放射性废物厂房负压取值的探讨

Discussion on negative pressure value of radwaste building

为了减少放射性物质向环境的不可控排放,放射性废物厂房的通风系统正常运行时需维持负压。分析了影响放射性废物厂房负压的3种主要因素:基础负压、室外风压和热压,并给出了合理的计算方法。结合工程实例,计算在3种因素综合作用下,放射性废物厂房需保证的合理负压值,并提出了设计建议。

In order to reduce the uncontrollable emission of radioactive materials, keeps the ventilation system of the radwaste building under negative pressure during routine operation. Analyses three influence factors of basal negative pressure, outdoor wind pressure and stack effect pressure, and presents a reasonable calculation method. Combined with an engineering practice, calculates a reasonable negative pressure value of radwaste building under the combination of three factors, and provides design suggestions.
