Abstract:

Presents the ventilation system for a nuclear facilities decommissioning and waste control testing center, including system composition, air rate calculation, equipment and piping setting, ventilation control system and exhaust air emission. Elaborates the ventilation systems of the laboratory room with the fume hood, the exhaust of the fume hood and the air supply system of the variable air volume system. Through an accurate and rapid control system to control the ventilation system, so as to maintain a certain pressure difference between each partition, control and limit the diffusion of radioactive substances, and makes sure that the air flows from the low polluted area to the high polluted area, which ensures a safety and comfort production and living environment.

Keywords:ventilationsystem,controlsystem,radioactivitysubstance,fumehood,exhaustairrate
