System and method for monitoring and positioning sound of primary loop pressure vessel of high-temperature gas cooled reactor

Abstract

The invention relates to the technical field of high-temperature gas cooled reactor monitoring, in particular to a high-temperature gas cooled reactor primary loop pressure vessel sound monitoring and positioning system and method. The at least four first sensors are arranged on the flange of the top cover of the pressure container at intervals; the at least four second sensors are arranged on a supporting lug frame of the pressure container at intervals; the at least four third sensors are arranged on the hot air guide pipe shell at intervals; the fourth sensors are arranged on the flange of the top cover of the steam generator, and at least four fourth sensors are arranged at intervals; the fifth sensors are arranged on the lower flange of the fan shell barrel, and the number of the fifth sensors is at least four; the sixth sensors are arranged on a lower flange of the fan shell supporting cylinder, and the number of the sixth sensors is at least four; the seventh sensors are arranged on supporting lug frames of the steam generator, and at least four seventh sensors are arranged at intervals; the control structure is in signal connection with the sensor. The problem that the high-temperature gas cooled reactor primary loop pressure container cannot locate sound is solved.

Description

technical field [0001] The invention relates to the technical field of high-temperature gas-cooled reactor monitoring, in particular to a sound monitoring and positioning system and method for a primary circuit pressure vessel of a high-temperature gas-cooled reactor. Background technique [0002] At present, my country has begun to build and use the fourth-generation nuclear power technology. The high-temperature gas-cooled reactor has the characteristics of good safety and high operating temperature. However, there are a large number of main flanges in the design and operation of nuclear island primary circuit reactor pressure vessels, hot gas conduits, steam generators and other core pressure vessel equipment. Due to uncoordinated deformation of some matching flanges, misalignment will occur, and individual flanges with large misalignment will make noise, which will adversely affect the safety and sealing of equipment operation. In actual operation, the distance between ...
