Compact small reactor-loop main equipment structure connected by short pipes

Abstract

The invention provides a compact small reactor-loop main equipment structure connected by short pipes. The structure comprises a reactor body, a steam generator, a main pump and a pressure stabilizer,wherein the steam generator and the main pump form a loop and are connected to the reactor. The short pipes are connected between the reactor and the steam generator, between the steam generator andthe main pump and between the main pump and the reactor. The structure has the advantages of being compact in structure and high in pipeline safety, and occupies small space.

Description

technical field [0001] The invention relates to the technical field of nuclear power, in particular to a short-pipe-connected compact small reactor primary circuit main equipment structure. Background technique [0002] The main equipment of the primary circuit is the main equipment of the reactor coolant system. The main equipment structure of the existing primary circuit mainly includes reactors, steam generators, main pumps, voltage stabilizers and other equipment. These equipments are connected by long main pipes to form a loop structure. Among them, the reactor pressure vessel and the steam generator are connected by heat pipes. And one of the hot pipe sections is connected with a voltage stabilizer to adjust and maintain the pressure of the primary circuit; the water outlet of the main pump is connected to the pressure vessel through the cold pipe section, and the water inlet is connected to the steam generator through the transition section. In this way, along the lo...

Problems solved by technology

[0003] However, using the main pipeline to connect each device to form a loop structure makes the entire system occupy a large space, which cannot be applied to limited installation spaces such as cabins, and it is also difficult to meet the safety requirements of the pipeline in the marine environment.
