Fast reactor nuclear island main plant group arrangement structure

Abstract

The invention belongs to the technical field of nuclear power plant design, and relates to a fast reactor nuclear island main plant group arrangement structure. The fast reactor nuclear island main plant group arrangement structure comprises a reactor plant located in the center and further comprises a steam generator plant, a first electric plant, a second electric plant, a spent fuel plant, an operation service plant, a corridor and a steam turbine plant which are located on the periphery; the steam generator plant and the spent fuel plant are arranged in the mutually symmetrical direction;the first electrical plant and the second electrical plant are arranged in the mutually symmetrical direction; the operation service plant and the steam generator plant are connected with the first electric plant or the second electric plant; and the corridor is located on the periphery of the steam generator plant and connected with the steam generator plant, and the other end of the corridor isconnected with the steam turbine plant. By utilizing the fast reactor nuclear island main plant group arrangement structure, the requirements of design and operation modes of a fast reactor system canbe efficiently and reasonably met, and safety and economical efficiency of a nuclear island main plant group are guaranteed from the angle of arrangement design, so that the technical and safety requirements of the four-generation nuclear energy system are met.

Description

technical field [0001] The invention belongs to the technical field of nuclear power plant design, and relates to an arrangement structure of a fast reactor nuclear island main building group. Background technique [0002] Fast reactors are reactors with fast neutron-sustained fission chain reactions, and are one of the preferred reactor types for fourth-generation advanced nuclear energy systems in the world. The closed cycle of nuclear fuel formed by the fast reactor can improve the utilization rate of uranium resources and minimize the generation of nuclear waste. Fast reactors have been widely recognized domestically and internationally for their unique advantages in improving the utilization rate of uranium resources and facilitating the treatment of nuclear fuel waste. The development of fast reactors and closed fuel cycles can be matched with the rapid development of pressurized water reactors, which can realize the safe, economical, environmentally friendly and larg...

AI Technical Summary

Problems solved by technology

[0003] At present, most of the nuclear power plants that have been built or are under construction are pressurized water reactor nuclear power plants. Since the system configuration and operation mode of the fast reactor nuclear power plant are completely different from those of the pressurized water reactor nuclear power plant, the layout of the nuclear island main building group of the pressurized water reactor nuclear power plant Structs are not suitable for fast heaps
