11.4 Volume of Fluid Released 流 体 释 放 体 积<br />

In most consequence evaluations, a key element in determining the magnitude<br />

of the consequence is the volume of fluid released. The volume released is<br />

typically derived from a combination of the following items below.<br />

大 多 数 故 障 结 果 的 评 估 , 在 确 定 故 障 结 果 的 幅 度 的 一 个 关 键 因 素 是 流 体 释 放 的 体 积<br />

a) Volume of Fluid Available for Release—Volume of fluid in the piece of<br />

equipment and connected equipment items. In theory, this is the amount of<br />

fluid between isolation valves that can be quickly closed .<br />

可 以 快 速 关 闭 隔 离 阀 之 间 的 流 体 量<br />

b) Failure mode. 失 效 模 式<br />

c) Leak rate. 泄 漏 率<br />

d) Detection and isolation time. 检 测 和 隔 离 时 间<br />
