标准摘要
[中文适用范围]: 本文件为管理核电厂(NPP)系统安全与网络安全之间的相互作用提供了一个框架,考虑了当前SC 45A标准对这些问题的处理以及核I&C可编程数字系统的特殊性。 本文件建立了以下要求和指导: - 将网络安全规定整合到主要为安全设计的核I&C架构和系统中; - 避免安全与网络安全规定之间的潜在冲突; - 帮助识别和利用安全与网络安全之间的潜在协同效应。 本文件适用于设计新核电厂或现代化现有核电厂,贯穿I&C可编程数字系统的整个生命周期。也适用于评估现有电厂安全与网络安全之间的协调性。可能也适用于其他类型的核设施。 本文件涉及对安全重要的I&C可编程数字系统和不重要的I&C可编程数字系统。不涉及专门用于现场物理安全、房间访问控制和现场安全监视的可编程数字系统。 本文件仅限于核电厂I&C可编程数字系统,包括其现场维护和配置工具。 [外文原描述]: IEC 62859:2016 provides a framework to manage the interactions between safety and cybersecurity for nuclear power plant (NPP) systems, taking into account current IEC standards addressing these issues and the specifics of nuclear I&C programmable digital systems. This standard establishes requirements and guidance to: - integrate cybersecurity provisions in nuclear I&C architectures and systems, which are fundamentally tailored for safety; - avoid potential conflicts between safety and cybersecurity provisions; - aid the identification and the leveraging of the potential synergies between safety and cybersecurity.
