FAST NEUTRON REACTOR

摘要

The present invention relates to a fast neutron reactor comprising a main vessel (100) containing: - a core (4) made up of fuel assemblies (22) that can be cooled by a coolant (25), - means (6) of supporting the said core (4), - a coolant pump (7) for circulating the said coolant (25) in the said main vessel (100), the said reactor being characterized in that the said core support means (6) comprise a first orifice (15) for the passage of the said pump (7) so that the said pump (7) delivers the said coolant (25) into the said support means (6).
