Heat pipe cooling reactor measuring point optimization arrangement and fault diagnosis method and system

Abstract

The invention discloses a heat pipe cooling reactor measuring point optimization arrangement and fault diagnosis method and system. The position between an evaporation section and a heat insulation section and the position between the heat insulation section and a condensation section in a heat pipe cooling reactor are selected as measuring point positions; the number of measuring point heat pipes at the measuring point positions is determined, and temperature measuring points are arranged on the heat pipes respectively; the temperature at the temperature measuring point, the reactor core power measuring value and the electric power measuring value of the thermoelectric conversion device are collected, accurate simulation calculation of the heat pipe cooling reactor is achieved in combination with the computational fluid mechanics simulation means, information fusion processing is carried out to obtain the temperature of each heat pipe between the evaporation section and the heat insulation section, and the temperature of the heat pipe between the heat insulation section and the condensation section; and whether each heat pipe in the heat pipe cooling reactor works normally or not is judged according to the calculated temperature data, and the number and the positions of the damaged heat pipes are judged. Fault diagnosis can be finally carried out on each heat pipe through measuring point position selection, measuring point number optimization and measuring point information fusion.

Description

technical field [0001] The invention belongs to the technical field of reactor fault diagnosis, in particular to a heat pipe cooling reactor measuring point optimization layout and fault diagnosis method and system. Background technique [0002] Compared with pressurized water reactors, boiling water reactors, and high-temperature gas-cooled reactors, heat pipe-cooled reactors are widely used in aerospace and deep-sea exploration because of their high reliability, low noise, and compact structure. In heat pipe-cooled reactors, heat pipes are energy transfer devices connecting the reactor core and thermoelectric conversion devices, and their safe operation is crucial for heat pipe-cooled reactors. [0003] However, since the heat pipe cooling reactor works in deep sea or deep space for a long time, and the working temperature of the heat pipe is relatively high, generally 1000K, when the heat pipe fails, if it is not found and disposed of in time, it will affect the normal op...

Problems solved by technology

Due to the compact structure of the heat pipe cooling reactor, if each heat pipe is equipped with a sensor to measure the heat pipe, the number of sensors will be huge, and the corresponding signal transmission and collection devices will also increase a lot, increasing the construction and operation costs, and the heat pipe cooling reactor The volume is limited, and the installation cannot be realized due to the limitation of physical space
