Abstract

The invention relates to the technical field of nuclear power equipment and particularly relates to a middle shell and a safety injection tank. The middle shell comprises a body, wherein a cavity is formed in the body and penetrates through the body along the extension direction of the cavity so as to form a first opening and a second opening; a first reinforcing part and a second reinforcing part are arranged in the cavity of the body; the first reinforcing part is arranged at the first opening, two ends of the first reinforcing part along the length direction are connected with the body, and the length direction of the first reinforcing part is vertical to the extension direction of the cavity; and the second reinforcing part is arranged at the second opening, two ends of the second reinforcing part along the length direction are connected with the body, and the length direction of the second reinforcing part is vertical to the extension direction of the cavity. The safety injection tank comprises the middle shell. According to the middle shell and the safety injection tank, the technical problems that an existing safety injection tank is easy to be structurally changed and difficult to correct are solved.

Description

technical field [0001] The invention relates to the technical field of nuclear power equipment, in particular to a middle casing and a safety injection box. Background technique [0002] The components of a nuclear power plant are usually referred to as nuclear power equipment. Nuclear power equipment is mainly divided into three categories: nuclear island equipment, conventional island equipment, and auxiliary systems (BOP). Among them, nuclear island equipment includes reactor core, reactor pressure vessel, reactor internals, control rod drive mechanism, steam generator, main pump, main pipeline, safety injection tank, boron injection tank and pressurizer, etc.; conventional island equipment includes Steam turbines, generators, deaerators, condensers, steam-water separation reheat gas, high and low pressure heaters, main feed water pumps, fuel transfer devices, condensate pumps, main transformers and circulating water pumps, etc.; auxiliary systems other than the nuclear ...
