The present invention provides a device gate for nuclear power plant including a shell ring fixedly connected to a penetrating piece of containment. The device gate for nuclear power plant further includes: a gate seal head corresponding to an end surface of the shell ring and configured for being sealedly connected to the shell ring; a hoisting lifting assembly positioned above the gate seal head and movably connected to the gate seal head, and configured for performing hoisting and resetting on the gate seal head; a high-position suspending assembly positioned above the gate seal head and configured for being detachably connected to the gate seal head when the gate seal head is hoisted to a specified position; and an anti-seismic limiting assembly, partially provided on the containment and movably connected to the gate seal head, and configured for performing limiting and anti-seismic processing on the gate seal head when the gate seal head is suspended on the high-position suspending assembly. The present invention ensures reliability and anti-seismic requirements of the device gate for nuclear power plant.
