Fire protection design for ventilation system of nuclear power plants

Analyses the design of fire protection zone for nuclear power plants, and compares with that in the civil buildings. Presents the fire protection design of ventilation system for each workshop of nuclear power plants in detail and the application of active fire protection and passive fire protection measures. Analyses the design of the smoke control and extraction system and pressurization supply system in detail. It is proved that the fire protection design can meet the requirements of radioactive zone and single failure rule, so the design is safety for nuclear power plants.
