Problems solved by technology

[0003] At present, the full-scale test is mainly used in China to explore the strength performance of the containment by simulating the accident in the actual containment. Although this method can simulate the actual situation more accurately, the test cost is relatively large, and it may also affect the strength of the containment. Damage to the structure does not meet the requirements of sustainable economic development

Abstract

The invention relates to a containment local component strength test device, which comprises a rigid counterforce base, a radial actuator group, a hydraulic oil loading mechanism and a pair of circumferential sliding support mechanisms; wherein the rigid counterforce base is provided with an actuator group placing groove, the radial actuator group is arranged in the actuator group placing groove and is communicated with the hydraulic oil loading mechanism, and the annular sliding supporting mechanisms are arranged on the two opposite side walls of the actuator set containing groove respectively. Compared with the prior art, the device has the advantages of being simple, convenient to disassemble and assemble, low in cost, suitable for tests of containment vessels of different sizes and the like, the load condition and boundary conditions of the containment vessel under accidents can be accurately reflected, the purpose of researching the strength performance of local components of the containment vessel can be achieved, and the requirements for economy and sustainable development are met.

Description

technical field [0001] The invention belongs to the technical field of containment testing, and relates to a device for testing the strength of partial components of a containment vessel. Background technique [0002] The containment is the last safety protection barrier for nuclear power plants to prevent the spread of radioactive substances to the external environment. The role of the environment to isolate internal systems and prevent the spread of radioactive material to the outside world in the event of rare dehydration accidents and severe accidents. When a reactor accident occurs, a large amount of radioactive material and high-temperature, high-pressure steam-water mixture can be contained and isolated by the containment to prevent radioactive pollution to the surrounding environment of the nuclear power plant. Due to the importance of containment, it has always been the focus of research in engineering circles at home and abroad. [0003] At present, the full-scal...
