SAFE OPERATIONS
9.1. NUCLEAR AND RADIATION SAFETY;
OCCUPATIONAL SAFETY AND HEALTH
Key results in 2022:
There were no events rated at level 1 or higher on the INES scale.
The injury frequency rate and the lost time injury frequency rate (LTIFR) stood at 0.25 and 0.11 respectively.
Individual radiation risk was calculated for 65,729 people using the IRAW system.
GRI 3-3 The Company's main objective in the area of nuclear and radiation safety is to ensure ongoing accident-
free operation of existing nuclear facilities and other facilities posing nuclear and radiation hazards, safely
manage radioactive waste, improve the culture of safe operation of nuclear facilities, and implement
modern safety management systems.
Measures aimed at ensuring nuclear and radiation safety are a priority for the Company and its key
stakeholders. All of the Company's organisations are directly involved in ensuring nuclear and radiation
safety. Key organisations include JSC Atomredmetzoloto, JSC Atomenergomash, JSC Rosenergoatom,
JSC TVEL and JSC Science and Innovations.
Licensing of operations in the nuclear power industry, as well as supervision of day-to-day operations of
design, construction and operating organisations is the responsibility of an independent government body,
namely the Federal Environmental, Industrial and Nuclear Supervision Service of Russia (Rostekhnadzor).
Nuclear and radiation safety management functions in the nuclear industry are performed by the following
divisions of ROSATOM:
-
The General Inspectorate participates in the preparation of proposals for shaping the government
policy on nuclear and radiation safety, implements measures to ensure the safety of nuclear facilities
and monitors safety in the Company's organisations;
The Nuclear and Radiation Safety, Licensing and Permitting Department ensures that personnel and
equipment are ready to respond to emergencies at nuclear facilities and monitors the implementation
of emergency prevention measures;
The Directorate for Public Policy on Radioactive Waste (RAW), Spent Nuclear Fuel (SNF) and Nuclear
Decommissioning plays a leading role in the management of government programmes aimed at
addressing 'nuclear legacy' issues;
The Technical Regulation Department updates the system of technical specifications for the safe use
of nuclear energy.
Nuclear and radiation safety at nuclear facilities
In 2022, JSC Atomenergoprom ensured safe and
reliable operation of nuclear organisations. There
were no incidents involving radiation leaks. Limits on
employee radiation exposure were not exceeded. No
licences were revoked in the nuclear industry.
Although there was no significant deterioration in
the epidemiological situation or the risk of spread of
COVID-19 in 2022, some of the targeted inspections
organised by the General Inspectorate and other
divisions of the Corporation in early 2022 were carried
out remotely.
Nuclear power plants
The safety status of nuclear facilities is assessed based
on the number and scale of recorded deviations in their
operation, which are benchmarked against the IAEA
International Nuclear and Radiological Event Scale (INES).
Events on the scale are rated at seven levels: the upper
levels (4-7) are termed 'accidents', while the lower levels
are 'incidents' (2-3) and 'anomalies' (1). Events that have
no safety significance are classified as below scale, at
level 0. Events that have no safety relevance are classified
as 'out of scale'.
No events rated at level 1 or higher on the international INES scale have been detected at Russian nuclear
power plants since 201864
In 2022, there were 37 deviations rated at level 0 and out of scale. JSC Rosenergoatom investigated all
deviations in accordance with the prescribed procedure. Their causes were identified: most of the deviations
were caused by failures of thermal and electrical equipment due to manufacturing defects which had not
been detected during the installation and adjustment of the equipment. Some of the deviations were caused
by errors made by the personnel. The Company rated each event that had occurred in accordance with the
INES Scale User's Manual and developed corrective measures to prevent similar failures in the future.
