In 2022, as part of efforts to ensure compliance of the industrial safety management system with new mandatory requirements, JSC Atomenergoprom continued to manage the risk of accidents at hazardous industrial facilities in accordance with the Uniform Industry-Wide Guidelines on the Establishment of an Industrial Safety Management System in ROSATOM's Organisations. All equipment used at hazardous industrial facilities undergoes timely technical inspection and indus- trial safety assessment. Compulsory insurance is arranged in accordance with the law on compulsory third-party liability insurance for the owner of a hazardous facility for potential damage from an accident at the hazardous facility. There were no events classified as accidents at hazardous industrial facilities of JSC Atomenergoprom. Calculations of metrics used to assess the probability of potential negative consequences of non-com- pliance with industrial safety requirements at hazardous industrial facilities show that the level of risk of accidents is acceptable. In 2023, the Company plans to continue improving the industrial safety management system, to organise a meeting on industrial safety matters with representatives of JSC Atomenergoprom's organisations (to discuss current matters related to industrial safety), and to hold an annual R&D workshop on industrial safety (to provide training and inform about the latest developments in the sphere of legal regulation).
