NP 089-15 PDF

Full title and description

NP-089-15 — Federal norms and rules in the field of atomic energy: "Rules for design (arrangement) and safe operation of equipment and pipelines of nuclear power installations" (Russian: НП-089-15 "Правила устройства и безопасной эксплуатации оборудования и трубопроводов атомных энергетических установок"). This document sets mandatory technical and safety requirements for pressure-retaining equipment and piping used at Russian nuclear power and research installations.

Abstract

NP-089-15 prescribes requirements for the design, manufacture, assembly, testing, inspection, commissioning and operation of equipment and pipelines that operate under excess, hydrostatic or vacuum gauge pressure and that are assigned to groups A, B or C. It defines classification, material and fabrication rules, non‑destructive examination, pressure testing, registration and lifecycle management obligations necessary to ensure nuclear and industrial safety of such systems.

Scope

These Rules apply to equipment and pipelines of atomic energy installations that operate under overpressure, hydrostatic pressure or vacuum (pressure‑retaining items) and that are allocated to groups A, B and C according to the classification criteria within the document. The Rules cover design and strength assessment, selection of materials, requirements for manufacture and fabrication (including welding), assembly and installation, non‑destructive testing and pressure testing, acceptance criteria, documentation and registration, operation, inspection and maintenance, repair and end‑of‑life management to ensure nuclear and industrial safety.

Key topics and requirements

• Classification of equipment and piping into groups A, B, C according to safety significance and failure consequence.
• Design principles and strength calculations for pressure‑retaining parts (allowable stresses, safety factors, loads considered).
• Materials selection and approval, including base metals, weld consumables and restrictions for nuclear service.
• Fabrication and welding rules, welder/procedure qualification and manufacturing quality control.
• Non‑destructive examination (NDE) methods and acceptance criteria (radiography, UT, PT, MT, visual inspection).
• Hydrostatic and pneumatic testing, leak testing and post‑repair requalification procedures.
• Documentation, marking, equipment registration and traceability requirements for items placed in service.
• Operation, inspection intervals, in‑service monitoring, fitness‑for‑service and lifecycle/resource management.
• Repair, modification and requalification processes; criteria for removal from service.
• Requirements to ensure quality assurance, personnel competence and radiation/safety provisions where applicable.

Typical use and users

Primary users include nuclear plant designers and engineering organizations, equipment and pipework manufacturers and fabricators, construction and installation contractors, plant operating organizations, regulatory inspectors, quality assurance and in‑service inspection teams, and material/welding specialists. The document is used during design specification, procurement, fabrication, commissioning, regulatory compliance checks and lifecycle management of pressure equipment and piping at nuclear installations.

Related standards

NP-089-15 is part of the Russian system of federal norms and rules for atomic energy and is used alongside related documents such as NP-096-15 (requirements for managing equipment and pipeline service life), earlier PNAE/strength calculation norms (for example PNAE G‑7 series) and applicable GOST standards for materials, welding and testing. It also interrelates with other NP-series federal rules and regulatory orders issued by Rostekhnadzor.

FAQ

Q: What is this standard?

A: NP-089-15 is a Russian federal norm and rule that establishes mandatory technical and safety requirements for the arrangement, design, manufacture, testing and safe operation of pressure‑retaining equipment and pipelines at nuclear power and research installations.

Q: What does it cover?

A: It covers classification, mechanical design and strength, materials, fabrication (including welding), testing and inspection (NDE, pressure tests), documentation and registration, operation and maintenance, repair and lifecycle management of equipment and piping that operate under pressure and are assigned to safety groups A, B or C.

Q: Who typically uses it?

A: Designers, fabricators, manufacturers of pressure equipment, installation contractors, plant operators, regulatory bodies and inspectors, QA and NDE specialists working in the nuclear sector use NP-089-15 to demonstrate compliance and to set technical requirements for components and systems.

Q: Is it current or superseded?

A: NP-089-15 is an active federal rule. It was adopted in late 2015 and entered into force on 23 February 2016; it has been amended by later Rostekhnadzor orders (notably orders of 17 Jan 2017 and 19 Nov 2019 with amendments coming into force 6 Jan 2020). Users should check for any further amendments or newer related NP documents before applying the rule.

Q: Is it part of a series?

A: Yes — NP-089-15 is part of the NP series of federal norms and rules in the field of atomic energy; it complements other NP documents (for example NP-096-15 on equipment and pipeline resource management) and national technical standards (PNAE, GOST) relevant to nuclear equipment design and testing.
