Abstract: A powered door for nuclear power plant consists of an embedded steel plate, a door frame welded on the embedded steel plate, a pair of hinge devices, a group of door panels, a group of opening and closing devices and a group of bolt devices; the door panels are fixedly arranged within the door frame through the hinge devices; the opening and closing devices are arranged at the upper ends of the door panels, and the bolt devices are arranged in the internal sides of the door panels. The powered door is fire-proof, explosion-proof and bulletproof, and is safe and long in service life, thus, the powered door can be used for nuclear power engineering which is constructed based on new standards.
