Abstract
Nuclear reactor exchanger which assures the transfer of heat between two streams of coolant sodium. It includes an outlet connector which channels coolant sodium leaving a bundle of exchanger tubes traversed on the inside by the sodium and immersed externally in coolant sodium, and an inner tubular jacket forming a surface of revolution about a vertical axis and an outer tubular jacket. The wall of the inner jacket has a folded portion distinguished by at least one flank in the form of a crown.
Claims5
A heat exchanger for a fast neutron reactor, comprising
- (a) a bundle of tubes fixed at their ends to upper and lower tube plates each having the form of crown, said tubes being located between outer and inner sleeves for channeling a stream of primary sodium circulating around said tubes;
- (b) an inlet tube passing inside said inner sleeve for leading a stream of secondary sodium to the inlets of said tubes, so that said secondary sodium circulates within said tubes;
- (c) an inner tubular jacket surrounding the said inlet tube and an outer tubular jacket connected together at the top so as to form an annular chamber which channels said secondary sodium at the outlets from said tubes, said inner tubular jacket having a folded portion comprising at least one flank and forming at least one annular throat.
