Abstract

The invention discloses a creep irradiation device suitable for stress static loading. The device comprises an upper shell, a lower shell, a threaded power transmission mechanism, a displacement rod,a force measuring part, a movable sample holder I, a movable sample holder II and a fixed sample holder, wherein the threaded power transmission mechanism and the displacement rod are arranged in theupper shell. The force measuring part is arranged in the lower shell. The device is suitable for a stress static loading creep irradiation device, a pipeline does not need to be connected to the outside of a research reactor, and the influence on the stability of the whole device due to the impact of cooling water in the research reactor on the pipeline is avoided. By utilizing the creep irradiation device suitable for stress static loading, simultaneous loading of test environments such as stress, temperature, neutrons and the like of a test sample is realized, meanwhile, the device is compact in structure, a pipeline does not need to be led out of a reactor, and the test reliability and safety are improved.

Description

Technical field [0001] The invention belongs to nuclear power materials, and specifically relates to a creep irradiation device suitable for stress static loading. Background technique [0002] Nuclear power material technology has always been one of the most critical technologies supporting the development of nuclear power, and material issues are also one of the bottlenecks restricting the rapid development of nuclear power technology. As the first barrier to contain radioactive materials, the fuel cladding is a key component to maintain the structural integrity of fuel elements and prevent the leakage of radioactive materials. During its service in the nuclear power plant reactor, the fuel cladding needs to withstand the coupling effect of high temperature, stress and strong radiation field for a long time, and its length changes with time, that is, "creep". Creep not only causes deformation of the cladding material, but also damage and fracture effects, which may cause the f...
