Abstract: The deluge valve assembly includes: a deluge valve, in which the deluge valve includes a water inlet cavity, a water outlet cavity, and a diaphragm cavity. The water inlet cavity is suitable for communication with the fire protection pipe network so as to make water from the fire protection pipe network flow into the water inlet cavity; a water inlet pipeline, in which an inlet of the water inlet pipeline is connected with the water inlet cavity, and an outlet of the water inlet pipeline is connected with the diaphragm cavity; a water outlet pipeline, in which an inlet of the water outlet pipeline is connected with the diaphragm cavity; reinforcement members, in which at least two of the deluge valve, the water inlet pipeline, and the water outlet pipeline are connected through the reinforcement members. The deluge valve assembly has advantages of good performance in anti-vibration and reliability.

Abstract: The invention discloses a serial high-temperature gas-cooled reactor nuclear energy system and an operating method thereof. The serial high-temperature gas-cooled reactor nuclear energy system includes a plurality of high-temperature gas-cooled reactors and a serial gas-cooled reactor. The high-temperature gas-cooled reactor includes a first reactor pressure vessel comprising a first reaction chamber for accommodating the first fuel element; a second reactor pressure vessel comprising a second reaction chamber interconnected with the first reaction chamber, allowing the first spent fuel in the first reaction chamber to enter the second reaction chamber.
