核电工程施工临时通风设计研究

Research on Temporary Ventilation System Design in Nuclear Power Plant Construction

为确保核电过程中的生产安全,改善从业人员作业环境,预防职业病的发生,根据AP1000核电建设的作业条件和空间环境特点,探讨了临时通风系统设计原则和步骤,基于流体力学理论,建立了通风系统设计的数学模型。并以优化通风为目的,提出了分区域与分阶段通风相结合、系统通风与局部通风相结合、机械通风和自然通风相结合的通风方案。现场应用表明,该通风系统能够有效排除烟尘、改善空气质量、满足施工现场HSE(health,safety and environment)管理要求,对保证核电工程安全和质量具有重要意义。

To ensure safety production during nuclear power construction, improve workers＇ activity environment and prevent occupation illness, temporary ventilation system is discussed from view of design rules and procedures and the ventilation design model is erected based on hydromechanies theory. To optimize ventilation effect, ventilation schemes combined with area ＆ stage, system ＆ local, and mechanical ＆ natural ventilation is advanced. Field application shows that this ventilation system can effectively eliminate dust, improve air condition, and satisfy HSE management requirements. Thus it is important to promise nuclear power project safety and quality.
