摘要： A heat exchanger having an intermediate heating medium is provided. A multiplicity of inner tubes 2 are disposed in a shell 1 of a heat exchanger 10. A low-temperature heating medium Y (water) flows in these inner tubes and a high-temperature heating medium X (liquid sodium) flows in the shell. These inner tubes are divided into a plurality of groups so that each group has a plurality of said inner tubes. The plural inner tubes constituting one group are disposed in one outer tube 3, and an intermediate heating medium Z chemically inactive with respect to both the high-temperature heating medium and the low-temperature heating medium and excellent in heat transferring performance is passed through each outer tube. The possibility that the high-temperature heating medium and the low-temperature heating medium contact each other can be reduced to an extremely low level. By providing leakage detectors capable of detecting with respect to each of the outer tubes the high-temperature heating medium or the low-temperature heating medium leaking out into the intermediate heating medium flowing out of the outer tubes, the damage to the inner tubes of each group can be detected and identified speedily.

摘要： An autonomous, decentralized fast breeder reactor includes a single reactor main vessel which houses a plurality of small-size reactor subsystems each having a small-scale fast breeder reactor core, and a plurality steam generator subsystems. These subsystems function in an autonomous manner and are caused to undergo a heat transfer with one another by a coolant circulating naturally through the interior of the main vessel, thereby constructing a cooperatively operating system. Steam generated by the steam generators is introduced to a turbine system and utilized in generating electricity. The condensate from the turbines is cooled by a heat accumulating pool, and the heat is utilized in a separate system. The entire system is installed underground and use is made of the difference in elevation. Use also is made of solid bedrock to construct a housing facility for the reactor.
