Abstract

The invention provides an ADS containment system. A containment is an open container which s opened upward. An opened pressure vessel corresponding to the containment is arranged on the inner wall of the containment in an attaching manner, the containment is fixedly connected to the pressure vessel, a flow distributing ring plate is arranged in the middle of the bottom of the pressure vessel, a plurality of flow distributing holes are formed in the ring wall of the flow distributing ring plate, and an air cooling device is arranged out of the containment. The ADS containment system improves the reliability and safety of the containment, simplifies the structure and facilitates field mounting of equipment.

Description

technical field [0001] The invention belongs to the technical field of nuclear equipment, and in particular relates to an ADS (accelerator driven sub-critical system, accelerator driven sub-critical system) containment system. Background technique [0002] Generally speaking, a boiling water light water reactor (BWR) adopts a pressure-suppressed reactor containment vessel, which has the advantage of being able to reduce the volume of the primary containment vessel of the reactor. In the boiling water type light water reactor, the atmosphere in the primary containment vessel of the reactor is replaced with nitrogen, and the oxygen concentration is lowered than normal air to operate. Therefore, even if the core fuel becomes high temperature during an accident and reacts with the coolant to generate hydrogen, there is no need to worry about detonation or deflagration occurring in the primary containment vessel of the reactor. In addition, in the boiling water type light water ...
