Full title and description

GOST 31901-2013 — Pipeline valves for nuclear stations. General specifications (Russian title: «Арматура трубопроводная для атомных станций. Общие технические условия»). This interstate (GOST) standard establishes general technical requirements for pipeline valves and their actuators used at nuclear power plants, nuclear vessels and other facilities using atomic energy.

Abstract

GOST 31901-2013 sets out general design, material, manufacture, testing, marking, packaging, transport, storage, operation and disposal requirements for pipeline valves and associated actuators intended for use in nuclear power installations, floating nuclear power units and other facilities where atomic energy is applied. The standard is intended to ensure safety, reliability and interchangeability of valves used in nuclear applications.

Scope

The standard applies to pipeline valves and their drive devices intended for nuclear power plants, nuclear ships and floating structures (including shipboard floating power units) and other facilities using atomic energy. It establishes general technical requirements that must be met during design, manufacture, acceptance, testing, transportation, storage, operation, maintenance, repair and disposal of such valves and actuators.

Key topics and requirements

• Definitions, classification and designation of pipeline valves for nuclear applications.
• Technical requirements for materials, design and manufacture to ensure mechanical integrity, leak tightness and resistance to operational loads and environmental conditions.
• Safety-related requirements, including provisions for fail-safe design, position indication and interfaces with control/monitoring systems.
• Testing and inspection: type tests, acceptance tests, leak tests, pressure tests, functional and endurance tests for valve and actuator assemblies.
• Quality assurance, documentation, marking, traceability and requirements for supplier technical documentation (drawings, certificates, test reports).
• Handling, packaging, transportation and storage conditions specific to nuclear-industry components.

Typical use and users

Used by designers, manufacturers and suppliers of pipeline valves and actuators for nuclear power plants, nuclear vessel builders, plant operators, quality and inspection bodies, procurement specialists, and regulatory authorities involved in nuclear facility equipment qualification and acceptance.
