水冷式核电厂（NPP）防火分区的论证方法

[中文适用范围]： 提供确定室内防火屏障热效应的指南；基于标准测试特性评估整体性能；评估额外测试需求以验证解决方案的稳健性。 详细说明适用标准、数值工具的验证和确认（V&V），以及防火实验室的预期资质。 讨论方法应用的局限性和范围。 [外文原描述]： The document provides: — guidelines for determining the thermal effects to consider on fire barriers inside a given room; — guidelines for determining the global performance of the fire barriers based on standard test characterization; — guidelines for assessing the need for additional tests to verify the robustness of the solution. Requirements of applicable standards, numerical tools validation and verification (V&V), and the expected qualification of fire resistance laboratories are detailed. The limitations of the method's applicability and scope are discussed. The purpose and justification of this document is to describe a new methodology for the verification of the efficiency of fire barriers, which is initially based on a standardized fire resistance test. The significance of this work relates to the fact that the present methodology will enhance the level of safety by providing more realism to hazards analysis in combination with standardized test data. It completes the standard ISO-fire rating required for justifying the performance. The most relevant benefit of this method concerns the determination of the global performance of a barrier in a fire of extended duration compared to the classification given by the ISO-fire rating.
