Nuclear power plant with closed working-gas circuit

A nuclear power plant with a closed working-gas circuit is proposed in which relatively small components easy to manufacture and to handle can be used which can be repaired resp. exchanged without great effort. The characteristic feature is that each turbo-generator set and the adjoined components form one constructional element. These constructional elements are radially arranged around the nuclear reactor and connected with it each by a supply and a discharge line for the working gas. Each contructional element is arranged in a separate chamber provided within the reactor pressure vessel and is surrounded by single chambers made of ordinary concrete which are arranged around the pressure vessel.
