Section: claims

1. An autonomous, decentralized fast breeder reactor system comprising: a single main vessel of a nuclear reactor;  a plurality of unit-type nuclear reactor subsystems disposed in said main vessel and each having a small-scale faster breeder reactor core;  a plurality of steam generator subsystems disposed in said main vessel;  a first coolant circulating naturally through the interior of said main vessel;  a second coolant circulating naturally through the interior of each unit-type nuclear reactor subsystem; and  means for causing a heat transfer to take place between each unit-type nuclear reactor subsystem and each steam generator subsystem by said first coolant circulating naturally through the interior of said main vessel and undergoing a heat exchange with said second coolant circulating naturally through the interior of each unit-type nuclear reactor subsystem.  a turbine system for introducing generated steam from a steam generator subsystem, and  a heat accumulating pool for cooling condensate of a turbine. 2. The system according to claim 1, wherein said unit-type nuclear reactor subsystems are arranged on an inner peripheral portion of said main vessel, and said steam generator subsystems are arranged at a central portion of said main vessel. 3. An autonomous, decentralized fast breeder reactor system comprising: 4. The system according to claim 3, further comprising emergency cooling means in which piping from said heat accumulating pool is connected to a central portion of a fast breeder reactor. 5. An autonomous, decentralized fast breeder reactor system, comprising an autonomous, decentralized fast breeder reactor, a turbine system for introducing generated steam from said fast breeder reactor, a heat accumulating pool for cooling condensate of a turbine, and an industrial robot for controlling said fast breeder reactor, wherein said autonomous fast breeder reactor system is located underground.
