Abstract: 

An effective application of hydrogen technologies at nuclear power plants is
proposed; it improves the plant maneuverability at normal operation, and secures
own electricity needs in case of station blackout. Probabilistic assessment of the
NPP’s emergency power supply reliability is conducted, under the station blackout
condition and simultaneous use of the additional, permanently operating steam
turbine and emergency power supply system with diesel generators.
The proposed system with additional steam turbine can use the core residual
heating for shutdown cooling for the period of 72 hours. In case of blackout at a
plant with several units, the additional steam turbine’s power is supported by
additional steam, generated by hydrogenoxygen combustion. It is found that the
proposed scheme with a permanentlyoperating smallpower additional steam
turbine installed at NPP, in combination with the hydrogen facility, increases the
emergency electric power supply reliability at station blackout accidents
