Analysis of the Opportunity for an Increase in the Thermal Power of Power Generating Units of Nuclear Power Plants (Part 1)

Abstract

For Ukraine the realization of available reserves to increase the power of operating power units of nuclear plants is a vital problem the solution of which would allow us to increase electric power output. A special role is also played by economic priorities; in particular an increase in power by 1 kW is ten times cheaper in comparison with the construction of 1 kW of new power facilities. One more factor is the world experience in the field of an increase in the thermal power of operating power units of nuclear power plants. Based on the specified urgency this scientific paper analyzes the international experience gained in the field of an increase in the thermal power of the power units for nuclear power plants and describes the main mechanisms and instrumentation required for the realization of the given modification of nuclear power units in Ukraine. The reserves embedded into the project to enable an increase in the thermal power of power units were represented graphically. Recommendations on the scope of appropriate measures to be taken and substantiations required for the implementation of the appropriate level of an increase in the thermal power of Ukrainian power units with water-moderated water-cooled power reactors VVER-1000 and VVER-440 have been given.
