JSC Atomenergoprom Annual Report

JSC ATOMENERGOPROM / ANNUAL REPORT / 166 The risk of injuries remains high for employees who violate safety rules during the operation and maintenance of equipment, and for those employees who do not follow safety precautions when moving around the premises of an organisation. In addition to the injury frequency rate (FR), JSC Atomenergoprom also uses the lost time injury frequency rate (LTIFR), which enables it to benchmark the injury rate in the Company against that of other companies and countries. The LTIFR has been included in the KPI maps of all Division executives. The LTIFR reference value for the Divisions, units, holding companies and the Company as a whole has been set at 0.5, which is a good result for any company in any country in the world. Average LTIFR values achieved in Divisions, units and holding companies within the Company over the previous three years have been accepted as baseline (initial, to be improved) values for those Divisions, units and holding companies. The LTIFR targets are set individually for the Divisions, units and holding companies within the Corporation but do not exceed the baseline values. LTIFR in JSC Atomenergoprom's Divisions between 2020 and 2022 The statutory limit on radiation exposure of employees was not exceeded in 2022. There were no persons with a total effective dose of more than 100 mSv over five consecutive years (from 2017 through 2021). The annual dose limit of 50 mSv was not exceeded.

To reduce the injury rates in its organisations, the Company will implement measures focused on improving production processes, upgrading machine tools, developing a safety culture and enhancing controls. Radiation exposure of employees GRI 3-3 Ionising radiation is an occupational hazard specific to JSC Atomenergoprom's enterprises. Radiation safety criteria for personnel are laid down in the Radiation Safety Standards (NRB-99/2009), the Basic Sanitary Rules of Radiation Safety (OSPORB-99/2010) and other regulations. Most enterprises in the industry provide workplace conditions that fully meet the requirements set out in these documents. Average annual effective radiation dose for employees As at 31 December 2022, 42,385 people (group A personnel) in the organisations of JSC Atomenergoprom were under individual radiation exposure monitoring. Compared to 2021, the figure increased by 1.3%. In 2022, the average annual effective radiation dose for JSC Atomenergoprom's employees totalled 1.42 mSv. The average effective and collective radiation doses for personnel remain low and tend to decrease. In the structure of radiation exposure of employees, the share of employees with doses ranging between 2 mSv and 20 mSv tends to decrease (from -20% in 2020 to 18% in 2022).

Individual risk was calculated for 42,385 people. The vast majority of group A employees work in the conditions of acceptable occupational risk. For 596 people (1.4% of the total number of employees included in the IRAW system), individual risk exceeded the standard value of 10-3.
