NP 006-16 PDF

Full title and description

NP-006-16 — Federal norms and rules in the field of use of atomic energy: "Requirements to the contents of the safety analysis report for a nuclear power plant with VVER‑type reactor". This document sets mandatory requirements for the form and technical content of the safety (justification) report (safety analysis report, SAR/OOБ АС) that must accompany design, licensing and major modification documentation for VVER nuclear power units in the Russian Federation.

Abstract

NP-006-16 defines the required structure, scopes of analysis and documentary evidence for a complete safety analysis report for VVER‑type reactor units. It specifies what technical chapters and supporting analyses (deterministic and probabilistic safety analyses, thermal‑hydraulics, neutronics, fuel behaviour, instrumentation and control, seismic and external hazards, human factors, ageing management, and emergency planning information) must be presented, and the expectations for justification, references and traceability of results used in licensing and regulatory review. The document was prepared as a federal norm/rule and approved by the competent Russian supervisory authority.

Scope

NP‑006‑16 applies to safety justification documentation for nuclear power plant units with VVER (water‑water energetic reactor) type reactors. It prescribes the mandatory contents and presentation of the safety analysis report that must be submitted for design approval, construction permit, commissioning and significant design changes, including descriptive, analytical and experimental/technical evidence required to demonstrate compliance with applicable national safety criteria and regulatory requirements. The scope covers both deterministic analyses (design‑basis events, single‑ and multiple‑failure analyses, system descriptions) and probabilistic safety assessment inputs where required, as well as requirements for organization of information, references and supplementary appendices.

Key topics and requirements

• Required SAR structure and chapter-level content (introduction, plant description, design bases, reactor core and fuel, systems important to safety, instrumentation and control, radiation protection, etc.).
• Deterministic safety analyses for normal operation, anticipated operational occurrences and design‑basis accidents, including acceptance criteria and margins.
• Severe accident and beyond‑design‑basis considerations — required analyses and plant features to be documented.
• Probabilistic safety assessment (PSA) inputs and use in the SAR where required, including treatment of initiating events and core damage frequency considerations.
• External hazards (seismic, flooding, extreme weather, external human actions) and their influence on equipment, structures and safety functions.
• Ageing management, inspection and maintenance programmes, testing and commissioning evidence relevant to long‑term safety.
• Human factors, operating procedures, personnel training and organisational measures that affect safety.
• Requirements for references, traceability, experimental/analytical validation, and presentation of uncertainties and conservative assumptions.

Typical use and users

Primary users are license applicants, plant designers and engineering organisations preparing or updating a safety analysis report for VVER units, as well as regulatory reviewers and technical experts evaluating applications for design approval, construction, commissioning and major modifications. Additional users include reactor vendors, safety consultants, and organisations responsible for plant operation, ageing management and emergency preparedness.

Related standards

NP‑006‑16 is part of the NP series of federal rules and regulations addressing nuclear safety in the Russian Federation (examples: NP‑001‑15, NP‑002‑15, NP‑005‑16, NP‑010‑16, etc.). It should be used together with other NP documents, national legislation on the use of atomic energy and relevant international standards where adopted.

FAQ

Q: What is this standard?

A: NP‑006‑16 is a Russian federal norm/rule that specifies the required content and organisation of the safety analysis report (SAR) for nuclear power plant units with VVER‑type reactors; it is issued as part of the NP series of regulatory documents.

Q: What does it cover?

A: It covers the chapters, analyses and documentary evidence that must be presented in an SAR (design description, design bases, systems important to safety, deterministic and probabilistic analyses, external hazards, human factors, ageing management, and related technical justification and validation). The document sets expectations for the level of detail, references and traceability required by the regulator.

Q: Who typically uses it?

A: License applicants, plant designers, safety analysts, vendors and consultants preparing SARs for VVER units, and regulatory reviewers who assess those SARs. Operators and asset managers also use the standard when preparing safety documentation for modifications or major safety cases.

Q: Is it current or superseded?

A: NP‑006‑16 was approved by order (No. 53) dated 13 February 2017 and published 23 May 2017; commercial distributors and regulatory information list it as the active NP document for SAR content requirements for VVER units. Users should verify with the national regulator for any later amendments or superseding documents before relying on it for formal submissions.

Q: Is it part of a series?

A: Yes — NP‑006‑16 belongs to the NP (federal norms and rules) series governing nuclear safety in Russia; many NP documents address complementary topics (overall safety rules, waste management, emergency procedures, systems and components requirements) and are intended to be used together.

Q: What are the key keywords?

A: Safety analysis report (SAR), VVER, nuclear safety, deterministic analysis, probabilistic safety assessment (PSA), design basis, severe accident analysis, Rostekhnadzor, NP series, Обоснование безопасности.
