A liquid-metal-cooled nuclear reactor includes a main vessel containing a primary fluid and a cylindrical separation structure, separating a hot leg from a cold leg. The cold leg encompasses the hot leg. At least one opening is provided in the cylindrical separation structure to enable the primary fluid to flow from the cold leg to the hot leg. A core is submerged in the hot leg. The reactor also includes at least one heat exchanger having an inlet from the hot leg and an outlet to the cold leg for transferring heat from the primary fluid to a secondary fluid of an externally connecting circuit. A reactor lid covers the main vessel. A gas plenum is disposed beneath the reactor lid and above the hot leg. An inner lid is disposed beneath the reactor lid covering the cold leg. The hot leg is open ended towards the gas plenum.
