Nuclear facility with a closed working-gas cycle

To increase the safety of a nuclear-reactor installation with closed working-gas cycle, it is suggested to provide a concrete vessel with many chambers which lies close to the vertical inner face of the outer prestressed-concrete containment with its outer wall. The concrete vessel contains the turboset including the generator as well as all other installation components connected by means of gas tubes to the reactor core placed in a special prestressed-concrete vessel. The chambers are supplied with closures which are gas-tight and safe concerning the escape of radioactive substances. The concrete walls protect against destruction and radioactive radiation, overflow valves in the separation walls of the chambers provide for pressure regulation in the case of a rupture of gas-conducting parts.
