NP 033-11 PDF

Full title and description

NP-033-11 — "Общие положения обеспечения безопасности исследовательских ядерных установок" / "General safety provisions of research nuclear installations". This federal norms-and-rules document sets out terms, principles and general requirements for ensuring safety at research nuclear installations (design, construction, operation and decommissioning), including reactor facilities, critical and subcritical test stands and other research nuclear sources of potential radiation exposure.

Abstract

NP-033-11 provides consolidated safety principles for research nuclear installations: definitions and classification, design and construction requirements, requirements for operation and maintenance, classification of systems and elements by safety significance, measures for radiation protection of personnel and the public, emergency preparedness and decommissioning guidance. It was developed on the basis of Russian legal acts and in consideration of IAEA recommendations.

Scope

Applies to research nuclear installations at all stages — design, siting, construction, commissioning, operation and decommissioning. The document sets general and specific requirements for reactor-type research facilities, critical and subcritical stands and subcritical nuclear assemblies that may produce radiation exposures to workers, the public and the environment. NP-033-11 is intended to be used alongside more specialised NP rules that cover specific reactor types, experimental stands and safety systems.

Key topics and requirements

• Definitions and terminology specific to research nuclear installations.
• Fundamental safety principles and objectives for design and operation.
• Classification of systems, structures and components by safety significance.
• Design, siting and construction requirements addressing normal operation and anticipated operational occurrences.
• Operational requirements including commissioning, operating procedures, maintenance, testing and administrative controls.
• Requirements for radiation protection of personnel, population and environment; limits and monitoring.
• Emergency preparedness, response measures and protective actions for incidents and accidents.
• Decommissioning principles and requirements for removal from service and safe dismantling.
• Requirements and examples of operational procedures to be included in technological regulations for research installations.

Typical use and users

Primary users: research reactor operators, designers and constructors of experimental nuclear facilities, safety engineers, regulatory and inspection bodies, equipment manufacturers supplying safety-class components for research installations, and organisations preparing safety analysis reports and operational procedures. The document is used as a regulatory framework to develop site- and facility-specific safety documentation and technical requirements.

Related standards

Closely related NP rules and documents include the previous edition NP-033-01 (replaced by NP-033-11), NP-009 series (rules for research reactors), NP-008 (critical test stands), NP-028 (decommissioning of research installations) and other NP-series safety rules addressing classification, instrumentation, emergency preparedness and radiation protection. These documents form the NP regulatory family used by Rostechnadzor for research nuclear safety.
