Monitoring system for deformation of nuclear power station safety shell

Abstract

The invention relates to a monitoring system for deformation of a nuclear power station safety shell. The monitoring system comprises a wireless sensor node which is arranged on the surface of the safety shell or a gate hole or in a safety shell chamber for measuring and acquiring safety shell data, a data relay which is connected with the wireless sensor node for receiving and sending the safetyshell data, a data acquiring module which is connected with the wireless sensor node for receiving and sending the safety shell data, and a control centre which is separately connected with the data relay and the data acquiring module for acquiring and processing the safety shell data. The system can set two sets of different data signal receiving networks for an indoor environment and an outdoorenvironment under the outdoor environment with complex multi-surface shielding and a complex environment that room indoor data signal cannot be directly transmitted, so that all-around continuous remote acquiring and monitoring work for the safety shell is completed.

Description

technical field [0001] The invention relates to the field of nuclear power plant monitoring, in particular to a nuclear power plant containment deformation monitoring system. Background technique [0002] In a nuclear power plant, the containment vessel is the outermost building of a pressurized water reactor, which refers to the outer shell building that contains most of the systems and equipment of the nuclear steam supply system, and is used to accommodate the reactor pressure vessel and some safety systems (including the primary circuit main system and Equipment, shutdown cooling system), completely isolated from the external environment, used to control and limit the spread of radioactive materials from the reactor, so as to protect the public from the harm of radioactive materials. Therefore, in a nuclear power plant, the containment compression test is one of the most important tests. During the containment suppression period, close attention must be paid to the defor...

AI Technical Summary

Problems solved by technology

This method does not have the function of wireless transmission, cannot realize the real-time monitoring display, storage and output of the monitoring data during the pressure test, and cannot judge the state of the containment in time

[0005] Part of the wireless monitoring method can only solve the wireless monitoring in the outdoor environment, and cannot complete the wireless automatic monitoring in the indoor environment
