Description

Technical Field

[0001] The invention relates to the field of containment structure integrity testing, and in particular to a containment structure integrity testing system. Background Art

[0002] As the most advanced mainstream commercial nuclear power technology in the 21st century, the third-generation nuclear power technology has achieved remarkable development and progress since the 1990s. Since the early days of reform and opening up, China has introduced the world's advanced AP1000 technology to build third-generation nuclear power plants. A significant difference between the AP series units and the second-generation nuclear power is that the AP series units use steel containment as the third barrier for radiation protection. The steel containment is a key structure to ensure the integrity and sealing of the reactor building, which helps to protect the internal equipment of the nuclear power plant from external influences and can effectively control the spread of radioactive substances in the event of an accident.

[0003] The integrity test of the containment structure is to evaluate the overall structural performance of the containment by inspecting and measuring the overall deformation, strain, temperature and other items of the containment, and to test the structural performance of the containment under the design benchmark accident conditions. During the test, due to the large structure of the containment, there is a certain temperature difference between the measuring points, which has a certain impact on the strain test. At the same time, due to the poor on-site conditions during the test, the requirements for sensors are high, and it is difficult to ensure the measurement accuracy of the sensors in long-term tests.

[0004] The existing scheme has the following problems: long test cycle and complex on-site environment: the test cycle of the containment structure integrity test is long, the amount of data collected is large, and it is necessary to display the data trend of the entire cycle and the data of the whole process. At the same time, due to the large amount of dust on site, the test accuracy and instrument stability are extremely high. Strain temperature effect: the height of the steel containment is about 50 meters, and some areas are located near the gate and are in direct contact with the external environment, resulting in different temperatures at each test point. In addition, the test time cycle is long, and the temperature difference between day and night has a large impact. The displacement measurement deformation is large and the measurement accuracy requirements are high: the containment has large deformation in some areas, requiring the displacement measurement range to reach 200mm, and at the same time, the measurement accuracy requirements are extremely high. Complex system and large test data: The integrity test of the containment structure requires hundreds of sensors, including strain measurement, displacement measurement, temperature measurement, and pressure measurement, and it is necessary to compare the theoretical calculated value with the actual calculated value in real time to show its test change trend. In addition, these instruments need to be connected in series and parallel to form a complete test system. Summary of the invention
