Research on Simulation of Hot Cell Ventilation Control System Based on COMSOL and MATLAB

The hot cell is the core equipment in the nuclear chemical treatment process. Before the construction of hot cell, it is often necessary to carry out simulation verification of the ventilation control strategy to ensure the effectiveness of the control strategy. To solve this problem, COMSOL is used to build the simulation model of the hot cell to simulate the ventilation condition of the real hot cell, and the simulation process is controlled online with MATLAB. Firstly, the boundary conditions and structure of the hot cell are analyzed, and the multi-physical field model is established. Then, the principle and implementation method of data transmission and sampling control in the co-simulation are studied. Finally, the co-simulation between COMSOL and MATLAB is implemented, and the simulation results are drawn in MATLAB. The simulation results verify the effectiveness of the ventilation control strategy under typical working conditions, which has certain reference for the design of the actual hot cell ventilation control system.
