ABSTRACT:
A heat exchanger for transferring heat from primary fluid to secondary fluid and particularly one which is especially suitable for cooling a fast breeder nuclear reactor is disclosed herein. The heat exchanger includes a plurality of thermally conductive, concentric shells spaced apart from one another so as to define a number of primary annular spaces and physically isolated secondary annular spaces therebetween. The primary fluid is directed in a continuous flow through the primary annuli, while at the same time the secondary fluid is directed in a continuous flow through the secondary annular spaces.
