Ventilation scheme analysis and optimization of a disposal cavern for low and intermediate level radioactive waste

Presents a ventilation scheme design of a disposal cavern for low and intermediate level radioactive waste. Using CFD numerical simulation method, analyses and verifies the natural ventilation condition. The results show that the natural ventilation condition is reasonable and effective, and can meet the environmental requirements for the disposal cavern within a certain period of time. Proposes a method to optimize the setting of ventilation shafts using perennial natural wind in the project location, and determines the specific optimization measures in view of the CFD numerical simulation result.
