The concrete vault roof of a liquid metal cooled fast reactor is provided with a heat-insulating lining plate and has a central passage for rotating shield plugs surrounded by passages for heat exchangers and pumps. An annular plate of relatively small thickness is placed horizontally beneath the vault roof and its external edge is joined to the lining plate by means of shaped members having a long radius of curvature so as to form closed spaces for trapping an inert gas. The free edges formed by the openings in the annular plate are joined to the lining plate by means of a sealing shell.
