Reactor pressure container and working method thereof

Abstract

The invention discloses a reactor pressure container and a working method thereof. The pressure container comprises a closed container main body, a flow guide ring cavity assembly and at least one inner connecting pipe; at least one filler neck is arranged on the side surface of the container main body; the flow guide ring cavity assembly is axially arranged in the container main body; the upper end of the flow guide ring cavity assembly is positioned above the filler neck and is connected with the inner wall of the container main body; the lower end of the flow guide ring cavity assembly is positioned below the filler neck and is connected with the inner wall of the container main body; the inner connecting pipe is arranged in the filler neck, one end of the inner connecting pipe is connected with the flow guide ring cavity assembly and the other end of the inner connecting pipe corresponds to the pipe orifice of the filler neck; the space among the periphery of the flow guide ring cavity assembly, the periphery of the inner connecting pipe and the inner wall of the corresponding container main body forms a flow guide ring cavity; an internal channel of the inner connecting pipe,an inner channel of the flow guide ring cavity assembly and the internal space of the container main body are communicated to form an internal flow channel; and the internal flow channel is isolated from the flow guide ring cavity. The reactor pressure container meets the compact type arrangement requirement and is suitable for the working condition of the sea.

Description

Technical field [0001] The invention relates to the technical field of nuclear power, in particular to a reactor pressure vessel and a working method thereof. Background technique [0002] Currently, energy supply is becoming increasingly tight. Small reactors are sought after by countries all over the world due to their wide applicability, shorter construction period and lower construction costs. They are vying to develop their own small reactors, especially offshore small reactors. [0003] Traditional land-based high-power reactors are not limited by space. In terms of reactor pressure vessels, the main pipeline structure that has a simple structure but takes up more space can be used to realize the circulation of the primary loop coolant. On the other hand, when small offshore stacks are installed in the cabin, space limitations must be considered, the height of the pressure vessel should be reduced as much as possible, and the compact arrangement with other main equipment; on ...

AI Technical Summary

Problems solved by technology

For small offshore stacks in the cabin, on the one hand, space limitations must be considered, the height of the pressure vessel should be reduced as much as possible, and it should be arranged compactly with other main equipment; on the other hand, small offshore stacks are affected by waves and may overturn Therefore, the wind load must be considered as a key design factor, while the traditional land-based stack does not have this consideration and is not suitable for marine conditions
