Abstract: Vacuum technology is widely used in the field of nuclear industry. When dealing with vacuum devices containing radioactive and toxic and hazardous substances, it is particularly prudent to operate and maintain them, which usually need to be placed in a hot cell. In order to realize the effective operation and easy maintenance of the vacuum device, and improve the reliability of the vacuum device, it is particularly important to carry out adaptive design. Based on the basic background of the hot cell, this paper introduces the design points of the key elements such as the automatic sliding door of the vacuum equipment that can be operated remotely, the vacuum system arranged remotely outside the hot cell, the metal vacuum sealing, the motor structure that can be replaced remotely, and the selection of radiation-resistant materials, which provides scientific basis and practical guidance for the design of similar vacuum devices.

Key words: hot cell, vacuum, vacuum equipment, radiation
