam generator flushing is an essential measure to maintain the evaporator during the overhaul of nuclear power plants, but excessive flushing will cause damage to the steam generator, and the result of the sediment reaction is an important basis for judging whether the steam generator is excessively flushed. The sediment reaction gas collection device is used for the measurement and evaluation of the sediment reaction results. Its main principle is to measure the Fe content in the sediment by measuring the ...
