The traditional QRA is generally comprised of five tasks:<br />

传 统 的 定 量 风 险 评 估 一 般 包 括 五 项 任 务 :<br />

1. systems identification, 系 统 辨 识<br />

2. hazards identification, 危 害 识 别<br />

3. probability assessment, 概 率 评 估<br />

4. consequence analysis, 后 果 分 析<br />

5. risk results. 风 险 结 果<br />

The systems definition, hazard identification and consequence analysis are<br />

integrally linked.<br />

Hazard identification in an RBI analysis generally focuses on identifiable<br />

failure mechanisms in the equipment (inspectable causes) but does not<br />

explicitly deal with other potential failure scenarios resulting from events<br />

such as power failures or human errors. A QRA deals with total risk, not just<br />

risk associated with equipment damage. 分 析 一 般 集 中 在 识 别 设 备 失 效 机 理 .<br />

QRA 针 对 总 风 险 , 不 仅 仅 与 设 备 损 坏 相 关 的 风 险<br />
