The EDS battery can provide four hours of power to the hydrogen igniter in the event of a plant loss of power. The empirical feedback of the fukushima event is considered, and the hydrogen igniter is used as a main hydrogen elimination means and measure under the condition of serious accident. Therefore, the power supply capacity of the hydrogen igniter under the serious accident condition is guaranteed to be one of indispensable requirements, and in order to further eliminate risks, a 1E-level direct current and UPS system (IDS) standby sequence storage battery and a low-voltage mobile power supply are connected to serve as redundant power supply means, so that the continuous power supply capacity of the hydrogen igniter under the serious accident condition is guaranteed.
