Name in Russian:
ГОСТ Р МЭК 61500-2021
Instrumentation and control systems important to safety of a nuclear power plant. Data communication in systems performing category A functions
Full title and description
ГОСТ Р МЭК 61500-2021 — Системы контроля и управления, важные для безопасности атомной станции. Передача данных в системах, выполняющих функции категории A. (Instrumentation and control systems important to safety of a nuclear power plant — Data communication in systems performing category A functions).
Abstract
This national adoption (GOST R) establishes functional and interface requirements for on‑line data communication used within safety‑important (category A) instrumentation & control systems at nuclear power plants. It defines categorization of communication functions, interface requirements between category A equipment and other systems, and requirements for reliability, separation/isolation and qualification of communication links. The document excludes general voice/telephony/public communication methods and internal processor memory/control‑logic connections. The GOST R text is identical (IDT) to the referenced international edition.

Scope
The standard applies to data communication within plant instrumentation & control safety systems that perform category A functions. It covers on‑line data links and interfaces of category A equipment with other systems (including B and C category systems and non‑safety functions) where such communication affects safety performance. It does not cover voice/telephone/radio/public address/fax/email communications, nor the internal data paths inside processors, memory or control logic. The document sets requirements by reference to established IEC nuclear I&C standards and requires categorization of communication functions per IEC 61226.
Key topics and requirements
- Functional requirements for data communication used by category A safety systems.
- Interface requirements between category A equipment and other plant systems (B, C and non‑safety systems).
- Requirements for physical separation, isolation and functional independence of safety communication channels.
- Reliability, fault‑tolerance and failure‑mode considerations for communication functions.
- Qualification and environmental/seismic considerations for communication equipment and links (references to equipment qualification standards).
- Maintenance, modification control and documentation requirements for communication implementations.
- Categorization of communication functions in accordance with IEC 61226 and related IEC nuclear I&C guidance (IEC 61513/IEC 60880/IEC 60987).
Typical use and users
Used by nuclear power plant I&C engineers, system architects, equipment suppliers, safety assessors, regulator and licensing bodies, QA/verification teams, and certification/qualification laboratories when designing, procuring, implementing or assessing data communication for safety‑important systems. It is referenced in procurement specifications, design reviews, safety cases and qualification programs.
