Abstract

The method of using the start-up reserve steamshops installed at the NPP to improve the safety and economic efficiency of the plant was proposed in the article. Earlier, the author of the article proved on the basis of experimental data from the Balakovo NPP that a lowpower steam turbine can provide power supply for the NPP's own needs through the use of the core residual heat release. Such steam turbine can effectively work in conjunction with a startup reserve steamshops in the normal mode to generate additional electricity to the power system and to provide a reliable reserve for NPP own needs in case of the station blackout. In the article, the characteristics of the known units corresponding to the developed system are presented, and the cooldown process based on the developed method is described.
