Embodiment Construction

[0021] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0022] Such as figure 1 As shown, the present invention provides a novel fast reactor fuel plant layout structure, which divides the fuel plant into a spent fuel plant 5 and a new fuel plant 7 according to the plant functions; the spent fuel plant 5 is arranged on the base plate where the reactor plant 1 is located ; The new fuel building 7 is set separately and connected with the reactor building 1 through a transport passage. The new fuel building 7 is located on the side of the spent fuel building 5, independent from the main building of the nuclear island, and arranged separately. The new fuel assembly is directly transported to the reactor building 1 through the transportation channel.

[0023] In this embodiment, steam generator building 2, electrical building (including No. 1 electrical building 3 and No. 2 electrical building 4), personnel pa...

Abstract

The invention relates to a novel fast reactor fuel plant arrangement structure. A fuel plant is divided into a spent fuel plant and a new fuel plant according to a function of the plant; the spent fuel plant is arranged on a base plate where a reactor building is disposed, and the new fuel plant is separately arranged and is connected with the reactor building through a transport corridor. The novel fast reactor fuel plant arrangement structure has the advantages that new fuels and spent fuels are separately stored under the premise of meeting the functional requirements of a fast reactor forthe fuel plant, the relatively safe new fuels are separately arranged, so that the area of a nuclear island main plant is reduced, and the safety is higher.

Description

technical field [0001] The invention relates to a nuclear island powerhouse structure, in particular to a novel fast reactor fuel powerhouse layout structure. Background technique [0002] Fast reactor is the abbreviation of fast breeder reactor, which belongs to the fourth generation technology in the current development of nuclear power. Its important feature is that while consuming nuclear fuel, it produces more nuclear fuel than it consumes. The fuel utilization rate of fast reactors is as high as 60% to 70%, which is of great significance to make full use of my country's uranium resources, promote the sustainable development of nuclear power, and solve my country's follow-up energy supply problems. [0003] The plant layout of fast reactors has both similarities and differences with those of common pressurized water reactors. The common thing is that the functions and types of the factory buildings are roughly the same, but the difference is that the layout and structu...
