Abstract

The invention discloses a nuclear power plant integrated monitoring and analysis system for monitoring and analyzing test data during the pressure test of the containment vessel of a nuclear power plant. The system comprises a monitoring component for monitoring the structural state, the leakage rate, the fire condition, the crack state and the appearance state of a containment vessel during the pressure test, and transmitting monitored data; a data analysis component connected with the monitoring component and used for receiving the monitored data for analysis to obtain an analysis result, and determining whether the containment vessel is in a normal operation state based on the analysis result; a display and alarm component connected to the data analysis component and used for receivingand displaying the analysis result and a determined result, and giving an alarm when the containment vessel is an abnormal state. The invention also discloses a nuclear power plant integrated monitoring and analysis method. The nuclear power plant integrated monitoring and analysis system and method make the data all in the same system, facilitate data management, solve data asynchronization, andprovide early warning.

Description

technical field [0001] The invention relates to the field of nuclear power plant management, in particular to an integrated monitoring and analysis system and method for nuclear power plants. Background technique [0002] In nuclear power plants, the containment pressure test is one of the most important tests in nuclear power plants. It simulates and verifies the tightness and strength performance of the containment under the conditions of reactor coolant loss accident (LOCA). In order to comprehensively evaluate the performance of the containment, a large amount of data needs to be measured and calculated and analyzed during the containment compression test. [0003] At present, nuclear power plants at home and abroad need to monitor the overall leakage rate data, EAU instrument data, appearance inspection data, and fire monitoring data for containment suppression tests. In the prior art, these data and analysis systems are independent and decentralized. The containment p...
