Abstract

The authors of the paper are grateful to A.I. Matunov, Deputy General Director for Geology and Subsoil Use of JV Budyonovskoye LLP, for rendering a valuable advice and assistance in collecting statistical data.

Highlights

  • World energy is one of the most important factors in the economic development of mankind

  • To increase the efficiency and reduce the expenditures for underground leaching of uranium in wells, taking into account the hydrogeological peculiarities of the deposit, the experimental works are recommended to conduct using the “pumping wells” technology

  • Constructed in the format of injection wells, namely, of the same diameter, without installing pumps. This reduces the expenditures for drilling operations, as well as for the extraction wells construction. The number of such pumping wells per technological unit is determined with account of the static groundwater level, which reduces the expenditures for the purchase and installation of submersible pumps

Summary

Introduction

World energy is one of the most important factors in the economic development of mankind. Nuclear power plays and will play an important role in energy production, both in the world as a whole (16% of the total annually generated electrical energy) and in economically developed countries, such as France (up to 75%), Sweden (38%), Finland (33%), the USA (19%), Great Britain (18%), Russia (17%), Canada (15%), etc [1]. At the end of 2017, there were 448 thermal reactors operating in the world, with a total power of 392 GW, consuming about 60 thousand tons of natural uranium per year, which is close to its annual production. It is noted by World Nuclear Association in Madrid, that world nuclear power growth is at a 25-year high. According to Ux Consulting prediction, by 2020, the number of reactors in the world will increase to 461 (power – 410 GW); prediction for 2030 – 533 reactors (power – 518 GW)[2]-[8]
