The oil production in Ukraine is constantly decreasing. In these conditions it is appropriate to use tertiary methods of intensifying in oil production which increase the mobility of oil. These include a method based on injection into the layer a hot water to raise the temperature of oil that lead to a decrease its viscosity and increase mobility. Aim: The aim of this research is a technical economic feasibility study of constructing and using the nuclear power complex for oil production in order to increase the oil extraction from oilfields in their late stages of production by the example of Okhtyrka oilfield (Ukraine). Materials and Methods: Okhtyrka oilfield is considered the most promising in Ukraine. The explored raw material potential can provide the stable oil production about 2 millions tonnes annually during 50...60 years. On the basis of aerospace photos the oilfield can be divided into three areas which are called North, Central and South. The possible nuclear power plant location selected on the basis of wind rose relative Okhtyrka city and heating networks scheme from NPP to the injection wells. Results: It was developed and designed the key diagram of turbine plant K-1000-5,8/50 with a cogeneration plant which provide the technological coolant for injection into the wells. In rated mode the turbine with cogeneration plant provides 675 t/h of technological coolant at temperature of 250 °C and has electrical power 935.6 MW. As a result of calculating the profit from the sale of electricity and additional oil per year with account of annual operating costs, we determine that the profit equal to 1063.37 millions USD.
