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 black-out. 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 hydrogen-oxygen combustion. It is found that the proposed scheme with a permanently-operating small-power additional steam turbine installed at NPP, in combination with the hydrogen facility, increases the emergency electric power supply reliability at station blackout accidents.
