Description

Technical Field

[0001] The present invention belongs to the field of unmanned mechanical feeding, and in particular relates to a remote control feeding platform and method for a fusion reactor hot chamber detritium removal system. Background Art

[0002] The hot cell of a fusion reactor is responsible for the temporary storage, maintenance, renovation and decommissioning of the internal components and equipment of the tokamak device. Since the core components or equipment may be activated by neutron radiation, or contaminated by tritium or beryllium, or may be attached with radioactive dust, all maintenance operations within the strictly controlled area of ​​the hot cell (total radiation dose E>100mSv, surface dose H>2.5mSv / h) must be completed by a remote control robot system. The most concerned fusion reaction is deuterium-tritium fusion, which has a high reaction cross section and is the easiest to achieve engineering application. However, tritium, as a fusion fuel, is an artificial radioactive nuclide that easily penetrates and is retained in the surrounding materials. After the core components such as the tritium-producing blanket are shut down, the amount of tritium retained inside the material is relatively high. Therefore, it is necessary to provide a remote control feeding platform and method for the detritium removal system of a fusion reactor hot cell to solve the shortcomings of the existing technology.
