The present invention relates to the technical field of automatic depressurizing systems for steam in nuclear power plants, and in particular, to a novel automatic depressurizing system and method for a nuclear power plant, which is a passive design. The novel automatic depressurizing system comprises a voltage stabilizer, an ADS isolation valve, an ejector, an upper water tank located in a containment, a bubbler, a lower water tank, an ADS discharge pipeline, and a water suction pipeline. An outlet end of the voltage stabilizer is sequentially connected to the ADS isolation valve, one water inlet of the ejector, and the bubbler by using the ADS discharge pipeline. The bubbler is located in the upper water tank, and the lower water tank is connected to the other water inlet of the ejector by using the water suction pipeline. Compared with the prior art, in the present invention, energy released during steam ejection can be effectively utilized, such that the energy originally discharged directly into the upper water tank is effectively utilized, and meanwhile, a water source which is not used in the lower water tank originally is pumped into the upper water tank, and the size of the upper water tank can also be reduced, such that the arrangement space inside the containment is utilized to the maximum extent, and the safety and economy of the nuclear power plant are finally improved.
