Abstract
Integrated nuclear reactor cooled by a liquid metal and incorporating a main vessel sealed in its upper part by a slab, an inner vessel containing the core, the latter resting on a system for the positioning and supply of the core with liquid metal and which is called the support, the latter itself resting on a supporting structure bearing on the bottom of the main vessel of the reactor, wherein it comprises an inner baffle cladding the side wall and bottom of the main vessel and defining with the latter an intermediate space filled with the liquid metal, tubes for supplying a liquid metal to the intermediate space below the bottom of the main vessel and tubes for returning said liquid metal to an auxiliary exchanger in order to remove heat from the intermediate space.
Claims6
A nuclear reactor cooled by a primary liquid metal and comprising:
- a main vessel having a bottom wall and a side wall, a slab sealing said main vessel, a core, an inner vessel within said main vessel and containing said core, a support for positioning and supplying said core with said primary liquid metal, a supporting structure bearing on said bottom wall and supporting said support, at least one main exchanger and at least one primary pump suspended from said slab, said reactor further comprising a baffle located in the main vessel and cladding said side wall and said bottom wall to define with said main vessel an intermediate space filled with said primary liquid metal, tubes located within said intermediate space for supplying from an auxiliary exchanger a cooling liquid metal to a part of said space defined between said baffle and said bottom wall of the reactor vessel, and tubes located within said intermediate space for returning said cooling liquid metal to said auxiliary exchanger, in order to remove heat from said intermediate space.
