核通风用箱体容许泄漏率的确定方法

Way for determining the allowable leakage of housings used in nuclear ventilation

要目前国内对核通风用箱体容许泄漏率没有统一要求,根据ASME新标准中对风管容许泄漏率的确定方法,推导出箱体容许泄漏率的具体计算公式,经示例验证,结果更为科学严谨,因此建议相关工程设计人员按此计算方法,统一箱体容许泄漏率的确定方法,应用于工程设计。

Now in domestic ,there are some different leakage requirements of housings used in nuclear ventilation, according to ASME newly revised standards, which suggest the way for determination of the allowable leakage for ductwork, deriving special formulas for housings allowable leakage, thus verified by an example, result shows more scientific and realistic, therefore suggest some relevant engineering designers unifying the leakage requirements of housings by the way to determine, and applying it to projects design.
