Abstract

The invention provides a compactly arranged small-sized reactor primary loop overall structure. The structure is suitable for a marine operation environment, and comprises a pressure container, double-layer sleeve structures, inner-pile components, a control rod driving mechanism, a main pump, a steam generator, a pressure stabilizer, a main equipment integral support, a suppression pool, a primary shielding structure and the like. The steam generator is connected with the pressure container through one double-layer sleeve structure; the main pump is connected with the pressure container through one double-layer sleeve structure; the pressure stabilizer is connected with an evaporator through a surge pipeline; and the pressure container, the steam generator, the main pump and the pressurestabilizer are installed in the suppression pool through the integrated integral support. According to the system provided by the invention, the circulation of a nuclear reaction coolant in a reactorcoolant system can be ensured, realization of compact arrangement of a nuclear steam supply system is facilitated, and the heat exchange efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of nuclear power, in particular to an overall structure of a primary circuit of a compactly arranged small reactor. Background technique [0002] The main equipment of the primary circuit of the reactor coolant system mainly includes the reactor pressure vessel structure, the main pump, the steam generator, the pressurizer, etc. The main equipment of the existing nuclear steam supply system is connected by a long main pipe to form a closed loop. After being heated in the nuclear reactor, it is sent to the steam generator through the heat pipe connected to it, and the feed water on the other side of the steam generator is heated, and the heat-exchanged coolant enters the main pump through the transition pipe, and the main pump sends the coolant through the cold pipe to the main pump. was sent into a nuclear reactor, and so on. One of the heat pipe sections is connected with a voltage regulator, which is used...
