Liquid metal cooled, loop-type fast neutron nuclear reactor, compact.

Abstract

A compact, liquid-metal cooled, loop-type, fast neutron reactor. The invention relates to a primary / secondary heat exchanger with identical loops, each consisting of a heat transfer module arranged axisymmetrically around the reactor block. Each module comprises an expansion tank (20), a heat exchanger (21), and an electromagnetic pump (22), which alone forms a heat exchange loop between the liquid sodium primary circuit and the gaseous secondary circuit, such as nitrogen, which is a closed Brayton cycle.
