Description

technical field [0001] The invention relates to the technical field of radiation resistance performance evaluation equipment and methods of nuclear energy structural materials, in particular to a high-temperature radiation creep device. Background technique [0002] At present, using heavy ions instead of neutrons to irradiate materials and simulate the radiation resistance of nuclear energy structural materials is an internationally recognized method, because ion irradiation has many advantages such as economy, safety and speed. To utilize ion irradiation, it is necessary to connect the irradiation target chamber with the accelerator beam pipeline. At present, there are many kinds of irradiation target chambers in China, such as ordinary high-temperature target chambers, which use heating wires to heat the sample target holder, so that the irradiated samples can be irradiated at high temperatures, and the simulated materials can be irradiated at high temperatures.

During the long-term service of materials, irradiation creep will reduce the mechanical properties of materials and seriously affect the safety of nuclear energy

The radiation creep performance of nuclear energy structural materials is very important to evaluate the performance of the material. So far, there is no target chamber suitable for radiation creep research in China. For example, the existing high-temperature-stress irradiation devices can only conduct rough load, and more critically, the device cannot measure the deformation of the material during the irradiation process
