Abstract

The invention belongs to the technical field of reactor material irradiation performances and discloses a metallic material irradiation device used in a reactor. The device comprises a packaging casing, a sample casing, a core shaft, a base and a pressing cover, wherein the packaging casing is positioned above the sample casing and is connected with the sample casing by a clamping groove; the sample casing comprises one or more sub-casings; the inner side of each sub-casing is provided with one or more isolating devices which can be used for placing standard samples. The device disclosed by the invention has the characteristics that the temperature distribution is uniform and a plurality of samples can be placed.

Description

technical field [0001] The invention belongs to the technical field of reactor material irradiation performance research, and in particular relates to a metal material irradiation device used in a reactor. Background technique [0002] Each component used in the reactor must be tested for its constituent materials for radiation resistance before the design is completed. In order to test the radiation resistance, different metal materials are usually made into various standard samples and sent into the reactor for irradiation. test. [0003] The irradiation test in the reactor also has the following characteristics: (1) The cycle is long. Long-term high-temperature irradiation in the reactor requires that the irradiation device and the sample heating system have high reliability in the long-term use in the reactor. About 6×10 19 n / cm 2 , It takes about 1.5 years for the in-core irradiation time to reach the corresponding irradiation dose, so the irradiation device is requ...
