The article presents the results of 25-old activity of the head agency of the Service for Disaster Medicine of the Ministry of Health of the Russian Federation – All Russian Centre for Disaster Medicine «Zaschita» (ARCDM «Zaschita») of the Ministry of Health of the Russian Federation in the sphere of medical support of population in case of radiation accidents. The Service is a functional subsystem of the Unified State system of prevention and liquidation of emergency situations, intended for elimination of medical and sanitary consequences of emergency situation. In Russia, it is legally established that in case of radiation accident the Federal Medical Biological Agency of Russia (the FMBA of Russia) is responsible for radiation safety of the population living in the NPP surveillance zone (approximately 25 km). Responsibility for the radiation safety of the rest of the population living outside the surveillance zone is assigned to the Service for disaster medicine. In accordance with the current document “Model content of the protection plan of the population in case of an accident at the radiation facility” developed by the Ministry of Emergency Situations, mandatory protective measures are provided in the territory that radius is 25 km around the radiation object (planning zones of preventive and emergency measures). Early planning in the restrictive planning zone is not envisaged, and protective measures outside the 100-kilometer zone are considered inappropriate. The article presents the concept developed by the specialists of ARCDM «Zaschita» for drafting protection of the subjects of the Russian Federation for the nuclear power plants operating on the territory of Russia. The concept is based on experience of consequences of the Chernobyl NPP accident. The concept argues that the outer boundary of the planning area for protective measures around nuclear power plants should have an outer radius of 1000 km. Radius of the emergency planning area is 100 km. The problems of preparedness for radiation safety of population support in case of radiation accidents are discussed. They are: the need for elaboration of regulatory and normative documents of the federal level on obligatory advance planning of protective measures against the possibility of radiation accidents on radiation-hazardous objects from the nuclear power plants on the territory of Russia for the population, not supervised by the FMBA of Russia (living both in the observation zone and abroad) and regulating the need and procedure of planning, organization and carrying out in case of necessity iodine prophylaxis for the population on territories up to 1000 km from operating NPPs of Russia. Same approaches to the solution of the considered problems are suggested.

The energy obtained at nuclear power plants is considered environmentally friendly, so an increase in the number of nuclear power plants is inevitable both in Russia and abroad. But the memory of accidents and incidents at nuclear power plants, their causes and destructive consequences should force all responsible participants in the process to follow the basic principles of defense in depth and safety culture. Analysis of the factors considered in the article indicates that the approach to the implementation of the principle of safety culture on the part of officials of the State Atomic Energy Corporation Rosatom and the world's second operating organization, Rosenergoatom Concern JSC, is subject to emasculation to the greatest extent. This indicates that the lessons of past accidents at nuclear power plants are not fully absorbed in the nuclear industry of the Russian Federation and the existing bureaucratic nihilism in relation to the fulfillment of the requirements of federal norms and rules requires urgent overcoming.

This article examines the current state of nuclear power in the Middle East. The construction of nuclear power plants is closely related to the issues of energy security in the region. The necessity and prerequisites for diversification of the energy balance in the countries of the region, as well as the need for a reliable source of electricity, which will completely solve the problem of growing demand, are analyzed. The authors analyze the role of the Russian Federation in the development of nuclear energy in the Middle East and assess the prospects in the market of services in this sector, consider cooperation in the nuclear sector with all states of the region, identify the advantages and prospects of Russia’s possible participation in the implementation of nuclear power plant construction projects in the Middle East. The most promising direction for the development of nuclear energy today is the use of fast neutron technology and a closed cycle that allows the processing of spent nuclear fuel. The possession of such technologies has a significant potential for export and international cooperation and is a significant technological advantage of Russia. Rosatom group has competitive advantages in the market of nuclear technologies, including in the Middle East, as it has competencies in all parts of the production and technological chain of nuclear energy. The Russian Federation participates in many projects related to the construction of nuclear power plants and related infrastructure and plays a significant role in the development of nuclear energy in the Middle East, cooperates with all countries in the region that are promising for cooperation in this direction, having intergovernmental agreements, which include the construction of nuclear power plants with such States as Egypt, Jordan, Iran, UAE, Turkey, Saudi Arabia, and memorandums of cooperation with Bahrain, Qatar, Kuwait, Oman.

Introduction. The article provides a system and statistical analysis of emergency situations associated with fires at nuclear power plants (NPPs) in various countries of the world for the period from 1955 to 2019. The countries, where fires occurred at nuclear power plants, were identified (the USA, Great Britain, Switzerland, the USSR, Germany, Spain, Japan, Russia, India and France). Facilities, exposed to fires, are identified; causes of fires are indicated. The types of reactors where accidents and incidents, accompanied by large fires, have been determined.The analysis of major emergency situations at nuclear power plants accompanied by large fires. During the period from 1955 to 2019, 27 large fires were registered at nuclear power plants in 10 countries. The largest number of major fires was registered in 1984 (three fires), all of them occurred in the USSR. Most frequently, emergency situations occurred at transformers and cable channels — 40 %, nuclear reactor core — 15 %, reactor turbine — 11 %, reactor vessel — 7 %, steam pipeline systems, cooling towers — 7 %. The main causes of fires were technical malfunctions — 33 %, fires caused by the personnel — 30 %, fires due to short circuits — 18 %, due to natural disasters (natural conditions) — 15 % and unknown reasons — 4 %. A greater number of fires were registered at RBMK — 6, VVER — 5, BWR — 3, and PWR — 3 reactors.Conclusions. Having analyzed accidents, involving large fires at nuclear power plants during the period from 1955 to 2019, we come to the conclusion that the largest number of large fires was registered in the USSR. Nonetheless, to ensure safety at all stages of the life cycle of a nuclear power plant, it is necessary to apply such measures that would prevent the occurrence of severe fires and ensure the protection of personnel and the general public from the effects of a radiation accident.

The paper presents review of the requirements from the new regulation NP 306.2.205-2016 “Requirements for Power Supply Systems Important to Safety of Nuclear Power Plants” and recommendations of IAEA and WENRA for the construction of electrical systems important to safety of nuclear power plants. The research is focused on main differences of NP 306.2.205-2016 from standards that applied to NPP emergency power supply systems (PNAE G-9-026-90, PNAE G-9-027- 91) and which were cancelled in 2016.
