Fast breeder reactor.

摘要

A fast breeder reactor having an intermediate heat exchanger (21) into which a liquid metal in one of both cooling systems of a primary cooling system and a secondary cooling system of the fat breeder reactor is introduced as a primary fluid and a liquid metal in the other cooling system as a secondary fluid, the secondary cooling system being furnished with a pump which causes the liquid metal in this secondary cooling system to flow; characterized in that the intermediate heat exchanger (21) is constructed of a magnetic field generator (23, 24), and a channel which is so formed that its flow direction is set to a direction traversing a magnetic flux produced by the magnetic field generator, the channel being partitioned by an electrically-conductive heat transfer plate (30) to define a primary cooling system channel (31) through which the primary fluid is passed and a secondary cooling system channel (32) through which the secondary fluid is passed. When one of the primary and secondary fluids is caused to flow by the pump (6) within a magnetic flux established by the magnetic field generator (23, 24) and while defining an angle to the magnetic flux, current is induced, and the other fluid flows subject to the current and the magnetic flux of the magnetic field generator, whereby heat is exchanged between both the fluids through the heat transfer plate (30) during the flow of both the fluids. The common structure achieves a heat exchange function and a pumping function which can contribute to the miniaturization of the fast breeder reactor.
