NPP construction projects are distinguished by long construction periods (5-7 years), huge investments (up to 30 billion US dollars), and exposure to negative factors affecting the entire commissioning period and project cost. The complexity of the project management of such mega-project requires a set of special techniques and strong analytical and methodological support of decision-makers. The article discusses the practical aspects of identifying a reasonable degree of specialization of participating contractors. For an assessment of the contractor’s specialization level, the process specialization degree (DS p ) indicator used. It describes the share of key types of works in their total volume, performed on their own. Construction company’s specialization considered as a vehicle ensuring the fullest application of state-of-the-art achievements of the construction science and technology in order to achieve the best technical and economic performance indicators of specialized entities, including improved labor productivity, reduced cost of works, maximized profit. The optimum specialization level and a degree in case of construction of major power complexes were assessed using the example of Belarus NPP chosen as a representative facility. The proposed approach to the determination of a reasonable degree of specialization allows construction entities to plan this parameter for short-term or long-term periods, to assess the economic efficiency of the specialization, subject to its increasing degree. As the achieving of the specialization degree is conditioned, the reasonable DS p delimitation is essential not only in economic but also in social terms. This article will be useful for the management of engineering, design, and contracting companies planning their participation (or already involved) in the investment and construction project in foreign countries.

This article considers the problem of ensuring the growth of export capacities of the industrial construction of nuclear power facilities in the global markets through the simulation and management of the organizational reliability during the pre-investment stage. This research is made relevant by a high level of uncertainty in the implementation of international investment projects for nuclear power when over 60% of the world’s nuclear reactors are constructed with delays and at increasing costs. The purpose of this research is to develop methodological approaches and practical recommendations on the modeling and complex management of organizational reliability indicators for the industrial construction of nuclear power facilities in the global markets during the pre-investment stages. This article presents the following results: the simulation procedure for the organizational reliability and life cycles of the industrial construction of nuclear power facilities developed by the authors, development specifics and trends for this type of industrial construction, recommendations concerning the organization of industrial construction to improve the reliability of nuclear power facility construction based on a managed factor space and multi-criterion optimization of calendar schedules. The conceptual approach to modeling and management of the organizational reliability of nuclear power industrial construction and operation life cycles in question can be determined as a promising market tool that can be used to regulate the increase of the competitive abilities of the Russian branches of Rosatom State Corporation. This stipulates facilitating the growth of the industrial construction of nuclear power facilities in the global market from the current share of Rosatom State Corporation of 26% (120 billion USD) to 40-50% before 2035 through the improvement of the organizational reliability of the implementation of this type of investment projects.

Involvement in the construction of nuclear power plants worldwide is a promising direction for developing the re-search and technological potential of engineering and general contracting companies in Russia. Nevertheless, Russian companies, involved in the construction of nuclear power plants (NPPs) abroad, need to adapt to foreign jurisdictions, their requirements and rules applied to the construction of hazardous industrial facilities, as well as unique social, economic and physical environments. In this regard, international activities, performed by Russian companies, are associated with uncertainty and risks that require the study and systematization of risk factors and development of risk management models. The statistical data, covering the recent ten-year period, illustrates the level of uncertainty and problems arising in this area. Over 60 % of nuclear reactors worldwide are built with a delay in construction. The consequences of such delays boost project costs. Major international corporations, implementing nuclear power plant construction projects abroad, consider the insufficient pre-project study of project organization and management issues at the stage of entering into an EPC (M) contract to be the risk factors arising in the pre-investment phase. Risk management modeling is considered as the main element of the system designated for managing the organizational and economic reliability of the pre-investment phase of NPP construction in the international market. It includes: (a) structuring a multiparametric risk factor space based on four sources, including, on the part of the customer, the EPC (M) contractor, the contract and the external environment; (b) a pre-investment risk management model, applicable to NPP construction abroad, to be based on the overall project risk P(rt1); (c) a mathematical model for selecting a project implementation option based on the multicriterial optimization of the future-oriented project plan-schedule.

Research encompasses up to date references and expertise on the world market of new NPP construction. An insufficient level of comprehensive scientific analysis of organizational aspects was noted considering the project life cycle of nuclear power plants (NPP) as economic systems and customer needs at the micro, meso and macro levels. It makes the analysis relevant for the nuclear industry and the development of sales methodology for high-tech infrastructure projects, as well as implementation of the pre-investment stage of such a project. The theoretical basis of the study provides a definition of sustainable development, which is the key to the analysis. The main part of the research contains a description of the methodology and research procedure: a systematic approach and a marketing analysis algorithm with elements of M. Porter's "competitive diamond" methodology are used. In the description of the study based on the forecast of development up to 2040, the capacity of the target market for Russia is estimated. The market segmentation has been carried out. Most of the NPP projects are implemented in developing countries and "newcomers," which seek to gain several benefits from the launch of the nuclear program. An analysis of competition led to the conclusion that there is a formed "buyer's market," competition has increased due to the new exporting countries of nuclear power plants. It is revealed that competitiveness is estimated at three levels: micro (NPP project), meso (financial and organizational model of the project) and macro (project effects on the economy, ecology, society). Local "optima" are not achievable; the success of the transaction on nuclear power plants (as an economic system) is determined by the integral assessment. The evolution of Russia's positioning in the world market is analyzed, elements of Russian strategy and tactics are systematized: the strategy of integrated sales and phased penetration, which is designed to ensure the competitiveness of micro, meso and macro levels. Integrated sales, including the supply of nuclear power plants, fuel, service, training, etc., are a "derivative" of the needs of the recipient country of the nuclear power plant. The central place in developing a strategy is to define goals and values for stakeholders of a nuclear power plant project at the micro, meso and macro levels, which constitutes a multi-focus sales strategy. The requirements of the electricity sales market, financial and technological partners, determine the specific transaction features. The combination of a competitive strategy and a strategy for long-term cooperation makes up the hybrid nature of the sales strategy. Existing and prospective tactics include account management, customer analysis using the method of strategic networks, modeling of electricity sales markets, and a requirements management system. The presented business model of the sales strategy allows us to form a list of factors, methods, mechanisms, resources and corporate

The problems of managing the organizational reliability of the pre-investment phase of the industrial construction of nuclear power plants in global markets have been investigated. The relevance of the topic is determined by the great uncertainty in the implementation of international investment projects of nuclear power plants. This is confirmed by the facts of construction delays and an increase in costs by more than 60% of nuclear reactors under construction in the world.Purpose of research: development of methodological approaches and practical recommendations for modeling and integrated management of organizational reliability indicators of industrial construction of nuclear power plants in the global market at pre-investment stages.Methods: a set of systematic methodological approaches based on methods of comparison, analysis, synthesis, modeling, forecasting, expert assessments, mathematical statistics, economic and mathematical modeling, factorial, situational and retrospective analysis, scenario method, morphological and logical analysis.Results: the author's methodology for modeling organizational reliability and the structure of the life cycle of industrial construction of nuclear power plants; features and development trends of this type of industrial construction; recommendations in the field of industrial construction organization to increase the reliability of NPP construction based on a controlled factor space and multi-criteria optimization of calendar schedules.Conclusion. The studies performed have confirmed the relevance of studying the subject of research associated with solving the problem of increasing the organizational reliability of industrial construction of nuclear power plants in global markets, formed and managed at the pre-investment stages of planning these types of investment projects. At the same time, the main result of these studies can be considered as an increase in the competitiveness of the Russian divisions of Rosatom State Corporation in the international market with an increase in its current share of 26% (130 billion US dollars) to 40-50% for the period up to 2035.
