Evaluation of Systemic Efficiency of NPP into Combiningwith Energy Complex Using Hydrogen Fuel
In the article was offered variants of the schemes combination NPP with energy complex u-sing hydrogen fuel. Goal is providing NPP by base electric load, increase of nominal power of unit NPP and generate of the peak electricity and also it possible to improve the reliability of the power supply to the needs of a nuclear power plant. In the one scheme hydrogen and oxygen produced in the night off-peak hours of electric load with consumption electricity from NPP and then fresh steam is overheating in front of the high-pressure cylinder using hydrogen and oxygen. In the second scheme considered use of additional steam turbine with the displaced heating steam for intermediate overheating with use hydrogen and oxygen burning. At this the displaced heating steam come and expansion in the additional steam turbine. Both variants of the schemes are comparing with gas turbine plant by criterion of the cost of peak electricity at prognosis costs on nuclear and gaseous fuel.
