RB 089-14 PDF

Full title and description

RB 089-14 — Safety guide on nuclear energy use: Unified control procedures of basic materials (semi-finished products), welded joints and build-ups of equipment and pipelines of nuclear energy plants. Visual and measuring testing. Provides unified methods and recommended procedures for visual and dimensional (measuring) inspection and acceptance of materials, welds and overlaying used in nuclear power plant equipment and piping.

Abstract

RB 089-14 sets out recommended practices for visual and measuring control of base materials, semi-finished products, welded joints and claddings used in nuclear power installations. The document defines inspection objectives, general inspection methods, acceptance criteria for surface and dimensional defects, documentation and recording requirements, and responsibilities for inspection personnel. The guidance is intended to ensure consistent detection and evaluation of surface discontinuities and dimensional non-conformities that could affect the integrity and safety of nuclear plant components.

Scope

This guide covers visual (surface) and measuring (dimensional) control of basic materials, semi-finished products, welded joints and applied build-ups (overlaying) for equipment and pipelines of nuclear power plants. It provides recommended procedures for inspection before and after fabrication, during erection and commissioning, and for in-service checks where applicable. The guidance focuses on detection, classification and evaluation of surface defects and dimensional non-conformities that may affect mechanical integrity or fitness-for-service.

Key topics and requirements

• Definitions and terminology for visual and measuring inspection in the nuclear context.
• General principles for inspection planning, sampling and inspection frequency.
• Visual inspection methods: lighting, surface preparation, inspection zones, defect identification (cracks, laminations, laps, handling marks, cavities, inclusions, etc.).
• Measuring control: dimensional checks, tolerances, fit-up, geometric requirements and use of measuring instruments.
• Acceptance criteria and classification of surface discontinuities and dimensional deviations.
• Requirements for inspection records, reporting, traceability and marking of inspected items.
• Personnel qualifications, responsibilities and minimum competency for visual/measuring inspectors.
• Actions for non-conformities: disposition, repair/repair welding, re-inspection and documentation.

Typical use and users

Primary users are nuclear power plant designers, fabricators, welding and inspection contractors, QA/QC engineers, NDT and visual inspection personnel, plant operators and regulatory compliance teams. The guide is used during procurement, fabrication, welding operations, equipment acceptance, erection, commissioning and periodic or special inspections in service.

Related standards

RB 089-14 was published as modernized unified guidance and superseded earlier national documents on the same topic. It replaces or updates provisions from older GOST / PNAE guidance on visual and measuring control (for example the prior PNAE/GOST series on inspection). Note: RB 089-14 itself was later withdrawn; consult the current national regulatory catalogue for the up-to-date normative documents that currently apply in place of RB 089-14.

FAQ

Q: What is this standard?

A: RB 089-14 is a national safety guide issued in 2014 that provides unified methods for visual and measuring inspection of materials, welded joints and build-ups for nuclear power plant equipment and pipelines.

Q: What does it cover?

A: It covers procedures, acceptance criteria and documentation practices for visual (surface) and dimensional (measuring) control of base materials, semi-finished products, welds and overlaying used in nuclear installations, including inspection planning and inspector qualifications.

Q: Who typically uses it?

A: Nuclear plant operators, designers, fabricators, welding and inspection contractors, QA/QC engineers and inspection personnel responsible for material and weld quality in nuclear projects.

Q: Is it current or superseded?

A: RB 089-14 was introduced on 6 June 2014 but was withdrawn and made not effective as of 1 March 2019 by a regulatory order. It is not the current active regulatory guidance; users should consult the latest national regulatory database or the competent supervisory authority for the in-force replacement documents.

Q: Is it part of a series?

A: Yes — RB 089-14 is part of the "Руководства по безопасности" (safety guides) family addressing nuclear safety and inspection methods. It updates earlier GOST/PNAE guidance on unified control methods and is linked conceptually to other RB documents governing materials, welding and quality assurance in nuclear facilities.
