Remote monitoring system for nondestructive testing of nuclear power station

Abstract

The invention discloses a remote monitoring system for nondestructive testing of a nuclear power station. The system comprises a monitoring center outside a nuclear island, an intermediate monitoring sub-system in a ring corridor and a terminal controlled object in the nuclear island, wherein the monitoring center controls the terminal controlled object to monitor each service object in the nuclear island; each of the monitoring center and the intermediate monitoring sub-system comprises a display device for displaying the operation state of each service object respectively; when one or more of the service objects in the nuclear island has an abnormal condition, the monitoring center sends a control signal to the intermediate monitoring sub-system to notify the monitoring personnel in the ring corridor to enter the nuclear island to deal with the abnormal condition; and a three-party communication sub-system is arranged among the monitoring center, the intermediate monitoring sub-system and the terminal controlled object. Compared with the traditional monitoring system, the system disclosed by the invention has simple equipment, strong compatibility, high stability and both lighting and warning functions, is easy to operate, and provides better safety guarantee to the nondestructive testing service of nuclear power stations.

Description

technical field [0001] The invention relates to a remote monitoring system for nuclear power plant non-destructive testing. Background technique [0002] A nuclear power plant is a system and equipment that converts nuclear energy released by nuclear fission into electrical energy. Nuclear power plants have high infrastructure investment and produce radioactive substances during actual operation. They run non-stop for nearly 18 months at a time. Therefore, the quality control and operation of nuclear power plants are shut down The inspections put forward high demands. [0003] The non-destructive testing of nuclear power plants is to track and test the equipment of the critical path before the nuclear power is put into production and during the annual overhaul and minor repairs. Due to the special working conditions of the radioactive environment, high requirements are put forward for the equipment and testing methods used. The development of nuclear power inspection busine...
