A core energy plant with closed working gas circuit, in which within an or safety container there are arranged a reactor core of pre-stressed concrete for heating the working gas, a working gas driven turbo-set with generator, and other components of the working gas circuit such as heat exchanger and gas storage means. The reactor core is separated from the turbo-set and other components and is arranged in a separate reactor chamber with walls of pre-stressed concrete, while the other components are respectively arranged in separate chambers, within an inner concrete container which has chambers for receiving the turbo-set with generator and the remaining components of the working gas circuit and which has its outer wall arranged adjacent the vertical inner wall of the outer safety container there is provided a recess for a pre-stressed concrete container for receiving the reactor core.

Core energy plant with closed working gas circuit

A gas-cooled nuclear reactor whose nuclear-fuel elements are constituted by graphite-encapsulated nuclear fuel particles and have graphite coatings is shut down in accordance with the present invention by introducing into the primary coolant gas circulation, a gadolinium-containing substance which is dispersed in the primary cooling gas before the latter enters the space between the fuel elements within the reactor core so that the gadolinium-containing substance is at least partly deposited on the free graphitic surfaces of the fuel elements.

Method of and apparatus for shutting down a gas-cooled nuclear reactor

A nuclear power-generating installation comprises three power-generating bines which are operated by three partial gas streams heated in separate passages of a nuclear reactor. After traversing the power-generating turbines the partial gas streams are cooled in respective recuperative heat exchangers to recover residual useful heat therefrom and are combined into a lesser number of gas streams each of which is subjected to at least two compression stages with at least one intervening cooling stage in which all of the gas is combined to flow as a total gas stream through at least one such cooler. Following the last compression stage the gas is again subdivided into three partial streams for preheating in the aforementioned recuperative heat exchangers before traversing the nuclear reactor for the main heating.
