Research Status and Progress of Mobile Hot Cells

Abstract: The mobile hot cell is a radioactive material handling facility designed for integrated transport and rapid reassembly at target sites. Through modular design, it addresses the poor flexibility issues associated with stationary hot cells. With the development of the nuclear industry, the demand for radioactive material handling and conditioning operations in nuclear facilities continues to grow. While traditional stationary hot cells are technologically mature, but it face cost limitaions . As an innovative nuclear facility, mobile hot cells offer advantages such as portability, dismountability, high mobility, and cost efficiency, enabling rapid responses to inspection and processing needs in nuclear facilities.
This paper provides a review of the developmental history and iterative evolution of mobile hot cell facilities with diverse structures worldwide. The current research status regarding the shielding methods, viewing windows, transport containers, and other components of mobile hot cells is examined. The article points out that the future development trends for mobile hot cells include the sealed interconnection of multiple modules, highly integrated efficient shielding, and intelligent operation and maintenance.
