  • Construction layout for underground caverns in nuclear island powerhouse of underground nuclear power plant
    Patent number: 10316662
    Abstract: A construction layout for underground caverns in a nuclear island powerhouse of an underground nuclear power plant, including: two primary caverns accomodating nuclear reactor powerhouses, combined caverns, electric powerhouse caverns, pressure relief caverns, a first primary traffic tunnel, a second primary traffic tunnel, a third primary traffic tunnel, a top adit system, a ground adit system, secondary traffic tunnels, and a side traffic tunnel. Each combined cavern and each electric powerhouse cavern are disposed at two sides of each primary cavern, respectively. Two combined caverns are in end-to-end connection and the arrangement direction of the two combined caverns are in parallel to the connecting line of the medial axes of the two primary caverns. Each pressure relief cavern is disposed between each combined cavern and a corresponding electric powerhouse cavern.
