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...
