NP 068-05 PDF

Full title and description

NP 068-05 — Pipeline valves for nuclear plants. General technical requirements. Federal rules and regulations establishing design, manufacture, testing, transportation, storage, installation and operational requirements for pipeline (process) valves used at nuclear power plants.

Abstract

This regulatory document (NP-068-05) specifies mandatory technical and quality requirements for pipeline valves intended for use in nuclear power plants, including requirements for materials, design, testing (acceptance, qualification and service-life), marking, packaging, handling, storage and recordkeeping. It was prepared to harmonize valve design and verification practices for safety‑classified systems in Russian nuclear facilities and to support consistent procurement, manufacturing and in‑service assessment of valves used in reactor and balance‑of‑plant systems.

Scope

NP-068-05 applies to pipeline valves manufactured for and used in nuclear power plants. The document sets requirements that cover valve design (including materials and structural items), manufacturing and quality control, testing (type, acceptance, qualification and service-life tests), acceptance criteria, marking, transportation, storage, installation and operation. It is intended for use by designers, manufacturers, test laboratories, plant operators and regulatory bodies involved with safety-classified valve equipment for nuclear facilities.

Key topics and requirements

• Definitions and classification of pipeline valves by function and safety class.
• Design and material requirements to ensure functional reliability under design-basis conditions.
• Manufacturing and quality assurance procedures, including documentation and traceability.
• Acceptance testing, prototype and qualification testing programs, and service-life testing protocols.
• Requirements for cavitation, flow (throughput coefficient) determination, and control-valve characteristic verification where applicable.
• Requirements for marking, packaging, transportation and storage to preserve valve integrity prior to installation.
• Installation, operation and maintenance recordkeeping and in-service verification requirements.

Typical use and users

Primary users are nuclear plant designers, engineering contractors, valve manufacturers and fabricators, quality and test laboratories, procurement and acceptance engineers, regulatory inspectors and utility plant operations/maintenance departments responsible for safety‑classified piping systems. The document is used during specification, procurement, manufacturing, qualification testing and in‑service surveillance of valves for reactor coolant systems, auxiliary systems and other nuclear plant piping.
