В данной магистерской диссертации проведен комплексный сравнительный анализ нормативных документов в области устройства и эксплуатации локализующих систем безопасности атомных электростанций (АЭС). Локализующая система безопасности является важнейшим компонентом общей системы безопасности АЭС, и ее правильное устройство и эксплуатация необходимы для предотвращения радиоактивных выбросов в случае аварии. В данной магистерской диссертации проводится сравнительный анализ нормативных документов в области устройства и эксплуатации локализующих систем безопасности для атомных электростанций США, Российской Федерации и Южной Кореи. Цель - выявить сходства и различия в подходах к регулированию в этих странах и дать рекомендации по повышению безопасности локализующих систем безопасности на АЭС. Нормативные документы были собраны, рассмотрены и проанализированы для выявления различий, сходств и областей, которые могут нуждаться в улучшении. Данная магистерская диссертация вносит вклад в понимание нормативных подходов в области устройства и эксплуатации локализующих систем безопасности для атомных электростанций в США, Российской Федерации и Южной Корее. Результаты данного исследования могут быть использованы в процессе принятия решений, разработки политики и международного сотрудничества в целях повышения безопасности атомных электростанций во всем мире.

This master thesis undertakes a comprehensive comparative analysis of regulation documents in the field of arrangement and operation of localizing safety systems for Nuclear Power Plants (NPPs). The localizing safety system is a critical component of the overall safety system in NPPs, and its proper arrangement and operation are essential for preventing radioactive releases in the event of an accident. This master thesis conducts a comparative analysis of regulation documents in the field of arrangement and operation of localizing safety systems for nuclear power plants in the United States, Russian Federation, and South Korea. The objective is to identify similarities and differences in regulatory approaches among these countries and provide recommendations for enhancing the safety of localizing safety systems in NPPs. Regulatory documents were collected, reviewed, and analyzed to identify differences, similarities, and areas that may need improvement. This master thesis contributes to the understanding of regulatory approaches in the field of arrangement and operation of localizing safety systems for nuclear power plants in the United States, Russian Federation, and South Korea. The findings of this research can inform decision-making processes, policy development, and international cooperation efforts to improve the safety of nuclear power plants worldwide.
