The internal shell (6) of the nuclear reactor comprises at least one cylindrical sleeve (10) with a vertical axis. An annular enclosure (20) is arranged on the internal periphery of the cylindrical sleeve (10), at the top part thereof. The enclosure (20) is open upwards and delimited by a cylindrical secondary sleeve (21) arranged coaxially and inside the cylindrical sleeve (10) of the internal shell. The top end of the secondary sleeve (21) is located below the high level (14a) of the liquid metal inside the internal shell (6). An annular base (22) is fixed to the bottom end of the secondary sleeve (21) and onto the internal surface of the cylindrical sleeve (10) of the internal shell (6), below the low level (14b) of the liquid metal.
