FLUID TREATMENT SYSTEM

摘要

The present disclosure provides, in an embodiment, a system for treating a contaminated fluid. The system may include multiple shielded modules in fluid communication with one another. Each module of the system of the present disclosure may include an inner pressure vessel designed to accommodate a treatment medium, the treatment medium being selected to remove radioactive contaminants from a fluid passed through the pressure vessel. The module may also include an outer shield vessel surrounding the pressure vessel and designed to attenuate the radiation from the radioactive contaminants accumulated by the treatment medium in the pressure vessel and facilitate ease of handling and storage of the module together with the contaminated treatment medium. Finally, an annular region may be defined between the pressure vessel and the shield vessel for passing a cooling medium therethrough to remove decay heat from the radioactive contaminants accumulated in the pressure vessel.
