Russian power companies and those partnering with the power industry generate a strategic objective to optimize production and management costs while maintaining high quality of the products and services conforming to the international and domestic standards. This inevitably requires reorganization of business processes at all management levels.Sustainable development and energy efficiency of the Russian economy depends on a number of factors; one of the essential factors is effective management of production enterprises.The key method for improving the management efficiency is an array of instruments applied in leading industrialized countries worldwide and known as the “lean” production ("lean manufacturing") concept.In the last 20 years, Russian production enterprises have tried to introduce both lean production methods, and separate tools in practical management. Large power corporations, such as Gazpromenergoholding, Rosatom arrived at meaningful positive results. Lean production practices in Russia are topical for research into methods and primary ways of adopting the lean production (LP) instruments by the domestic industry.The objective of the research is to classify and provide quantitative assessments of expected positive economic effect through adoption of the lean production instruments at nuclear industry enterprises.The methodological framework for the research included lean production state standards (GOST) and research reports by foreign and domestic authors doing research into the LP concept, models and instruments.The information base of the research consists of data from foreign and domestic scientific publications, Rosatom State Corporation’s official data and open data from professional communities’ websites.
