Abstract
Today, an important task for the economy is to increase the efficiency of using primary fuel. At present, for nuclear power plants with VVER reactors, thermal efficiency is about 33%, with fast neutron reactors - more than 40%. This means that most of the heat produced is released into the atmosphere. In this paper, we consider methods to solve the problem of increasing energy efficiency by the example of NPPs with fast neutron reactors due to the utilization of low-grade waste heat. The results of practical implementation of utilization of low-potential thermal energy of thermal and nuclear power plants using heat pumps were generalized. The analysis of the utilization efficiency of waste heat from various NPP systems was performed.
Highlights
The creation of a competitive electric power market in Russia inevitably leads to the fact that energy companies are forced to look for new ways to improve the efficiency and cost-effectiveness of their activities
One of the possible ways to reduce thermal discharges from nuclear power plants is the use of heat pumps in the design of a steam turbine plant, which helps reduce environmental burden by cutting down thermal emissions from disposing of waste heat
The purpose of this work is to investigate the possibility of energy efficiency increasing of NPPs with fast neutron reactors due to the utilization of low-grade heat discharged from auxiliary systems
Summary
The creation of a competitive electric power market in Russia inevitably leads to the fact that energy companies are forced to look for new ways to improve the efficiency and cost-effectiveness of their activities. Today, the issue of developing new energy-saving technologies for the purpose of more efficient use of energy resources remains a pressing problem in the power industry of Russia. In the operation of thermal power plants and nuclear power plants, it is necessary to take into account the factor of thermal pollution of the environment, which leads to significant environmental consequences, both on a local and a global scale. One of the possible ways to reduce thermal discharges from nuclear power plants is the use of heat pumps in the design of a steam turbine plant, which helps reduce environmental burden by cutting down thermal emissions from disposing of waste heat
