Deduces the relationship between the purification coefficient of the ventilation system and the leakage rate and the purification coefficient of the filter material. Considers that small leakage of nuclear ventilation system will greatly reduce the purification capacity of the system. Taking a nuclear power plant as an example, analyses the leakage causes of the ventilation system and puts forward some measures to reduce the leakage rate.
