Full title and description

RB 102-15 — Recommendations to the Structure and Content of BDBA (including Severe Accidents) Management Guideline. (Русское название: РБ 102-15 — Рекомендации к структуре и содержанию руководства по управлению запроектными авариями, в том числе тяжелыми авариями.)

Abstract

Guidance issued for development and structuring of plant-level management guidelines for beyond‑design‑basis accidents (BDBA), including severe accident phases. The document defines recommended structure, operational and informational sections, diagnostic criteria for safety functions, roles and responsibilities, example strategies for severe damage mitigation, and auxiliary assessment tools to support decision‑making during BDBA at nuclear power plants.

Scope

This safety guideline provides recommended structure and content for a plant’s BDBA management guideline (РУЗА) covering: criteria and triggers for application, the main (operational) instruction set including diagnostic instructions and task‑level instructions (e.g., restoration/maintenance of safety functions), the informational/support annexes (phenomenology, calculation bases, auxiliary assessment tools), roles and organisational arrangements for accident management, and example decision‑making strategies for severe core damage scenarios at nuclear power plants. It is intended for use by operating organisations and design organisations developing BDBA management documentation.

Key topics and requirements

• Recommended document structure: general provisions, operational section (main instruction and task instructions), and reference/informational annexes.
• Clear diagnostic criteria for safety‑function states and associated instruction applicability.
• Definition of roles, responsibilities and organisational structure for BDBA management and emergency command (including support groups and external technical centres).
• Guidance on writing unambiguous, easy‑to‑use instructions to avoid misinterpretation under stress.
• Sample strategies for managing severe core damage, including water supply strategies, hydrogen management, and function‑restoration tasks.
• Auxiliary assessment tools and calculation examples to support operational decisions (e.g., required flows to refill core, criteria for using additional makeup systems).
• Annexes with terminology, human‑factor considerations, examples of operator errors, and sample content tailored to VVER‑type units (example content provided).

Typical use and users

Primary users are nuclear power plant operating staff, emergency/accident management teams, procedure writers, safety engineers, and design organisations preparing or updating BDBA (beyond‑design‑basis accident) management guidelines. Secondary users include national/regulatory safety analysts, trainers, and external technical support centres involved in plant emergency support. The guidance is used to structure procedures, define diagnostic criteria, prepare training scenarios, and support regulatory reviews.

Related standards

Related regulatory and guidance documents cover NPP emergency preparedness, design‑basis accident procedures, severe accident management guidelines, and other Rosatom / Rostekhnadzor safety documents. RB 102-15 is presented as complementary guidance to plant‑specific emergency procedures and severe accident management guidelines used for different reactor types (examples and appendices reference VVER units). Users should consult national regulatory requirements and reactor‑specific SAMG/EMG documents when implementing RB 102-15 recommendations.
